Answer:
60 Ω
Explanation:
R(com) = 15 Ω
1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn
1/15 = 1/20 + 1/R2
1/R2 = 1/15 - 1/20
1/R2 = (4 - 3) / 60
1/R2 = 1/60
R2 = 60 Ω
así, la combinada de resistencia necesaria es 60 Ω
Answer:
So it will lift the mass by h = 17 m
Explanation:
As per energy conservation we know that
here we know that
now we have
so work done by the engine is 250 J
now we have
Answer:
The period will be doublef because increasing the mass increases the period linearly.
Explanation:
A stiffer spring with a constant mass decreases the period of oscillation. Increasing the mass increases the period of oscillation
In the electromagnetic spectrum, "Blue" is the "highest" <span>frequency color of visible light.
Or I</span>n the electromagnetic spectrum, "Red" is the "Lowest" frequency color of visible light.
Hope this helps!
