Answer:
Dont understand question, sorry!!!
Explanation:
wavelength = l
speed of wave = v
frequency = f
v = lf → f = v/l = 2.42 × 10⁴ ÷ 1.1 = 2.2 × 10⁴ 1/s
T = 1/f = 1/ 2.2 × 10⁴ = 0.45 × 10 -⁴ s
Answer:
=8.0 Watts
Explanation:
Power is a ratio of work done over time. The power in an electric circuit is calculated using the following formula:
P=I²R
P is power, I is current, R is resistance
Therefore, Power= 4²ₓ 0.5Ω
=8.0 Watts
Answer:
Velocity of proton will be equal to 4500 m/sec
Explanation:
We have given that proton moves right angles through a magnetic field
So angle between magnetic field and velocity of proton is
Magnetic field B = 0.025 Tesla
Charge on proton
Magnetic force on the proton is given
Magnetic force on a moving charge particle is equal to
So
v = 4500 m/sec
So velocity of proton will be equal to 4500 m/sec
