False. The force comes first as in tapping or hitting a balloon. Then comes the motion and that might be the balloon dating in the direction it was shoved.
<h3>2.<u> Answer;</u></h3>
Momentum
<h3><u>Explanation;</u></h3>
- <em><u>Momentum refers to mass in motion, which means that objects that have mass and are in motion, will posses momentum, that is, they have their mass in motion. </u></em>
- <em><u>Momentum is given as the product of velocity of an object and its mass. Therefore, the amount of momentum possessed by a moving object or body is the product of mass and velocity. That is; p = m × v</u></em>
- From the equation, momentum is directly proportional to both mass and velocity.
<h3>3. <u>Answer;</u></h3>
Momentum
<h3><u>Explanation;</u></h3>
- <em><u>During collision, a force acts upon a body for a given amount of time change the velocity of an object. Product of force and time is called impulse</u></em>. The product of mass and velocity change is the change in momentum.
- <em><u>During collision the momentum change experienced by one object is equal in magnitude and opposite in direction to the momentum change experienced by the other object in collision.</u></em>
- That is; M1V1 =M2V2
<h3>4. <u>Answer; </u></h3>
= 250 kgm/s
<h3><u>Solution and explanation;</u></h3>
- <em><u>Momentum is given as the product of velocity of an object and its mass. </u></em>Therefore, the amount of momentum possessed by a moving object or body is the product of mass and velocity.
- That is; p = m × v
- mass = 50 kg, velocity = 5 m/s ; thus momentum will be;
- p = 50 × 5 = 250 kgm/s
Therefore, <em><u>momentum of the ice skater will be; 250 kgm/s</u></em>
Answer:
10 Hz
Explanation:
Frequency of wave is given by
f= v / lambda
f= 30 / 3
f= 10
D. Neutrino
Neutrinos are particles that rarely interact with matter.
<u>Opinion on Water Conservation </u>
<u> Fresh water sources is always increasing because of population and industry gowth, Even though water eventually returns to Earth through the water cycle, it's not always returned to the same spot, or in the same quantity and quality. By reducing the amount of water we use, we can better protect against future drought years. Saving water can help others with needs of it </u>
