Answer:
<h3>40</h3>
Explanation:
Given the following
Ax = 9,
Ay = 12,
Bx = 15
By = 20
Get A and B
A = √9²+12²
A= √81+144
A = √225
A = 15
Get B;
B = √15²+20²
B = √225+400
B = √625
B = 25
get /A+B/
A+B = 15+25
/A+B/ = /40/
Hence the value of /A+B/ is 40

the nucleus is the center of the atom who controls the element.
Answer:
w = 1,066 rad / s
Explanation:
For this exercise we use Newton's second law
F = m a
the centripetal acceleration is
a = w² r
indicate that the force is the mass of the body times the acceleration
F = m 0.58g = m 0.58 9.8
F = 5.684 m
we substitute
5.684 m = m w² r
w =
To finish the calculation we must suppose a cylinder radius, suppose it has r = 5 m
w =
w = 1,066 rad / s
Probable how long they were moving
F= kq1q2/r²
F=9×10^9×2×10^-6×5×10^-6/(0.2)²
F=0.09/0.04
F=2.25N
