True. That is how powerful the sun is. But it will explode in only about 5 billion years.
Answer:
1 solar masses
Explanation:
-Sirius has to maintain equilibrium with it's companion.
-Let x be the mass of Sirius and y be the mass of it's companion.
-From the question, we know that Sirius is 2.35 times heavier than it's companion:

Hence, the mass of it's companion is 1 solar masses
Electric energy is transformed into mechanical energy of the dryer's engine and heat of the dryer's heater unit.
Answer:

Explanation:
Mechanical Energy=Potential Energy+ kinetic Energy

To calculate Kinetic Energy:-

To calculate Potential Energy:-

therefore,

The skydiver's total mechanical energy is 459365J
Answer:
9.66 x 10^-6 m
Explanation:
Use the Wein's displacement law

Where, b is the Wein's constant
b = 2.898 x 10^-3 meter-kelvin
So, λm x 300 = 2.898 x 10^-3
λm = 9.66 x 10^-6 m
