Answer:
An arcsecond, also called a second of an arc, is a unit of measurement that amounts to one sixtieth of an arcminute. Simply put, it is equal to 1/3600 degrees of an arc. The symbol used to mark an arcsecond is the double quote.

Answer: The area of the parking lot is 14,400 meters squared.
Explanation:
We have the dimensions of the parking lot.
60m by 240m
The units used here are meters.
Now, if we want to know the area of the parking lot is equal to the product between the length and the width:
A = 60m*240m = 14,400 m^2
The area of the parking lot is 14,400 meters squared.
Explanation:
The area between the speed-time graph f a body and time axis measures the distance travelled by the body
Loop law for v1, r1, r2, r3
lv1 = current from v1
Ir3 = current pass r3
- v1 + Iv1(r1) + Iv1(r2) + Ir3(r3) = 0
-5 + Iv1(200) + Iv1(200) + Ir3(100) = 0
400Iv1 = 5 - 100Ir3 ...(1)
current law at B
Iv1 + I1 - Ir3 - I2 = 0
Iv1 + 0.001 - Ir3 - 0.005 = 0
Iv1 = Ir3 + 0.004 ...(2)
solve by using (1),(2)
Ir3=0.0068A, Iv1=0.108A
Vb = Ir3(r3) = 0.0068(100) = 0.68V
Va = Vb + Iv1(r2) = 0.68 + 0.0108(200) = 0.68 + 2.16 = 2.84V
power = I^2(r)
