Answer:
23932242.5 Pa
Explanation:
= Atmospheric pressure =
= Pressure of seawater
= Density of sea water =
h = Depth of shipwreck =
g = Acceleration due to gravity = 9.81 m/s²
The absolute pressure is given by
The absolute pressure at the depth of the shipwreck is 23932242.5 Pa
Rotation. The Earth rotates around the sun on it’s axis. Depending how far north or south you live, and the angle of the sun at different times of year gives you the amount of daylight or darkness you will receive. So the length of day or night depends on how much the sun is able to reach the spot on a round object such as the planet Earth.
Answer
Given,
Length of the wire,L = 31 cm = 0.31 m
mass of the wire, m = 9 g = 0.009 Kg
Current in the wire,I = 7 A
Magnetic field strength, B= ?
Equating magnetic force to the weight of the wire.
B = 0.0407 T
For Force to be upward magnetic field direction should be outward of the plane of paper.
