A ray in glass arrives at the glass-water interface at an angle of 48° with the normal. The refracted ray, in water, makes a 72°

angle with the normal. The index of refraction of water is 1.33. Then the ray in glass is redirected so its new angle of incidence is 37°. What is the new angle of refraction in the water? Show all work.

Answer:

50.4°

Explanation:

Snell's law states:

n₁ sin θ₁ = n₂ sin θ₂

where n is the index of refraction and θ is the angle of incidence (relative to the normal).

When θ₁ = 48°:

n sin 48° = 1.33 sin 72°

n = 1.702

When θ₁ = 37°:

1.702 sin 37° = 1.33 sin θ

θ = 50.4°

A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of 80.6 m/s at ground level.
bezimeni [28]

solution:

y = v0t + ½at²

1150 = 79t + ½3.9t²

0 = 3.9t² + 158t - 2300

from quadratic equations and eliminating the negative answer

t = (-158 + v158² -4(3.9)(-2300)) / 2(3.9)

t = 11.37 s to engine cut-off

the velocity at that time is

v = v0 + at

v = 79 + 3.9(11.37)

v = 123.3 m/s

it rises for an additional time

v = gt

t = v/g

t = 123.3 / 9.8

t = 12.59 s

gaining more altitude

y = ½vt

y = 123.3(12.59) /2

y = 776 m

for a peak height of

y = 776 + 1150

A block of wood measuring 2.75 cm x 4.80 cm x 7.50 cm has a mass of 84.0 g. will the block of wood sink or float in water?
KIM [24]
The volume of the block of wood is given by length × width ×height
 = 2.75 × 4.80 × 7.5
 = 99 cm³
Density is given by mass/volume
Thus = 84.0 g/ 99 cm³
         = 0.848 g/cm³
Hence;  since the block is less dense than water (1 g/cm³) it will float

Water from Old Faithful Geyser shoots upward to a height of about 50 m once every 90 minutes. What must be the pressure in the h
Naya [18.7K]

Solution:

Given:

height of geyser, h = 50 m

speed of water at ground can be given by third eqn of motion with v = 0 m/s:

u^{2} = v^{2} + 2gh

putting v = 0 m/s in the above eqn, we get:

u = \sqrt{2gh}                      (1)

Now, pressure is given by:

\Delta p = \frac{1}{2}u^{2}\rho \\        (2)

where,

\Delta p = density of water = 1000 kg/m^{3}

g = 9.8 m/s^{2}

Using eqn (1) and (2):

\Delta p = \frac{1}{2}(\sqrt{2gh})^{2}\rho

⇒ \Delta p = \frac{1}{2}\rho gh

\Delta p = \frac{1}{2}\times2\times 1000\times 9.8\times 50 = \Delta p =   490000 Pa

p_{atm} = 101325 Pa

For absolute pressure, p:

p = \Delta p + p_{atm}

p = 490000 - 101325

p = 388675 Pa

Therefore, pressure in hot springs for the water to attain the height of 50m is 388675 Pa
