The force is applied to the accelerating object that has a constant mass. Option A is correct.
<h3>
What does Newton's second law of motion state?</h3>
The force applied to the object is the product of its mass and acceleration.
Where,
- force
- mass
- acceleration
From the equation, the force and the acceleration are in a proportional relation. The mass is not changing as given in the question.
Therefore, the force is applied to the accelerating object that has a constant mass.

Answer:
Explanation:
Let the child is moving with speed same as the speed of water flow
So here the position of child with respect to flow must be zero
And if the boat start at an angle with the vertical
so its relative speed with flow of water is given as
now the time to reach the child is given as
so now we have
So the time to catch the child is given as
So distance moved by it in 0.104 h
distance moved by the boat in upstream direction given as
In y direction the displacement of boat is
net displacement of the ball is given as
Answer:
Continental drift theory describes the long term effect of plate tectonics.
Explanation:
The long term result of plate tectonic movement is the continental drift. The continents of Earth lay on tectonic plates, that are in motion and interaction via plate tectonics. The drift of the Earths continent is an ongoing process evident in the rift valleys and seafloor spreading zones.
The theory that the Earth's continents are dynamic and have drifted relative to each other is known as continental drift which correlates with the theory of plate tectonics.
Every year, the Earth's outer shell plates are displaced by a small amount due to the heat coming from the Earths interior via convection currents.
