Answer:
Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.
Explanation:
It is given that total distance is 3.65 m and times is 33.1 s. Therefore, calculate the average speed as follows.
Average speed =
=
= 0.11 m/s
Also, we know that
Average velocity =
Where, displacement means that how far final point is from the initial point, here, that is 0.0463 m.
Hence, calculate the average velocity as follows.
Average velocity =
= 0.0014 m/s
Thus, we can conclude that gnat's average speed is 0.11 m/s and magnitude of the gnat's average velocity is 0.0014 m/s.
Answer:16 Newton’s
Explanation:The equation for finding momentum is momentum= mass x velocity,so
2.0x8.0=16 Newton’s
-- The net effective resistance of three 1200-ohm resistors in
parallel is (1200/3) = 400 ohms. That's what the battery sees.
-- Power = (voltage)² / (resistance)
= (12²) / (400)
= 144 / 400
= 0.36 watt .
There's no such thing as "power in the circuit".
0.36 watt is the power dissipated by the resistors.
It's the rate at which the battery must supply energy,
and the rate at which the resistors blow it off in the form
of heat, for as long as the battery lasts.
Answer:
6 m/s
Explanation:
momentum= mass times velocity
120 = 20v
v = 120/20
