5 0

Answer:

As speed of a particle has a limit so does its momentum has a limit.

Explanation:

As we know that in this Universe no information can travel faster than the speed of light.

The speed of light is the fastest possible speed and hence the quantities dependent on it also have certain limits.

The momentum of a body at normal non-relativistic speed is given as:

p=m.v

The momentum of a body at relativistic speed (a speed of the order of speed of light) is given as:

p=m.v.\gamma

here

\gamma =\frac{1}{\sqrt{1-\frac{v^2}{c^2} }}  Lorentz factor

A woman falls to the ground while wearing a parachute. The air resistance on the parachute of the parachute is 500N. If the woma
scoundrel [369]

The gravitational force on the woman is A) 500 N

Explanation:

There are two forces acting on the woman during her fall:

  • The force of gravity, F_G, acting downward
  • The air resistance, F_D, acting upward

According to Newton's second law, the net force acting on the woman is equal to the product between the woman's mass and her acceleration:

\sum F=ma

where m is the mass of the woman and a her acceleration.

The net force can be written as

\sum F = F_G - F_D

Also, we know that the woman falls at a constant velocity (5 m/s), this means that her acceleration is zero:

a=0

Combining the equations together, we get:

F_G-F_D = 0

which means that the magnitude of the gravitational force is equal to the magnitude of the air resistance:

F_G=F_D=500 N
