One one-thousandth is expressed by which prefix?

What is the distance between a 900 kg compact car and a 1600 kg pickup truck if the gravitational force between them is about 0.

elena-14-01-66 [18.8K]

Answer:

The distance is 0.96m

Explanation:

Given

m1= 900kg

m2= 1600kg

Force F= 0.0001nN

G=6.67430*10^-11 Nm^2/kg^2

Required

The distance r

Step two:

the formula for the force is given as

F = Gm1m2/r2

make r subject of the formula

$r= \sqrt{\frac{Gm1m2}{F} }$

$r= \sqrt{\frac{6.67430*10^-11*900*1600}{0.0001} }\\\\r= 0.00009610992/0.0001`}\\\\r= 0.96m$

How do objects and substances have kinetic energy??<br><br> I need help ASAP!!

9966 [12]

Objects and substances in motion have Kinetic Energy.

Explanation:

Kinetic Energy is the motion of objects, substances, molecules, atoms .

Whenever an object starts to move, it is in motion. Kinetic Energy is generated, when the object moves and its potential energy gets dropped with the movement. Kinetic Energy is found in every object that moves.

The Kinetic Energy of an object depends both on its mass and its speed. Kinetic Energy increases as mass and speed are increased.

Example: By using the wind flow from wind turbines, the Kinetic energy in the wind can be transformed to generate electricity by using generators.

Vlad [161]

B. Energy

A power company charges its customers for electricity based upon B. Energy.

<h3>Explanation:</h3>

Kilo-watt Hours (kWh) is the unit that measures the electricity consumption of customers. Since Power is defined as the rate at which electrical energy is transferred by an electrical circuit per unit time,

$P = \frac{E}{t} \\E= P\times t$

If energy is transmitted at a constant rate over a period of time, the total energy in kilowatt hours is the product of power in kilowatts(kW) and time in hours (h)

$1\ kWh = 3.6\times 10^6\ Joules$
