100 watts = 100 joules per second
22 watts = 22 joules per second
Saving = 78 joules per second
1 hour = 3,600 seconds
24 hours = 86,400 seconds
(78 joules/sec) x (86,400 sec) = 6,739,200 joules
Answer:
the branch of mechanics concerned with the interaction of electric currents with magnetic fields or with other electric currents.
Explanation:
Probably C? I’m not exactly sure but from my knowledge, it maybe C
<span>A
quarterback ... runs
backward for 15 meters,
=> displacement vector = -15 j
he ... runs sideways parallel to the line of
scrimmage for 12 meters.
=> displacement vector = 12 i
he throws the ball 50 meters
perpendicular to the line of scrimmage
=> displacement vector = 50j
where it is caught by the
receiver.
=> net displacement = -15j + 12i + 50j = 12i + 35j
How far is the football from its original position?
distance ^2 = (12m)^2 + (35m)^2 = 1,369 m^2
=> distance = √ (1,369m^2) = 37 m^2
Answer: 37 m^2
