Name three types of energy that exist in a large piece of charcoal on a grill in the sunlight. Explain why the charcoal has each
1 answer:
Answer:
A large piece of charcoal on a grill in the sunlight (if it's burning) will consist of the following types of energy:
- Chemical
- Heat and
- Light
Explanation:
Charcoal is basically carbon which is produced when wood is heated strongly in the absence of oxygen. From a chemistry point of view, charcoal contains combustible carbon whose chemical formula is C. Sometimes, which is water may be found in it but in very small units.
All matter contains Heat energy. Charcoal is not an exception. As the charcoal burns, the heat energy is produced along with Light energy.
Light comes in many forms such as Infrared rays, Xrays, Visible Spectrum light, etc.
The glow which the coal gives off fall under the visible spectrum of light.

The question is incomplete but still I answer to assume your thinking.
The picture is attached below!.
Here,
F is the force with which you pull up the incline.
N is the normal force.
w is the weight acting downward.
Axis are mentioned in the attached picture.
Concept:
You can see there is no movement of object in the y-direction that means acceleration is zero in y-direction, sum of all the forces in y-direction equal to zero.
According to newton second law,
<span>∑ F = ma
</span>As, acceleration is zero in y-direction, so right hand side is zero in the above equation.
<span>∑ F = 0</span>
N-wcosθ=0
N= m*g*cos25°
N= m*(9.8)*(0.9063)
N= 8.8817*m
By putting the value of mass(m)(not given in the question) you will get the answer.
Hopefully, this is the answer of your question.

Answer:
Approximately .
Explanation:
.
.
Notice that sine waves and
share the same frequency and wavelength. The only distinction between these two waves is the
in
.
Therefore, the sum would still be a sine wave. The amplitude of
could be found without using calculus.
Consider the sum-of-angle identity for sine:
.
Compare the expression to
. Let
and
. Apply the sum-of-angle identity of sine to rewrite
.
.
Therefore, the sum would become:
.
Consider: would it be possible to find and
that satisfy the following hypothetical equation?
.
Simplify this hypothetical equation:
.
Apply the sum-of-angle identity of sine to rewrite the left-hand side:
.
Compare this expression with the right-hand side. For this hypothetical equation to hold for all real and
, the following should be satisfied:
, and
.
Consider the Pythagorean identity. For any real number :
.
Make use of the Pythagorean identity to solve this system of equations for . Square both sides of both equations:
.
.
Take the sum of these two equations.
Left-hand side:
.
Right-hand side:
.
Therefore:
.
.
Substitute back to the system to find
. However, notice that the exact value of
isn't required for finding the amplitude of
.
(Side note: one possible value of is
radians.)
As long as is a real number, the amplitude of
would be equal to the absolute value of
.
Therefore, the amplitude of would be:
.
Answer:
Acceleration
Explanation:
The quantity of the rate of change of velocity is termed the acceleration of the body.
Acceleration is the rate of change of velocity with time;
A =
A is the acceleration
v is the final velocity
u is the initial velocity
t is the time taken
