Answer:
F = 2.25 N
Explanation:
Given that,
Charge 1,
Charge 2,
Distance between charges, d = 10 cm = 0.1 m
We need to find the electric force between charges. The formula that is used to find the electric force is given by
Hence, the force between charges is 2.25 N.
Answer:
v = 5.88 10⁷ m / s
Explanation:
For this exercise we use the relation
E = m c²
also indicate that all energy is converted into kinetic energy
E = K = ½ (M-2m) v²
where m is the mass of antimatter and M is the mass of the ship's mass. Factor two is due to the fact that equal amounts of matter and antimatter must be combined
we substitute
m c² = ½ (M-2m) v²
v² =
let's calculate
v =
v =
v = 5.88 10⁷ m / s

Answer:
Wave speed = 50 m
Explanation:
Given
Wavelength = 5 m
Frequency = 10 Hz = 10
wave speed = ?
We know that all waves have same relationship among wavelength λ, frequency f and speed v , which is given by
v = fλ
Therefore wave speed = 10 x 5 m = 50 m
Answer:
Explanation:
Given
Diver is at a depth of inside the water
As we go down pressure increases due to the weight of liquid column above us
Pressure difference is given by
Where =density of liquid
h=depth
g=acceleration due to gravity
So external-internal pressure difference is
