A physical therapy exercise has a person shaking a 5.00 kg weight up and down rapidly. if the barbell is moving at 4.50 m/s, wha
Ivanshal [37]

The magnitude of the force required to stop the weight in 0.333 seconds is 67.6 N.

<h3>Magnitude of required force to stop the weight</h3>

The magnitude of the force required to stop the weight in 0.333 seconds is calculated by applying Newton's second law of motion as shown below;

F = ma

F = m(v/t)

F = (mv)/t

F = (5 x 4.5)/0.333

F = 67.6 N

Thus, the magnitude of the force required to stop the weight in 0.333 seconds is 67.6 N.

How does the science of heat transfer differ from the science of thermodynamics?
mariarad [96]

Answer:

The science of thermodynamics deals with the fundamental laws that guide how physical processes occur in relation with the energy transfer. When a system or process changes from one state of equilibrium to another, thermodynamics is interested with the amount of heat transfer during the process. On the other hand, the science of heat transfer is simply about the rate of heat and temperature distribution inside a system at a particular point in time.

melomori [17]

Answer:

a=0.0947mm

Explanation:

Given data

λ=680nm

L=5.5m

ω=7.9cm=0.079m

To find

Width of slit a

Solution

As the single slit of width a has a bright central maximum of width:

ω=2λL/a

a=2λL/ω

Substitute the given values

So

a=\frac{2*680*10^{-9}m*5.5m}{0.079m} \\a=9.47*10^{-5}m\\or\\a=0.0947mm
