Answer:

11995200 N/m²

Explanation:

Pressure: The is the ratio of force to the surface area in contact. The S.I unit of pressure is N/m².

Generally pressure in fluid can be expressed as

P = ρgh......................... Equation 1

Where P = maximum pressure on the submarine hull, ρ = Density of ocean, h = depth of ocean, g = acceleration due to gravity.

Given: h = 1200 m, ρ = 1020 kg/m³

Constant: g = 9.8 m/s²

Substitute into equation 1

P = 1200(1020)(9.8)

P = 11995200 N/m²

Hence the maximum pressure on the submarine hull = 11995200 N/m²

mars1129 [50]

Answer:

The net force is 21 N, and the bag will go to the right.

Explanation:

You can find the net force by adding both values of the boy and the girl, and then subtracting four from it. You can also figure out which direction its moving by looking at which side is exerting the most force, which would be the right side.

If a vibrating string is made shorter (i.e., by holding your finger on it), what effect does this have on the frequency of vibra
Temka [501]
The correct answer is "3. Both increase"

In fact, the frequency of a vibrating string is given by
f= \frac{1}{2L}  \sqrt{ \frac{T}{\mu} }
where L is the length of hte string, T the tension and \mu the linear mass density. 
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.

Bond [772]
<span>Wavelength = (speed) / (frequency)
Speed of EM radiation = 3 x 10⁸ m/s

Frequency (3 × 10¹⁹ Hz)  ===>  wavelength  =  0.01 nanometer

Frequency (3 × 10¹⁶ Hz)  ===>  wavelength  =  10 nanometers</span>

This is the region of X-rays.
