Answer:
D
Explanation:
D it generates pressure by fusing hydrogen.
Current = (voltage) / (resistance)
= (150 volts) / (48,000 ohms)
= 3.125 milliamperes
It can also be called the thermal kinetic energy. The internal energy of a system is the total thermal kinetic energy and thermal potential energy of all its atoms and molecules. The Kinetic Theory of Matter is explains the kinetic energy of particles in an object.
Answer:The Poynting vector SS represents the flow of energy in an EM field. Specifically, if uu is the energy density of the field, the Poynting vector satisfies the continuity equation for it:
∂u∂t+∇⋅S=0
∂u∂t+∇⋅S=0
in vacuum. (This is Poynting's theorem.)
In your particular problem, EE and BB are perpendicular and their cross product is proportional to the product of their amplitudes. Thus
Sz=cμ0B2.
Sz=cμ0B2.
You then have to use your knowledge of BB to work out SS.
Explanation:
Answer:
Final speed after 2 seconds = 34.6 m/s
Explanation:
Given:
Initial speed of coin (u) = 15 m/s
Time taken = 2 seconds
Find:
Final speed after 2 seconds
Computation:
Gravitational acceleration of earth = 9.8 m/s²
Using first equation of motion;
v = u + at
or
v = u + gt
where,
v = final velocity
u = initial velocity
g = Gravitational acceleration
t = time taken
v = 15 + 9.8(2)
v = 15 + 19.6
Final speed after 2 seconds = 34.6 m/s
