35 protons are present in an element whose atomic number is 35.
<u>Explanation:
</u>
In an atom of an element, the number of protons = atomic number
Number of protons = number of electrons
Mass Number = number of protons + number of neutrons
Hence, an atom with atomic number 35 will have 35 protons.
That ratio is the efficiency of whatever the power went into and came out of. There's no reason the efficiency has to be expressed as a percentage.
Answer:
B:The breakdown of rocks into smaller rocks
Explanation:

Answer:A
Explanation:
Since the bucket of water is constantly in motion it implies a force must be acting on it which allows it to change its Position constantly.
A constant gravity Force must be acting on water . In addition to gravity force a centripetal force must be acting on the water inside the bucket.
Bucket must move with certain velocity in order to avoid spilling of water.
