If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
Answer:
V = 0.074 m/s
Explanation:
given,
mass of the receiver, M = 96 Kg
mass of the ball, m = 0.42 Kg
initial speed of the ball, v = 17 m/s
initial speed of the receiver = 0 m/s
final speed.V = ?
using conservation of momentum
M u + m v = (M + m) V
0 + 0.42 x 17 = (96+0.42) V
96.42 V = 7.14
V = 0.074 m/s
hence, Speed after catching the ball is equal to 0.074 m/s

Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

A hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation of a particular scientific question emerged by observing the real world.
Hypotheses are explanations that must be tested (either confirmed or rejected) by using the scientific method.
In conclusion, a hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.
