the deepest point in the sea is 100m below sea level .what arr the water pressure at this depth and the total pressure due to wa
fomenos

The water pressure at this depth and the total pressure due to water and atmosphere are  10.3 x 10⁵ Pa and 11.31× 10⁵ Pa.

<h3>What is pressure?</h3>

The pressure is the amount of force applied per unit area.

Atmospheric pressure, Patm =1.01×10⁵ Pa

Density of water, ρ=1030 kg/m³

Depth, h=100 m

Pressure =ρgh

P = 1030×10×100

P = 10.3 x 10⁵ Pa.

Total pressure, P=Po +ρgh

P=1.01×10⁵ + 1030×10×100

P=11.31× 10⁵ Pa

Hence, total pressure is 11.31× 10⁵ Pa.

A mass m = 550 g is hung from a spring with spring constant k = 2.8 N/m and set into oscillation at time t = 0. A second, identi
riadik2000 [5.3K]

Answer:

The second system must be set in motion t=0.70s seconds later

Explanation:

The oscillation time, T, for a mass, m, attached to spring with Hooke's constant, k, is:

T=2\pi\sqrt(\frac{m}{k} )

One oscillation takes T secondes, and that is equivalent to a 2π phase. Then, a difference phase of π/2=2π/4, is equivalent to a time t=T/4.

If the phase difference π/2 of the second system relative to the first oscillator. The second system must be set in motion t=\frac{\pi}{2}\sqrt(\frac{m}{k})=\frac{\pi}{2}\sqrt(\frac{0.55}{2.8}= 0.70s) seconds later

Anyone know 1-5? Will give brainliest
baherus [9]

Answer:

1. 200 metres West

2. Dividing distance by time

3. Speed was unchanged

4. 1800 metres

5. 15 seconds

Explanation:

Running 500 metres West puts you 500 Metres west from the start. Then running 300 metres east puts you 200metres from where you started.

Since displacement is the distance you are from your original position 200 Metres West is the answer

2. Distance = Speed x Time

Rearrange that to get Speed = Distance / Time

3. Acceleration is when the rate of increase or decrease of speed or the direction is changing. When the speed or sirection dont change acceleration is 0

4. Distance = Speed x Time

60 x 30 = 1800 metres

5. Time = Distance / Speed

300 / 20 = 15 seconds
