If your ref points are each other and not the surrounding environment, at the same speed you would both appear to be stationary
<em>The main cause of twice-daily tides around the world are;</em>
Gravitational pull of the moon
<u>Tides are the rise and fall of water caused by gravitational forces of the moon and sun on the oceans of the earth. </u>
<u>The moons gravity is large enough to actually pull water out of the ocean from space. Just enough to create motion of the tides.</u>
Answer:
At 11.5 m
Explanation:
The power per unit area corresponds to the intensity, which is given by
where
P is the power
is the area irradiated at a distance r from the source (it corresponds to the surface area of a sphere of radius r)
Here we want the intensity of the two light bulbs to be the same, so
where we have
P1 = 100 W is the power of the first light bulb
P2 = 75 W is the power of the second light bulb
r2 = 10 m is the distance from the second light bulb
Solving for r1, we find
Energy is the ablity to dow work.
Power is the time rate at which work is done.
independent variable often along x axis, dependent along y axis.
You can set the independent value, from which the dependent follows.
Please help me with the unit assessment i have no idea any of the answers
