Two teams of students are having a tug-of-war. Team 1 pulls with a force of 150 newtons (N) while team 2 pulls with a force of 2
Elena-2011 [213]

Answer:

Team 2

Explanation:

Team 1 pulls with a frce of 150N

Team 2 pulls with a force of 200N

In a tug-of-war, the goal is to pull the other team over a certain distance and this is determined by the force applied.

If the two team pulls with equal force, there wold be no net force and the teams stays in the same position.

In this case however, team 2 pulls with a force greater than team 1. There is a net force of 50N in favor of Team 2. This means team 2's force would neutralize that of team 1 and the excess force would be use in pulling Team 1

An element gain two electrons and has 16 protons and 17 neutrons. What is the atomic mass of this element and what is the charge
Taya2010 [7]

Answer:

atomic mass= 33

Charge= -2

Explanation:

In an atom, are contained three SUBATOMIC particles viz: proton and neutron found in the nucleus, electrons surrounding the nucleus. Protons contain the positive charge of an atom while electrons contain the negative charge of an atom. The number of protons and electrons in an atom determines the charge of an ion (charged atom). Also, the atomic mass or mass number of that atom is got by adding the number of protons + number of neutrons.

In this case where the number of protons and number of neutrons are 16 and 17 respectively, the mass no. or atomic mass is 17 + 16 = 33.

Also, since two electrons are gained by this atom, it means the electron numbe, which is normally equal to the proton number in a neutral atom, will be increased by 2. Hence, the electron number will be 18 in this case.

The charge of the atom= no. of protons - no. of electrons = 16 - 18 = -2.
