Answer:
D. Net Force
Explanation:
The overall force on an object is called the net force. When the net force is zero, the forces are balanced, and when it is nonzero, the forces are unbalanced.
The correct answer is D. Net Force.
The overall force on an object is called the net force. It is the vector sum of all the individual forces acting on the object. When the net force is zero, the forces are balanced and the object is either at rest or moving at a constant velocity. When the net force is nonzero, the forces are unbalanced and the object will accelerate in the direction of the net force.

Explanation:
When the sun shines equally on both hemispheres, it is called the equinox.
An equinox is defined as an event in which a planet’s subsolar point passes through the Equator. The equinoxes are the time when both the Northern and Southern Hemispheres experience equal amounts of daytime and nighttime.
There are two equinoxes that take place in a year - the spring equinox and the autumn equinox. During these times, the Earth's axis is not tilted towards or away from the sun which results in equal amounts of daylight and darkness in both the Northern and Southern Hemispheres. The spring equinox marks the beginning of spring season in the Northern Hemisphere, while the autumn equinox marks the beginning of autumn in the Southern Hemisphere.
Thus, when the sun shines equally on both hemispheres, it is called the equinox.

The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Carbon dioxide (CO2) is a type of gas that naturally exists in the atmosphere. It is primarily released from three key sources, which include:
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
The three primary sources of carbon dioxide (CO2) in the atmosphere are the respiration of organisms, the burning of fossil fuels, and deforestation or land use changes.
Yet due to human activities like industrialization and deforestation, the amounts of CO2 in the atmosphere have been increasing at an unprecedented rate, leading to global climate change.

electromagnetic wave, mechanical wave, or both.
Electromagnetic wave travels faster through air than metal.
Option A
Explanation:
There are different kinds of wave energy. The most significant are electromagnetic and mechanical waves. The mechanical waves propagate through the medium by transfer of energy by vibrating of particles in medium.
So, the more number of particles present in the medium, the more fast the mechanical wave can propagate. So the mechanical waves travel faster in metals consisting of more number of free charge carriers. But electromagnetic waves does not need any of the medium to propagate. So it can travel faster in air than in metals.
Accuracy relates to how close a measurement is to the true value, whereas precision refers to how similar multiple measurements are to each other. Assuming Student A's measurements were close to 47.32g and each other, they were both accurate and precise. Student B's would be imprecise but precise if they were not close to 47.32g but close to each other, while Student C's measurements would be neither if they were scattered and not close to 47.32g.
In Physics, when we discuss measurements, two important concepts come up: accuracy and precision. Accuracy refers to how close a measurement is to the actual, true value, in this case, 47.32g. Precision, on the other hand, signifies how close several measurements are to each other, irrespective of how accurate they are.
