If you were going to build a nuclear power plant why wouldn't you build it in the middle of a desert
Tems11 [23]
You won't be able to get enough water for the reactor core cooling (you can use other methods , but more expensive) . The desert temprature is high at day, which will require additional cooling techniques to avoid over-heating the plant. Transmitting the electricity to the industrial , commercial and residual areas will cost more money, as you will need more transmission lines. Transporting the fuel to the desert will cost more at most.

Mostly this plants are established near seas.

HELP! DUE TOMORROW!! specify the independent and dependent variables, as well as constants. 4-6! only!
olga55 [171]

Answer:

the variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variables is the cause and the dependent variables is the effects. It's value depends on the changes in the independent variable.

A tennis player tosses a tennis ball straight up and then catches it after 2.00 s at the same height as the point of release. (a
Readme [11.4K]

Answer:

Part a)

a = -9.81 m/s/s

Part b)

v = 0

Part c)

v = 9.81 m/s

Part d)

H = 4.905 m

Explanation:

Part a)

During the motion of ball it will have only gravitational force on the ball

so here the acceleration of the ball is only due to gravity

so it is given as

a = g = 9.81 m/s^2

Part b)

As we know that ball is moving against the gravity

so here the velocity of ball will keep on decreasing as the ball moves upwards

so at the highest point of the motion of the ball the speed of ball reduce to zero

v_f = 0

Part c)

We know that the total time taken by the ball to come back to the initial position is T = 2 s

so in this time displacement of the ball will be zero

\Delta y = 0 = v_y t + \frac{1}{2} at^2

0 = v_y (2) - \frac{1}{2}(9.81)(2^2)

v_y = 9.81 m/s

Part d)

at the maximum height position we know that the final speed will be zero

so we will have

v_f^2 - v_i^2 = 2 a d

here we have

0 - (9.81^2) = 2(-9.81)H

H = 4.905 m
