Answer:
Explanation:
As temperature is constant , we shall apply Boyle's law
P₁V₁ = P₂V₂
P₁ = pressure at depth of 10 m
= P + hdg , h = 10 , d = 10³ , g = 10
P is atmospheric pressure which is 10⁵ Pa
P₁ = 10⁵ + 10 x 10³ x 10
= 2 x 10⁵
applying the formula
2 x 10⁵ x 6 = 10⁵ x v
v = 2 x 6 = 12 L
volume will be doubled at the surface .
B )
warming of air at the surface will increase the volume of air in her lungs so so she will need more lung capacity .
C )
The rms value of a gas depends upon the temperature of the gas . As temperature of the gas is constant , the rms value of the gas particles will remain constant when she goes to the surface .
Answer:
M= -10/4
M = -5/2
-5/4 + m = -15/4
Explanation:
3/4 + m = -7/4
Subtract 3/4 from both sides
3/4 + m - 3/4 = -7/4 - 3/4
m = (-7-3) / 4
m = -10/4
m = -5/2
Check the options
11/4 + m = -1/4
m = -1/4 - 11/4
m = (-1-11) /4
m = -12/4
m = -3
-5/4 + m = -15/4
m = -15/4 + 5/4
m = (-15+5) /4
m = -10/4
m = -5/2
Answer:
how you can convert electrical energy to mechanical energy
Explanation:
In the Electric Motor lab, what did you attempt to demonstrate with the electric motor?
In the Electric Motor lab, the experiment usually demonstrate energy conversion process, from electrical energy to mechanical energy. This mechanical energy can also be converted back to electrical energy using a generator.
Therefore, what you attempted to demonstrate with the electric motor, is how you can convert electrical energy to mechanical energy
Tension in the rope due to applied force will be given as
angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done
now we can plug in all values above
So here work done to pull is given by 691.8 J
Answer:
The sun's gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun's gravitational pull, all the planets in our solar system orbit around it.
