Answer:
6.48*10⁻⁷ C
Explanation:
- By definition, the capacitance of a capacitor is expressed as follows:
- where Q is the charge on one of the plates of the capacitor, and V the potential difference between the plates.
- The maximum electric field, the potential difference, and the distance between plates are related by the following expression:
- Replacing by the givens, we can find V as follows:
- Now, we can find the maximum charge Qmax, as follows:
- The maximum charge that the capacitor can hold is 6.48*10⁻⁷ C.
Answer:
Vf = 210 [m/s]
Av = 105 [m/s]
y = 2205 [m]
Explanation:
To solve this problem we must use the following formula of kinematics.
where:
Vf = final velocity [m/s]
Vo = initial velocity = 0 (released from the rest)
g = gravity acceleration = 10 [m/s²]
t = time = 21 [s]
Vf = 0 + (10*21)
Vf = 210 [m/s]
Note: The positive sign for the gravity acceleration means that the object is falling in the same direction of the gravity acceleration (downwards)
The average speed is defined as the sum of the final speed plus the initial speed divided by two. (the initial velocity is zero)
Av = (210 + 0)/2
Av = 105 [m/s]
To calculate the distance we must use the following equation of kinematics
44100 = 20*y
y = 2205 [m]
