Answer:
The speed of the cyclist is 2.75 km/min.
Explanation:
Given
To determine
We need to find the speed of a cyclist.
In order to determine the speed of a cyclist, all we need to do is to divide the distance covered by a cyclist by the time taken to cover the distance.
Using the formula involving speed, time, and distance
where
substitute d = 88, and t = 32 in the formula
Cancel the common factor 8
km/min
Therefore, the speed of the cyclist is 2.75 km/min.
Answer:
the energy comes from the increase in the electric field
Explanation:
The capacitance is
C = ε₀ A / d
The electric charge on the condenser plates
Q = C ΔV
The stored electrical energy is
U = ½ C ΔV²
ΔV = E d
U = ½ (ε₀ A / d) (E d)²
U = ½ ε₀ A d E²
We see that the stored energy is proportional to the square of the electric field, so the capacitor can increase its energy with increasing voltage
In short, the energy comes from the increase in the electric field
Wood, water, Forests. The rest can have harm to the nature.
Answer:
4/5 houses
Explanation:
The speed of the first carpenter is:
(1/5 house) / (3/4 day) = 4/15 house/day
The speed of the second carpenter is:
(2/5 house) / (3/4 day) = 8/15 house/day
Together, their combined speed is:
4/15 house/day + 8/15 house/day = 12/15 house/day
= 4/5 house/day
Per day, the two carpenters build 4/5 of a house.
This is false. The reaction force can be determined.
