Answer:
3.65 x mass
Explanation:
Given parameters:
Time = 20s
Initial velocity = 0m/s
Final velocity = 73m/s
Unknown:
Force the ball experience = ?
Solution:
To solve this problem, we apply the equation from newton's second law of motion:
F = m 
m is the mass
v is the final velocity
u is the initial velocity
t is the time taken
So;
F = m (
) = 3.65 x mass
TRUE
They propagate perpendicular to each other in the case of an Electromagnetic waves....
Both can be seen in the case of a moving charge
Hope this helps!
Answer:
Explanation:Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.
Answer:
22.8077659955 m deep
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
Time taken to fall through the foam
Distance is given by
The vat is 22.8077659955 m deep
Answer:
r = √ G c M ρ R/S
Explanation:
For this exercise we will use the equilibrium equation
F₁- F₂ = 0
F₁ = F₂
Where F₁ is the gravitation force and F₂ the force of the radiation pressure.
The equation for gravitational force
F₁ = G m M / r²
Density is defined by
ρ = m / V
m = ρ V
F₁ = G M ρ V / r²
The radiation pressure has as an expression
P = S / c
Where S is the vector of Poynting (intensity) and c the speed of light
The pressure is defined by
P = F₂ / A
F₂ = P A
F₂ = A S / c
Let's match the two equations
G M ρ V / r² = A S / c
The volume of a body is the product of its area by the other dimension
V = A R
G M ρ (A R) / r² = A S / c
r = √ G M ρ R c / S
r = √ G c M ρ R/S
