The answer is 125 Joules
The first thing to take note of is the work equation: W=F×D
Since we already have our force and our distance that will help make this problem easier.
So, W=25*5
W=125
Therefore, our answer is 125 Joules since work is measured in joules
Hope this helped!! :)
Answer:
1) R1 + ((R2 × R3)/(R2 + R3))
2) 0.5 A
3) 3.6 V
Explanation:
1) We can see that resistors R2 and R3 are in parallel.
Formula for sum of parallel resistors; 1/Rt = 1/R2 + 1/R3
Making Rt the subject gives;
Rt = (R2 × R3)/(R2 + R3)
Now, Resistor R1 is in series with this sum of R2 and R3. Thus;
Total resistance of circuit = R1 + ((R2 × R3)/(R2 + R3))
2) R_total = R1 + ((R2 × R3)/(R2 + R3))
We are given;
R1 = 7.2 Ω
R2 = 8 Ω
R3 = 12 Ω
R_total = 7.2 + ((8 × 12)/(8 + 12))
R_total = 7.2 + 4.8
R_total = 12 Ω
Formula for current is;
I = V/R
I = 6/12
I = 0.5 A
3) since current through the circuit is 0.5 and R1 is 7.2 Ω.
Thus, potential difference through R1 is;
V = IR = 0.5 × 7.2 = 3.6 V

Answer:
10.31 m
Explanation:
To find the result you have to use the formula: h = p / eg.
Where: e = 1000Kg/m^3 g=9.8m/s^2 p= 1.01 * 10^5 Pa
The calculation will be:
h= 1.01 * 10^5 / (1000kg/m^2) * (9.8m/s^2)
h= 10.31 m
