Answer:
D. The force on the wire is 24 N.
Explanation:
Given;
length of the wire, L = 0.6 m
current in the wire, I = 4 A
magnitude of the magnetic field, B = 10 T
The fore on the wire is calculated as;
F = BILsinθ
where;
θ is the angle of inclination of the wire on magnetic field = 90°
F = (10)(4)(0.6)(sin 90°)
F = 24 N
Therefore, the force on the wire is 24 N.
Answer:
1) 10 Ω of resistance produced a current of 2.5 Ampere.
2) 100 Ω of resistance produced a current of 0.25 Ampere.
Explanation:
Ohm's law is defined as the law which gives us the relationship between voltage and current.
The equation used to represent this law is:
where,
V = voltage of the circuit. The unit for this is Volts.
I = current of the circuit. The unit for this is Amperes
R = resistance of the circuit. The unit for this is Ohms.
1) 10 Ω of resistance produced a current of:
V = 25 Volts
2) 100 Ω of resistance produced a current of:
V = 25 Volts
Answer:
The value is
Explanation:
From the question we are told that
The power output from the sun is
The average wavelength of each photon is
Generally the energy of each photon emitted is mathematically represented as
Here h is the Plank's constant with value
c is the speed of light with value
So
=>
Generally the number of photons emitted by the Sun in a second is mathematically represented as
=>
=>
