Answer:

A geostationary orbit can be achieved only at an altitude very close to 35,786 kilometres (22,236 miles) and directly above the equator. This equates to an orbital speed of 3.07 kilometres per second (1.91 miles per second) and an orbital period of 1,436 minutes, one sidereal day

Charges of +2 µC and +3 µC are 4 mm from each other. Raina’s group draws four diagrams trying to represent the electrical force

ahrayia [7]

The correct diagram is shown below:

The charges of +2 µC and +3 µC are 4 mm from each other. The diagram below represents the electrical force between the charges. i.e. repulsive force. However the force of repulsion exerted by charge +3 µC on +2<span> µC will be more. The same charges repel each other and opposite charges attract each other.</span>

Alex73 [517]

Your bedroom has a rectangular shape, and you want to measure its area. You use a tape that is precise to 0.001 and find that the shortest wall in the room is 3.547 long. The tape, however, is too short to measure the length of the second wall, so you use a second tape, which is longer but only precise to 0.01 . You measure the second wall to be 4.79 long. Which of the following numbers is the most precise estimate that you can obtain from your measurements for the area of your bedroom?

b)If your bedroom has a circular shape, and its diameter measured 6.32 , which of the following numbers would be the most precise value for its area?

a)30 m^2

b) 31.4 m^2

c)31.37 m^2

d)31.371 m^2

Answer:

Part A

$A = 16.99 \ m^2$

Part B

$A_r =31.37 \ m^2$

Explanation:

From the question we are told that

The shortest wall is $x = 3.547 \ m$

The length of the second wall is $y = 4.79 \ m$

Generally the area is mathematically evaluated as

$A = x * y$

=> $A = 3.547 * 4.79$

=> $A = 16.99 \ m^2$

Given that the diameter is d = 6.32

Then the area is

$A_r = \pi \frac{d^2}{4}$

$A_r =3.142 * \frac{6.32^2}{4}$

$A_r =31.37 \ m^2$

Answer: the basic unit of a chemical element.

Explanation:

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
