A multi-dimensional being reaches down to Earth and pulls you out of the universe. You are then thrown back into the universe at a place and time of the being's choosing, and you are permitted to leave only after you have identified your surroundings. This process is repeated several times. Through a scientifically unexplainable miracle, you are able to survive in every one of the places that you find yourself. In each scenario below, identify your surroundings (and potentially your cosmic era) from among the choices given. You find yourself in a place that is unimaginably hot and dense. A rapidly changing gravitational field randomly warps space and time. Gripped by these huge fluctuations, you notice that there is but a single, unified force governing the universe.

Answer and explanation: Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

3. A 75 kg linebacker moving at 6 m/s is running towards an 80 kg tackle moving 4 m/s. If they collide and stick together, how fast will they be moving after the collision?

5. A 6 kg bowling ball and a 4 kg bowling ball are rolled toward each other. The 6 kg ball is initially moving at 5.1 m/s and the 4 kg ball is moving in the opposite direction at 1.3 m/s. If the 6 kg ball slows to 1.5 m/s, what is the final speed of the 4 kg ball?

3. The sum of the players' momenta is equal to the momentum of the players when they're stuck together:

(75 kg) (6 m/s) + (80 kg) (-4 m/s) = (75 kg + 80 kg) v

where v is the velocity of the combined players. Solve for v :

450 kg•m/s - 320 kg•m/s = (155 kg) v

v = (130 kg•m/s) / (155 kg)

**v ≈ 0.84 m/s**

4. The total momentum of the bowling balls prior to collision is conserved and is the same after their collision, so that

(6 kg) (5.1 m/s) + (4 kg) (-1.3 m/s) = (6 kg) (1.5 m/s) + (4 kg) v

where v is the new velocity of the 4-kg ball. Solve for v :

30.6 kg•m/s - 5.2 kg•m/s = 9 kg•m/s + (4 kg) v

v = (16.4 kg•m/s) / (4 kg)

**v = 4.1 m/s**

define Newton's law of motion

By definition, **Newton's First Law**, also called the Law of inertia, indicates that "Every body perseveres in its** state of rest or of uniform rectilinear motion** **unless it is forced to change **its state by forces impressed on it."

This means that for a body to come out of its state of rest or of uniform rectilinear motion, it is necessary for a force to act on it.

Definition of inertiaSo,** in other words**, all bodies are opposed to changing their state of rest or motion and this opposition is called** inertia**.

In this way, a body is in** equilibrium** when the resultant of the **forces acting** on it is **zero**. That is, it is not possible for a body to change its initial state (be it rest or motion) unless one or more forces intervene.

a new planet is discovered that has twice the earth’s mass and twice the earth’s radius. on the surface of this new planet, a person who weighs 500 n on earth would experience a gravitational force of

**Answer: 250n**

**Explanation: **

The formula for gravitational force is: **F = (gMm)/r^2**

There are two factors at play here:

**1) The mass of the planet 'M'**

**2) The radius 'r'**

We can ignore the small M and the g, they are constants that do not alter the outcome of this question.

You can see that both M and r are double that of earth. So lets say earth has M=1 and r=1. Then, new planet would have M=2 and r=2. Let's sub these two sets into the equation:

Earth. F = M/r^2 = **1/1 **

New planet. F = M/r^2 = 2/4 =** 1/2**

So you can see that the force on the new planet is half of that felt on Earth.

The question tells us that the force on earth is 500n for this person, so then on the new planet it would be half! **So, 250n! **

Why does the size of a white dwarf affect its visual luminosity?

**Answer:**

A typical white dwarf has a carbon and oxygen mass similar to the Sun, but is much smaller in size (similar to the Earth). It is much hotter (25,000 K), but because of its small size its luminosity is low. ... Some very nearby white dwarf stars can be observed directly through telescopes, though they are extremely faint.

Explain why stationary waves are seen only certain frequencies (3 marks)

**Explanation:**

The underlying physics give rise to periodic behavior. Usually, some resonance is involved, in which the media damps waves except those at a specific frequency.

__

Only waves at a specific frequency are recognized as being "stationary." If the frequency varies, the behavior is described as "chaotic." So, it's partly a matter of definition.

If astronomers discovered a new planet and found its period of rotation around the Sun to be 105 years, how long would its semi-major axis length be as it orbited the Sun in AU?

From **Kepler's third law**, its semi-major axis length will be **22.2 AU** approximately as it orbited the Sun in AU. The closest option is option **C**

Given that an astronomers discovered a new planet and found its period of rotation around the Sun to be 105 years.

According to **Kepler's third law**,

[tex]T^{2} \alpha r^{3}[/tex]

Where

T = Period ( in earth years) = time to complete one orbit

r = Length of the semi major axis in Astronomical unit.

[tex]T^{2}[/tex] = [tex]\frac{4\pi ^{2} }{GM} * r^{3}[/tex]

1.096 x [tex]10^{19}[/tex] = 2.976 x [tex]10^{-19}[/tex] [tex]r^{3}[/tex]

[tex]r^{3}[/tex] = 1.096 x [tex]10^{19}[/tex] / 2.976 x [tex]10^{-19}[/tex]

**Explanation:**

Not only is the above an unnecessarily complicated answer, it's not even fully correct, and definitely not what they want you to do.

*T*^2 = *s*^3, where *T* = orbital period and *s* = semi-major axis length.

Substitute *T *and you get 105^2 = *s*^3. Solve for *s*.

3√11025 = *s*

An object accelerates from rest to 93 m/s over a distance of 49 m. What acceleration did it experience?

**Answer:**

[tex]88.3ms {}^{ - 2} [/tex]

or 88.3m/s^2

**Explanation:**

Using suvat where we list everything that we are given

s=49m

u=0m/s

v=93m/s

a=?

t=we are not given this value, so we don't use

using a formula that doesn't involve time:

[tex]v {}^{2} = u {}^{2} + 2as[/tex]

rearranging to find acceleration by subtracting u^2 on both sides

[tex]v {}^{2} - u {}^{2} = 2as[/tex]

then dividing 2s on both sides

[tex] \frac{v {}^{2} - u {}^{2} }{2s} = a[/tex]

[tex] \frac{(93) {}^{2} - (0) {}^{2} }{2 \times(49) } = 88.3ms {}^{ - 2} [/tex]

so the acceleration is 88.3ms^-2 (1dp)

Answer: Asteroid 1 has more mass than asteroid 2

Explanation:

We can use the conservation of momentum law to find the answer. So, according to this law:

"If two objects or bodies are in a closed system and both collide, the total momentum of these two objects before the collision will be the same as the total momentum of these same two objects after the collision".

This means the momentum before the collision or crash () is equal to the momentum after the collision ():

(1)

Before the crash:

(2)

Where:

is the mass of the first asteroid

is the velocity of the first asteroid

is the mass of the second asteroid

is the velocity of the second asteroid

(3)

After the crash:

(4)

Where:

is the final velocity of the first asteroid

is the final velocity of the second asteroid

(5)

Substituting (3) and (5) in (1):

(6)

Grouping similar terms:

(7)

Then:

(8) This means must be multiplied by 1.16 km/s in order to make this side of the equation equal to .

Which of the following is true for gravitational force?

Group of answer choices

Decreases with decrease in distance

Increases with increase in distance

Decreases with increase in mass

Increases with increase in mass

**Answer:**

The gravitational force b) Increases with increase in mass.

Explanation:

The gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}F=Gr2m1m2

where

G is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between the objects

From the equation, we notice that:

- The force is proportional to the masses, m1 and m2: so, if the masses increase, the force will increase, and if the masses decrease, the force will decrease

- The force is inversely proportional to the distance between the masses, r: so, if the distance increases, the force will decreases, and if the distance decreases , the force will increases

Therefore, the correct options is only:

Increases with increase in mass

**Answer: The answer is b increases in increase of mass because the heavier the object is the more gravitional pull it will have.**
