If the temperature does not change but the mass of the object increases the thermal energy in the object decreases

Answer:

Explanation:

Yes, when we heat an object its mass increases. The complete equation is

E2=(pc)2+(mc2)2

And from this equation if a system has zero momentum (p=0), then it has energy E=mc2

When you heat an object the molecules or atoms begin to vibrate, rotate with more kinetic energy. But this doesnt increase the momentum of the system (the object is a system of many particles). Though the kinetic energy of the particles that make the system increases, the system is at rest (when you heat the object the object doesn't start moving). Hence, from the equation I wrote above the energy you provide get added as mass of object.

How could you demomstrate a complete and incomplete loop in an electrical circut

shutvik [7]

Answer:

A complete circuit is a complete loop with electricity flowing the way it's supposed to flow: from the battery, to the component, and back to the battery again. An open circuit is an incomplete loop, where the loop is broken at a particular point and electricity can't flow at all

Explanation:

So, you can show one with how the electricity flows right through and then how the loop is broken so the electricity wont really flow.

A satellite in geostationary orbit is used to transmit data via electromagnetic radiation. The satellite is at a height of 35,00

Nutka1998 [239]

Answer:

$6.99535\times 10^{-6}\ V/m$

Explanation:

P = Power Output = 1000 W

r = Radius = 35000000 m

$\epsilon_0$ = Permittivity of free space = $8.85\times 10^{-12}\ F/m$

c = Speed of light = $3\times 10^8\ m/s$

Intensity of Electric radiation is given by

$I=\dfrac{P}{A}\\\Rightarrow I=\dfrac{P}{4\pi r^2}\\\Rightarrow I=\dfrac{1000}{4\pi\times 35000000^2}\ W/m^2$

Intensity of Electric radiation is given by

$I=\dfrac{1}{2}c\epsilon_0E_0\\\Rightarrow E_0=\sqrt{\dfrac{2I}{c\epsilon_0}}\\\Rightarrow E_0=\sqrt{\dfrac{2\times \dfrac{1000}{4\pi\times 35000000^2}}{3\times 10^8\times 8.85\times 10^{-12}}}\\\Rightarrow E_0=6.99535\times 10^{-6}\ V/m$

The amplitude of the electric field vector is $6.99535\times 10^{-6}\ V/m$

When a boy jumps into a pool

melomori [17]

<u>Answer:</u>

energy only

<u>Explanation:</u>

Water waves transfer energy via oscillations of the water molecules, but the the water molecules themselves do not move along the wave.

This is why when the boy jumps into the water, his kinetic energy is transferred by the water molecules across the pool, but neither the boy nor the water particles move along with the wave.
