Explanation:
The acceleration of the train is given by:
where:
u = 5 m/s is the initial velocity of the train
v = 45 m/s is the final velocity of the train
t = 8 s is the time taken for the train to increase the velocity
Substituting numbers into the formula, we find
Pop rocks and soda..... baking soda and vinegar ...
Answer:
The angular velocity is reduced when the body is fully stretched.
Explanation:
Divers keep there bodies as compact as possible just to increase the angular velocity.
When they extend their limbs to enter straight down the angular momentum helps them to dive. The angular velocity is reduced when the body is fully stretched and diver's inertia is also not reduced. Thus a streamlined shape is formed which helps to penetrate more deeper into the water.
The impact area is reduced when fully stretched body is entered in to the water.
