<span>L = m r X v ................this is the cross product of two vectors r and v
L = mvr sin(angle) = (2)(12)(8)sin(143.1degrees) = 115.28 kgm^2/s

Answer:
a) 256 ft
b) 32 ft/s
c) -32 ft/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32 ft/s²
Maximum height = 256 ft
When s = 240 ft
Speed of the ball at 240 ft is 32 ft/s while going up
Now this will be the velocity of the ball when it reaches 240 ft, which will be considered as the initial velocity
Now, initial velocity will be considered as zero
Speed of the ball at 240 ft is -32 ft/s while going down
Answer:
6 The earth come between the sun and moon
7 Full moon
8 entire night side of the earth.
9 The earth atmosphere acts as a prism and filter refracting longer wavelengths of sunlight enough to color the muted reflections from the moon.
Explanation:
The answer would be Exosphere because, there are 3 main regions that circulate oxygen through the Earths system, which are the Biosphere, Atmosphere, and the Lithosphere.
The electric potential energy of the charge is reduced because it decreases with increase in the distance between charges.
<h3>What is electric potential energy?</h3>
Electric potential energy can be defined as the energy needed to move a charge against an electric field.
It is calculated using the formula;
U = Kq1 q2 ÷ r
Where Q = electric potential energy
k = Coulombs constant
q1 and q2 = charges
r = distance of separation
Electric potential energy is inversely proportional to the distance of separation of the charges.
If the distance of the charges changes from 3mm to 6mm, then the electric potential energy of the charges is reduced because it decreases with increase in the distance of the charges.
Therefore, the electric potential energy of the charge is reduced because it decreases with increase in the distance between charges.
