Answer:

Distance = 0.921 meters

Work = 13.9 kJ

The neighbor

Double your work

Explanation:

Work = Force × Distance

Distance = Work / Force

Distance = 174J /189 N

Distance = 0.921 meters

Work = force × distance

Work = (613 N) (22.6 m)

Work = 13,900 J

Work = 13.9 kJ

Work is a product of force and distance, expressed as W=Fd where W is work in Nm, F is applied force and d is the distance in m

Since your neighbor pushes 4 times then you just push 1m when he pushes 4m, that is an example. Also, since the neighbor only exerts half the force i.e. 0.5N then you exert full force of 1N

Work from your neighbor will be 4d*0.5F=2dF

Work from you will be dF

Clearly, 2dF=2(dF) hence the neighbor exerts double work

What influences the strength of an electric field?

Slav-nsk [51]

Answer:

Explanation:

The charge alters that space, causing any other charged object that enters the space to be affected by this field. The strength of the electric field is dependent upon how charged the object creating the field is and upon the distance of separation from the charged object.

Answer: $V_{\epsilon}\propto \frac{d\phi_{B}}{dt}$

Explanation:

A direct proportionality means a linear relationship between two variables and rate of change means an application of derivatives. Hence, the mathematical model is:

$V_{\epsilon}\propto \frac{d\phi_{B}}{dt}$
