Answer:
Subtract the mass of the cylinder from the mass of the cylinder when it contains gasoline. This is the mass of the gasoline. Divide this figure by the volume, 100 ml, to get the density.
Explanation:
We know that if
e = 1 then collision is called perfectly elastic collision.
0<e <1 then collision is called partial elastic collision.
e =0 then collision is called inelastic collision.
So when two automobile collide then they usually do not stick together then this collision is called as elastic collision.
When object collide head to head it become more dangerous than other type of collision because when object come toward each other and due to suddenly velocity of object become zero due to this it produce large amount of force.Usually this force produce two time more as compare to when object moving in same direction.
A. directly convert hydrogen to electricity
Auto mechanics use them for both electric and hybrid cars, MRI technicians use them to look inside a patient's body when giving them an MRI scan, and robotic engineers use them also where the electromagnets power the motor and cause the robot to move.
Answer:
12.974 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
g = Acceleration due to gravity = 9.81 m/s²
= Coefficient of friction =0.66
a = Acceleration =
Car's original speed before braking was 12.974 m/s
