What is the relationship between amplitude and frequency of a wave?.
kondaur [170]

Answer:

The relationship between the wave's amplitude and frequency is such that it is inversely proportional to the frequency. The amplitude decreases as the frequency increases. The amplitude increases as the frequency decreases. The higher the energy of a wave, the higher the amplitude. The lower the energy, the lower the amplitude. Energy has no effect on wavelength, speed, or frequency, only the amplitude.

Suppose the line on a distance-versus-time graph and the line on a speed-versus-time graph are both slanted straight lines going
lesya [120]
No, because the distance-time would show a constant velocity but the velocity-time graph shows an increasing velocity.

What is the force required to move a block of mass 150 pound by a distance of 5ft in 8 seconds?
Nadusha1986 [10]

Force required to move a block is 1.615 N

Given:

mass of block = m = 150 pounds = 68 kg

distance = d = 5 ft = 1.52 metres

time = t = 8 sec

To Find:

force required to move the block

Solution: Force is defined as product of mass and acceleration and it's unit is N or Newton.

Velocity = displacement/ time = 1.52 / 8 = 0.19 m/s

Acceleration = velocity/time = 0.19/8 =

0.023 m/s^2

Force = mass x acceleration = 68x0.023 = 1.615 N

Hence, force required to move the block is 1.615 N

The highest occupiable floor of any building is in the Sears Tower in Chicago. The elevators of the central tower of the buildin
irina1246 [14]

Answer:

9727160J

Explanation:

Given parameters:

Height of elevator rise  = 436m

Force exerted  = 22310N

Unknown:

Work done by the elevator lifting mechanism = ?

Solution:

The work done by a body is the force applied to move a body in a specific direction;

          Work done  = force x distance moved

In this case, the force and distance moved is provided already;

        Work done  = 22310 x 436  = 9727160J
