If you ride an elevator moving forward with a constant speed, is your apparent weight same,greater than or less than your weight?

Answers

Answer 1

Answer: If the elevator's speed is constant (in ANY direction) and you can't see out of it, then there's NO measurement you can make inside that will tell you that it's moving. Any weight you measure is normal.

If a wave has a wavelength of 9 meters and a period of 0.006, what is the velocity of the wave?A. 1,285 m/s

B. 1,200 m/s
C. 1,800 m/s
D. 1,500 m/s

Answers

Answer

D. 1,500 m/s

Explanation

the wave equation states that,

V = λf

Where V ⇒ Velocity

λ ⇒ wavelength

f ⇒ Frequency

F = 1/T

Where T ⇒ period

F = 1/0.006

= 166.667

∴ V = 9 × 166.667

= 1,500 m/s

D.1500m/s Speed= Distance/Time : .You simply divide 9metres (distance) by 0.006 (time)

A magnetic field is perpendicular to the plane of a single-turn circular coil. The magnitude of the field is changing, so that an emf of 0.43 V and a current of 3.1 A are induced in the coil. The wire is then re-formed into a single-turn square coil, which is used in the same magnetic field (again perpendicular to the plane of the coil and with a magnitude changing at the same rate). What (a) emf and (b) current are induced in the square coil

Answers

Answer:

2.62A

Explanation:

Given

V = 0.43 V

I = 3.1 A

Then, V = IR, R = V/I

R = 0.43/3.1

R = 0.14 Ω

The induced emf = dB/dt * A

So that, dB/dt = emf/A

Since dB/dt is constant then Emf/A(circle) = Emf/A square

So Emf (square)/Emf (circle) = A square / A circle

A circle = πr². The perimeter of the square is 2πr which also is the circumference of the square.

Since the perimeter is 2πr, then each side would be πr/2. Thus, the area of the square would be, (πr/2)² = π²r²/4

So A square/Acircle = (π²r²/4) / πr² = π/4 = 0.79

this means that, emf square = emf circle * 0.79

emf square = 0.43*0.79 = 0.34V

I = V/R

I = 0.34/0.13

I = 2.62A

What equation can be used to calculate the time of impact when you have the impulse and force applied to an object

A car speeds up from rest to +16 m/ s in 4s. calculate the acceleration

Answers

The magnitude of acceleration is (change in speed) / (time for the change).

Change in speed = (speed at the end) - (speed at the beginning) =

(16 m/s) - (0) = 16 m/s .

Time for the change = 4 s .

Magnitude of acceleration = (16 m/s) / (4 s) = 4 m/s per sec = 4 m/s² .

16 m/s - 0 m/s divided by 4s
= 16 m/s divided by 4s
= 4 m/s
The acceleration is 4 m/s squared

A particle is being accelerated through space by a 10 N force. Suddenly the particle encounters a second of 10 N force in the opposite direction. The particle with both forces acting?

Answers

Answer:

The particle will be rendered still

Explanation:

The particle will be rendered still because of the Newton’s 1st law of motion states that a body will continue to move on forever until contacted by an equal and opposite force. The same case has been produced here and it is justifying the law. If the Force has another direction and magnitude than 10 N then the body will continue to move on in the direction of the greater force.
