More stopping force is required when the car has to stop in a shorter distance.
<h3>What is the relationship between force and acceleration?</h3>
Force is directly proportional to acceleration according to Newton's second law of motion.
This means that acceleration increases when force increases.
Stopping of a moving car is negative acceleration.
Therefore, more stopping force is required when the car has to stop in a shorter distance.

Answer:
It would be B because the warm air heats up and then burns the marshmallow. And the heat and the marshmallow were touching each other
Explanation:
The constant velocity that the spacecraft must travel is : 3.49 * 10⁸ m/s
<u>Given data :</u>
Distance of star from earth = 4.3 light years
Observers time = 3.7 years
<h3>Determine the constant velocity the spacecraft must travel </h3>
Observers time = 3.7 * 365 * 24 * 60 * 60
Distance of star from earth = 4.3 * 9.46 * 10¹⁵
The velocity the spacecraft must travel will be calculated using the equation
V = distance / time
= ( 4.3 * 9.46 * 10¹⁵ ) / ( 3.7 * 365 * 24 * 60 * 60 )
= 3.49 * 10⁸ m/s
Hence we can conclude that The constant velocity that the spacecraft must travel is : 3.49 * 10⁸ m/s

Answer:
Option (d)
Explanation:
The electrons in a conductor moves with the drift velocity when the electric current is flowing through the conductor.
The drift velocity is due to the applied electric field across the conductor.
