4 0

Answer:

404K

Explanation:

Data given, Kinetic Energy.K.E=8.37*10^-21J

Note: as the temperature of a is increase, the rate of random movement will increase, hence leading to more collision per unit time. Hence we can say that the relationship between the kinetic energy and the temperature is a direct variation.

This relationship can be expressed as

K.E=\frac{3}{2}KT

where K is a constant of value 1.38*10^-23

Hence if we substitute the values, we arrive at

T=\frac{2/3(8.37*10^{-21})}{1.38*10^-23}\\ T=404K

converting to degree we have 131^{0}C

How much gravitational potential energy does an object have if it is located 20 m above the point that we define as O height and
raketka [301]

Answer:

Explanation:

PE = mgh where m is the mass in kg, g is the pull of gravity which is 9.8, and h is the height of the object above the point to which it could possibly fall, measured in meters. Plugging in:

PE = 10(9.8)(20) so

PE = 1960 J

This should be rounded to 1 sig fig according to the rules of sig fig and your numbers here, but I imagine you're not following them all that much. It should be 2000 J

A railroad car containing an angry bull is standing onthe
nata0808 [166]

Answer:

v_{f} = - M / m v

Explanation:

We must define a system formed by the wagon and the torro, in this case the forces of the movement are internal, so the moment is preserved, write the moment in two moments

Initial. Before the bull's movement, in this case the two are still

             p₀ = 0

Final. The bull is moving

            p_{f}= M v + m v_{f}

             p₀ = p_{f}

              0 = M v + mv_{f}

We cleared the train speed

            v_{f} = - M / m v

The negative sign indicates that the train moves in the opposite direction of the bull

Extrusive Igneous rock has ___________ grain size.<br> I need help on this one
MrRissso [65]

Explanation:

Extrusive rocks may have a few grains that are large enough to see, but most of them will be too small to see individual minerals. ... The individual mineral grains are almost too small to see. Some extrusive rocks cool so quickly that they do not form any grains. Instead, they form a natural glass.
