Answer:
Increase
Explanation:
The plane strain fracture toughness of a metal is expected to increase with rising temperature.
Answer:
Time and velocity
Explanation:
The time taken for the velocity to double is very important to find the amount of acceleration the car acquires.
Acceleration is the rate of change of velocity with time.
Acceleration =
v is the initial velocity
u is the final velocity
t is the time taken
So, the velocity and time is needed to calculate the value of the acceleration the car undergoes.
It's a change of motion, in simple terms.
