Answer:
42 Hz
Explanation:
Given,
Speed ( v ) = 210 m/s
Wavelength ( λ ) = 5 m
To find : Frequency ( f ) = ?
Formula : -
v = f λ
f = v / λ
= 210 / 5
f = 42 Hz
Answer:
I think the answer might be the first one
Answer:
Explanation:
We are given that
Length of wire,L=14 cm=
1 m=100 cm
Current,I=1.5 k A
Magnetic force,F=(-0.2i+0.2 J)N
Magnetic force,F=
By comparing on both sides
When the current flows in positive x direction
Then,
By comparing on both sides we get
Magnetic field,
Answer:
9517.2 lbm
Explanation:
Electricity consumption = 14000 kWh/year
Fuel consumption = 900 gal/year
Amount of CO₂ produced per gallon = 26.4 lbm/gal
Amount of CO₂ produced per kWh = 1.54 lbm/kWh
Amount of CO₂ produced in one year
Reduction would be
The reduction in the amount of CO₂ produced is 9517.2 lbm
