False!
It’s false. The answer is False.
Given: Energy E = 5.53 X 10⁻¹⁷ J; Velocity of light c = 2.998 x 10⁸ m/s
Planck's constant h = 6.63 x 10⁻³⁴ J.s
Required: Frequency f = ?
Formula: E = hc/λ and Frequency f = V/λ
λ = (6.63 x 10⁻³⁴ J.s)(2.998 X 10⁸ m/s)/(5.53 x 10⁻¹⁷ J)
λ = 3.59 X 10⁻⁹ m
For Frequency f = ?
f = c/λ
f = 2.998 x 10⁸ m/s/3.59 x 10⁻⁹m
f = 8.35 x 10¹⁶ Hz
Answer:
Explanation:
First of all, we need to find the pressure exerted on the sphere, which is given by:
where
is the atmospheric pressure
is the water density
is the gravitational acceleration
is the depth
Substituting,
The radius of the sphere is r = d/2= 1.1 m/2= 0.55 m
So the total area of the sphere is
And so, the inward force exerted on it is
Since two identical bulbs are connected in this circuit in series combination
So here same current will flow into the circuit
So here we can say
also we know that
also it is given that bulbs are identical so we have
as we have
so now we can say
so here voltage across C and D is 1.5 volts
The answer is B electrons will be rubbed from one surface to another
