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
Speed= distance/time
Speed= 150000m/7200s=20.83m/s(cor.to.2d.p.)
I think its inductance. If its not then I think its none of the above
<span>At this distance, and with an orbital speed of 24.077 km/s, Mars takes 686.971 Earth days, the equivalent of 1.88 Earth years, to complete a orbit around the Sun. This eccentricity is one of the most pronounced in the Solar System, with only Mercury having a greater one (0.205).
686.971 rounds to 687

Answer:
<h2>45 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 15 × 3
We have the final answer as
<h3>45 N</h3>
