The object will fall through a distance of 638.45 m.
Considering the question given above, the following data were obtained:
Time (t) = 11.3 s
<h3>Height (h) =? </h3>
<u>NOTE</u>: Acceleration due to gravity (g) = 10 m/s²
We can obtain the height as illustrated below:
H = ½gt²
H = ½ × 10 × 11.3²
H = 5 × 127.69
<h3>H = 638.45 m</h3>
Therefore, the distance the object will fall is 638.45 m

Answer:
0.63m
Explanation:
Volume expansivity = change in volume/original volume×temp change
Volume expansivity p = 3x
p = ∆V/V∆t
x is the linear expansivity
Given
x = 6 x 10^-4
p = 3x
p = 3(6 x 10^-5)
p = 18×10^-5
Volume = 100m³
∆t = 45-10 = 35°C
Required
Change in volume ∆V
Substitute the given values into the formula
18×10^-5 = ∆V/100(35)
18×10^-5 =∆V/3500
∆V = 3500×0.00018
∆V = 0.63m
Hence the increase in volume of the Mercury is 0.63n
Answer:
light potential energy is converted into electrical potential energy.
Explanation:
A solar heat absorbs the light that creates pairs of electron - holes, these free charges when moving create a current, the light energy stored in the radiation is converted into electrical energy within the n-p junctions.
In summary, light potential energy is converted into electrical potential energy.
C. The center of mass and center of gravity will coincide if the acceleration due to gravity is constant or uniform.
<h3>What is center of mass?</h3>
The center of mass of an object is the unique point where the weighted relative position of the distributed mass sums to zero.
<h3>What is center of gravity?</h3>
Center of gravity is the point from which the weight of a body or system may be considered to act.
Thus, the center of mass and center of gravity will coincide if the acceleration due to gravity is constant or uniform.
