Answer:
speed is increasing.
this is because the graph has a positive slope (due to it going up ), if it were decreasing, the graph would be going down
Answer:
c. detecting the gravitational effect of an orbiting planet (The Wobble"") by looking for the Doppler shifts in the star's spectrum
Explanation:
In a solar system the mass of the star and planets affect each other's orbital movements. The center of gravity of a star and a planet is inside the star. This causes the star to be closer and farther from the Earth at different times. Due to this wobble the star appears to be red shifted when it is farther and blue shifted when it is closer.
When the mass of the planet is high, like a hot Jupiter it causes more wobble i.e., change in radial velocity. This makes it easier to detect the planet. The earliest hot Jupiter found by this method is the planet 51 Pegasi b.
The correct answer is A. the magnet to become stronger
The stronger the electric current in the piece of metal, the stronger the magnetic field will be.
The correct answer is D: which is none of the above.
