A tide of increased range that occurs during the new and full moons is called Spring Tide.
Answer:
E=6.91 N/C
Explanation:
Given that
Linear Charge density ,λ = 5 nC/m
Distance ,R= 13 m
We know that formula for long wire to find electric field

E=Electric field
R=Distance
εo=8.85 x 10⁻¹² C²/N.m²
λ=Linear Charge density
Now by putting the values

E=6.91 N/C
Therefore the electric filed at distance 13 m will be 6.91 N/C
Answer:
True
Explanation: Air resistance (also called drag) is a type of frictional force. Like all frictional forces, the force of air resistance always opposes the motion of an object. Usually, the air resistance force is not very strong.
Answer:
v₁ = u₁/2√3 ≈ 0.866u₁
v₂ = u₁/2 = 0.5u₁
θ = 60°
Explanation:
let u₁ be the initial velocity of the first ball
let v₁ be the final velocity of the first ball
let v₂ be the final velocity of the second ball
For elastic collisions, the angle between the departing masses is 90°
assume the first ball initially moves along the x axis in the positive direction
conservation of momentum
In the y direction, initial momentum is zero
After the collision
mv₁sin30 = mv₂sin60
½v₁ = ½√(3)v₂
v₁ = √(3)v₂
in the x direction,
mu₁ = mv₁cos30 + mv₂cos-60
u₁ = v₁cos30 + v₂cos60
u₁ = (√(3)v₂)½√(3) + ½v₂
u₁ = 2v₂
v₂ = u₁/2
v₁ = √(3)v₂ = √(3)(u₁/2)
