Answer:
Scientists who study the Sun usually divide it up into three main regions: the Sun's interior, the solar atmosphere, and the visible "surface" of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun's interior: the core, the radiative zone, and the convective zone.
Explanation:
Hopefully this helps :)
-- "constant velocity" ===> acceleration is 0 .
-- acceleration=0 ===> forces are balanced
-- balanced forces ===> (friction) + (force you exert) = 0
(friction) = -(force you exert)
They have equal magnitude and opposite direction.
-- Before Adrian left the airplane, his gravitational potential energy was
(mass) x (gravity) x (height) = (80kg) x (9.81m/s²) x (1,000m) = 784,800 joules
-- When he reached the ground, his kinetic energy was
(1/2) x (mass) x (speed)² = (40kg) x (5m/s)² = 1,000 joules
-- Between the airplane and the ground, the Adrian lost
(784,800 joules) - (1,000 joules) = 783,800 joules
Where did all that energy go ?
Energy never just disappears. If it's missing, it had to go somewhere.
The Adrian used 783,800 joules of energy to push air our of his way
so that he could continue his parachute jump, and reach the ground
in time to be home for dinner.
Answer:
Magnetic field will be equal to 
Explanation:
We have given velocity of proton 
Magnetic force experienced by proton 
Charge on proton 
Angle between field and velocity 
Force in magnetic field is equal to 
So 
So magnetic field will be equal to
