Answer:
Acceleration of the car is .
Explanation:
It is given that,
Initial speed of the car, u = 29 m/s
Finally it reaches a speed of, v = 34 m/s
Distance, d = 110 m
We need to find the acceleration of the car as it speed up. It can be calculated using third law of motion as :
So, the acceleration of the car as it speeds up is . Hence, this is the required solution.
Answer:
(D) all of the above
Explanation:
All of the choices describe matter.
The correct answer is amplitude
-- There is nothing on the list of choices that you provided that has no mass.
-- There are no "things" that have no mass. Every sample of a liquid, a gas,
or a solid has mass, even if it's only an atom or two.
I think the only possible items you could name that have no mass would be
spiritual, conceptual, or sensory ones, like maybe ...
-- idea
-- conviction
-- belief
-- concept
-- image
-- sound
-- illusion
-- impression
-- agreement
-- inclination
-- tendency
-- sparkle
-- tingle
-- pain
Things like that.
It is called the "nucleus". most of its weight is concentrated at nucleus. It is held by the "strong nuclear force",because of the repulsive nature of both like charges of protons.
