Answer:
GPE = 388.08 Joules.
Explanation:
Given the following data;
Mass = 0.550kg
Speed = 335 m/s
Height = 72 meters
We know that acceleration due to gravity, g is equal to 9.8 m/s²
To find the gravitational potential energy;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
Where;
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;
GPE = 388.08 Joules.
Answer:
B. coefficient
Explanation:
i dont have to explain right?
Answer:
Explanation:
Let:
We need to know for which value of 
the function 
is equal to 
:
Therefore, we need to solve for the previous equation for :
Replacing the values of and :
Subtract 4 from both sides:
Multiply both sides by -1
Divide both sides by 3:
Therefore the value of for which is 
.
Verify the result:
The energy of a substance is defined as the capacity to do work.The energy may be possessed by the body in various forms.It may be kinetic,potential,magnetic.electric etc.
a- The energy can be transformed from one form to another form.It is called energy conversion.
c-The power defined as the consumption of energy per unit time.
Here E is the energy and W is the work done,t is the time.
d-The S.I unit of energy is Joule[J].
Hence the correct answer to the question is b. the ability to do work
