If the lens of our eyes were concave, we would not be able to see. We would be blind. This is because our eyes form a visual image on the same side of the lens at the object being viewed. Thus, a concave lens would result in the visual image focusing in front of the eye, not the retina inside the eye. This would mean that no signals would be sent to the brain, and vision would not be possible.

The statement "All Motion is relative to a reference point." is True.

An inertial frame of reference is a frame of reference in which the Newton's laws are valid. In this frame of reference, the objects do not accelerate without any external force. All frames of reference moving with constant velocity are considered stationary.

In a non-inertial frame of reference, the Newton's laws will not work. They are moving with an acceleration.

Answer:

The final translational seed at the bottom of the ramp is approximately 4.84 m/s

Explanation:

The given parameters are;

The radius of the sphere, R = 2.50 cm

The mass of the sphere, m = 4.75 kg

The translational speed at the top of the inclined plane, v = 3.00 m/s

The length of the inclined plane, l = 2.75 m

The angle at which the plane is tilted, θ = 22.0°

We have;

\(K_i\) + \(U_i\) = \(K_f\) + \(U_f\)

K = (1/2)×m×v²×(1 + I/(m·r²))

I = (2/5)·m·r²

K =  (1/2)×m×v²×(1 + 2/5) = 7/10 × m×v²

U = m·g·h

h = l×sin(θ)

h = 2.75×sin(22.0°)

∴ 7/10×4.75×3.00² + 4.75×9.81×2.75×sin(22.0°) = 7/10 × 4.75×\(v_f\)² + 0

7/10×4.75×3.00² + 4.75×9.81×2.75×sin(22.0°) ≈ 77.93

∴ 77.93 ≈ 7/10 × 4.75×\(v_f\)²

\(v_f\)² = 77.93/(7/10 × 4.75)

\(v_f\) ≈ √(77.93/(7/10 × 4.75)) ≈ 4.84

The final translational seed at the bottom of the ramp, \(v_f\) ≈ 4.84 m/s.

The process that is the source of all the thermal energy produced by a nuclear reactor is nuclear fission. The correct option is C.

The process by which an atom's nucleus divides into two daughter nuclei in nuclear physics. Fission, the splitting of uranium atoms, is the source of nuclear energy.

This produces heat that creates steam, which a turbine generator uses to produce power. A type of energy emitted by an atom's nucleus, which is composed of protons and neutrons, is known as nuclear energy.

Fission, which occurs when atom nuclei split into several pieces, and fusion, which occurs when nuclei combine, are the two methods by which this type of energy can be created.

Therefore, the correct option is C. Nuclear fission.

In the given scenario, Event A occurs at the spacetime origin in both frames S and S'. Event B occurs at coordinates (xe, ye, ze, ct) in frame S and coordinates (x', y', z', ct') in frame S'. The task is to determine the time of occurrence of Event B in frame S' and the relative velocity between frames S and S'.

According to the Lorentz transformation equations, the relationship between the coordinates of an event in frame S and frame S' can be expressed as:

x' = γ(x - vt)

y' = y

z' = z

ct' = γ(ct - vx/c^2)

Given the coordinates of Event B in frame S as (xe = 2, ye = 0, ze = 0, ct = -3) and the relative velocity between frames S and S' as v = 0.290c, we can substitute these values into the Lorentz transformation equations to determine the coordinates of Event B in frame S'.

By plugging the values into the equations, we find that x' = 3.74m/c, y' = 0, z' = 0, and ct' = -3. By considering the relationship (ct)' = (x')^2 + (y')^2 + (z')^2, we can conclude that Event B occurs at time t' = -3.74m/c in frame S'.

Furthermore, the relative velocity between frames S and S' is given as v = 0.290c, indicating that frame S' is moving at a speed of 0.290 times the speed of light relative to frame S.

Therefore, the time of occurrence of Event B in frame S' is 3.74m/c and the relative velocity between frames S and S' is v = 0.290c.

The time taken to increase the speed of the train from rest to 78.0 km/h is 6.8 mins

We'll begin by obtaining the impulse of the sytem. This is shown below:

Impulse = final momentum – Initial momentum

Impule = m(v - u)

Impulse = 1.30×10⁷ × (21.67 - 0)

Impulse = 1.30×10⁷ × 21.67

Impulse = 281710000 Ns

Finally, we shall determine the time taken. This is shown below:

Impulse = force × time

281710000 = 6.90×10⁵ × time

Divide both sides by 6.90×10⁵

Average force = 281710000 / 6.90×10⁵

Time = 408.28 s

Divide by 60 to excess in minutes

Time = 408.28 / 60

Time = 6.8 mins

Explanation:

When Two Samples of Water are Mixed, what Final Temperature Results?

Go to Mixing Two Amounts of Water: Problems 1 - 10

Go to calculating the final temperature when mixing water and a piece of metal

Worksheet #2

Back to Thermochemistry Menu

Example #1: Determine the final temperature when 32.2 g of water at 14.9 °C mixes with 32.2 grams of water at 46.8 °C.

This is problem 8a from Worksheet #2.

First some discussion, then the solution. Forgive me if the points seem obvious:

1) The colder water will warm up (heat energy "flows" into it). The warmer water will cool down (heat energy "flows" out of it).

2) The whole mixture will wind up at the SAME temperature. This is very, very important.

3) The energy which "flowed" out (of the warmer water) equals the energy which "flowed" in (to the colder water)

This problem type becomes slightly harder if a phase change is involved. For this example, no phase change. What that means is that only the specific heat equation will be involved

Solution Key Number One: We start by calling the final, ending temperature 'x.' Keep in mind that BOTH water samples will wind up at the temperature we are calling 'x.' Also, make sure you understand that the 'x' we are using IS NOT the Δt, but the FINAL temperature. This is what we are solving for.

The warmer water goes down from to 46.8 to x, so this means its Δt equals 46.8 − x. The colder water goes up in temperature, so its Δt equals x − 14.9.

That last paragraph may be a bit confusing, so let's compare it to a number line:



To compute the absolute distance, it's the larger value minus the smaller value, so 46.8 to x is 46.8 − x and the distance from x to 14.9 is x − 14.9.

These two distances on the number line represent our two Δt values:

a) the Δt of the warmer water is 46.8 minus x

b) the Δt of the cooler water is x minus 14.9

Solution Key Number Two: the energy amount going out of the warm water is equal to the energy amount going into the cool water. This means:

qlost = qgain

However:

q = (mass) (Δt) (Cp)

So:

(mass) (Δt) (Cp) = (mass) (Δt) (Cp)

With qlost on the left side and qgain on the right side.

Substituting values into the above, we then have:

(32.2) (46.8 − x)(4.184) = (32.2) (x − 14.9) (4.184)

Solve for x

Cyclotron to make 1 milligram of the isotope fluorine-18 for use a a diagnostic tool with it PET scanner. It seems that the hospital should plan to make more F-18 the next morning, as the amount remaining at midnight is very small.

The half-life of F-18 is 1.8 hours, so after 1.8 hours, half of the original amount of F-18 will remain. After 3.6 hours, a quarter of the original amount will remain, and so on.

At 3:00 PM (9 hours after the F-18 was made), the hospital will have

= 1/2^(9/1.8)

= 1/2^5

= 1/32

= approximately 0.03125 milligrams of F-18 remaining.

At midnight (18 hours after the F-18 was made), the hospital will have

= 1/2^(18/1.8)

= 1/2^10

= 1/1024

= approximately 0.0009765625 milligrams of F-18 remaining.

Explanation:

Initial Velocity(U)=9.5m/s

Maximum Horizontal Distance (i.e maximum height) = ?

V^2=U^2-2gH (negative because the motion is against gravity i.e g is negative)

0^2=9.5^2-(2×10×H)

0=90.25-20H

20H=90.25

H=90.25/20=4.5125m

Therefore, the minimum speed at which the roller coaster can make a vertical loop with a radius of 44 m while the dummy stays in its seat is approximately 20.8 m/s.

To find the minimum speed at which the roller coaster can make a vertical loop with a radius of 44 m while the dummy stays in its seat, we can use the concept of centripetal force.
In a vertical loop, the force of gravity acting on the dummy must be greater than the force exerted by the seat on the dummy to prevent it from falling out.
The force of gravity acting on the dummy can be calculated using the formula F = mg, where m is the mass of the dummy (20 kg) and g is the acceleration due to gravity (9.8 m/s^2).
The force exerted by the seat can be calculated using the formula F = m * (v^2 / r), where v is the velocity of the roller coaster and r is the radius of the loop (44 m).
For the dummy to stay in its seat, the force of gravity must be greater than or equal to the force exerted by the seat.
Setting these two forces equal, we can solve for the velocity (v).
Using the formula: mg = m * (v^2 / r)
Plugging in the values: 20 kg * 9.8 m/s^2 = 20 kg * (v^2 / 44 m)
Simplifying the equation: 9.8 m/s^2 = v^2 / 44 m
Solving for v: v^2 = 9.8 m/s^2 * 44 m
v^2 = 431.2 m^2/s^2
Taking the square root of both sides, we get: v ≈ 20.8 m/s
Therefore, the minimum speed at which the roller coaster can make a vertical loop with a radius of 44 m while the dummy stays in its seat is approximately 20.8 m/s.

(a) μ = 0

The heavier block will accelerate to the right with an acceleration of:

a = F / m = k x / m = (3.70 N/m) (0.0864 m) / 0.261 kg = 1.22 m/s²

The lighter block will also accelerate to the right with an acceleration of 1.22 m/s².

(b) μ = 0.110

The heavier block will accelerate to the right with an acceleration of:

a = F - μk / m = k x / m - μk / m = (3.70 N/m) (0.0864 m) / 0.261 kg - (0.110)(0.261 kg)(9.80 m/s²) = 0.68 m/s²

The lighter block will not accelerate because the force of friction is greater than the force of the spring.

(c) μ = 0.480

The heavier block will accelerate to the right with an acceleration of:

a = F - μk / m = k x / m - μk / m = (3.70 N/m)(0.0864 m) / 0.261 kg - (0.480)(0.261 kg) (9.80 m/s²) = -0.82 m/s²
