Answer:

1.685185185185185 (you can round to whatever your teacher asks)

Explanation:

Formula for Density

D=m/v (Density equals mass over volume)

273/162

(/) means division.

malfutka [58]

From the information given,

diameter of ornament = 8

radius = diameter/2 = 8/2

radius of curvature, r = 4

Recall,

focal length, f = radius of curvature/2 = 4/2

f = 2

Recall,

magnification = image d

A coach is hitting pop flies to the outfielders. if the baseball (m= 145 g) stays in contact with the bat for 0.04 s and leaves

vekshin1

At the start, the ball is at rest and therefore, u=0 m/s. As it leaves the bat, v= 50 m/s

From equations of motion, v=u+at = at (since u=o)
a=v/t = 50/0.04 = 121250 m/s^2

From Newton's second law,
F=ma = 145/1000 *1250 = 181.25 N

PLZ HELP ME!!!!!!!!

Answer:

1. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.77955 m

now frequency is given by

$f = \frac{343m/s}{ 0.77955m}$

f = 440 Hz

2. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.52028 m

now frequency is given by

$f = \frac{343m/s}{ 0.52028m}$

f = 659.3 Hz

3. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.65552 m

now frequency is given by

$f = \frac{343m/s}{ 0.65552m}$

f = 523.25 Hz

4. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 587.33 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{587.33}$

$\lambda = 0.584 m$

5. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 493.88 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{493.88}$

$\lambda = 0.6945 m$

6. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 698.46 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{698.46}$

$\lambda = 0.491 m$

7. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.5840 m

now frequency is given by

$f = \frac{343m/s}{0.5840m}$

f = 587.3 Hz

8. Frequency = speed / wavelength

here we know

speed = 343 m/s

wavelength = 0.4375 m

now frequency is given by

$f = \frac{343m/s}{0.4375m}$

f = 784 Hz

9. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 783.99 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{783.99}$

$\lambda = 0.4375 m$

10. Wavelength = speed / Frequency

here we know

speed = 343 m/s

Frequency = 659.26 Hz

now wavelength is given by

$\lambda = \frac{343m/s}{659.26}$

$\lambda = 0.520 m$
