The speed of wave is 304.85 m/s.

Answer:

Explanation:

Speed is the measure of rate of motion of any object. So in other words , it can be determined as the product of wavelength and frequency. As wavelength is the measure of distance covered or the distance between two consecutive crests or troughs. And frequency is inversely proportional to the time period of complete cycle.

Thus, speed = Wavelength × Frequency

As here the wavelength is given as 0.0325 m and the frequency is given as 9380 Hz, then

Speed of wave = 0.0325 × 9380 = 304.85 m/s

So the speed of wave is 304.85 m/s.

In the Biomedical and Physical Sciences building at MSU there are 135 steps from the ground floor to the sixth floor. Each step

Kipish [7]

Answer:

W = 16.4 kJ

Explanation:

Given that,

There are 135 steps from the ground floor to the sixth floor.

Each step is 16.6 cm tall.

The mass of a person, m = 73.5 kg

We need to find the work done by the person. We know that,

Work done = Fd

Where

d is the displacement, d = 135 × 0.166 = 22.41

So,

W = 73.5 × 10 × 22.41

= 16471.35 J

W = 16.4 kJ

So, 16.4 kJ is the work done by the person.

Elan Coil [88]

The spring constant is 181.0 N/m

Explanation:

We can solve the problem by applying the law of conservation of energy. In fact, the elastic potential energy initially stored in the compressed spring is completely converted into gravitational potential energy of the dart when the dart is at its maximum height. Therefore, we can write:

$\frac{1}{2}kx^2 = mgh$

where the term on the left represents the elastic potential energy of the spring while the term on the right is the gravitational potential energy of the dart at maximum height, and where

k is the spring constant of the spring

x = 2.08 cm = 0.0208 m is the compression of the spring

m = 12.3 g = 0.00123 kg is the mass of the dart

$g=9.8 m/s^2$ is the acceleration due to gravity

h = 3.25 m is the maximum height of the dart

Solving for k, we find:

$k=\frac{2mgh}{x^2}=\frac{2(0.00123)(9.8)(3.25)}{(0.0208)^2}=181.0 N/m$
