It really depends on how far or close the planet is from the sun

Answer:

The length of its year.

Explanation:

When Earth completes a full rotation, a year has completed. So, the same can be the same for other orbiting planet. The moon for example takes 29.5 days to revolve around the Earth, so one moon year is 29.5 Earth days.

Answer:

Microwave: Radiation

Water: Conduction, convection & radiation.

Explanation:

When we heat a food using microwave then the water content of the food is only heated by the microwave.

Microwaves make the molecules of water vibrate frequently with a frequency closer to the frequency of microwaves and this increases the kinetic energy of the molecules which produces heat in the water molecules this heat then propagates to the whole food by conduction and convection, but the heat enters the food only via radiation.

Now when the food item is kept into warm water then the molecules closer to the food heat the food by conduction through direct energy transfer by lattice vibrations and when they become cooler than the mass of water all around then due to density difference they settle down and their place is occupied by warmer molecules around in the fluid leading to convection.

Radiation of energy from a mass occurs continuously irrespective of the medium present there. So the heat of water also enters the food by radiation of energy from the water molecules.

Falculate the speed of a wave with frequency of 10KHz and wave length of 2m

aleksklad [387]

Answer:20000m/s

Explanation:

Frequency=10khz

Frequency=10x1000

Frequency=10000hz

Wavelength=2m

Speed= frequency x wavelength

Speed=10000 x 2

Speed=20000

speed=20000m/s

Anastaziya [24]

Answer:

F = 8840.7 N

Explanation:

The parameters given are:

Length L = 3 metres

Extension e = 3 × 3 = 9m

Force constant K = 982.3 Newton per metre

From Hook's law,

Provided the elastic limit is not extended, the extension is directly proportional to the force applied.

That is,

F = Ke

Substitute all the parameters into the formula

F = 982.3 × 9

F = 8840.7 N

What is the equivalent capacitance of the three capacitors in the figure (figure 1)?

vekshin1

The equivalent capacitance of the combination is $\dfrac{1}{C} = \dfrac{1}{C_1}+\dfrac{1}{C_2}$ where C1 and C2 are the capacitance of both capacitors in series.

<h3>What is equivalent capacitor?</h3>

Let the capacitance of both capacitors be C1 and C2. For a series connected capacitors, same charge flows through the capacitors but different voltage flows through them.

Let Q be the amount of charge in each capacitors,

V be the voltage across each capacitors

C be the capacitance of the capacitor.

Using the formula Q = CV where V = Q/C... (1)

For the large capacitor with capacitance of the capacitor C1,

$Q = C_1V_1;$
