A compass needle is a permanent magnet, which itself reacts to the permanent magnet in the earth's axis. Unfortunately, the fields of permanent magnets are very hard to calculate, and require an understanding of complex ferromagnetic phenomena, belonging as much to atomic theory as to electromagnetism.
We have that the new speed after she picks up her child is mathematically given as
V2=3m/s
<h3>
Speed</h3>
The speed of a body is simply the rate at which the body moves or functions, the speed of a body is measured with an SI unit of m/s.
Generally the equation for the Velocity is mathematically given as
m1v1=m2v2
Therefore
V2=3m/s

v_f=0
(1)
having into account that the total time spent in air till the cap came to her hands is Ttotal=2*t
where t is the time which the cap spent to reach the heighest point or the maximun height. so;
Ttotal=2second
t=1sec
we then replace t into the equation(1);
this is the initial velocity with which the cap was thrown
Answer:
Explanation:
From the question we are told that
Force F=39400
Initial speed
Distance
Generally the equation for acceleration is mathematically given by
Generally the equation for mass is mathematically given by
