Mass (M) of space shuttle = 1.0 × 105 kg.
Altitude (r) = 200.0 km

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: To \: \: Find :}}} \\$

The force of gravity that the space shuttle experiences = ?

$\\\purple{\maltese}\large\underline{\underline{\red{\sf\:\: Solution :}}} \\ \\$

$\purple{\maltese}\large\underline{\underline{\sf\:\: using \: formula :}} \\ \\$

$\bigstar \: \underline{ \boxed{\sf { \pink{g = \frac{G \: M}{{r }^{2} }}}}} \\ \\$

$\\ ❒\: \: \underline{\textbf {Putting values \: in \: the \: \: given \: formula :}} \\$

$\sf \implies \: g = \frac{G \: M}{{r }^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-11} × 1.0×10^5}{(2×10^5)^{2} } \\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}}\\$

$\sf \implies \: g = \frac{6.67×10^{-6}}{4×10^{10}} \\$

$\sf \implies \: g =1.6675×10^{-6-10}\\$

$\sf \implies \: g =1.6675×10^{-16}\: Newton\\\\$

$\:\:\:\:\:\:\:\qquad\rule{150pt}{2pt} \\\\$

Henceforth, the force of gravity experienced by the shuttle is 1.6675×10^N

which expression represents purely real numbers and which expression represents non-real complex number?

Ray Of Light [21]

Incomplete question. However, I provided some explanation about non-real complex numbers.

Explanation:

In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.

For example, the numbers 3i, 3 + 5i, 3i/4 are non-real numbers because of the addition of an imaginary part which is denoted by 'i'.

While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

Paul drove 225 miles to visit his parents. The graph below shows the distance traveled and the total time of the trip. Write and

ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

Average speed is the rate of change of total distance covered with time taken .

Average speed = $\frac{total distance }{time}$

To find the total distance covered;

Distance at time 1 = 75miles

Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

Average speed = $\frac{150}{3}$ = 50mph
