A value that describes how heavy an object is and is related to the force of gravity is
2 answers:
The heaviness of an object with the relation to force of gravity, is described by the ‘weight’
<u>Explanation: </u>
The heaviness of the object is referred to the mass of the object. When the mass of the object is concerned it is taken in space or vacuum where force of gravity do not exist.
Therefore, to value the actual heaviness of the object, mass is multiplied by the component of force of gravity, is termed as weight.

Answer:
0.39
Explanation:
Parameters given:
Mass of car, m = 940 kg
Speed of car, v = 11.8 m/s
Power supplied by engine, P = 4300 W
To get the acceleration, we must define the relationship between Power and velocity.
Power, P, is given in terms of velocity, v, as:
P = F * v
where F = force
This is because Power is given as:
(where E = energy. t = time taken, d = distance moved)
Force, F, is given as:
F = m*a
Therefore, Power will be:
P = m * a * v
Acceleration, a, will then be:
The acceleration of the car at that time is 0.39
Heat always flows from higher temperature to lower temperature. So option A. heat will flow from the air into the coolant is the correct answer.
