B.
Im not sure of the depth ( 8ft 16ft?) can't remember, the ground temperature is always about 70 degrees F. that temperature is from the heat of the core dissipating outwards. So geothermal conditioning is simply forcing the air in that are in the ground, into your home

Answer:
the velocity of the swimmer at the bottom of the slide is 6.26 m/s
Explanation:
The computation of the velocity of the swimmer at the bottom of the slide is given below:
v = √2gh
= √2 × 9.8 × 2
= 6.26 m/s
Hence, the velocity of the swimmer at the bottom of the slide is 6.26 m/s
Answer:
v = -227.785 m/s
Explanation:
The electric field exerts the following force on the electric particle:
F = qE
The magnetic field exerts the following force on the particle::
F = qvB
Total force acting is:
F = qvB + qE
v = -227.785 m/s
Answer:
-20v
Explanation:
Data provided in the question as per the given situation
L = 45 mH
f = 250 Hz
V_o = 20V
Based on the above information, let us assume voltage across inductor be V at t
So,
t = 2 ms
Now
The voltage at time t = 2.0 ms is
= -20 volt
= -20v
We simply solved the above equation so that the correct voltage could come
