Answer:
There always is an acceleration in a curvilinear motion, as the velocity vector changes, so always.
Data is inappropriate
here, we need gauge of the wire i.e., diameter of the wire, so that we calculate the resistance by using the formula
R = ρl/A
where R= resistance ; Ω
l = length of wire ; m
A = area of wire ; m²
ρ = resistivity ; Ω-m
But in general ohms law is
V = I R
R = V/I ;
but here we also calculate "R" from length of wire in which the current is flowing.
I hope it is helpful to you.
Answer:
D). energy resulting from the attraction between two masses.
Explanation:
Explanation:
Given that, Tom briskly walks 136 meter East, then turns and walks 100 meters West.
Let East is positive and west is negative.
d₁ = 136 m
d₂ = -100 m
Time, t = 3 minutes = 180 seconds
Average velocity,
So, Tom's average velocity is 1.32 m/s and it is due west.
The equation of the energy of a photon is E=h*f.
If we increase the Planck's constant h, the energy would increase.
For example, lets double the value of Planck's constant and name it H:
H=2*h. Now lets put that into the equation for energy that we will call E₂:
E₂=H*f=2*h*f=2*E.
So we can clearly see that E₂=2*E or that if we double Planck's constant, the energy also doubles.
