Winds can pull warm air from a warmer area to a colder arena and rise the temperature. It can also do the opposite, bringing cold air from a colder area to a warmer area, dropping the temperature.
let the vector Q is given as
given that
here we know that
now by above equation
so by comparing both sides
b = 0
4c - 3a = 6
also we know that
by solving above equation
a = 12.85 and c = 11.14
so the vector Q is given as
Answer:
<u>Acceleration</u> is the rate of change of velocity of an object.
Formula: Had to take a picture of the formula
The potential energy of the block is given by:
V = m*g*h
m mass
g = 9.81m/s²
h height
The potential energy of a spring is given by:
V = 0.5 * k * x²
k spring constant
x compression of the spring
If the block starts from rest it has potential energy, but no kinetic energy. As it slides down the incline potential energy is converted into kinetic energy. When the block hits the spring the kinetic energy is converted into spring's potential energy. If the spring is fully compressed and the block is at rest again, the block has transferred all its energy into the spring. No energy is lost. So we can write:
m * g * h = 0.5 * k * x²
m = 0.5 kg
g = 9.81 m/s²
h = 2.5m * sin 37° = 1,5 m
x = 0,6 m
Solve for k.
k = 2 * m * g * h / x² = 40.8 N/m
Answer : 
Explanation :
Given that
Radius of sphere 
The distance between the centers of the two spheres is
The charge of the sphere 
The magnitude of the repulsive force between the charges pushing them a part is
Using coulomb law
Hence, this is the required solution.
