Answer:
Area = 648.9 m²
Explanation:
Given that, the radius of the circle = 14.37 m
The formula for the area of the circle is shown below:
Thus, applying the values in the above formula as ;
<u>Area = 648.9 m²</u>
Answer:
4km
Explanation:
Distance=speed x time
Knowing this we know the time and speed
so it is 8 x .5= D
And 8 x .5 =4

Answer:
Explanation:
By definition , so we can calculate the total charge that went through the filament since we know the electric current and the time. If the charge of one electron is e, then the total charge will be given by Q=Ne. Combining these equations we get the number of electrons as:
Since the resistivity of tungsten (W) is , then resistance can be calculated using the formula:
Where we already obtained the radius from the diameter. Finally the Voltage will be given by the formula:
To1. PE = mgh
PE potential energy
m mass
g 9.81
h height
P = PE / t
P power
t time
