The total mass of 131.29 amu

= 2,196.10⁻²² grams

<h3><em>Further explanation</em></h3>

Inside the atom consists of a nucleus containing 3 basic particles namely protons and neutrons, while electrons move around the nucleus.

The mass number is not the same as the atomic mass. The mass number is the number of protons and neutrons in one atom. While the atomic mass is a number that expresses the mass of one atom.

Atomic mass is expressed in special units, namely atomic mass units because the atomic mass is very small if expressed in units of grams or milligrams

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 C-12 atom = 12 atomic mass units

1 atomic mass unit = 1/12 x mass 1 atom C-12

The mass of 1 proton is equal to the mass of 1 neutron, equal to 1 atomic mass unit and electrons have a smaller mass than both.

electron mass = 9.11.10⁻²⁸ g

proton mass = 1.6726.10⁻²⁴ g

neutron mass = 1,675.10⁻²⁴ g

The proton mass is considered to be equal to 1 atomic mass unit and a neutron which has a slightly larger mass is also considered to be equal to 1 atomic mass unit

1 unit of atomic mass (amu) = 1.6726.10⁻²⁴ g

So if there are 131.29 amu, you can convert them into

= 131.29 x 1.6726.10⁻²⁴ g

= 219,595.10⁻²⁴

= 2,196.10⁻²² grams

We know avogadro's number = 6.023 x 10²³
1 amu = 1 atomic mass unit = 1/ (6.023 x 10²³) gm = 1.66 x 10⁻²⁴grams
<span>Now, to convert amu to grams,
 131.29 amu = 131.29 x 1.66 x 10</span>⁻²⁴grams
<span>= 2.18 x 10</span>⁻²²<span> grams is the answer</span>

The electric potential, when measured at a point equidistant from two particles that have charges equal in magnitude but of oppo
Reika [66]

Answer:

C) equal to zero

Explanation:

Electric potential is calculated by multiplying constant and charge, then dividing it by distance. The location that we want to measure is equidistant from two particles, mean that the distance from both particles is the same(r2=r1). The charges of the particle have equal strength of magnitude but the opposite sign(q2=-q1). The resultant will be:V = kq/r

ΔV= V1 + V2= kq1/r1 + kq2/r2

ΔV= V1 + V2= kq1/r1 + k(-q1)/(r)1

ΔV= kq1/r1 - kq1/r1

ΔV=0

The electric potential equal to zero

If an airplane were traveling westward with a thrust force of 450 N and there was a headwind (drag) of 200 N, what would the res
Marat540 [252]

Answer:

The resulting net force on the airplane would be 250N.

Explanation:

It would be 250N because to find the amount of Newtons you would have to do 450 minus 200. 450 minus 200 equals 250. You can check by adding 200 plus 250 and it equals 450 the which is the "thrust".

A child bounces a 51 g superball on the sidewalk. The velocity change of the super bowl is from 22 m/s downward to 14 m/s upward
noname [10]

Answer:

F=1.02x10^{-3} N

Explanation:

From the exercise we know:

m=51g*\frac{1kg}{1000g}=0.051kg

v_{1}=-22m/s

v_{2}=14m/s

t_{2}-t_{1}=1800s

So, the average acceleration is:

a=\frac{v_{2}-v_{1}}{t_{2}-t_{1}}=\frac{(14-(-22))m/s}{1800s}=0.02m/s^2

The average force is:

F=m*a=(0.051kg)(0.02m/s^2)=1.02x10^{-3} N
