LekaFEV [45]

Answer:

It will take the plant $4\frac{4}{9}$ days or 4.44 days to grow to a height of 200 inches tall.

Explanation:

From the question, the rate at which the species of the bamboo tree grows is 36 inches per day.

To determine how long it would take a plant 40 inches tall initially to grow at this rate (that is, 36 inches per day) to a height of 200 inches.

This means we will calculate the number of days it will take the plant to grow additional 160 inches ( 200 inches - 40 inches) at this rate.

Now,

If the plant grows 36 inches in 1 day

then it will grow 160 inches in x days

x = (160 inches × 1 day) / 36 inches

x = 160 / 36

x = $4\frac{4}{9}$ days or 4.44 days

Hence, it will take the plant $4\frac{4}{9}$ days or 4.44 days to grow to a height of 200 inches tall.

Suppose there are 100,000 atoms of a radioactive substance that has a ½ life of 10 minutes. How many atoms will remain after 40

dezoksy [38]

Answer:

c. 12,500

Explanation:

Original number of atoms = 100,000 atoms

Half- life = 10min

Unknown:

The number of atoms that will remain after 10min = ?

Solution:

The half - life is the time taken for half of a radioactive substance to decay by half.

Time taken Number of atom half life

10min 100000 _

20min 50000 1

30min 25000 2

40min 12500 3

• what is the typical distance between two adjacent pins on a 14-pin dual-in-line ic package?

muminat

A 14 pin dual-in-line IC package[14 DIL] is an integrated socket which is most popular form of IC package and has a wide range of application in digital electronics.

The 14-pin DIL has two pairs per side and each pair contains seven connecting pins.

The pairs of pins are arranged linearly one after another.The typical dimensions of width is 6.5 mm and the typical dimension of length is 18 mm.

we are asked to calculate the typical distance between two adjacent pins.

The typical distance between two adjacent pins is calculated as-

$Typical\ distance =\frac{dimensional\ length}{number\ of\ pins\ in\ each\ row}$

$=\frac{18 mm}{7}$

$= 2.5714 mm$ [ans]

Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the gr

DiKsa [7]

Answer:

(2/3) times height collision occur

Explanation:

for ball A

from the kinematic equation

the distance of ball A is

$x_A = v_0 t + \frac{1}{2} at^2$

$v_0* t$ = velocity ( time ) = distance

since ball is at height, the above equation changes as

$x_A = H - \frac{1}{2} gt^2$

for ball B

$xB = v0 t - \frac{1}{2} gt^2$

the condition of collision is

xA = xB

$vA = - 2vB$ (given)

from the kinematic equation

the speed of the ball A is

$v_A = u- gt$

since initial speed of the ball A is zero

, so

$v_A = -gt$

the speed of the ball B is

$v_B = v_0 - gt$

since $v_A = - 2v_B$

$-gt = -2 ( v_0 - gt)$

$-gt = -2 v_0 +2gt$

$3gt =2 v_0$

$t = \frac{2v_0}{3g}$

since $x_A = x_B$

$H - \frac{1}{2} gt^2= v_0 t - \frac{1}{2} gt^2$

$H = v_0 t$

$= v_0 (2v_0/3g)$

$= \frac{2 v_0^2}{ 3g}$

$x_A = 2 (\frac{v_0^2}{ 3g})- \frac{1}{2} gt^2$

$= 4 \frac{v_0^2}{9g} = (2/3) H$

so, (2/3) times height collision occur
