You hold a spherical salad bowl 50 cm in front of your face with the bottom of the bowl facing you. The salad bowl is made of po

nataly862011 [7]

Answer:

a) q = 39.29 cm , b) h ’= - 3.929 cm the image is inverted and REAL

Explanation:

For this exercise we will use the equation of the constructor

1 / f = 1 / p + 1 / q

where f is the focal length of the salad bowl, p and q are the distance to the object and the image

The metal salad bowl behaves like a mirror, so its focal length is

f = R / 2

f = 44/2

f = 22 cm

a) Suppose that the distance to the object is p = 50 cm, let's find the distance to the image

1 / q = 1 / f - 1 / p

1 / q = 1/22 - 1/50

1 / q = 0.0254

q = 39.29 cm

b) to calculate the size of the image we use the equation of magnification

m = h’/ h = - q / p

h ’= - q / p h

h ’= - 39.29 / 50 5

h ’= - 3.929 cm

the negative sign means that the image is inverted

as the rays of light pass through the image this is REAL

What is the wavelength in nm of a light whose first order bright band forms a diffraction angle of 30 degrees, and the diffracti

Artist 52 [7]

Answer:

The wavelength is 3500 nm.

Explanation:

d= $\frac{1}{700 lines per mm} = 0.007mm = 7000 nm$

n= 1

θ= 30°

λ= unknown

Solution:

d sinθ = nλ

λ = $\frac{7000 nm sin 30}{1}$

λ = 3500 nm

Jeff of the Jungle swings on a 7.6-m vine that initially makes an angle of 32 ∘ with the vertical.

shtirl [24]

To solve this problem we will use the trigonometric concepts to find the distance h, which will allow us to find the speed of Jeff and that will finally be the variable that will indicate the total tension, since it is the variable of the centrifugal Force given in the vine at the lowest poing of the swing.

From the image:

$cos (32) = \frac{(7.6-h)}{7.6}$

$h = 1.1548m$

When Jeff reaches his lowest point his potential energy is converted to kinetic energy

$PE = KE$

$mgh = \frac{1}{2} mv^2$

$v = \sqrt{2gh}$

$v = \sqrt{2(9.8)(1.1548)}$

$v= 4.75m/s$

Tension in the string at the lowest point is sum of weight of Jeff and the his centripetal force

$T = W+F_c$

$T = mg + \frac{mv^2}{r}$

$T = (83)(9.8)+\frac{(9.8)( 4.75)^2}{7.6}$

$T = 842.49N$

Therefore the tension in the vine at the lowest point of the swing is 842.49N
