A force of 16 N to the west is applied to each object below. Which object will undergo the greatest change in momentum
Answers
A force of 16 N to the west is applied to each object below , the object with greater mass and velocity have greater momentum. So, A 20 Kg object that is moving east at 10m/s.
What is force?
Force is an external agent acting on a body, to change it from the state of rest or motion. There are various kinds of forces such as frictional force, magnetic force, nuclear force etc.
In physics, force is the product of mass and acceleration of the body. Greater mass results greater force needed to be applied on the object to make it move or stop.
Momentum is the product of mass and velocity. Thus, as mass or velocity or both increases, momentum of the object increases. Hence the larger object moving faster will gain greater momentum.
Here, option C is the correct answer.

A freeway exit curves with a radius of 30 m and a posted speed limit of 17.5 m/s. What is your radial
acceleration if you take this exit at the posted speed?
Answers
Answer:
10.21m/s²
Explanation:
Radial acceleration, also known as centripetal acceleration, refers to the acceleration of an object along the circular radius. It can be calculated using the formula:
a(r) = v²/r
Where a(r) = radial acceleration
v = velocity
r = radius of the circular path
According to the information provided in the question, velocity (v) = 17.5m/s, radius = 30m. Hence;
a(r) = v²/r
a(r) = 17.5²/30
a(r) = 10.208333
a(r) = 10.21m/s²
Lenny wrote the steps he used to find the mass of an object with 400 J of energy moving at a velocity of 8 m/s.
1. Find the square of 8 m/s, which is 64 m2/s2.
2. Divide kinetic energy, 400 J, by 64 m2/s2, which is 6.25 J per m2/s2.
3. Divide 6.25 J per m2/s2 by 2 to get a mass of 3.125 kg.
Which best describes Lenny’s error?
A. In Step 1, he should have found the square root of 400 J instead of squaring 8 m/s.
B. In Step 1, he should have multiplied 8 m/s by 2 instead of squaring it.
C. In Step 2, he should have divided 64 m2/s2 by 400 J instead of dividing 400 J by 64 D. m2/s2.
In Step 3, he should have multiplied 6.25 J per m2/s2 by 2 instead of dividing it by 2.
Answers
Answer:
In Step 3, he should have multiplied 6.25 J per m2/s2 by 2 instead of dividing it by 2.
Explanation:
D. In Step 3, he should have multiplied 6.25 J per m2/s2 by 2 instead of dividing it by 2.
What is Kinetic energy?The energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
According to the question,
The object posses an kinetic energy,
Given Mass of an object = 400 J
Energy moving at a velocity= 8 m/s.
[tex]E_k =\frac{1}{2} mv^2\\\\=400J = \frac{1}{2} *m(8)^2\\\\\\=\frac{400J}{64m^2/s^2} = \frac{1}{2}*m\\ \\ =6.25 *2 = m\\\\=12.25 kg[/tex]
Hence,
In the step 3 ,he should have multiplied 6.25 J per m²/s² by 2 instead of dividing it by 2.

Introduction This section describes the principles and concepts related to the experiment. It is used to help the person reading your report to understand the information that serves as foundation for the experiment. It also includes a brief statement about the purpose of the lab. Example: Surface tension is the attractive force exerted upon the surface molecules of a liquid by the molecules beneath. Water has a high surface tension because there are strong attractive forces between water molecules. Adding surfactants, like soap, can reduce the surface tension of a liquid. The purpose of the experiment was to determine the effect of soap on the surface tension of water.
Answers
Answer:
See explanation
Explanation:
It is a common observation that when water drops on a clean glass surface, it appears as little bags of water.
Surface tension makes water surface act like a stretched elastic skin bag.
Surface tension is caused by attractive forces between the molecules at the surface and the molecules in the bulk of a liquid. Remember that the forces of cohesion between water molecules are very strong.
When surfactants such as soap are added to water, the surface tension of water is decreased, hence the experiment.

Answers
Answer:
a) Vf = 13.87[m/s]
b) t = 1 [s]
Explanation:
a)
To solve this problem we can use kinematics equations:
[tex]v_{f}^{2}= v_{i}^{2}+(2*g*h)[/tex]
where:
Vf = final velocity [m/s]
Vi = initial velocity = 4 [m/s]
h = elevation = 9 [m]
g = gravity acceleration = 9.81 [m/s^2]
[tex]v_{f}=\sqrt{(4)^{2} +(2*9.81*9)}\\v_{f}=13.87[m/s][/tex]
b)
Now using the next equation we can find the time
[tex]v_{f}=v_{i} +(g*t) \\t = (13.87-4)/9.81\\t=1[s][/tex]

Lynette has made it to the final round of a tennis tournament. While watching a match between two other players, she attributes her racing heart and rapid breathing to excitement. The next night, just before her own match, she attributes her racing heart and rapid breathing to nervousness. Which theory of emotion best explains this situation?
Answers
Answer: D. the Schachter-Singer theory
Explanation:
The Schachter-Singer theory which is also called the Two-factor theory of emotion, explains that humans feel emotion after they appraise the changes in their body in reaction to a stimuli as this would then give them a better means to tell which emotion they are feeling.
Lynette in the first instance noticed she had a racing heart and rapid breathing in response to watching two other players and was then able to appraise this and attribute it to excitement.
When the same thing occurs again but under different circumstances, she is able to appraise it differently and attribute it to nervousness which shows that the Schachter-Singer theory is the relevant theory.
