What is the answer please help her
Answer:
It can be shown that the potential energy of an object at the surface of the planet would be -G M / R if the potential at infinity is chosen to be zero.
Kinetic energy of G M / R would be required for the escape speed of such an object. The total energy in all such cases is zero.
This can easily be seen by considering the speed of an object falling from infinity towards the planet - the total energy will remain zero if it was zero when the object started to fall.
Explanation:
The question is sound. The frequency and wavelength are given so you can solve for wave's velocity. It's just a matter of changing the notation.
The temporarily be the output of a 100-W light bulb is 148 watt.
To find the answer, we need to know about the resistance of the bulb.
<h3>What's the mathematical expression of resistance of the bulb in term of power and voltage?</h3>
- Mathematically, power= voltage²/resistance
- So, resistance= voltage²/power
<h3>What's the resistance of the bulb, if 115 volt is applied to 100 watt bulb?</h3>
Resistance= 115²/100= 132.25 Ohm
<h3>What's the power of the bulb, if 140 volt is applied to it?</h3>
Power= voltage²/resistance
= 140²/132.25
= 148watt
Thus, we can conclude that the temporary output of the bulb is 148 watt.
