Answer:
the mass of body increases when accelerated.
Work is done when a motion resulted from the force being done by an object. The amount of work done is calculated by multiplying the force applied and the distance traveled. It is calculated as follows:
Work = Force x distance = 280 N x 5 m = 1400 J.
Answer:
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth's heat escapes into space, which is electromagnetic radiation. Every object, including the Earth's surface, absorbs and radiates heat electromagnetically

by the sun. The reason why the moon
changes it phases is because Moon orbits around the Earth, and due to this some
areas of the half of the moon will not be lit by the sun.
Answer: The correct answer is : From the period-luminosity relation for Cepheids, he was able to determine the distance to Andromeda and show that it was far outside the Milky Way Galaxy.
Explanation: Hubble's law says that the recession velocity of a galaxy is directly proportional to its distance from us. Hubble measured the distance to the Andromeda galaxy by applying the period-luminosity relationship to Cepheid.
