Answer:
Explanation:
Let the velocity of deuteron be v then force on it in magnetic field
Bqv , B is magnetic field and q is charge on deuteron . This force will provide centripetal force for circular path so
mv² / r = Bqv m is mass of deuteron and r is radius of circular path
v = Bqr / m
(.5 x 1.6 x 10⁻¹⁹ x 55.6 x 10⁻² )/ 3.34 x 10⁻²⁷
= 13.31 x 10⁶ m /s
Answer:
Some examples of levers include more than one class, such as a nut cracker, a stapler, nail clippers, ice tongs and tweezers. Other levers, called single class levers include the claw end of a hammer.
Explanation:
Answer : Radius of Earth is 6,340 Km.
Explanation
It is given that,
Tangential velocity of Earth at the equator, v = 465 m/s
Centripetal acceleration at the equation is, 
We know that the relation between centripetal acceleration and tangential velocity is :
..........(1)
Where,
v is tangential velocity
r is the radius
Putting all values in equation (1)


or

The Earth's radius is 6,340 Km. Hence, this is the required solution.
Answer:
0.83x10^-9 T
Direction is towards +z axis.
Explanation:
E = cB
E = magnitude of electrical 0.25 Em
c = speed of light in a vacuum 3x10^8 m/s
Therefore,
B = E/c = 0.25 ÷ 3x10^8
B = 0.83x10^-9 T
Magnetic fueld of a EM wave acts perpendicularly to its electric field, therefore it's direction is towards the +Z axis
