Answer:
Given force=10lb
L1=4in converting to feet
But 0.08333ft= 1 inch
Then 4 inch is 0.3332
6inch is 0.49998
But hookes law states
F=Kx where F is force,K is the force constant ,X
K=F/X=10/0.3333=30N/m
Integrating this
Integral of 30x with limit 0.333 to 0.5
F=30x^2/2=15x^2substing the limit
F=(15(0.5^2-0.33^2)=2.08ft-lb
Explanation:
Protons have a positive 1 charge while neutrons do not have a charge; they are neutral
Answer:
1.25C
Explanation:
When capacitance is in series we add them like this: 1/Ctotal = 1/C1 +1/C2 + 1/C3.....
1/C = 1/2 + 1/5 + 1/10 = 5 + 2 + 1/10 = 8/10
C = 10/8 = 1.25
Capacitance = Charge/potential difference(Q/V)
1.25 = Charge/12
Total charge = 1.25 ×12 =15coulombs
The answer would possibly be H in my mind
Answer:
402 J/(kg ⁰C)
Explanation:
m = mass of the sample = 80.0 g = 0.080 kg
T₀ = Initial temperature of the sample = 25 ⁰C
T = Final temperature of the sample = 225 ⁰C
W = Amount of work done by the system = 346 J
U = Increase in internal energy = 6085 J
Q = Amount of heat given to the gas
Amount of heat is given as
Q = U + W
Q = 6085 + 346
Q = 6431 J
Heat received by sample is given as
Q = m c (T - T₀ )
inserting the values
6431 = (0.080) c (225 - 25)
c = 402 J/(kg ⁰C)
