You use the equation kinetic energy = 1/2 mass X velocity^2 so your answer is 25000J.
Need Height and Mass, since Gravitational Potential Energy is equal to mgh. Not really sure what you’re asking though. Please elaborate and I can give a better answer!
Answer:
Lithium and francium belong to the same group because they both have the same number of valence electron. Having the same number of valence electron puts them in the same group. Group members possess similar properties. So Lithium and francium have similar properties because they have the same number of valence electron.

Answer:
a) L = 3.29 10⁻⁴ H, b)U = 5.33 10⁻² J
Explanation:
a) The inductance is a solenoid this given carrier
L =
The magnetic field inside the solenoid is
B = μ₀
hence the magnetic flux
Ф_B = B. A = μ₀
we substitute in the expression of inductance
L = N² μ₀ A /l
let's find the area of each turn
A = π r²
A = π 0.02²
A = 1.2566 10⁻³ m²
let's calculate
L = 250² 4π 10⁻⁷ 1.2566 10⁻² / 0.3
L = 3.29 10⁻⁴ H
b) The stored energy is
U = ½ L i²
let's calculate
U = ½ 3.29 10⁻⁴ 18²
U = 5.33 10⁻² J
