Answer: Convection
Explantion: Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection
I believe this would be an example of Mary's velocity. We have her speed and direction which is all you need to find velocity.
Answer:
Toward us faster than the second object
Explanation:
It take <u>approximately 29</u><u>.</u><u>5 </u><u>days</u> for moon to do its entire set of phases.
<h3>Explanation</h3>
The Moon is the only natural satellite of the Earth which undergoes three motions, that is :
- Rotating on its own axis
- Evolving around the Earth
- Together with the Earth evolving around the sun as the center of the solar system
With that, the moon has two periods of revolution, namely:
- Sidereal revolution, which is the original revolution of the Moon. This sidereal revolution is really the time it takes the Moon to orbit the Earth. The sidereal revolution of the moon has a time span of <u>27.3 days</u> or more accurate is approximately 27 days, 7.72 hours.
- Synodic revolution, namely the revolution of the Moon as seen from Earth as a series of moon phases (from the new moon phase, to the next new moon phase). The synodic revolution is slower, because the Moon needs to catch up with the Earth rotating in the same direction as the Moon. The synodic revolution of the moon has a time span of 29.5 days or to be more accurate approx 29 days, 12.734 hours.
Answer:
The least amount of time in which the fisherman can raise the fish to the dock without losing it is t= 2 seconds.
Explanation:
m= 5 kg
h= 2m
Fmax= 54 N
g= 9.8 m/s²
W= m * g
W= 49 N
F= Fmax - W
F= 5 N
F=m*a
a= F/m
a= 1 m/s²
h= a * t²/2
t= √(2*h/a)
t= 2 seconds
