That's true. The only way to stop an object from radiating energy
is to cool it to absolute zero. Since the temperature of space is
roughly 3 degrees above absolute zero, the atoms or molecules
of every object have some kinetic energy, and the object radiates
some heat.
Of course it also absorbs heat at the same time, mostly from the
huge number of stars shining on it.
Answer:
1327 kg
Explanation:
So the net force exerted on the wagon would be the sum of forces from 2 horses subtracted by friction force
This force results in an acceleration of a = 1.3 m/s2. We can use Newton's 2nd law to calculate the mass of the wagon
Answer:
Names of the Equations of Motion
1 The First Equation of Motion is, v=u+at is known as velocity – time relation. 2 The Second Equation of Motion is, s=ut+12at2 is known as position – time relation.
example of a great insulator is a thermos. If you put soup in a thermos, you can open it later and enjoy warm soup on a cold winter day. The thermos insulates the soup, trapping the heat inside. Likewise, if you are playing soccer on a hot August afternoon, your thermos full of ice water stays refreshing and cold.
