Answer:

The voltage remains constant.

Answer:

The voltage in the circuit remains same. However the current drawn by the circuit will increase.

Explanation:

According to Ohm's Law:

V=IR

If we halved the resistance let:

R'=R/2

then

I'=2I in order to kept the Voltage same. Also the resistance is the opposition to the current. So, if resistance will halved then obviously current will double

So when we put these value in to Ohm's Law the results is:

V'=I'R'

V'=2I(R/2)

V'=IR which is equal to first voltage. Hence,

V'=V

Energy in a spring:

E = 0.5 * k * x²

k spring constant = 800 n/m
x stretch of the spring = 5 cm = 0.05 m

E = 0.5 * 800 * 0.05² = 1

Why are the layers of the earth in the order that they are in?
REY [17]

Answer:

Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core.

A red blood cell is 7 x 10-6 m in size. This means it is 7 __________ in size. What unit completes the sentence?
aalyn [17]

If a red blood cell is 7 x 10^-^6 m in size, it means that such a cell is 7 microns or micrometer in size. The unit that completes the sentence will, thus, be microns or micrometer.

According to international system of measurement:

  • 10^{-1} m = decimeter
  • 10^{-2} m = centimeter
  • 10^{-3} m = millimeter
  • 10^{-6} m = micrometer or micron
  • 10^{-9} m = nanometer

Thus, a measurement of 7 x 10^-^6 m is the same is 7 micons or 7 micrometer.

A passenger on a Ferris wheel moves in a vertical circle at a constant speed. Are the forces on her balanced?
vovikov84 [41]

C.  The force is a constant change,  because her position on the Ferris wheel will constantly change.  I believe this is the answer, but use sources to double check.  I might use different vocab. then your teachers.
