Answer:
The ratio is 1:1
Explanation:
Firstly we are told the in (a) we have a force which A given to be: FA
We are then told the are two other forces which a B and C which are equal.
These forces are given to be F and 19.5° away from A.
We are then told that the force on the elephant is now three times, of what it was when we only had force A.
Since we are told that B and C are eqaula.
If we say FA = 2N
Then in order for it to be three times, we would have to add 4N since it was the only force present at the time.
If we add two equal forces, then we can devide that 4 by 2.
We then find out that F =2N
and thus equal to FA.
Therefore the ratio of F/FA is
!:1

Answer:
The pendulum should be made longer by 0.194m in order to increase its period by 0.32s
Explanation:
using the formula T= 2π
rearranging the equation and making L subject of formula we have;
L=T²g/4π²
lets calculate the length when T=1.06s
g=9.8m/s² , π=3.124
L=0.279m
the new period after its increased by 0.32s = 1.06+0.32 =1.38s
increase in length = 0.473 -0.279
=0.194m
The only force acting on the ball, once it left the hand of the player, is the gravitational atraction of the earth. Once the ball reaches its maximum height, it starts a free fall movement under the action of earth's gravity.
Then the magnitude of the acceleration of the ball is the gravitational acceleration, g, approximatley 9.8 m/s^2
The direction in which the magnetic force is acting on the charge is upwards.
<h3>What is Magnetic force?</h3>
This is the attraction and repulsion which usually occurs during the motion of electrically charged particles.
In the magnetic field, the charge is moving to the left. Therefore the direction the magnetic force is acting on the charge is upwards which is gotten via right hand rule.
