Answer:
(n + 246 ) miles
Explanation:
Distance travelled in first week = n miles
Distance traveled in second week = 246 miles
Total distance travelled in two weeks = distance travelled in first week + distance travelled in second week
= ( n + 246) miles
Hello! In order to understand this question. We need to understand the work formula first. Which is represented as:
Work = Force X Distance
In this case, we have our force of 10N and the distance of 50m. So we plug the numbers into the formula to get 500J of work!
Answer:
Some atoms do not have a proton.
Protons have about same mass as electrons.
Protons have the magnitude of charge as neutrons, but are opposite in sign.
Explanation:
Protons are the positive charge particles which are present inside the nucleus and has a mass equal to neutron.
an atom has equal number of electrons and protons hence it is not possible that atom is found in a state where is does not have any proton.
The mass of proton is equal to that of neutron but not electron. Protons are heavier than that of electrons.
Protons are the positively charged particles whereas neutrons do not have any charge present in it.
Hence the selected three options about protons are false.
