The car's acceleration will be 0.575 m/s².The unit of acceleration is m/sec².
<h3>What is acceleration?</h3>
The rate of velocity change concerning time is known as acceleration.
Given data;
Initial velocity, u= 0 m/s
Final velocity, v= 4.2 m/s
Time elapsed, t = 7.3 seconds.
To find ;
Acceleration, a
The acceleration when the change in velocity is observed by the formula as:
a= (v-u)/(t)
Substitute the given values:
a= (4.2-0)/(7.3)
a=(4.2)/(7.3)
a= 0.575 m/s²
Hence, the car's acceleration will be 0.575 m/s².

A because water has more volume when it's warmer
There can be someone who think answer should be B but temperature isn' proportional with heat. The formula is Q=m.c.t , so it isn't definetly temperature. So answer should be D. Because A and C connect with force etc.
Answer: 11
Explanation: In addition to nuclear reprocessing units at Sellafield and Urenco's Tails Management Facility (TMF) in Capenhurst, the UK has 11 active nuclear reactors in five locations (10 advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR)).

Answer:

Explanation:
G = Gravitational constant
M = Mass of planet
R = Radius of planet
Acceleration due to gravity on first planet

Assuming that the planets have the same mass density 
Density of first planet

Density of second planet

Acceleration due to gravity on the second planet

The acceleration due to gravity of the planet would be
times the acceleration due to gravity on the first planet.
