Answer:
(a) 112.5 V/m
(b) 0.01494 T
Explanation:
velocity, v = 4.5 km/s = 4500 m/s
magnetic field, B = 2.5 x 10^-2 T
mass, m = 6.64 x 10^-26 kg
charge, q = 1.6 x 10^-19 C = 1.6 x 10^-19 C
(a) The force due to the magnetic field is balanced by the force due to the electric field
q E = B q v
E = B v = 2.5 x 10^-2 x 4500 = 112.5 V/m
(b) radius, r = 12.5 cm
B' = 0.01494 T
Answer:
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. ... When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material. At the center, gravity pulled more and more material in.
Explanation:
True. That is how powerful the sun is. But it will explode in only about 5 billion years.
Hi there!
Recall:
Impulse = Change in momentum
I = Δp = mΔv = m(vf - vi)
Let the direction TOWARDS the floor be POSITIVE, and AWAY be NEGATIVE.
Plug in the givan values:
Δp = 1.5(-10 - 12) = -33 Ns
**OR, the magnitude: |-33| = 33 Ns
Answer:
and unbalanced force
Explanation:
if balanced then the object will exert as much force as you are. its like pushing against a wall. and unblanced force is like pushing against a chair
