Answer
Given,
Magnetic field, B = 0.245 T
KE of the electron = 2.90 x 10⁻¹⁹ J
Speed of electron = ?



v = 7.97 x 10⁵ m/s
radius of the circular path
so,



r = 1.85 x 10⁻⁵ m
Answer:0.6kw
Explanation:
Power=force×velocity
Power=20×30=600w
In kw it's going to be 600/1000=0.6kw
The amount of work done will increase
because work done = distance* force
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Answer:
By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star.
Explanation:
have a great day ahead ♥️
