Answer:

1.2 mi/hr/sec

Explanation:

<em>a = Vf - Vi / t (formula)</em>

-----------------------------------

     6mi/hr - 0 mi/hr        6 mi/hr

a = ____________ =    _______ = 1.2 mi/hr/sec

If a blender is plugged into a 168 V outlet that supplies 80.8 A of current, what amount of
VladimirAG [237]

Answer:

Power = 13.5744 kilowatts

Explanation:

Power is the rate at which work is done. ... Great power means a large amount of work or energy developed in a short time. For example, when a powerful car accelerates rapidly, it does a large amount of work and consumes a large amount of fuel in a short time.

Formula for power = work/time

= IVT/T

= IV

Where I is the current

And V is the voltage

The voltage V supply = 168 v

The current A supply = 80.8 A

Power = 80.8*168

Power = 13574.4 watts

Power = 13.5744 kilowatts

If spring has a spring constant of 500 N/m and is stretched .50 meters,how much energy is stored in the spring ((show work for f
Free_Kalibri [48]

Answer:

The energy stored is: 62.5 Joules

Explanation:

Given

k = 500N/m --- spring constant

x = 0.5m --- stretch

Required

The amount of energy

This is calculated as:

U = \frac{1}{2} kx^2

U = \frac{1}{2} * 500N/m * (0.5m)^2

U = 250N/m * (0.5m)^2

U = 62.5\ J

As the distance between two charged particles increases, the force of attraction __________(increases/decreases). This is a(n) _
zubka84 [21]

Answer: decreases.

direct.

Explanation:

when you have two objects which are far apart from each other,  when the distance increases the forces of attraction decreases and vice versa when the distance decreases the forces of attraction also increases.

this is a direct relationship, from careful observation and monitoring of the simulation, a pattern is noticeable by which an increase in one variable causes an opposite effect on the other variable.
