The velocity component at any point along a position vs. time graph is equal to the intercept of the tangent line at that point.

vodka [1.7K]

Answer:

False.

Rather, the velocity component at any point is equal to the ****slope**** of the tangent line of the position-time graph at that point.

Step-by-step explanation:

Mathematically, velocity at any point, v= dx/dt at that point; which is the instantaneous slope of the tangent of the position-time graph at that point.

HELP PLZ.....I NEED THIS....One wheel of a bicycle has 24-inch diameter. About how many feet will the bicycle travel when the wh

Ne4ueva [31]

First, find the circumference of the wheel using $C=2 \pi r$

You know that your diameter is 24. To find the radius, divide the diameter by 2, which is 12.

Input 12 as r and simplify. -> $C=2 \pi (12)$
$C=24 \pi$

estimate your Pi as 3.14
$C=24(3.14)$

and multiply. C=75.36

Now you know the distance of one full revolution in inches. To find 200 revolutions, multiply that answer by 200.

75.36 * 200 = 15,072 inches

But because this is in inches, you have to find the answer in feet, so just divide that answer by 12.

15,072 / 12 = 1,256 ft

pd-100 has a half-life of 3.6 days. if one had 6.02 x 1023 atoms at the start, how many atoms would be present after 20.0 days?

Irina18 [472]

<span>half-life means you divide by 2
21.6 / 3.6 = 6 hf (hf = half-life)
then you divide by 2^6
6.02 x 10^23 / 2^6 = 9.40625 x 10^21 atoms
--------------
26
3hf ===> 2^3
10.0 / 2^3 = 1.25 gram (remaining)
answer : 10 - 1.25 = 8.75g
-------
27
128 / 2^n = 2
64 = 2^n
n = 6
24 /6 = 4
4 days is the half-live of the sample
-----------
28
2.5/4.46 of 50% initial mass
(2.5/4.46) x 0.5 x 2 = 0.5605 g
answer: 2 - 0.5605 = 1.4395 g
----------
29
2^7 = 128
so 7 half-lifes
7* 8040 = 56200 days
----------
30
the time of 10 half-lifes
= 10 x 0.334s = 3.34s </span><span>
