Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of one's birth. The only known force a planet exerts on Earth is gravitational.
(a) Calculate the magnitude of the gravitational force exerted on a 4.20 kg baby by a 100 kg father 0.200 m away at birth (he is assisting, so he is close to the child).
(b) Calculate the magnitude of the force on the baby due to Jupiter if it is at its closest distance to Earth, some 6.29×10^11 m away. How does the force of Jupiter on the baby compare to the force of the father on the baby?
Other objects in the room and the hospital building also exert similar gravitational forces. (Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.)

Given

m = 24kg

vi = 2 m/s

vf = 6 m/s

Procedure

Impulse = Change in momentum

The answer would be I = 96 kg*m/s

In bright light, the iris constricts and the pupil shrinks to control the amount of light entering the eye.

In bright light, the iris constricts and the pupil shrinks to control the amount of light entering the eye.

The iris is the colored part of the eye surrounding the pupil. It contains muscles that can adjust the size of the pupil. When exposed to bright light, the muscles in the iris contract, causing the pupil to constrict or become smaller in size.

By constricting the pupil, less light is allowed to enter the eye. This helps to protect the sensitive structures within the eye from excessive light intensity, preventing potential damage. It also helps to improve the clarity and sharpness of vision by reducing the amount of light scattering in the eye.

On the other hand, in dim light conditions, the iris relaxes its muscles, allowing the pupil to dilate or expand. This allows more light to enter the eye, maximizing the amount of available light for vision in low-light situations.

So, in bright light, the iris constricts and the pupil shrinks to control the amount of light entering the eye, while in dim light, the iris relaxes and the pupil dilates to allow more light to enter.

The absolute magnitude of Vega is 0.58.

To calculate the absolute magnitude of Vega, follow these steps:

1. Note Vega's apparent magnitude (m) and distance (d): m = 0.03 and d = 7.8 pc.
2. Use the distance modulus formula: M = m - 5 * (log10(d) - 1), where M is the absolute magnitude.
3. Plug in the values: M = 0.03 - 5 * (log10(7.8) - 1).
4. Calculate log10(7.8) ≈ 0.89.
5. Subtract 1 from the logarithm: 0.89 - 1 = -0.11.
6. Multiply by -5: -5 * (-0.11) = 0.55.
7. Add the apparent magnitude: 0.03 + 0.55 = 0.58.

Vega's absolute magnitude is 0.58, which is a measure of its intrinsic brightness if it were at a standard distance of 10 parsecs from Earth.

The wrong statement is that sound waves created vibration Option A.

Sound is a type of waves that moves in compressions and rare factions. This implies that sound is a mechanical wave. Recall that a mechanical wave is one that requires a material medium for propagation. Now we know that if we set the medium into vibration, that is when the sound waves begins to vibrate. That brings us to the idea that it is the vibration that causes the sound waves and not the sound waves that creates the vibration.

Thus, knowing that sound is a mechanical wave which moves through solids liquids and gas and that the vibration of the source of sound is what causes the air to vibrate, we conclude that the wrong statement is that sound waves created vibration Option A.

Too add any two values together you need them to be in the same units. but You can convert diffrent units of the same messure to each other in order to achive this; ie you can add meeters to feet if you multiply the meters by 3.28 but you can't add mass and length together.

With the concept of  pattern we find that the answer for the sum of physical magnitudes is:

They must have the same units when expressed in base units.

To add two phsical quantities to meet some requirements:

* Must be of the same type

* Must be in the same base units

That they have the same type implies that we cannot add length with time or masses, length or speeds must be added with their pairs

The use of the same base unit guarantees that we use the same pattern, or that we must reduce the magnitudes to the same pattern, for example: we cannot add meters with inches directly, we must reduce inches to meters, which is the unit of the international system.

International System  it guarantees the existence of common and reproducible patterns for all physical quantities.

the statement from Dalton's atomic theory that is no longer true is "Atoms are indivisible and cannot be divided into smaller particles."

Dalton's atomic theory, proposed in the early 19th century, stated that atoms were indivisible and indestructible particles, meaning they could not be further divided into smaller particles. However, with advancements in scientific understanding and the development of subatomic particle physics, it has been discovered that atoms are not indivisible. Atoms are composed of subatomic particles, namely protons, neutrons, and electrons. Protons and neutrons reside in the nucleus at the center of the atom, while electrons orbit around the nucleus. Furthermore, scientists have identified even smaller particles within the nucleus, such as quarks and gluons. Hence, the concept of atoms being indivisible, as proposed in Dalton's atomic theory, is no longer valid based on modern atomic theory.

The main cause of the difference in temperature on a daily basis is because of the water surrounding the Florida.

The average thermal energy of the particles in a substance is measured by its temperature. It is a way to express how hot or cold an object is in relation to a reference point, typically a standard temperature scale like Celsius or Fahrenheit. It reflects the heat content of a body.

Florida's proximity to huge bodies of water, which have a moderate impact on the temperature, is mostly to blame for the difference in temperature swings between Florida and a dry desert climate. The water steadily absorbs heat and releases it, lowering temperature swings and fostering a more stable atmosphere. Florida also has a lower altitude than most other states, which helps to stabilize its temperature. Temperatures in Florida are kept warmer in part by the state's increasing sunshine. The larger temperature variations in the desert may also be a result of the shorter daylight hours, as the daytime temperatures can get quite hot and the overnight temperatures can go very low.

The golf ball lost 7/16 of the original kinetic energy in the collision. The correct option is C.

Step 1: Find the final speed after the collision. The ball bounces back at 3/4 the original speed.

Step 2: Calculate the initial and final kinetic energy. Kinetic energy (KE) \(= 1/2 * mass (m) * velocity^2 (v^2)\). Since we're comparing the same golf ball, the mass will be the same in both calculations, so we can focus on the velocity squared.

Step 3: Find the ratio of the final kinetic energy to the initial kinetic energy. (Final KE) / (Initial KE) = (3/4 * v)^2 / (v^2) = 9/16.

Step 4: Calculate the proportion of the original kinetic energy lost. This is equal to 1 - (Final KE / Initial KE) = 1 - 9/16 = 7/16.

So, the golf ball lost 7/16 of the original kinetic energy in the collision, which is option (c).

To determine the constant angular acceleration and the time required for the flywheel to achieve an angular velocity of w=10 rad/s, starting from rest, we can use the following formula:

ω = ω₀ + αt

Where:
- ω is the final angular velocity (10 rad/s)
- ω₀ is the initial angular velocity (0 rad/s since the flywheel starts from rest)
- α is the constant angular acceleration we are trying to find
- t is the time required to reach the final angular velocity

We know that the flywheel rotates 20 revolutions, which means it covers a total angle of 20 * 2π radians (since 1 revolution = 2π radians).

Using the formula for angular displacement:

θ = ω₀t + 0.5αt²

Where:
- θ is the total angular displacement (20 * 2π radians)
- ω₀ is the initial angular velocity (0 rad/s)
- α is the constant angular acceleration we are trying to find
- t is the time required to reach the final angular velocity

Substituting the values into the equation, we get:

20 * 2π = 0.5αt²

Simplifying, we have:

40π = αt²

We also know that the final angular velocity is related to the angular acceleration and time by:

ω = αt

Substituting the given value, we have:

10 = αt

Now we have a system of two equations:

40π = αt²
10 = αt

From the second equation, we can solve for α in terms of t:

α = 10/t

Substituting this value of α into the first equation, we get:

40π = (10/t) * t²

Simplifying further:

40π = 10t

Solving for t:

t = (40π) / 10
t = 4π

So, the time required for the flywheel to achieve an angular velocity of 10 rad/s is 4π seconds.

Now, let's find the constant angular acceleration:

α = 10 / t
α = 10 / (4π)
α = 2.53 rad/s²

Therefore, the constant angular acceleration is approximately 2.53 rad/s².


To determine the constant angular acceleration and the time required for the flywheel to achieve an angular velocity of w=10 rad/s, starting from rest, we can use the formulas relating angular velocity, angular acceleration, and time.

The flywheel rotates 20 revolutions, which is equivalent to 20 * 2π radians of total angular displacement. We can use the formula for angular displacement to relate this value to the initial angular velocity, constant angular acceleration, and time.

By substituting the given values into the formula, we get the equation 20 * 2π = 0.5αt².

Simplifying further, we have 40π = αt².

We also know that the final angular velocity is related to the angular acceleration and time by the equation ω = αt.

By substituting the given value of ω=10 rad/s,

we have 10 = αt.

Now, we have a system of two equations: 40π = αt² and

10 = αt.

By solving for α in terms of t from the second equation, we get α = 10/t.

Substituting this value of α into the first equation, we get 40π = (10/t) * t².

Simplifying further, we have 40π = 10t.

Solving for t, we get t = (40π) / 10

= 4π seconds.

Therefore, the time required for the flywheel to achieve an angular velocity of 10 rad/s is 4π seconds.

To find the constant angular acceleration, we substitute the value of t back into α = 10 / t,

giving us α = 10 / (4π)

≈ 2.53 rad/s².

The constant angular acceleration is approximately 2.53 rad/s², and the time required for the flywheel to achieve an angular velocity of 10 rad/s is 4π seconds.
