When a bowling ball strikes a bowling pin, they impart equal forces upon the other.
The correct option is (a) Equal forces
Newton's third law of motion:Newton postulated that whenever objects A and B interact, they exert forces on one another. You put a downward force on the chair when you sit on it, and the chair responds by exerting an upward force on your body. This contact creates two forces: one force on the chair and one force on your body. These two forces—also known as the action and reaction forces—are covered by Newton's third law of motion. There is an equal and opposite response to every action, according to the formal statement of Newton's third law.There are always two forces acting on the two interacting objects, according to the statement's interpretation. The amount of the force known as the action and reaction forces—are covered by Newton's third law of motion. There is an equal and opposite response to every action, according to the formal statement of Newton's third law.There are always two forces acting on the two interacting objects, according to the statement's interpretation. The amount of the force exerted on the first and second objects are equal. In contrast to the force acting on the second item, the force on the first object is operating in the opposite direction.

The difference of two numbers is 28. Find the number if the larger is 3 times smaller.
Answer:
14,42
Explanation:
Let the smaller number be x
Hence, the larger number = 3x
Hence,
[tex]3x-x=28\\2x=28\\x=14[/tex]
Hence, the smaller number = x = 14
The larger number = 3x = 42

Why do electrons flow in a circuit
Answer:
When a negative charge is brought near one end of a conductor electrons are repelled. ... When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.

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]

A dog barks in a park and hears its echo after 0.5 seconds. The sound of its bark got reflected by a nearby building. The sound of speed in air is 346 m/s. The distance between the dog and the building is
Answer:
the answer is 173 m/s
Explanation:
the the sound traveled from the dog to the building and back to the dog in 0.5 seconds, every second passes the sound travels 346 m/s but if half a second passes then we divide 346 by 2 and get 173 m/s.

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.
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]

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?
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
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?
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.

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.
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.
