The reading of the balance if ,
I ) If the elevator is moving with a steady speed = 50 N
II ) If the elevator is moving upwards with acceleration of 0.2 m / s² = 51 N
T = m g + m a
T = Force
m = Mass
g = Acceleration due to gravity
a = Acceleration
m = 5 kg
g = 10 m / s²
I ) If the elevator is moving with a steady speed,
At steady speed, a = 0
T = ( 5 * 10 ) + ( 5 * 0 )
T = 50 N
II ) If the elevator is moving upwards with acceleration of 0.2 m / s²,
a = 0.2 m / s²
T = ( 5 * 10 ) + ( 5 * 0.2 )
T = 50 + 1
T = 51 N
Therefore, the reading of the balance if ,
I ) If the elevator is moving with a steady speed = 50 N
II ) If the elevator is moving upwards with acceleration of 0.2 m / s² = 51 N

With arms outstretched,
Moment of inertia is I = 5.0 kg-m².
Rotational speed is ω = (3 rev/s)*(2π rad/rev) = 6π rad/s
The torque required is
T = Iω = (5.0 kg-m²)*(6π rad/s) = 30π
Assume that the same torque drives the rotational motion at a moment of inertia of 2.0 kg-m².
If u = new rotational speed (rad/s), then
T = 2u = 30π
u = 15π rad/s
= (15π rad/s)*(1 rev/2π rad)
= 7.5 rev/s
Answer: 7.5 revolutions per second.
To find the answer, plot down the factors for every number.
12: 1, 2 ,3 ,4, 6, 12
18: 1, 2, 3, 6, 9, 18
84: 1, 2, 3, 4, 6, 7, 12
If you noticed, the number that was common to the 3 numbers, were 1, 2, 3, and 6
And 6 is the bigger number
So 6 is your GCF
Unlike a longitudinal wave, a transverse wave moves about, perpendicular to the direction of propagation. The particles in a transverse wave do not travel along the direction of propagation, but only oscillate up and down on its equilibrium position. With this, the displacement can be determined by measuring (in the case of electronic waves, using an oscilloscope or spectrum analyzer) and setting the desired units to measure the wave in.
