<h3><u>Mass of an object affect the outcome of unbalanced forces:</u></h3>
Newton’s second law of motion deals with the result of motion of an object when unbalanced forces are applied. The second law of motion establish the relationship between mass, acceleration and unbalanced forces of the object. The below points explains the relation between unbalanced forces acting on mass of the object. The acceleration of object would be higher when the unbalanced force is higher.
The equation for the unbalanced force is,
For Example: Two masses of 500 kg and 1 kg is applied with same unbalanced forces. The change in motion of 500 kg would be very much less than the change in motion of 1 kg.
Answer:
yes for both.
Explanation:
according to Newton's first law an object in motion will stay in motion until acted on by an outside force and an object at rest will stay at rest until acted on by an outside force. this means that an object that is moving will stay moving in the direction that it's moving and at the same speed unless there's an outside force acting on it and it will keep in motion until there is an outside force acting on it.
Explanation:
Problem 1.
Initial speed of the runner, u = 0
Acceleration of the runner, 
Time taken, t = 100 s
Let v is the speed of the runner now. Using the first equation of kinematics as :
v = 420 m/s
Problem 2.
Initial speed of the plane, u = 0
Distance covered, d = 300 m
Time taken, t = 25 s
Using the equation of kinematics as :
Problem 3.
A ball free falls from the top of the roof for 5 seconds. Let it will fall at a distance of d. It is given by :
d = 122.5 meters
Let v is the final speed at the end of 5 seconds. Again using first equation of kinematics as :
v = 49 m/s
Hence, this is the required solution.
Answer:
Black bodies are good absorber of light waves from the sun, while shining surfaces are good reflector of the light waves.
Explanation:
Generally, a black surface or material tends to absorb light waves while under the sun, while a shiny surface is a good reflector of the waves. This is because the black material is a good absorber, and also a good emitter.
The shiny necklace can only absorb little light waves from the sun, thus it reflects most of the light waves. The reflection is the reason for the small circles of light seen around the yard.
However, when in a cool environment the black shirt would cools faster (good emitter) than the shiny necklace.
