Answer:
The voltage is 
Explanation:
From the question we are told that
The voltage of the battery is 
The capacitance of the capacitor is 
The resistance of the resistor is 
The time taken is 
Generally the voltage of a charging charging capacitor after time t is mathematically represented as
Here 
is the voltage of the capacitor when it is fully charged which in the case of this question is equivalent to the voltage of the battery so
Answer:
r = 0.56 m
Explanation:
The power emitted by the radar is evenly distributed in a sphere, so let's use the ratio of intensity and power
I = P / A
A = P / I
A = 10.0 / 2.50
A = 4 m²
Let's find the radius of the sphere of this area
A = 4π r²
r = √ A / 4π
r = √ 4 / 4π
r = 0.56 m
Answer:
It is exerted in all directions at sea level, and this is because air molecules move in all directions.
