Answer:
0.00158 A
Explanation:
A = Area of loop = 7.8 cm²
= Final magnetic field = 3.2 T
= Initial magnetic field = 0.5 T
R = Resitance = 
The emf is given by
The current is given by
The resulting induced current in the loop is 0.00158 A
about 1/10th as great by bending your legs
Time extended decreases acceleration value.
solve using Newton's 2nd and Uniform Acceleration Laws. plug in values for descending.
Vf = 0.0 m/s
Vi = 10 m/s
t = 1 s
Acceleration is given by
a = [Vf - Vi] / t
a = [ (0.0 m/s) - (10 m/s) ] / (1 s)
a = [ -10 m/s ] / (1 s)
a = -10 m/s^2
Solve the same thing, but with time 10x, so t = 10 s
a = [ (0.0 m/s) - (10 m/s) ] / (10 s)
a = [ -10 m/s ] / (10 s)
a = -1 m/s^2
Solve for first force and second force, using a mass of 100 kg
F = m * a
F = (100 kg) * (-10 m/s^2)
F = -1,000 N
F = (100 kg) * (-1 m/s^2)
F = -100 N
So divide long-force by short-force
(-100 N) / (-1,000 N) = 0.1 (which is 1/10)
12 cm x 2 cm x 3 cm = 72 cm3
Answer:
Magnetometer
Explanation:
Magnetometer technique is not using by scientists for studying the ocean floor.The scientists currently is using SONAR ( sound navigation and ragging) technique for studying the ocean floor.SONAR is used sound waves sound waves for studying the ocean floor or we can say that SONAR is based on sound propagation.
Therefore answer is Magnetometer
Answer:
(a). Energy is 64,680 J
(b) velocity is 51.43m/s
(c) velocity in mph is 115.0mph
Explanation:
(a).
The potential energy 
of the payload of mass 
is at a vertical distance 
is
.
Therefore, for the payload of mass 
at a vertical distance of 
, the potential energy is
(b).
When the payload reaches the bottom of the shaft, all of its potential energy is converted into its kinetic energy; therefore,
(c).
The velocity in mph is
