Solar energy is energy that is produced using the sun's rays.
Answer:
ΔV = 20.1 V
Explanation:
As the positive plates are connected to each other, the capacitors are connected in parallel, so the total system load is the sum of the charges on each capacitor.
Q = Q₁ + Q₂
The charge on each capacitor is
Q₁ = C₁ ΔV₁
Q₁ = 24 10⁻⁶ 25
Q₁ = 6.00 10⁻⁴ C
Q₂ = C₂ ΔV₂
Q₂ = 13 10⁻⁶ 11
Q₂ = 1.43 10⁻⁴ C
The total set charge is
Q = (6 + 1.43) 10⁻⁴
Q = 7.43 10⁻⁴ C
The equivalent capacitance is
C_eq = C₁ + C₂
C_eq = (24 + 13) 10⁻⁶
C_eq = 37 10⁻⁶ F
Let's use the relationship to find the voltage
Q = C_eq ΔV
ΔV = Q / C_eq
ΔV = 7.43 10⁻⁴ / 37 10⁻⁶
ΔV = 2.008 10¹
ΔV = 20.1 V
This voltage is constant in the combination so it is also the voltage in capacitor C1
If force is applied at 30 degree with the horizontal
then first we will find the components of force in two directions
now we can find normal force by balancing the forces in Y direction
now since block is moving with constant speed
so here forces along horizontal plane will be balanced also
Now the weight of the box is defined as
now plug in all values
Heat must be added to raise the temperature from 20.0 •C to 82 •C is
Q= (4200 x 1.8 + 880 x 1.3) x (82 - 20) = 539648J
