Answer:
You would need to type the numbers in the question or you could have added a picture but you didn't so there is no way to answer this question. Have a nice day!
Answer:
14.715 m
Explanation:
Assume that the acceleration due to gravity is 9.81 m/s^2 downwards, take downwards as positive
First second:
v = u + at
v = 9.81 m/s
Second second:
s = ut + (1/2)at^2
s = 9.81(1) + (1/2)(9.81)(1)^2
s = 14.715 m
Answer:
Explanation:
If there is a dielectric slab with thickness less than the distance between the plates is inserted inside a capacitor, then that capacitor can be regarded as two capacitors connected in series.
Let's assume that the slab is placed onto the lower side. So, the capacitance of that part of the capacitor, C1 is
where 
is the permittivity of the slab.
The other part of the capacitor is
Two capacitors are connected in series:
If we know the charge of the plates, we could relate the potential V0 to capacitance via

Answer:
Explanation:
Faraday’s constant can be used to convert the charge (Q) into moles of electrons (n). The charge is the current (I) multiplied by the time
Q = I × t = n × F
Where
Q is charge
I is current = 0.2A
t is time = ?
n is number of mole
F is Faraday constant = 96500C/s
Mass of Au = 0.4 g = 0.0004kg
Molar mass of Au = 197 g/mol
Malar mass = mass / mole
n = 0.4 / 197
n = 2.03× 10^-3 mol
n = 0.00203 mol
t = n × F / I
t = 0.00203 × 96500 / 0.2
t = 979.7 seconds
t = 16.32 minutes.
