8 0

Answer: Work done is 18J

Explanation:

Force F = (Fx, Fy) and Displacement S = (Sx,Sy)

Fx=7N

Fy=-1N

Sx=3m

Sy=3m

F=(7,-1)N and S=(3,3)m

Work done is calculated by taking dot product of force and displacement vector

W=F·S

W=7×3 + (-1)×3

W=21+(-3)=18J

What relationship exists between the amplitude of a wave and amount of disturbance in the water?
guapka [62]
A wave is a result of the disturbance in the equilibrium state.  There are two types of wave, transverse and longitudinal. Transverse wave affects amplitude while longitudinal wave affects the frequency of the wave. As for the transverse wave, the magnitude of the perpendicular disturbance of the wave is directly proportional to the amplitude of the wave. The higher the transverse disturbance the higher the amplitude.

Use the following d/t graph to determine the velocity of the object
marin [14]

Answer:

1/3 m/s

Explanation:

Because the graph goes from 3 to 8 on the Y axis we know that each line is 0.5   and on the X axis each line is  1,   Then,  the slope , or velocity, is 1/3

see?   This graph is kinda set up to throw  you.  

Is there a  1/3 option for this ??

A runner with a mass of 62 kg running at speed of 0.8m/s ​
sashaice [31]

Answer:

so the kinetic energy is 20Nm

Explanation:

mass of the body=m=62kg

velocity of the body=v=0.8m/s

K.E.=?

AS WE KNOW THAT

K.E.=\frac{1}{2}mv²

putting values

K.E.=\frac{1}{2}}×62kg×(0.8m/s)²

K.E.=31kg×0.64m²/s²

K.E.=19.84Nm≈20Nm

i hope it will help you:)
