Water starts boiling and bubbling
<u>Explanation:</u>
When liquid or gas present in the warmer areas rise to the cooler part of the gas or liquid then it is termed as convection.The gas that is moved to the cooler areas tend to move to the warmer areas once again and this pattern occurs continuously. Boiling of water in a container is a better example of the convection currents. So Water starts boiling and bubbling represents transfer of heat through convection.
Answer:
The angle when it leaves is the same as the angle when it hits.
Explanation:
think of it as a mirror, mirrors show exactly what you display.
Answer:
4117.65 N
Explanation:
Speed of ball, u = 126 km/h = 35 m/s
Mass of ball, m = 160 g = 0.16 kg
Time interval, t = 1.36 ms = 0.00136 s
We can calculate the force as a measure of the momentum of the ball:
F = P/t
Momentum, P, is given as:
P = mv
Therefore:
F = (mv) / t
F = (0.16 * 35) / (0.00136)
F = 4117.65 N
The force imparted to the two glove d hands of the inexperienced catcher is 4117.65 N.
