The correct choice would be
B) The Sun’s mass is much greater than Earth’s
The sun as we know has greatest mass in our solar system and lighter objects tends to orbit around the heavier objects. the mass of earth is very much smaller as compared to that of the sun. hence the earth orbits around the sun due to the force of gravitational attraction between the two objects.
.Internal energy is the total potential and kinetic energies in a substance, and thermal energy is the part of internal energy that can be transferred to another substance. Thus, option "C" is correct.
<h3>What is the thermal energy Meaning?</h3>
Thermal energy, is internal energy present in a system in a form of thermodynamic equilibrium probity by its temperature.
Thermal energy cannot be transformed to useful work as easily as the energy of systems that are not in conditions of thermodynamic equilibrium.
Thus, option "C" is correct

Answer:
The pressure corresponding to the absolute zero temperature is 0.997atm.
Explanation:
To solve this question, you draw a straight vertical line with the boiling point temperature and pressure on top of the line and the freezing point temperature and pressure on the lower part. The absolute temperature somewhere in the middle of the line with the pressure to be obtained.
So, we have;
0- (-19) / 100 - (-19) = P - 0.9267 / 1.366 - 0.9267
19 / 119 = P - 0.9267 / 0.4393
Cross multiply, we have
19 * 0.4393 = 119(P -0.9267)
8.3467 = 119P - 110.2773
119P = 118.624
P = 0.997 atm
So at 0°C, the pressure of the thermometer is 0.997atm.
Answer:
The motion of a simple pendulum is very close to Simple Harmonic Motion (SHM). SHM results whenever a restoring force is proportional to the displacement, a relationship often known as Hooke's Law when applied to springs. Where F is the restoring force, k is the spring constant, and x is the displacement.
where θ is the angle the pendulum makes with the vertical. For small angles, sin(θ)∼θ, which would then lead to simple harmonic motion. For large angles, this approximation no longer holds, and the motion is not considered to be simple harmonic motion.
