The resistance 2 Ω, 4 Ω and 8 Ω are connected in parallel. Their equivalent
Zigmanuir [339]

Answer:

The answer to your question is the letter B. R = 8/7 Ω

Explanation:

Data

R1 = 2 Ω

R2 = 4Ω

R3 = 8Ω

To calculate the total resistance use the formula

         1/R = 1/R1 + 1/R2 + 1/R3

-Substitution

         1/R = 1/2 + 1/4 + 1/8

- Look for the Greatest common factor

              2   4   8    2

               1   2    4   2

                    1    2   2

                          1

The GCF = 2 x 2 x 2 = 8

-Sum up the fractions

                 1/2 + 1/4 + 1/8 = (4 + 2 + 1) / 8

                                        = 7/8

-Find R

               1/R = 7/8    then, R = 8/7 Ω

Hydroelectric power is produced by
scoundrel [369]

Hydro electric power is the process of  production of electricity from the mechanical energy of water.

In the process of generation of  hydro electricity ,large dams are constructed  in which the water is stored.The water present at top of the dam has potential energy.The water is driven downward  with high pressure. During the falling of water,the potential energy of the water is converted into equivalent kinetic energy. The water coming down with a heavy speed is allowed to fall on a turbine which is connected to a generator.

The mechanical energy of water drives the turbine and electricity is generated due to the electromagnetic induction .

Hence the option A is right i.e falling water that turns the turbine.

A 12.0kg microwave oven is pushed 14.0m up the sloping surface of a loading ramp inclined at an angle 37 degrees above the horiz
Semenov [28]

Answer:

Answered

Explanation:

a) What is the work done on the oven by the force F?

W = F * x

W = 120 N * (14.0 cos(37))

<<<< (x component)

W = 1341.71

b) F_f=\mu_k N

F_f=0.25\times12\times9.8

= 29.4 N

W_f= F_f\times x

W_f= 29.0\times 14 cos(37)

W_f= 328.72 J = 329 J

c) increase in the internal energy

U_2 = mgh

= 12*9.81*14sin(37)

= 991 J

d) the increase in oven's kinetic energy

U_1 + K_1 + W_other = U_2 + K_2

0 + 0 + (W_F - W_f ) = U_2 + K_2

1341.71 J - 329 J - 991 J = K_2

K_2 = 21.71 J

e) F - F_f = ma

(120N - 29.4N ) / 12.0kg = a

a = 7.55m/s^2

vf^2 = v0^2 + 2ax

vf^2 = 2(7.55m/s)(14.0m)  

V_f = 14.5396m/s

K = 1/2(mv^2)

K = 1/2(12.0kg)(14.5396m/s)

K = 87.238J
