Answer:
the diver's speed is independent of the launch height.
Explanation:
For this exercise we must use Newton's second law
fr - W = m a
the friction force has the general form
fr = b v
Let's analyze this equation to find out what happens with the speed of the distant club.
When jumping, the initial speed is zero, so the friction force is zero and has an acceleration equal to the acceleration of gravity, as the speed increases the friction force increases decreasing the acceleration until it becomes zero, when it arrives at this value the velocity it has is called terminal velocity and this velocity remains fixed in relation to the trajectory.
fr = W
v = cte
The distance or time in which this equilibrium is reached is relatively fast, so the diver's speed is independent of the launch height.
The basic relationship between mass m, volume V and density d is given by
re-arranging the equations and using m=1 kg and
, we find the volume:
and since
, this corresponds to
of air.
Answer:
The magnetic field will help to create an electromagnetic radiation which will prevent the charged particle from moving in a constant direction in a straight path.
Explanation: A magnetic field is an area around a particle where magnetic energy is felt or experienced, this ensures that all the charged particle within the magnetic field will be influenced by magnet.
In the highlighted situation, the magnetic field will help to ensure that an electromagnetic radiation is created to synchrotron radiation occurs effectively.

Answer:
Newton
Explanation:
The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.
Force is the product of mass and acceleration of a body.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
So;
1N = 1kgm/s²
Therefore, the unit of force is newtons and 1N is equal to 1kgm/s²
