Ответ:
the nucleus is the center of the atom, made up of protons and neutrons, without the nucleus you'd just have a bunch of electrons floating around; the nucleus is positively charged
protons are the positively charged particles that sit within the nucleus
neutrons are particles of no charge that sit within the nucleus, and because they have no charge, they do not cancel out the positive charge of the protons, making the nucleus positive
electrons are negatively charged particles that float around the nucleus in an area known as the electron cloud, they orbit around the nucleus because they are attracted to the positive charge of the nucleus (caused by the protons), with charges, opposites attract

Ответ:
The length of the log is 180 cm
Explanation:
From the question given above, the following data were obtained:
Time = 2 hours
Speed = 1.5 cm/min
Distance =?
Next, we shall convert 2 hours to minutes. This can be obtained as follow:
1 h = 60 mins
Therefore,
2 h = 2 × 60
2 h = 120 mins
Finally, we shall determine the Lenght of the log. This can be obtained as follow:
Time = 120 mins
Speed = 1.5 cm/min
Distance =?
Speed = distance / time
15 = distance / 120
Cross multiply
Distance = 1.5 × 120
Distance = 180 cm
Therefore, the length of the log is 180 cm
