A spherical submersible 1.84 m in radius, armed with multiple cameras, descends under water in a region of the Atlantic Ocean kn

own for shipwrecks and finds its first shipwreck at a depth of 2.37 ✕ 103 m. Seawater has density 1.025 ✕ 103 kg/m3, and the air pressure at the ocean's surface is 1.013 ✕ 105 Pa. What is the absolute pressure at the depth of the shipwreck?

Answer:

23932242.5 Pa

Explanation:

P_a = Atmospheric pressure = 1.013\times 10^5\ Pa

P_w = Pressure of seawater

\rho = Density of sea water = 1.025\times 10^3\ kg/m^3

h = Depth of shipwreck = 2.37\times 10^3\ m

g = Acceleration due to gravity = 9.81 m/s²

The absolute pressure is given by

P_{ab}=P_a+P_w\\\Rightarrow P_{ab}=1.013\times 10^5+1.025\times 10^3\times 9.81\times 2.37\times 10^3\\\Rightarrow P_{ab}=23932242.5\ Pa

The absolute pressure at the depth of the shipwreck is 23932242.5 Pa

If a vehicle accelerating at 2.7 m/s2what is it's velocity at 20 meters 12.63m/s,1.03m/s,10.39m/s,6.39m/s
netineya [11]

Answer:

The final velocity of the vehicle is 10.39 m/s.

Explanation:

Given;

acceleration of the vehicle, a = 2.7 m/s²

distance moved by the vehicle, d = 20 m

The final velocity of the vehicle is calculated using the following kinematic equation;

v² = u² + 2ah

v² = 0 + 2 x 2.7 x 20

v² = 108

v = √108

v = 10.39 m/s

Therefore, the final velocity of the vehicle is 10.39 m/s.

Why is it important for engineers to design bumper cars safely
rosijanka [135]

Answer:

Cars have bumpers designed to protect the body of the car from minor damage during low-speed collisions. ... They will use the engineering design process to design and build bumpers to protect the main parts of their car from damage, and use their knowledge of Newton's third law to explain what they observe.
