The gravitational force exerted by the planet Earth on a unit mass at a distance r from the center of the planet is F(r) = GMr R

bagirrra123 [75]

Answer:

Yes the function is continuous.

Step-by-step explanation:

Given

$F(r)=\frac{GMr}{R^{3}}(r< R)$ and $F(r)=\frac{GM}{r^{2}}(r\geq R)$

For a function to be continuous we should have

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Thus

$\lim_{r\rightarrow R^{-}}F(r)=\frac{GMR}{R^{3}}=\frac{GM}{R^{2}}$

Similarly we have

$\lim_{r\rightarrow R^{+}}F(r)=\frac{GM}{R^{2}}$

thus we can see that

$\lim_{r\rightarrow R^{-}}F(r)=\lim_{r\rightarrow R^{+}}F(r)$

Hence the function is continuous.

Scientists found that the body of a male consists of 3.58×10^-4 lbs of zinc. What is the number written in standard notation?

notka56 [123]

Answer:

The number is 0.000358 lbs.

Step-by-step explanation:

Scientists found that the body of a male consists of $3.58 \times 10^{-4}$ lbs of zinc.

This is a scientific way of writing a number.

For, example 0.0023, a number in normal or standard notation can be scientifically written as $2.3 \times 10^{- 3}$ .

So, in our case, the number is $3.58 \times 10^{-4}$ lbs and we have to write this number in standard notation.

Then the number is 0.000358 lbs. (Answer)

The difference between two integers is 32.The ratio of these integers is 1:3.Find these integers

shutvik [7]

Answer:

16 and 48

Step-by-step explanation:

let the 2 integers be x and 3x ← ratio 1 : 3

Then

3x - x = 32 ← difference between the integers

2x = 32 ( divide both sides by 2 )

x = 16

and 3x = 3 × 16 = 48

Since magnitude of difference is 32

We can also express the difference as

x - 3x = 32

- 2x = 32 ( divide both sides by - 2 )

x = - 16

and 3x = 3 × - 16 = - 48

The 2 integers are 16 and 48 or - 16 and - 48
