Answer:

The force needed to lift the crate is 50 N

Explanation:

P_{1} = \frac{F_{1}}{A_{1}} = \frac{1500N}{25 m^{2} } \\P_{1}= P_{2} \\P_{2} = \frac{F_{2}}{A_{2}}\\A_{2} = 25*\frac{1}{30} \\\frac{1500N}{25 m^{2} } =\frac{F_{2} }{\frac{25}{30}m^{2}  }\\ F_{2}* 25 m^{2} = 1500 N *\frac{25}{30}m^{2}\\ F_{2}= \frac{1250 N*m^{2}}{25 m^{2}}\\ F_{2}= 50 N

A column of soldiers, marching at 114 steps per minute, keep in step with the beat of a drummer at the head of the column. It is
kipiarov [429]

Answer:

length of column is 140.42 m

Explanation:

in 1 min the soldiers travels 114 steps

so to complete 1 step the time taken by the soldiers =

t =  \dfrac{1\ min}{114}

t =  \dfrac{60}{114}  

t = 0.526 s

speed of sound = 343 m/s

length of the column = v × t

                                   = 343 m/s × 0.526 s

                                   = 140.42 m

hence the length of column is 140.42 m

Determine the moment of inertia of a uniform solid sphere of mass M and radius R about an axis that is tangent to the surface of
Inessa05 [86]

Answer:

I = \frac{7}{5}MR^2

Explanation:

For answer this we will use the paralell axis theorem:

I= I_{cm} + Md^2

Where I_{cm} is the moment of inertia of the center of mass, M is the mass of the sphere and d is the distance between the center of mass and the axis for rotate, then:

I = \frac{2}{5}MR^2 +MR^2

I = \frac{7}{5}MR^2

Which accurately describes the behavior of sound and light in the vacuum of space?
Romashka-Z-Leto [24]
<span>
A vacuum doesn't contain a medium. Light, which is an electromagnetic
wave and doesn't require a medium, will travel there. Sound, which is a
mechanical wave and requires a medium, will not travel there.</span>

(You can see the light of the sun and other stars, which travels to us through
space.  Astronauts can't hear the sound of each others' voices when they're
standing together on the moon because there's no medium between them,
so they have to use radio even to go only a few feet.)

Utility companies charge by the kilowatt-hour. The number of kilowatt-hours used equals the number of kilowatts multiplied by th
Dmitry [639]

Answer:

t = 3 minutes

Explanation:

Given that,

Power of fan, P = 50 W

Energy used, E = 1 kWh

We know that,

Energy = Power/time

As, 50 watts = 0.05 kilowatts

So,

t=\dfrac{P}{E}\\\\t=\dfrac{0.05\ kW}{1\ kWh}\\\\t=0.05\ h

or

t = 3 min

So, the required time is equal to 3 minutes.
