d.) a and b only
This is because sound needs a medium to travel. It can travel in a solid (the fastest) and air for example. Sound waves cannot propagate through a vacuum and since space is a vacuum the answer is a and b only.
True, the electric field produced by a uniform, infinite plane of charge does not depend on the distance from the plane.
<h3>
What is electric field?</h3>
Electric field is the region of space at which electric force is felt.
E = kq/r²
where;
- r is the distance of the charge
at infinite plane, r → ∞, and E = 0
Thus, the electric field produced by a uniform, infinite plane of charge does not depend on the distance from the plane.

True. When you learn something new neurons make connections and retain that knowledge. That means the more you learn a skill the more connections you make and the more muscle memory you get from doing that skill. Thus you get better at that skill.
Answer:
9800 Pa
Explanation:
Data: pressure-?
Force- mass ×acceleration
= 50× 9.8m/s^2
=490N
Area= 500cm^2=0.05m^2
pressure= force/ area
p=F/A
P= (490N)/( 0.05m^2)
=9800 Pa
Answer:
C. They are too close to the sun.
Explanation:
- Due to their relative location the gas giant such as neptune and Uranus are mostly cold and icy planets as they are located deep into the solar system and have large distance firm the sun.
- As compared to those of the earth and other rocky planets. Due to their distance they consist of primitive atmosphere and have slow rotation and movement.
