A planet is orbiting a nearby star. Suppose that the star’s gravity increases over time. What effect will this increase most lik
ely have on the planet’s path of motion? A.
The planet will continue to move in an elliptical orbit around the star.
B.
The planet will begin to orbit the star at a constant speed.
C.
The shape of the planet’s orbit will change from elliptical to circular.
D.
The planet’s orbital path will become smaller and its orbital period will increase.
E.
The planet will begin to orbit the star in the opposite direction.
Planets orbit around the Sun (star) due to the gravity of this star which pulls down them around it. This gravity is the vital force which maintains the elliptical path of their orbit.
If this force of gravity will change it will affect the celestial bodies revolving around it like a planet as this force of gravity is directly proportional to mass and inversely proportional to the distance between them.
According to the question if the gravity of the star increases it will change the orbital path of the planets as they will be more pulled towards the sun which will decrease the distance between the star and planet and the orbital path will become smaller and the orbital period will increase.
Due to their function, nerve fibers which carry afferent impulses are known as afferent nerves or sensory nerves, and those nerve fibers which carry efferent impulses are known as efferent nerves or motor nerves.
The climate of a region is determined through the observation of weather patterns over a long time- usually at least 15 years- in a region. Studying climate change would therefore also take very long time as meteorologists attempt to perceive changes in these weather patterns. In this case 30 years can be enough to notice a significant increase in rainfall patterns which can be classified as climate change.
