Answer: a) 7,00 centimeters
(b) 259. 19 feet
(c) 3110.28 inches
(d) 0.049 miles
Explanation:
(a) We know that 1 meter = 100 centimeters
Therefore,
(b)Since 1 meter = 3.28084 feet
Then,
(c) Since, 1 feet = 12 inches.
(d)
❤this is what i found hope it explains
Answer:
The ratio of T2 to T1 is 1.0
Explanation:
The gravitational force exerted on each sphere by the sun is inversely proporational to the square of the distance between the sun and each of the spheres.
Provided that the two spheres have the same radius r, the pressure of solar radiation too, is inversely proportional to the square of the distance of each sphere from the sun.
Let F₁ and F₂ = gravitational force of the sun on the first and second sphere respectively
P₁ and P₂ = Pressure of solar radiation on the first and second sphere respectively
M = mass of the Sun
m = mass of the spheres, equal masses.
For the first sphere that is distance R from the sun.
F₁ = (GmM/R²)
P₁ = (k/R²)
T₁ = (F₁/P₁) = (GmM/k)
For the second sphere that is at a distance 2R from the sun
F₂ = [GmM/(2R)²] = (GmM/4R²)
P₂ = [k/(2R)²] = (k/4R²)
T₂ = (F₂/P₂) = (GmM/k)
(T₁/T₂) = (GmM/k) ÷ (GmM/k) = 1.0
Hope this Helps!!!
Answer:
Explanation:
The change in potential is then defined as the negative of the work done by that force. ... You can't have work done by gravity AND a change in gravitational potential energy. You have to do it one way or the other. This means that the most important step in solving work-energy problems is choosing a system.
the phenomenon is An object that has potential energy can transfer that energy into kinetic energy when the object begins to move, due to its mass or position. For example, a person jumping on a trampoline has potential energy when they reach the peak of a jump, and their force changes direction from upward to downward.
<u>Statement</u><u>:</u>
A body is under the action of a force F such that the force-displacement graph of the body is semicircle as shown above. The work done on the body by the force in moving through 24 meters.
<u>To </u><u>find </u><u>out</u><u>:</u>
The work done by the body.
<u>Solution</u><u>:</u>
- Here force is F and let us consider the displacement as s.
- We know, work done = Fs.
- Here the area under the curve is Fs, i.e., work done.
- We know, area of a semicircle = where r is the radius.
- Here, radius (r) = 24 m
- Therefore, work done
<u>Answer</u><u>:</u>
The work done is 288π m².
