Answer:

Their positive charge is located in the small nucleus

Explanation:

Ernest Rutherford performed the gold foil experiment in 1911 where he used alpha particles generated from a radioactive source to bombard a thin gold foil.

In his experiment, he observed that the bulk of the alpha particles passed through the gold foil, just a tiny fraction was deflected back. To explain his findings, Rutherford proposed that an atom is made of positively charged centre where nearly all the mass is concentrated called nucleus. Surrounding the nucleus is a large space containing electrons.

He discovered that other than the nucleus at the center, atoms are mostly just empty space. So A makes the most sense.

An 80 kg long jumper in flight accelerates at a rate of 10 m/s^2. What is the force of the long jumper

Katarina [22]

Answer:

F = 800 N

Explanation:

Given data:

Mass = 80 Kg

Acceleration = 10 m/s²

Force = ?

Solution:

Formula:

F = m × a

F = force

m = mass

a = acceleration

Now we will put the values in formula:

F = m × a

F = 80 kg × 10 m/s²

F = 800 kg.m/s²

kg.m/s² = N

F = 800 N
