Answer:
Explanation:
Let mass and velocity of proton be m and v .
1/2 m v² = 59 x 10⁶ e V
= 59 x 10⁶ x 1.6 x 10⁻¹⁹ J
= 94.4 x 10⁻¹³ J
mv² = 188.8 x 10⁻¹³ J
v² = 188.8 x 10⁻¹³ / m
= 188.8 x 10⁻¹³ / 1.67262 x 10⁻²⁷
= 112.8768 x 10¹⁴
v = 10.62 x 10⁷ m / s
In circular path of proton , magnetic force equals centripetal force .
m v² / r = B q v , B is magnetic field , q is charge on proton , r is radius of circular path .
188.8 x 10⁻¹³ / 5.8 x 10¹⁰ = B x 1.6 x 10⁻¹⁹ x 10.62 x 10⁷
B = 1.9157 x 10⁻¹¹ T.
Liquid water freezes and becomes solid ice when the molecules lose energy
Answer:
Uniform Circular Motion What is the direction of the force that acts on the clothes in the spin cycle of a washing machine?
Explanation:
The string acts as the centripetal force that pulls the bucket and water into the center and keeps them from following their paths of inertia, giving the illusion that centrifugal force is pulling the water away from the center. ... If you spin the bucket too slowly, the water will fall out and you will get wet.
Answer:
1.The Sun is located at one of the foci of the planets' elliptical orbits.
2.The path of the planets around the Sun is elliptical in shape.
Explanation:
As per Kepler's law of planet motion we know that all planets revolve around the sun in elliptical path in such a way that position of Sun must be at one of the focii of the path
So all planets are in elliptical path always
Position of sun is always at one of the focus
so correct answer will be
1.The Sun is located at one of the foci of the planets' elliptical orbits.
2.The path of the planets around the Sun is elliptical in shape.
