To solve this problem we will apply Newton's second law and the principle of balancing Forces on the rope. Newton's second law allows us to define the weight of the mass, through the function
Here,
m = mass
a = g = Gravitational acceleration
Replacing we have that the weight is
Since the rope is taut and does not break, the net force on the rope will be zero.
Therefore the tensile force in the rope is 98N
Yes, for example a plain is moving so it has kinetic energy, it is also high above the ground so it has gravitational potential energy
Answer:
The voltage will be 0.0125V
Explanation:
See the picture attached
A philosophical theory or approach that emphasizes that the existence of the individual person as a free and responsible agent determining their own development through acts of the will.
Answer:
Explanation:
Moles of helium ( n ) = 156.7 / 4 = 39.175
Temperature T₁ = 35.73 +273 = 308.73 K
Volume V₁ = V
Pressure P₁ = 3.55 atm
V₂ =1.75 V
a ) For isothermal change
P₁ V₁ = P₂V₂
P₂ = P₁ V₁ / V₂
= 3.55 X V / 1.75 V
= 2.03 atm.
b ) Work done by the gas = nRT ln(V₂/V₁)
= 39.175 X 8.321 X 308.73 X ln 1.75
= 56318.8 J
Work done on the gas = - 56318.8 J
c ) Since there is no change in temperature , internal energy of gas is constant
Q = ΔE + W
ΔE = 0
Q = W
Work done by gas = heat absorbed
heat absorbed = 56318.8 J
d ) Change in the internal energy of gas is zero because temperature is constant.
