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.
The table shows experimental data of the magnitude of four forces exerted on a 2kg object as it slides across a horizontal surface. Which of the following could represent the magnitude of the net force that is exerted on the object? Select two answers.
Answer:
6N and 10N
Explanation:
The forces acting along the horizontal axis arw the horizontal force applied and the frictional force.
Frictional force is a force that opposes the horizontal force (moving force)
First we need to get the sum of force along the horizontal as shown
\sum Fx = Horizontal force - frictional force
\sum Fx = 8N - 2N
\sum Fx = 6N
Hence one of the magnitude of the net force exerted on the object is 6N
For the forces along the vertical component;
The forces are the weight, force of gravity(acting downward) and the normal force acting upward
Given
Weight = mass × acceleration die to gravity
Weight = 2×10 = 20N
Normal force = 10N
\sum Fy = (weight)-normal force
\sum Fy = (20)-10
\sum Fy = 20-10 = 10N
Hence the other net force acting on the object is 10N
The required options are 6N and 10N

Answer:
Work is defined as the process of energy transfer to the motion of an object through the application of force. This is usually represented as the product of force and displacement. The SI unit of work is Joule.
Explanation:
Power is defined as the amount of energy transferred in unit time. The SI unit of power is the watt. One watt is equal to one joule per second. Power is a scalar quantity.
I believe
Work is the method of the conversion of energy by the application of force to the motion of an object. Power is the unit-time sum of energy transmitted.

When you must add three vectors together, what is not true this process? You must only give a magnitude of the resultant vector It does not matter what order you add the vectors You can move the vectors parallel to each other You must connect the head of each vector with the tail of the next vector
The addition of any numbers of vector provide the magnitude as well as the direction of the resultant vector, hence the mentioned first option is not true.
The addition of vector required to connect the head of the one vector with the tail of the other vector and any vector can be moved in the plane parallet to the previous location, so, the mentioned second and third options are true.

the product of the charges indicates a negative force
the sum of the charges indicates a negative force
2. One particle has a negative charge, while another particle is neutral. Which statement describes the electrostatic force between these two particles?
There would be no electrostatic force because the sum of the two charges is 0.
The electrostatic force is attractive due to the particle with negative charge.
There would be no electrostatic force because the product of the two charges is 0.
The electrostatic force is repulsive due to the particle with negative charge.
3. How would the electrostatic force change if Coulomb's law included a negative sign?

What is the value and the direction of an electric field at a distance of 2.5 m from a +1 nC charge?
approximately 145 V/m directed away from the positive charge
approximately 145 V/m directed toward the positive charge
approximately 1.45 V/m directed away from the positive charge
approximately 1.45 V/m directed toward the positive charge
Answer:
The product of the charges indicates a negative force
There would be no electrostatic force because the product of the two charges wld be zero
Like chargers wld attract, and opposite charges wld repel
Approximately 1.45 V/m directed away from the positive charge
Explanation:
According to Coulomb's law the electrostatic force is directly proportional to the product of the charges and inversely proportional to the distance separating them.
According to Coulomb's law;
F =[tex]Kq1q2/r^2\\[/tex]
Where;
K = constant of Coulomb's law
q1 and q2 are the respective magnitudes of the charges
r = distance separating the charges
Hence,according to Coulomb's law, the product of the charges indicates a negative force.
According to Coulomb's law, for a negative charge, and a neutral particle, there would be no electrostatic force because the product of the two charges is 0. If Coulomb's law included a negative sign then Like charges would attract, and opposite charges would repel.
The electric field is given by the formula;
[tex]E = kq/r^2\\k= 9 * 10^9 Nm^2C-2\\q =1 * 10^-9 C\\r = 2.5 m\\E = 9 * 10^9 Nm^2C-2 * 1 * 10^-9 C/( 2.5 m)^2\\E = 1.45 V/m[/tex]
The direction of the electric field is 1.45 V/m directed away from the positive charge.

In a complete description of a force vector, which is usually not necessary?
O A. magnitude
O B. direction
OC. type
O D. units
In the complete description of a force vector, type is usually not necessary. Thus, the correct option is C.
What is Force vector?A force vector is a representation which has both the magnitude and direction of the force. Such a vector is typically represented through an arrow in the direction of the force applied and with a length which is proportional to the magnitude of the force.
If a force is applied on an object, this causes movement of the object in a given direction and the wind applies a force on it at an angle, and the new motion will be as that of a force which was applied in that direction.
Therefore, the correct option is C.

15 percent input work is lost due to friction,then what is the efficiency of machine?
Answer:
{ (x/y )*100 } - 0.15 y
Explanation:
The efficiency of a machine is the percent of output work divided by input work minus work lost from friction and heat.
Assume work output = x
Assume work input percent as =y
Work lost through friction is given as : 15% input work = 0.15 y
Then efficiency of the machine will be :{ (x/y )*100 }- 0.15 y
Use real values for x and y to find the correct efficiency of the machine.

A car is driving down the highway at a 50 m/s. Suddenly, the driver sees an accident and slams on his breaks, coming to a complete stop in 10 seconds. How far did the car travel before coming to a stop?
Given parameters:
Speed of the car = 50m/s
Time = 10s
Unknown:
Distance traveled before the car stopped = ?
We need to establish speed - time - distance relationship.
Speed is the rate of change of distance with time. It is a scalar quantity .
Mathematically;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
Input the parameters and solve;
Distance = 50 x 10 = 500m
The car traveled 500m before it stopped.
