C.the acceleration is doubled
Position 1 I believe because that is when the potential energy is released on the downfall
Answer:
50.3N
Explanation:
Work done = force x distance
422J. = force x 8.39m
÷8.39 both side to get force
Force is 50.3N to 1 d.p.
Check:
50.3 x 8.39=422.017J
Same as 422J to 1 d.p
Answer:
e*P_s = 11 W
Explanation:
Given:
- e*P = 1.0 KW
- r_s = 9.5*r_e
- e is the efficiency of the panels
Find:
What power would the solar cell produce if the spacecraft were in orbit around Saturn
Solution:
- We use the relation between the intensity I and distance of light:
I_1 / I_2 = ( r_2 / r_1 ) ^2
- The intensity of sun light at Saturn's orbit can be expressed as:
I_s = I_e * ( r_e / r_s ) ^2
I_s = ( 1.0 KW / e*a) * ( 1 / 9.5 )^2
I_s = 11 W / e*a
- We know that P = I*a, hence we have:
P_s = I_s*a
P_s = 11 W / e
Hence, e*P_s = 11 W
If resistor A, B and C are arranged in series, same current will flow in all the resistors and 2A will flow is resistor C.
<h3>What is series circuit?</h3>
This is the type of circuit arrangement in which the resistors are arranged in series order.
In this type of circuit arrangement, same current flows in every component of the circuit.
Thus, if resistor A, B and C are arranged in series, same current will flow in all the resistors and 2A will flow is resistor C.
