<h2>
Option C is the correct answer.</h2>
Explanation:
Gravitational force is given by
G=6.674×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²
M = Mass of object 1
m = mass of object 2
r = Distance between objects.
Here only variable is r value.
In case 1
In case 2
Option C is the correct answer.
They're similar in the sence that they involve the perception of light, they're different because they're different perceptions of light.
Hope this helped!
Answer:
the final temperature is T2= -126.5°C
Explanation:
Since the gas behaves as an ideal gas
Initial state) P1*V1=n*R*T1
Final state) P2*V2=n*R*T2
where P= gas pressure , V=volume occupied by the gas , n= number of moles , R= ideal gas constant , T= absolute temperature
dividing both equations
(P2/P1)*(V2/V1)=T2/T1
since P2=2*P1 and V2=1/4*V1 , T1=20°C=293K
2*1/4=T2/T1
T2=T1/2 = 293K/2 = 146.5K
T2= 146.5K= -126.5°C
Answer: No, The energy will remain the same
Explanation: Doubling the mass and leaving the amplitude unchanged won't have any effect on the total energy of the system.
At maximum displacement, E=0.5kA^2
Where E = total energy
K = spring constant
A = Amplitude
From the formula above : Total Energy is independent of mass,. Therefore, total energy won't be affected by Doubling the mass value of the object.
Also when the object is at a displacement 'x' from its equilibrium position.
E = Potential Energy(P.E) + Kinetic Energy(K.E)
P.E = 0.5kx^2
Where x = displacement from equilibrium position
E = Total Energy
K. E= E-0.5kx^2
From the relation above, total energy is independent of its mass and therefore has no effect on the total energy.
