Answer:
λ = 11.29 x 10⁻⁷ m = 1129 nm
Explanation:
According to the law of conservation of energy:
where,
λ = maximum wavelength = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
e = charge on electron = 1.6 x 10⁻¹⁹ C
V = stopping poteential = 1.1 V
Therefore,
<u>λ = 11.29 x 10⁻⁷ m = 1129 nm</u>
Answer: Wind energy is powered by wind, and solar energy is powered by the Sun.
The final velocity of the cart at the given mass is 4.36 m/s.
The given parameters;
- <em>mass of the cart, m = 1 kg</em>
- <em>work done on the cart, W = 5 J</em>
- <em>initial velocity of the cart, u = 3 m/s</em>
The distance traveled by the cart is calculated as follows;
Fd = W
mgh = W
The final velocity of the cart is calculated as follows;
Thus, the final velocity of the cart at the given mass is 4.36 m/s.
