I believe the correct answer from the choices listed above is option C. When a baseball is thrown straight upward, <span>its acceleration at its greatest height would be 0 m/s. This is because at max height velocity of the ball is zero which means that acceleration as well is zero. Hope this answers the question. Have a nice day.</span>
Answer:
A radio telescope helped the astronomers discover the CMB.
Explanation:
- Penzias and Wilson while experimenting with a radio telescope in 1964, accidentally discovered the radiation that exists universally also known as the CMB.
- This was used to support the "Big Bang Theory" and not the "Steady State Theory"
- CMB is the faint cosmic radiation that fills up the universe. It provides important data for understanding early universe.
- This data tells us about the composition of the universe and its age which raises new questions about the universe.
Explanation:
to go fast from to one place to another
Refraction: It is the phenomena of bending of light when it changes it medium. This can rarer to denser or denser to rarer. Refraction and Diffraction are just bending of light. Whereas, Reflection is getting back the light you've thrown from a source of light.
The answer to this question should be a gravitational force.
A gravitational force is something that sort of attracts two things of mass. This force must never ever pull the objects of mass apart. It must always try to pull them together. So, judging by the question we can tell that the two masses in this situation are the leaf and the ground. When the leaf fell on the ground this was the gravitational force pulling the leaf down so it connects with the ground.
