Answer: B. Heat moves from the stove to the ice cube through conduction.

Explanation:

There are three modes of heat transfer- conduction, convection and radiation.

When two objects which are not in thermal equilibrium come in contact, heat transfer takes place via conduction. The heat transfers from hotter object to the cooler one.

In convection, there is bulk movement of fluid which transfers heat from heat source to the the cooler region of the fluid.

Heat radiation can travel through vacuum from the source of heat.

In the given situation, ice cube is placed on a heat stove. There is a direct contact between the two objects. Heat would transfer from hot stove to cube till the two are in thermal equilibrium.

The moon is smaller and more dense than the Earth, and has less extreme temperature changes.
Lerok [7]
<span>The moon is smaller and more dense than the Earth, and has less extreme temperature changes. The statement presented is True. In terms of temperature, since there is no atmosphere on the moon, then it has less extreme temperature changes. The moon can reach 253 Fahrenheit in the day and -387 Fahrenheit at night.</span>

If an atomic nucleus were the size of a dime how far away might one of its electrons be?
mihalych1998 [28]
The radius of a nucleus of hydrogen is approximately r_{n1}=1\cdot 10^{-15}m, while we can use the Borh radius as the distance of an electron from the nucleus in a hydrogen atom: r_{e1}=5.3 \cdot 10^{-11}m

The radius of a dime is approximately r_{n2} = 9\cdot 10^{-3}m: if we assume that the radius of the nucleus is exactly this value, then we  can find how far is the electron by using the proportion
r_{n1}:r_{e1}=r_{n2}:r_{e2}
from which we find
r_{e2}= \frac{r_{e1} r_{n2}}{r_{n1}}= \frac{(5.3 \cdot 10^{-11}m)(9\cdot 10^{-3}m)}{1 \cdot 10^{-15}m}=477 m

So, if the nucleus had the size of a dime, we would find the electron approximately 500 meters away.

nordsb [41]

Answer:

W=3456 N

Explanation:

Force 1 F_1=3456

Force 2 F_2=2333N

Acceleration at stage 2 a_2=0.39

Generally the weight of the Craft W is given as

W= upward force(thrust)

Therefore

W=3456 N
