While on a moving elevator during a certain perfod or time, Frank's apparent weight is 620 N. If Frank's mass is 70 kg, what is
MakcuM [25]

Answer:

0.94 m/s^2 downwards

Explanation:

m = 70 kg, m g = 70 x 9.8 = 686 N

R = 620 N

Let the acceleration be a, as the apparent weight decreases so the elevator is moving downwards with an acceleration a.

mg - R = ma

686 - 620 = 70 x a

a = 0.94 m/s^2

A coil is wrapped with 332 turns of wire on the perimeter of a circular frame (of radius 30 cm). Each turn has the same area, eq
almond37 [142]

Answer:

E=84.5V

Explanation:

From the question we are told that:

Number of Turns N=332turns

Radius r= 30cm

Field Change B=56mt-29mt=27mt

Time t=63ms

Generally the equation for Magnetic Field is mathematically given by

 \frac{dB}{dt}=\frac{27*10^{-3}}{29*10^{-3}}

 \frac{dB}{dt}=0.9T/s

Generally the Flux at 332 turns is  mathematically given by

 \phi=N*A*B

Generally the equation for Area of coil is mathematically given by

 A=\pi*r^2

 A=\pi*(r*10^{-2})^2

Since

 \phi=332*\pi*(\theta*10^{-2})^2*B

Therefore

 \frac{d \phi}{dt}=332*\pi*(900*10^{-4}*\frac{dB}{dt}

Generally the equation for emf Magnitude is mathematically given by

 E=\frac{d\phi}{dt}

 E=332*\pi*(900*10^{-4}*0.9

 E=84.5V

How does gravity affect space travel?
IceJOKER [234]

Answer: Think of it like this, in space there is no gravity. This makes it very hard to move. This is why spacesuits have mini propellers. And the reason why rockets well... have rockets.
