Answer:
Gravity creates stars and planets by pulling together the material from which they are made.
Explanation: Thats the only thing i have im stuck on the tga quiz
Acceleration = (final velocity-initial velocity)/time
5 = (v-0)/20
v = 100m/s
Asteroids are located in orbits of other planets such as Mars, and Jupiter. There are belts of asteroids around the solar system "behind mars, and next to Jupiter." They orbit the planets and they also have the "Main Asteroid belt which circles around planets 1-4.
Hope this helps!
Answer:
True statements:
Power is the rate at which work is done.
Power is the rate at which energy is transformed.
The SI unit of power is watt.
A person is limited in the total work he or she can do by the rate at which energy can be transformed.
Explanation:
The above statements are true.
1. Power is defined as the rate at which work is done.
2. Power is the rate at which energy is transformed. Whenever energy changes its form, or moves from one place to another, the rate at which it makes those changes is described as power.
3. The SI Unit of power is watts. If 1 joule of energy is converted by an object in 1 second then its power is called one watt.
So, the statement<em> 'the SI unit of power is the horsepower' is</em> false.
4. A person is limited in the total work he or she can do by the rate at which energy can be transformed i.e, his power. He is not only limited by the total energy required.
So, the statement <em>'A person is limited in the total work he or she can do only by the total energy required'</em> is not completely true.
