Answer:

Allotropes

Explanation:

Because it is the same element the chemical conposition is the same i.e. The atoms that make the substances are identical. Allotropes can be crystalline or amorphous and sometimes they can be varied in properties.

2. A sports car claims to increase its speed from rest to 25 m/s in 3.6 seconds. How far will the car go in

Kaylis [27]

Explanation:

we first find acceleration by

V=u +at (v is the final velocity,u the initial velocity,a the acceleration and t the time taken)

v=25 m/s

u=0

t=3.6s

substituting we get

25=0 + a (3.6)

25=3.6a (diving both sides by 3.6 we get)

a=6.94 m/s^2

to find distance we use the equation v^2=u^2 + 2ad

25^2 =0^2 + 2 (6.94)do

625=13.88d (dividing both sides by 13.88 we get );

d=45m

An object is going 22 m/s and is 3 kg. find momentum

MAVERICK [17]

So what you wanna do is take your two givens. 22 and 3. Now you wanna take 22 and divide that by 3. And that gives you 7.33. Now if your answer HAS to be a whole number it'll be 66.

Answer:

The value is $A = 0.00214 \ m^2$

Explanation:

From the question we are told that

The wavelength is $\lambda = 500 \ nm = 500 *10^{-9} \ m$

The diameter of the aperture is $d = 30 \mu m = 30*10^{-6} \ m$

The distance of the screen from the aperture is $D = 350 \ m m = 0.350 \ m$

Generally the distance from the center the the edge of the central bright fringe is magmatically reparented as

$y = \frac{m * \lambda * D}{d}$

Generally m = 1 because after the central bright fringe we have the first order fringe

$y = \frac{1 * 500 *10^{-9} * 0.350}{30*10^{-6}}$

=> $y =0.00583 \ m$

Generally the area of the central bright fringe

$A = 2 \pi * y^2$

=> $A = 2 * 3.142 * 0.00583^2$

=> $A = 0.00214 \ m^2$

A soccer coach riding his bike reaches his office in xx hours. If he travels at 24 km/h, he reaches his office 5 minutes late. I

Elina [12.6K]

Answer:

18 km

Explanation:

Let 'd' be the distance between his house and office.

Normal time taken to reach the office = 'x' hours.

If speed is 24 km/h, time is increased by 5 minutes.

If speed is 30 km/h, time is reduced by 4 minutes.

We know that,

Time taken = Distance traveled ÷ Speed

So, when speed is 24 km/hr, time is increased by 5 minutes.

$1\ min = \frac{1}{60}\ h\\5\ min =\frac{5}{60}=\frac{1}{12}\ h$

So, time is $x+\frac{1}{12}$

Therefore,

$x+\frac{1}{12}=\frac{d}{24}\\\\x=\frac{d}{24}-\frac{1}{12}\\\\x=\frac{1}{12}(\frac{d}{2}-1)---------1$

Now, when speed is 30 km/h, time is reduced by 4 minutes or $\frac{4}{60}=\frac{1}{15}\ hours$

So, time now is $x-\frac{1}{15}$

Again using the time formula, we have

$x-\frac{1}{15}=\frac{d}{30}\\\\x=\frac{d}{30}+\frac{1}{15}\\\\x=\frac{1}{15}(\frac{d}{2}+1)-------------2$

Equations (1) and (2) are equal. So,

$\frac{1}{12}(\frac{d}{2}-1)=\frac{1}{15}(\frac{d}{2}+1)\\\\\frac{15}{12}(\frac{d}{2}-1)=\frac{d}{2}+1\\\\\frac{5d}{8}-\frac{5}{4}=\frac{d}{2}+1\\\\\frac{5d}{8}-\frac{d}{2}=1+\frac{5}{4}\\\\\frac{5d-4d}{8}=\frac{4+5}{4}\\\\\frac{d}{8}=\frac{9}{4}\\\\d=\frac{9\times 8}{4}=\frac{72}{4}=18\ km$

Therefore, the office is 18 km from his house.
