Answer:
The potential difference across the plates is 226 V.
Explanation:
Given;
area of the capacitor plate, A = 0.2 m²
separation, d = 0.1 mm = 0.1 x 10⁻³ m
charge on each plate, Q = 4 x 10⁻⁶ C
Charge on the capacitor is given by;
Q = CV
Where;
C is the capacitance of the capacitor, given as;
C = ε₀A / d
Then, the potential difference across the plates is given by;
Therefore, the potential difference across the plates is 226 V.
Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy = mass*velocity²
KE = mv²
KE = (100kg)(5m/s)²
KE = (100kg)(25m/s²)
KE = 1250
KE = 1250J
