Explanation:
formula for energy is k. e = ½mv²
m= 9
v= 75
k. e = ½×9×75 =337•5
W = 25 J
Explanation:
Work done on an object is defined as
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
-- make sure you have enough money;
-- make sure you arranged for someone to feed the dog and the goldfish;
-- make sure you turned off the faucets and the stove burners.
Answer:
"Speed" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes.
"Velocity" is the rate at which distance is being covered .... the ratio
of distance covered to the time it takes ... AND the direction in which
it is covered. 'Speed' with the direction of the motion.
