A diver shines a light up to the surface of a flat glass-bottomed boat at an angle of 37◦ relative to the normal. If the indices of refraction of air, water, and glass are 1.0, 1.33, and 1.4 respectively, at what angle does the light leave the glass (relative to its normal)? Answer in units of ◦ .
Answers
Answer:
Approximately \(53^{\circ}\), assuming that the upper and lower surfaces of the glass on this boat are parallel.
Explanation:
Assume that the upper and lower surfaces of the glass at the bottom of this ship are parallel. Refer to the diagram attached. The two normals would also be parallel to each other.
The following angles would be alternate interior angles between the two normals:
The angle at which the light enters the glass, andThe angle at which the light leaves the glass.Since the two normals are parallel to each other, these two angles would have the same value. Let \(\theta_{\text{glass}}\) denote the value of both of these angles.
Let \(\theta_{\text{src}}\) denotes the angle at which a beam of light leaves the original medium (angle of incidence.) Let \(\theta_{\text{dst}}\) denote the angle at which this beam of light enters the new medium.
Let \(n_\text{src}\) and \(n_\text{dst}\) denote the refractive indices of the original and the new medium, respectively. By Snell's Law:
\(\begin{aligned}\frac{\sin(\theta_{\text{dst}})}{\sin(\theta_{\text{src}})} = \frac{n_{\text{src}}}{n_{\text{dst}}}\end{aligned}\).
Let \(\theta_{\text{water}}\) denote the angle at which the beam of light in this question leaves the water. Let \(\theta_{\text{air}}\) denote the angle at which this beam of light enters the air. It is given that \(\theta_{\text{water}} = 37^{\circ}\), while \(\theta_{\text{air}}\) is the value that needs to be found.
Let \(n_{\text{air}}\), \(n_{\text{water}}\), and \(n_{\text{glass}}\) denote the refractive index of air, water, and glass, respectively. By Snell's Law:
\(\begin{aligned}\frac{\sin(\theta_{\text{glass}})}{\sin(\theta_{\text{water}})} = \frac{n_{\text{water}}}{n_{\text{glass}}}\end{aligned}\).
\(\begin{aligned}\frac{\sin(\theta_{\text{air}})}{\sin(\theta_{\text{glass}})} = \frac{n_{\text{glass}}}{n_{\text{air}}}\end{aligned}\).
Thus:
\(\begin{aligned} & \frac{\sin(\theta_{\text{air}})}{\sin(\theta_{\text{water}})} \\ =\; & \frac{\sin(\theta_{\text{glass}})}{\sin(\theta_{\text{water}})}\times \frac{\sin(\theta_{\text{air}})}{\sin(\theta_{\text{glass}})} \\ =\; & \frac{n_{\text{water}}}{n_{\text{glass}}}\times \frac{n_{\text{glass}}}{n_{\text{air}}} \\ =\; & \frac{n_{\text{water}}}{n_{\text{air}}}\end{aligned}\).
Since \(\theta_{\text{water}} = 37^{\circ}\):
\(\begin{aligned} & \sin(\theta_{\text{air}})\\ =\; & \sin(\theta_{\text{water}}) \times \frac{\sin(\theta_{\text{air}})}{\sin(\theta_{\text{water}})} \\ =\; & \sin(\theta_{\text{water}})\times \frac{n_{\text{water}}}{n_{\text{air}}} \\ =\; & \sin(37^{\circ}) \times \frac{1.33}{1.0} \\ \approx \; & 0.800 \end{aligned}\).
Therefore:
\(\begin{aligned}\theta_{\text{air}} &= \arcsin(\sin(\theta_{\text{air}})) \\ & \approx \arcsin(0.800) \\ &\approx 53^{\circ} \end{aligned}\).
In other words, this beam of light would leave the glass at approximately \(53^{\cic}\) from the normal.

Answers
Answer:
E_{total} = -1.13 10² N / C
the sign indicates that the electric field points to the left
Explanation:
Let's start this exercise by looking for the electric field created by an infinite leaf, for this let's use Gauss's law
\(\Phi_E\) = ∫ E. dA = \(q_{int}\) /ε₀
Let's define a Gaussian surface that is a cylinder, the normal to the faces of the cylinder is parallel to the field created by the face inside the surface, the normal of the cylinder walls is perpendicular to the electric field so its scalar product is zero
\Phi_E = E (2A) = q_{int} /ε₀
the number 2 is due to having two faces
E = \(\frac{q_{int} }{A} \ \frac{1}{2 \epsilon_0 }\)
the surface charge density is
σ= Q / A
we substitute
E = \(\frac{\sigma }{2 \epsilon_o}\)
we can see that the field is independent of the distance.
Let's write the field for each leaf, remember that the field is salient for positive charges
sheet 1
E₁ = \(+ \frac{\sigma_1}{2 \epsilon_o}\)
sheet 2
E₂ = \(- \frac{\sigma_2}{2 \epsilon_o}\)
sheet 3
E₃ = \(+ \frac{\sigma_3}{2 \epsilon_o}\)
at the point the Field of sheet 1 points to the right,
the field on sheet 2 points to the left and the field on sheet 3 points to the left. Tthe electric field at the midpoint is
E_ {total} = E₁ - E₂ - E₃
E_ {total} = \(\frac{1}{2 \epsilon_o}\) (σ₁ - σ₂ -σ₃)
calculate
E_total = \(\frac{1}{2 \ 8.85 \ 10^{-12}}\) (8.00 -4.00 -6.00) 10⁻⁹
E_total = -1.13 10² N / C

Answers
Answer:
M = 5.882 10²³ kg
Explanation:
Let's use Newton's second law to analyze the satellite orbit around Mars.
F = m a
force is universal attraction and acceleration is centripetal
a = v²/ R
the modulus of velocity in a circular orbit is constant
v= d/T
the distance of the cicule is
d =2pi R
a = 2pi R/T
we substitute
- G m M / R² = m ( \(- \frac{4\pi^2 R^2 }{T^2 R}\))
G M = \(\frac{ 4\pi ^2 R^3 }{T^2 }\)
M = \(\frac{4 \pi ^2 R^3 }{ G T^2 }\)
the distance R is the distance from the center of the planet Mars to the center of the satellite Deimos
R = 23460 km = 2.3460 10⁷ m
the period of the orbit is
T = 1,263 days = 1,263 day (24 h / 1 day) (3600s / h)
T = 1.0912 10⁵ s
let's calculate
M = \(\frac{4 \pi ^2 ( 2.3460 \ 10^7)^3 }{5.67 10^{-11} \ (1.0912 \ 10^5)^2 }\)
M = 509.73418 10²¹ /8.66640 10⁻¹
M = 58.817 10²² kg
M = 5.882 10²³ kg

what differentiates between static and dynamic charge
Answers
Static charge refers to an electric charge that is stationary or at rest on an object. This type of charge is typically caused by the transfer of electrons between two objects, resulting in an imbalance of electric charge. When two objects are in contact, electrons can move from one object to another, creating a static charge on one or both objects. The charge remains in place until it is discharged, either through a spark, a sudden movement of electrons, or through contact with a grounded object.
Dynamic charge, on the other hand, refers to an electric charge that is in motion or flowing. This is the type of charge that is used to power electrical devices, such as batteries or generators. In a dynamic charge system, electrons move through a circuit, generating a flow of electrical current that can be harnessed to power machines or devices.
In summary, the main difference between static and dynamic charge is that static charge is stationary or at rest, while dynamic charge is in motion or flowing through a circuit.

Answers
Answer:
Maximum height = 2040 m
Explanation:
We can solve the problem using kinematics.
Consider the vertical motion of the object and use the equation:
\(\boxed{v^2 = u^2 + 2as}\)
where:
• v = final velocity (0 m/s, because when the object is at max. height, it has no vertical velocity)
• u = initial velocity (400sin30° m/s ⇒ vertical component of 400 m/s at 30° to horizontal)
• a = acceleration (-9.81 m/s²; considering upward acceleration to be negative)
• s = displacement (? m; this represents the max. height of the object),
Substitute the values into the equation and solve for s :
\(0^2 = (400 sin (30 \textdegree))^2 + 2(-9.81)(s)\)
⇒ \(2(9.81)(s) = (400 sin (30 \textdegree))^2\)
⇒ \(s = 2040 \space\ m\) (3 s.f.)

Alcohol of mass 33.2g and density 0.79kg/m³ or 790kg/m³ is mixed with water of 9g. What is the density of the resulting mixture?.
Answers
Answer:
0.83 g/cm³
Explanation:
The volume of the alcohol is ...
(33.2 g)/(0.79 g/cm³) ≈ 42.0253 cm³
The density of water is about 1 g/cm³, so the volume of 9 g of it is ...
(9 g)/(1 g/cm³) = 9 cm³
The total volume is ...
42.0253 cm³ +9 cm³ = 51.0253 cm³
The total mass is ...
33.2 g + 9 g = 42.4 g
So, the resulting density is ...
(42.4 g)/(51.0253 cm³) ≈ 0.83 g/cm³
The resulting mixture has a density of about 0.83 g/cm³.
_____
Additional comment
Alcohol dissolves in water, so the total volume will be slightly less than 51.0253 cm³. The attached curve shows the result of mixing ethanol and water.
The weight of a mole of ethanol is about 46 g, of water, about 18.02 g. Then the mole fraction of alcohol is ...
(33.2/46)/(33.2/46 +9/18.02) ≈ 0.59
The volume of the mix is then estimated to be (-1.05 cc/mol)(1.221 mol), or about 1.28 cm³ less than the volume indicated above. That brings the density up to about 0.85 g/cm³.
We're not completely sure of the relevance of this calculation, since many of the applicable parameters are not specified. The point is that the density of the mix will probably be slightly more than the value calculated above. YMMV

first resolve the initial velocity of the ball into two components

call the initial velocity=p=25.4 m/s at 58.0° deg to ground
so the horizontal component of velocity=25.4cos58=13.46 m/s
so the vertical component of velocity=25.4sin58=21.54 m/s
we have nothing to do with the horizontal component of velocity as it plays no part in the hang time
only vertical component of velocity determines the hang time
hang time=2*(vertical component of velocity)/(acceleration due to gravity)
==>hang time=2*21.54/9.8=4.39 s
==>hang time =4.39 s

what is the full distance when an object is thrown at 35 m/s at an angle of 45 degrees
Answers
Okay, here are the steps to calculate the full distance traveled when an object is thrown at a certain speed and angle:
You have the initial velocity (v): 35 m/s
You have the launch angle (θ): 45 degrees
We need to split the initial velocity into its horizontal (vx) and vertical (vy) components.
To calculate vx (horizontal component):
vx = v * cosθ
vx = 35 * cos(45) = 24.7 m/s
To calculate vy (vertical component):
vy = v * sinθ
vy = 35 * sin(45) = 24.7 m/s
We can calculate the horizontal distance (d) traveled using:
d = vx * t (where t is time)
Since there is no air resistance, the vertical velocity (vy) will remain constant. This means the time the object is in the air is:
t = vy / g (where g is acceleration due to gravity, 9.8 m/s^2)
t = 24.7 / 9.8 = 2.52 seconds
Now we can calculate the full horizontal distance traveled:
d = vx * t
d = 24.7 * 2.52
= 62.3 meters
So the full distance the object will travel when thrown at 35 m/s at a 45 degree angle is approximately 62 meters.
Let me know if you have any other questions!
Answer:
To calculate the full distance traveled by an object thrown at a velocity of 35 m/s at an angle of 45 degrees, we need to consider the horizontal and vertical components of the motion separately.
The horizontal component of the motion remains constant throughout the trajectory and is given by:
Horizontal distance = (Initial velocity) * (Time of flight) * cos(angle)
In this case, the initial velocity is 35 m/s, the angle is 45 degrees, and we need to find the time of flight.
The time of flight can be calculated using the vertical component of the motion. The vertical motion can be described using the equation:
Vertical displacement = (Initial velocity * sin(angle))^2 / (2 * acceleration)
Where the initial velocity is 35 m/s, the angle is 45 degrees, and the acceleration is the acceleration due to gravity, approximately 9.8 m/s^2.
The vertical displacement is zero at the highest point of the trajectory since the object comes back down to the same height it was launched from. So we can solve the equation for the time of flight.
Using these calculations, we can find the horizontal distance traveled by the object.
Let's calculate step by step:
Step 1: Calculate the time of flight
Vertical displacement = 0 (at the highest point)
0 = (35 * sin(45))^2 / (2 * 9.8)
0 = (24.75^2) / 19.6
0 = 616.0125 / 19.6
0 = 31.43
Step 2: Calculate the time of flight
Vertical displacement = (Initial velocity * sin(angle)) * time - (1/2) * acceleration * time^2
0 = (35 * sin(45)) * time - (1/2) * 9.8 * time^2
0 = 24.75 * time - 4.9 * time^2
4.9 * time^2 - 24.75 * time = 0
time * (4.9 * time - 24.75) = 0
time = 0 (initial point) or 24.75 / 4.9
time = 5.05 seconds
Step 3: Calculate the horizontal distance
Horizontal distance = (Initial velocity) * (Time of flight) * cos(angle)
Horizontal distance = 35 * 5.05 * cos(45)
Horizontal distance = 35 * 5.05 * (sqrt(2)/2)
Horizontal distance = 88.96 meters
Therefore, when an object is thrown at 35 m/s at an angle of 45 degrees, the full distance traveled is approximately 88.96 meters.What is the force of gravity (in newtons) acting between the earth and a 5 kg bowling ball that is resting on the surface of the earth
