Answer:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Explanation:
Answer:
speed and temperature
Explanation:
Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier weight the force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object's weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.
Answer:
no. the moon has less of a gravitational pull. therefore it would weigh less than 40n.

Answer:
Explanation:
Given the Kepler's third law
p² = a³
Given that,
Period of earth
P(earth) = 1 year
Distance of earth from sun
a(earth) = 1 A.U
An asteriod that is rotating round the sun is at a distance of 2A.U for the sun
a(asteroid) = 2 A.U
So, we want to calculate period of astronaut I.e. p(asteroid)
Using the Keplers law
p²/a³ = constant
p(earth)²/a(earth)³ = p(asteriod)²/a(asteroid)³
So, p(e)²/a(e)³ = p(a)²/a(a)³
1²/1³ = p(a)²/2³
1 = p(a)/8
p(a) = 8 years
Then, the asteroid will take 8years to round the sun
