Answer:
mass number = protons + neutrons
Answer:
During full moon and new moon, low tides are lowest and the high tide are at the highest.
Explanation:
The tidal bulges are the greater and tidal peak is small at full and new moon, because the tidal forces due to Sun and Moon are synchronized (and incorporate one another accordingly). Higher tides and lower tides, which are still called spring tides, are thus smaller.
ಠ_ಠ Hey, hang on.. you might've made a discovery. Nobody has tested it so how do we know? ಠ_ಠ
One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one. Option A is correct.
<h3>What is electromagnet?</h3>
The magnetic field of an electromagnet is created by an electric current. Electromagnets are caused from conducting wire wriggled into a coil.
A magnetic field is created in the hole by a current passing through the wire.
The magnetic field production is increased by;
1) increasing the number of turns
2) increase the area of the loop
3) by moving the magnet faster
One of them produces a stronger magnetic field than the other one because one of the electromagnets must have more turns of the wire than the other one.
Hence, option A is correct.

Answer:
Explanation:
The radio signal travels to us at the speed of light, so at a speed of
The distance between the spaceship and the Earth is
Since the signal travel by uniform motion, we can write
where
t is the time the signal needs to reach the Earth
By solving the equation for t, we find
