What's your favorite
family/cultural tradition? Why is this tradition your
favorite?
Answer:
Every summer we go and work at a summer camp. My whole family loves it, and it's something that always brings us closer.
Explanation:
Christmastime is without a doubt my favorite time of year, not because of Christmas itself, but because of the atmosphere leading up to it. I've always felt this way, and I believe that is because of my grandmother. My Nanny was the same way. She loved Christmas, and went all out every year. Her house was put in the local newspaper several times because of all the lights and decorations she put up. If only they could have gone inside the house!
Anyway, there are a lot of things I did with my grandma around Christmas, and if I had been asked my favorite tradition when I was a young child, I might have said “decorating,” or “making Christmas treats,” but looking back, it is what we would do every Christmas Eve.
Christmas Eve is last-minute shopping day for the adults of my family, and the only shopping day for the kids. I would head out with my dad in the morning and shop, then go to lunch with my grandpa, and then finally, I would go with my grandma. We would shop a little, and then she would always buy some fake poinsettias. We would then travel to a tiny cemetery that seemed like an hour away back then, and I would walk with her to her father's grave.
Even as a young child, I felt the emotions in the air when we visited his grave. She never cried or showed any signs of sadness, but I could just sense how special the moment was to her. When her mother passed away in 2013, we went to visit both of them, and the atmosphere only intensified.
My grandma died in March of 2015 after a long battle with cancer. Every Christmas Eve, I buy the most beautiful poinsettias I can find, and visit her grave. It's always freezing outside, being December, but I stand for a few minutes, remembering, and then I get back in my car and head home.
My fondest tradition isn't the most fun, or the most festive. It's the one that means the most to me. One day, I hope I can take my children or grandchildren with me, and I hope they'll feel everything that I felt.
it takes you 30 minutes to walk an average velocity of 2.om/s south to school. What is your displacement?
Answer:
3600 m SOUTH
Explanation:
avg velocity= (change displacement)/(change in time)
2.0 m/s= x/ (1800 s)
displacement= (2.0 m/s * 1800s)= 3600 m SOUTH
.......
sign explanation
2.0 m/s south= -2.0 m/s (downwards direction)
-2.0 m/s= x/ (1800 s)
x= -3600 m
An observer is standing next to the tracks, watching a train approach. The train travels at 30 m/s and blows its whistle at 8,000 Hz as it approaches and then passes by the observer without slowing down. Assuming the speed of sound is 340 m/s, how much of a frequency change did the observer hear?
Answer:
The frequency heard by the observer will be "7351.35 Hz".
Explanation:
The given values are:
Source,
[tex]V_s=30 \ m/s[/tex]
Frequency of source,
[tex]F_s=8000 \ Hz[/tex]
Speed of sound,
[tex]C=340 \ m/s[/tex]
As we know,
⇒ [tex]F=(\frac{C+V_r}{C+V_s} )F_s[/tex]
Here,
[tex]V_r=0[/tex]
So that the formula will be:
⇒ [tex]F=(\frac{C}{C+V_s} )F_s[/tex]
[tex]=\frac{340}{340+30}\times 8000[/tex]
[tex]=7351.35 \ Hz[/tex]

In photosynthesis, what two compounds are produced during the light-dependent reaction then used in the light-independent reaction?
A) ATP and NADPH
B) ATP and ADP
C) NADP+ and ADP
D) NADPH and NADP+
Answer:
The answer choice is: A) ATP and NADPH
Explanation:
Your question is asking the components that are created during light - dependent reaction, and then used in independent reaction. That would be shown in the photo below!
ATP and NADPH is created from light dependent then transfered and transformed into different components from the calvin cycle (light independent cycle)
Two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH
Photosynthesis is a process that takes place in the Chloroplast of plant cells. Autotrophs obtain their energy source (food) in the presence of sunlight.
The photosynthesis process occurs in two distinct stages; light-dependent reaction and light-independent reactions.
the light reactions take place in the thylakoid membranes of chloroplasts.The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesisThese molecules are the energy storage molecule ATP and the reduced electron carrier NADPH.Thus, two compounds are produced during the light-dependent reaction then used in the light-independent reaction - A) ATP and NADPH

Explanation:
A runner is jogging in a straight line at a
steady vr= 8.4 km/hr. When the runner is
L= 6.3 km from the finish line, a bird begins
flying straight from the runner to the finish
line at vb= 42 km/hr (5 times as fast as the
runner). When the bird reaches the finish
line, it turns around and flies directly back to
the runner.
Answer:
Total distance traveled by bird is 10.5 km.
Explanation:
Given that,
Velocity of runner= 8.4 km/hr
Distance = 6.3 km
Velocity of bird = 42 km/hr
Suppose, How far does the bird travel?
We need to calculate the time of bird
Using formula of time
[tex]t=\dfrac{d}{v_{b}}[/tex]
Put the value into the formula
[tex]t=\dfrac{6.3}{42}[/tex]
[tex]t=0.15\ hr[/tex]
We need to calculate the distance runner travels during time period
Using formula of distance
[tex]d=v_{r}\times t[/tex]
[tex]d=8.4\times0.15[/tex]
[tex]d=1.26\ km[/tex]
We need to calculate the distance of runner to FL
Using distance
[tex]d'=6.3-1.26[/tex]
[tex]d'=5.04\ km[/tex]
We need to calculate the net closing speed between runner and bird
Using speed
[tex]v'=v_{r}+v_{b}[/tex]
[tex]v'=8.4+42[/tex]
[tex]v'=50.4\ km/hr[/tex]
We need to calculate the time for runner and bird to meet
Using formula of time
[tex]t=\dfrac{d}{v'}[/tex]
Put the value into the formula
[tex]t=\dfrac{5.04}{50.4}[/tex]
[tex]t=0.1\ hr[/tex]
We need to calculate the distance covered by runner
Using formula of distance
[tex]d=vt[/tex]
Put the value into the formula
[tex]d=8.4\times0.1[/tex]
[tex]d=0.84\ km[/tex]
We need to calculate the distance covered by bird to runner
Using formula of distance
[tex]d=vt[/tex]
Put the value into the formula
[tex]d=42\times0.1[/tex]
[tex]d=4.2\ km[/tex]
We need to calculate the total distance
Using distance
[tex]D=6.3+4.2[/tex]
[tex]D=10.5\ km[/tex]
Hence, Total distance traveled by bird is 10.5 km.
How can you find the frequency or period of ocean waves?
Answer: As you probably have seen in the ocean or a lake, the stronger the wind, the higher the waves. The period and wavelength can be expressed in terms of their reciprocals, the wave frequency ω = 2(pi)/T, and the wave number κ = 2(pi)/λ.
Explanation: To find the period, we solve for T=1f, given the value of the frequency (f=2s−1). T=12 s−1=0. 5 s. Since one definition of wavelength is the distance a wave has traveled after one complete cycle (or one period), the values for the wavelength (λ=0.9m) as well as the frequency are given.

Can an object experiencing constant acceleration change its direction of motion? Explain.
Answer:
Yes it can.
Explanation:
A object undergoing a constant acceleration has a constantly changing velocity. If the acceleration always points in the same direction as the velocity, the trajectory will be no different than if there were no acceleration, but in general acceleration will change the trajectory.
a sled with no initial velocity accelerates at a rate of 3.2 m/s squared down a hill how long does it take to sled to go 15 m to the bottom
Answer:
After 3.06secondsExplanation:
Given that the following data are
acceleration a= 3,2m/s^2
distance s=15m,
time t=?
Applying the formula for the equation of motion we have
s=ut+1/2at^2
we no initial velocity (u=0)
substituting our given values into the expression we have
15=0*t+1/2(3.2)t^2
15=1/2(3.2)t^2
15=3.2t^2/2
30=3.2t^2
t^2=30/3.2
t^2=9.375
Squaring both sides we have
t=√9.375
t=3.06seconds
It will take the sled 3.06 seconds to get to the bottom

A mass is dropped from a height h above the ground, and freely falls under the influence of gravity. Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling? Consider the "up" direction to be positive.
Which graph is it?
Answer:
B
Explanation:
The only force acting on the block is gravity, so the block has a constant, negative acceleration. This means the velocity of the block is decreasing at a constant rate, so the answer is B, D, or E. Velocity is the rate of change of displacement, and answer choice B is the only one that has a displacement graph that matches that idea.
Answer: Graph B here correctly describes the displacement and velocity of the object during the time the object is falling. Option B is correct.
It is given that the mass of an object is dropped from height 'h' above the ground and "up" direction is taken to be positive.
It is required to find the graph which describes the displacement and velocity of the object during the time the object is falling.
Which graphs here correctly describes the displacement and velocity of the object during the time the object is falling?If any body falls freely towards the ground, then its acceleration is decreasing constantly with respect to time. That means velocity of an object will also be decreased as shown in graph B. Also we know that velocity is the rate of change of displacement.
As it is given in question that up direction is positive then it is also considered that downward be negative means decreasing.
Therefore, both the quantities are decreasing. So graph B correctly describes the displacement and velocity of the object during the time the object is falling.

A man runs at 7.5 m s-1 due east across the deck of a ship which moves at 10.0 m s-1 due north. Determine the resultant velocity of the man( his velocity relative to the water)
Answer:
12.5 m/s North/east
Explanation:
I thought of it as a graph. I basically just found the distance between the points (0,0) and (10, 7.5)!
The resultant velocity of the man is 12.5 m/s.
What is velocity?The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.
Velocity of the man: v₁ = 7.5 m/s (due east )
Velocity of the ship: v₂ = 10 m/s. ( due north.)
Hence, the man and the ship move in perpendicular direction.
So, his velocity relative to the water = the resultant velocity of the man
= √(7.5² + 10²) m/s = 12.5 m/s.
Hence, resultant velocity of the man is 12.5 m/s.
