Answer:

30%

Explanation:

Total profit=$25000

Initial investment=$10000

Return on investment is given by

RoI=(Gain from investment-cost of investment)/cost of investment

$RoI=\frac {25000-10000}{10000}\times 100=150%$

RoI=150% but since it's over 5 years, we distribute for 5 years hence annual $RoI=\frac {150}{5}=30%$

Therefore, RoI=30%

Air bags are designed to deploy in 10 ms. Given that the air bags expand 20 cm as they deploy, estimate the acceleration of the

joja [24]

As it is given that the air bag deploy in time

$t = 10 ms = 0.010 s$

total distance moved by the front face of the bag

$d = 20 cm = 0.20 m$

Now we will use kinematics to find the acceleration

$d = v_i*t + \frac{1}{2}at^2$

$0.20 = 0 + \frac{1}{2}a*0.010^2$

$0.20 = 5 * 10^{-5}* a$

$a = 4000 m/s^2$

now as we know that

$g = 10 m/s^2$

so we have

$a = 400g$

so the acceleration is 400g for the front surface of balloon

x rays with wavelength of 2.0nm scatter from a nacl crystal with plane spacing 0.281 nm find the scattering

ValentinkaMS [17]

Explanation:

It is given that,

Wavelength of x-rays = 2 nm

Plane spacing, d = 0.281 nm

It is assumed to find the scattering angle for second order maxima.

For 2nd order, Bragg's law is given by :

$2d\sin\theta=n\lambda$

For second order, n = 2

$\sin\theta=\dfrac{n\lambda}{2d}\\\\\sin\theta=\dfrac{2\times 2\ nm}{2\times 0.28\ nm}\\\\\theta=\sin^{-1}(7.14)$

Here, θ is not defined. Also, the wavelength of x-rays is more than the plane spacing. It means that it cannot produce any diffraction maximum.

How long does it take for a rotating object to speed up from 15.0 rad/s to 33.3 rad/s if it has a uniform angular acceleration o

Leona [35]

Answer:

it takes 5.22 seconds

Explanation:

$angular \: acceleration \: = \frac{angular \: velocity}{time}$

t = (33.3 - 15) ÷ 3.45

t = 18 ÷ 3.45

t = 5.22 sec
