Momentum=mass*velocity=40,000*11=440,000 kg m/s. A
The notion of potential energy is related to the work done by the forces on the physical system to move it from one position to another in space. That is to say in practical terms it can be calculated by the Force applied in a certain distance. Mathematically this is

Here,
PE = Potential Energy
W= Work
F = Force
d = Distance
Replacing we have,


Therefore the potential energy stored in the bow the moment before the arrow is released is 12J.
Let’s use the *queue dramatic voice* LAW OF THE CONSERVATION OF MOMENTUM!
m1v1i + m2v2i = m1vf + m2vf
m1v1i - m1vf = m2vf - m2v2i
m1(v1i - vf) = m2(vf - v2i)
m2 = [m1(v1i - Vf)] / (vf - v2i)
m2 = [(1)(5 - -1)] / (-1 - -2)
m2 = 6 / 1
m2 = 6 kg
And that’s your final answer! Please press “Thanks”!
Answer:

Explanation:
The force of gravity between two objects is given by:

where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is their separation
In this problem, we have
m1 = m2 = 1170 kg is the mass of each car
r = 28 m is their separation
Substituting,

A
most common source of phosphates in the soil is the weathering of the mineral apatite.
Explanation:
Apatite is a group of phosphate minerals like hydroxylapatite, fluorapatite, and chlorapatite. When apatite rocks weather, they release the phosphate minerals mainly in the form of PO₄ ³⁻ . These minerals become dissolved in water (hydrosphere), where they are readily available to plants and other organisms in the biosphere. The phosphates are taken up and used in biosynthesis. When these organisms die and become buried with sediments, the phosphate gets back to the lithosphere as sedimentary rock.
