Here's the tool you need. You can't answer the question without this:
"1 watt"
means
"1 joule of energy, generated, used, or moved, every second".
So 60 watts = 60 joules per second
Total energy generated,
used, or moved = (power) x (time).
580 joules = (60 watts) x (time)
Divide each side
by (60 watts): Time = (580 joules) / (60 joules/sec)
= (9 and 2/3) seconds .
Answer:
A is the answer. Im only 12 and i hope this explanation helps you.
Explanation:
Lenz's Law of Electromagnetic Induction. Faraday's Law tells us that inducing a voltage into a conductor can be done by either passing it through a magnetic field, or by moving the magnetic field past the conductor and that if this conductor is part of a closed circuit, an electric current will flow.
Answer:
v = 54.2 m / s
Explanation:
Let's use energy conservation for this problem.
Starting point Higher
Em₀ = U = m g h
Final point. Lower
= K = ½ m v²
Em₀ = Em_{f}
m g h = ½ m v²
v² = 2gh
v = √ 2gh
Let's calculate
v = √ (2 9.8 150)
v = 54.2 m / s
Answer:
C the baseball began at rest and rolls at a rate of 14.7 m/s after 1.5 seconds
Stress = force / area
= 4.8 x 10³ / 1.2 x 10^-4
= 4 x 10⁷ N /m²
YOUNGS MODULAS = stress / strain
= 4 x 10⁷ / 1.2 x 10^11
= 3.3 x 10^-4
INCREMENT OF LENGTH = longitudinal length x intitial length
= ( 3.3 x 10^-4 ) x 4
= 13.2 x 10^-4 m
= 13.2 mm
