Length L = 25 cm = 0.25 m, B = 600 G = 0.06 T ( 1G = 0.0001 T)
emf= 10 V
Solution:
emf = vBL
v= emf / BL
5 = emf/ (0.25 T× 0.25 m)
emf = 0.3125 v
Magnetic field
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

Answer:
I don't know if this is right or not but I think its Potential Energy
Explanation:
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.
Answer:
90 m
Explanation:
Acceleration, 
where v and u are final and initial velocities respectively, t is the time taken
Substituting 
for a, 4 m/s for u and 10 s for t then
1*10=v-4
v=14 m/s
From kinematic equations
Making s the subject then
Answer:
Explanation:
By conservation of the linear momentum:
m1*V1 = (m1+m2)*V2
Solving for V2:
The kinetic energies are:
Simplifying:
The ratio will be:
