Explanation:
1) the diagonal force times the sine of the angle it makes will give you the vertical component or y component . use this to get the vertical components of all the diagonal forces . add all the vertical components as well as the vertical forces together
2) the diagonal force times the cosine of the angle it makes gives the horizontal component or x component. do this to get the x component of all the diagonal forces.
add all the x components as well as the horizontal forces together to get the final x component
3)using the triangle of vectors, the resultant force is calculated
sum of y component = 3.2N
sum of x component= 5.7N
resultant force = 6.5N
Answer:
v = 9.45 m/s
Explanation:
given,
mass of the carpenter = 62.5 Kg
length of rope = 13.4 m
Capable of exerting force = 1034 N
centripetal force acting on the body
F =4.664 v² N
Gravitational force on her =
F = m g
F = 62.5 x 9.81
F = 613.125 N
now,
4.664 v² + 613.125 = 1034
4.664 v² = 420.875
v² = 90.24
v = 9.45 m/s
Maximum speed which she can tolerate = v = 9.45 m/s
Visible light is the spectrum that humans can see ranging from 400-700 nm
I double checked my work and that is great work you have so it's correct
ANSWER:
[i] False.
[ii] Work is the product of force and displacement.
REASONS:
[i] As we already know that temperature is a measure of the average kinetic energy of the particles in an object.
[ii] W = FS
