Convection is the transfer of heat from one place to another along with the motion of the object's particles. Water is a poor conductor. However, when the bottom water is heated, it turns out that the top water is also hot. This means that there is another way of transferring heat to the water, namely convection.

The planet Mercury takes 0.24 sidereal years to go around the sun. What is the distance from the center of Mercury to the center

lyudmila [28]

Answer:

5.77×10¹⁰ m

Explanation:

From the question,

Applying

Kepler's third law

P² = d³...................... Equation 1

Where P = Planet's period, d = distance between the center of the planet and the sun.

make d the subject of the formula n equation 1

d = $\sqrt[3]{P^{2} }$ .................. Equation 2

Given: P = 0.24 sidereal.

Substitute the value of P into equation 2

d = $\sqrt[3]{0.24^{2} }$

d = 0.386 Au

d = 0.386×1.496×10¹¹

d = 5.77×10¹⁰ m

11. What is the difference between AM radio waves and FM radio waves?

siniylev [52]

Answer:

they amplitude modulation

and they ferequency modulation

Explanation:

The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.

hope it helps
