Answer: the object's ability to store charge</h2>
Explanation:
The capacitance is defined as the relationship between the electric charge of each conductor and the potential difference between them. That is, it is the capacity of a device to store electrical charge.
In other words:
It is the property that bodies have to maintain an electric charge.
Mathematically it is defined as:
where:
is the capacitance value of a capacitor. Its unit is Farad ; named in honor of the physicist Michael Faraday
is the electric charge of the conductor, measured in coulombs .
is the electric potential to which the conductor is located, measured in Volt.
Answer:
0.55 s
Explanation:
From the question given above, the following data were obtained:
Height (h) = 1.5 m
Horizontal velocity (v) = 25 m/s
Time of flight (t) =?
The time of flight of the potato talks about the total time spent by the potato in the air i.e the time taken for the potato to get to the ground..
Thus, we can obtain the time of flight of the potato as illustrated below:
Height (h) = 1.5 m
Acceleration due to gravity (g) = 9.8 m/s²
Time of flight (t) =?
H = ½gt²
1.5 = ½ × 9.8 × t²
1.5 = 4.9 × t²
Divide both side by 4.9
t² = 1.5 / 4.9
Take the square root of both side
t = √(1.5 / 4.9)
t = 0.55 s
Thus, the time of flight is 0.55 s
Answer:
Explanation:
<u>Work
</u>
The work done by an external force F when moving an object by a distance X parallel to its direction is
The second Newton's law gives us the net force acting on an object of mass m which is being moved at an acceleration a:
Replacing the last equation into the first equation
And solving for a
There seems to be some kind of mistake in the data provided, we'll use it anyway
It's a very small value as compared to the dimensions of the rest of the problem.
Answer:
We cannot see anything in a completely dark room as there is no light present in the darkroom. (a) After switching on an electric bulb in the dark room as a light source, we can see it as it emits light that reaches our eyes directly.
