By collapsing and crumpling, the force and energy is absorbed by the crumple zone and it is not transferred to the passengers inside. This is a safety feature for the passengers.
Answer:
the angular acceleration of the car is 1.5 rad/s²
Explanation:
Given;
initial angular velocity,
= 10 rad/s
final angular velocity,
= 25 rad/s
time of motion, t = 10 s
The angular acceleration of the car is calculated as follows;

Therefore, the angular acceleration of the car is 1.5 rad/s²
Answer:
The volume at the surface is 10.97 L.
Explanation:
Given that,
Volume = 5.5 L
Height = 10 m
Density of sea water= 1025 kg/m³
We need to calculate the pressure at that point
Using formula of pressure

Put the value into the formula


We need to calculate the volume at the surface
Using equation of ideal gas

So, for both condition

Put the value into the formula


Hence, The volume at the surface is 10.97 L.
Because mass does not change from place to place but weight does change from place to place... why? because weight is the amount of gravitational force on an object and mass is the amount of matter in an object. mars has less gravitational force so an object will weigh less than it really weighs there
