D.) White Dwarf
It is the smallest star whose mass is approximately equal or greater than 1.4M
Here, M = mass of the Sun.
Hope this helps!
The correct matches are as follows:
<span>1. Mechanical Energy
</span>This is the energy of motion and position - Kinetic Energy and Potential Energy are included here.
<span>
2. Electrical Energy
</span>This is the type of energy that is given off as a result of electrons (charges!) moving through a conductor.
<span>
3. Light Energy
</span>This is the only form of energy we can see with our eyes!
<span>
4. Thermal Energy
</span>This is heat energy! It can be transferred through conduction, convection, or radiation.
<span>
5. Sound Energy
</span>This is energy that is transmitted through vibrations.
<span>
6. Kinetic Energy
</span>This is the energy that all moving objects have. <span>
7. Potential Energy
</span>This is stored energy, waiting to be used!
The planets have (their) moons. So the answer would be planets.
I would say B
Because technically if your just holding it your not doing anything

Velocity of proton= 4782 m/s
Explanation:
For proton, the centripetal force required for circular motion is provided by the magnetic force,
so Fm= Fc
q v B = m v²/r
m= mass of proton
v= velocity
B =magnetic field=0.05 T
q= charge= 1.6 x 10⁻¹⁹
r= radius = 1 mm =0.001 m
v= q B r/m
V= (1.6 x 10⁻¹⁹)(0.05)(0.001)/(1.673 x 10⁻²⁷)
V= 4782 m/s
