Momentum
<h2>
Explanation:
</h2>
The momentum of a particle is defined as the product of the particle mass and the particle velocity as follows:

On the other hand, the impulse of a constant force is defined as:

We also know that the net force acting on a particle equals the rate of change of the particle’s momentum, so:

If the force is constant, then
equals the total change in momentum over a period of time:

Answer:
The focal length of eye piece is 6.52 cm.
Explanation:
Given that,
Angular Magnification of the microscope M = -46
the distance between the lens in microscope L= 16 cm
The focal length of objective f₀ = 1.5 cm
Normal near point N = 25 cm
Have to find focal length of eye piece f ₙ =?
The angular magnification is given by
M ≈ - (L-fₙ)N/f₀fₙ
Rearranging for fₙ
fₙ =L(1 - Mf₀/N)⁺¹
=18/2.76
fₙ = 6.52 cm
The focal length of eye piece is 6.52 cm.
Answer:
F(of gravity) = MA
F(normal force) = MA * cos(angle)
F = 72 * 9.81 * cos28
Don't have a calculator, so can't really do all the math right there. So just plug that in
