scientific laws and theories are proven by experimental data and large bodies of evidence.
Answer:
7174.09 N
Explanation:
Area = 7 ft x 4 x ft = 28 ft^2 = 2.60129 m^2
Pressure = 0.4 psi = 2757.9 Pa
Force = Pressure x Area
Force = 2757.9 x 2.60129 = 7174.09 N
Answer:
L = 1.023 H
Explanation:
given,
radius of the cylindrical solenoid = r = 0.6 m
Number of turns = N = 600
Length = l = 0.5 m
Current in the cylindrical solenoid = 15 A
Inductance in the coil = ?
using formula
L = 1.023 H
the inductance L of the coil is = 1.023 H
Answer:19.997m/s
Explanation:
Velocity=√(centripetal acceleration×radius)
Velocity=√(13.33×30)
Velocity=√(399.9)
Velocity=19.997
Answer:150Nm
Explanation:
Force=50.0N distance=3.00m
Work=force x distance
Work=50 x 3
Work=150Nm
