Answer:
0.88 mm
Explanation:
Given
Wavelength of the atoms, λ = 502 nm = 502*10^-9 m
Radius of the screen away from the double slit, r = 1 m
We know that Y(20) = 11.4*10^-3 m
d = (20 * R * λ) / Y(20)
d = (20 * 1 * 502*10^-9)/11.4*10^-3
d = 1*10^-5 / 11.4*10^-3
d = 0.88 mm
Therefore, the distance of separation between the two slits is 0.88 mm
Answer:
equal
Explanation:
Because of Newton's third law
Answer : The electric current of a circuit is, 2.8 A.
Explanation :
Using Ohm's law :
Or,
where,
R = resistance of a circuit = 28 Ω
V = voltage of circuit = 76 volts = 76 V
I = current flowing in a circuit = ?
Now put all the given values in the above formula, we get :
Therefore, the electric current of a circuit is, 2.8 A
As we know that P=IV so P = (0.5A)(4.5V)
P= 2.25 watt
