If the mass of a statellite is doubled while the radius of its orbit remains constant then the speed of the satellite is increased by how much?

The velocity at which the satellite was launched would have to be increased in order for it to maintain the same orbit. So the speed would be increased.

When the speed of body is doubled kinetic energy becomes?
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.

When you double the force acting on an object and keep the mass of the cart constant the acceleration is?
Doubled.
What is the effect on the orbital velocity of the sattelite if its orbital radius is doubled?
You can calculate this with Kepler's Third Law. "The square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit." This is valid for other orbiting objects; in this case you can replace "planet" with "satellite". Just assume, for simplicity, that the satellite orbits Earth in a circular orbit - in this case, the "semi-major axis" is equal to the distance from Earth's center. For your calculations, remember also that if the radius is doubled, the total distance the satellite travels is also doubled.
What happens to the current when the voltage is doubled and the resistance is constant?
I = E/R If resistance is constant, then current is directly proportional to voltage. Double the voltage ===> the current will also double.
How does the mass change when the volume is increased two times?
When volume is increased two times, mass is also doubled. This is because density of a particular material always remains constant, (d=m/v), so to keep density constant, volume increase is balanced by mass increase.
By how much is loudness increased if the intensity is increased 10 times?
Doubled.
Why if a gas is present at 27 Celsius its volume becomes doubled when temperature increases to 327 Celsius under constant pressure?
pV = nRT we can firstly assume that n (number of moles) and R (gas constant) do not change and as pressure is also kept constant, the temperature must be proportional to the volume. Thus if temperature is increased from 27C (300K) to 327C (600K) and is doubled, the volume must also double.
When the contact area is doubled keeping the force acting on the body constant the pressure?
when the contact area is doubled keeping the force constant on the boy, there will be less impact on the body .
What happened to tariffs during McKinleys presidency?

What is the expression for four increased a number then doubled?
2x+4
If the resistance in a circuit is doubled while the voltage remains the constant the current is?
It is halved. coz voltage=current * resistance
When the speed of body is doubled kinetic energy becomes?
If speed/velocity is doubled and mass remains constant, then kinetic energy becomes quadrupled.
If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
