Answer:
0.34 x 10^-3 m^3
Explanation:
P1 = 6 x 10^5 N/m^2
T1 = 10 degree C = 10 + 273 = 283 K
T2 = 35 degree c = 35 + 273 = 308 K
Pressure remains constant , P2 = P1
P1 V1 = R T1
V1 = (8.314 x 283) / (6 x 10^5) = 3.92 x 10^-3 m^3
Now, let the Volume is V2
P1 V2 = R T2
V2 = (8.314 x 308) / (6 x 10^5) = 4.26 x 10^-3 m^3
Change in volume, v = V2 - V1 = (4.26 - 3.92) x 10^-3 = 0.34 x 10^-3 m^3
You're probably refering to a theory. A theory is a conceptual framework about a certain topic out of which we can infer many different hypothesis on the same topic that should prove to be correct. If they're not, then the theory is not a theory in reality, because the inferences made out of the theory are not correct.
Answer:
F' = 162 units
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:
where,
F = gravitational force = 18 units
G = Gravitational Constant
m₁ = mass of object 1
m₂ = mass of object 2
r = distance between objects
Therefore,
Now, if we change the value of distance to one-third of original value, then:
r' = r/3
using eqn (1):
F' = 9(18 units)
<u>F' = 162 units</u>
Answer:
0.04225 Nm
Explanation:
N = Force applied = 5 N
= Coefficient of static friction = 0.65
d = Diameter of knob = 1.3 cm
r = Radius of knob =
Force is given by
When we multiply force and radius we get torque
Torque on thumb
Torque on forefinger
The total torque is given by
The most torque that exerted on the knob is 0.04225 Nm
