Answer:
The thread will experience a force on it .
Explanation:
When thread is tied to pen it will experience force. Because the pen is Abit heavy , there is a force that is applied to it which will cause it to elongate , after a while the thread will stretch, elongate and can later experience deformation. When it experience that, the thread can break after deformation and it has losses it elasticity.
The height of the ball after the given time of motion is 3.275 m.
The given parameters;
- initial velocity of the ball, u = 4 m/s
- height of fall of the ball, h = 2.5 m
- time of motion, t = 0.5 s
The distance traveled by the ball is calculated as follows;
Thus, the height of the ball after the given time of motion is 3.275 m.

Answer:
option "c" is correct
Explanation:
Physical science or Physics is the study of matter, energy and their mutual relationship.
The magnitude of the average force that the ball exerts against his glove is 600 N
<h3>Further explanation</h3>
Newton's second law of motion states that the resultant force applied to an object is directly proportional to the mass and acceleration of the object.
F = Force ( Newton )
m = Object's Mass ( kg )
a = Acceleration ( m )
Let us now tackle the problem !
<u>Given:</u>
mass of ball = m = 0.15 kg
initial speed of ball = u = 40 m/s
final speed of ball = v = 0 m/s
distance = d = 20 cm = 0.2 m
<u>Asked:</u>
average force = F = ?
<u>Solution:</u>
<em>We will use </em><em>Newton's Law of Motion</em><em> to solve this problem as follows:</em>

The statement that best explains the movement of electric current is that the ground is positively charged and the clouds are negatively charged.
<h3>What is lightning storm?</h3>
Lightning storm can be defined as the electrical outlet that occurs due to unsteadiness of the storm clouds and the ground.
Lightning storm occurs when opposite charges build up enough in the air leading to rapid discharge of electricity.
