**Answer: The answer to 3 to is less inertia. The answer to 4 is large amount of inertia. The answer to 5 is large amount of inertia. The answer to 6 is more fuel. Number 6 is kind of unkown considering I can’t see the other answer but I guess it’s more fuel.**

**Explanation: Inertia is the resistance of the object to any change in its motion, including a change in direction. An object will stay still or keep moving at the same speed and in a straight line, unless it is acted upon by an external unbalanced force. So when there is more inertia, it’s harder to control, but when it has less inertia, it’s more loose and easier to move around.**

If all objects that have mass also have gravity, why doesn't your pencil get pulled towards you while it sits on your desk?

**Answer:**

The pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.

**Explanation:**

Let us apply Newton's Law of Gravitation between a person and pencil.

Average Mass of a Normal Pencil = m₁ = 10 g = 0.01 kg

Average Mass of a Person = m₂ = 80 kg

Distance between both = r = 1 cm = 0.01 m (Taking minimal distance)

Gravitational Constant = G = 6.67 x 10⁻¹¹ N.m²/kg²

So,

**F = Gm₁m₂/r²**

**F = (6.67 x 10⁻¹¹ N.m²/kg²)(0.01 kg)(80 kg)/(0.01 m)²**

**F = 5.34 x 10⁻⁷ N**

This Force is very small in magnitude due to the light masses of both objects.

**Therefore, the pencil is not pulled towards a person due to a very small magnitude of force between them, due to lighter masses.**

What do zooplankton and krill have in common?

**Krill and plankton are two groups of organisms found in the ocean. Krill are species of crustacean related to shrimp, and serve as a very important link in the food chain of the sea. Plankton consist of a larger group of organisms with much more variety, including bacteria, algae, protozoans, jellyfish and some species of cephalopods.**

**Propulsion**

The primary factor that determines whether a species is plankton or not is propulsion. Plankton organisms lack the ability to swim against the tide, and instead float from place to place on sea currents. They may be capable of some movement, and some types of plankton can even hunt for food, but none is powerful enough to make its own headway through the ocean. Adult krill are capable of swimming against currents, but their larvae and eggs fall into the plankton category.

**Variation**

Krill are crustaceans of the Euphausiacea order, which consists of 86 different species. Plankton, on the other hand, can come from a wide variety of different species and orders. Plankton fall into three broad categories, depending on their primary function. Phytoplankton are plant-like organisms, capable of photosynthesis. Zooplankton are animal plankton species that get their nutrients by eating other microscopic organisms. Bacterioplankton are the smallest plankton, and often serve as food for zooplankton and other lifeforms.

**Appearance**

Krill species have similar characteristics and generally resemble tiny shrimp. Most species reach around 2 centimeters (0.8 inches) as adults, while the largest species can reach sizes of up to 15 centimeters (5.9 inches). Plankton, on the other hand, consists of organisms of many different shapes and sizes. The smallest categories include microscopic viruses, protozoans, small crustaceans, and other tiny organisms. At the larger end of the scale, megaplankton are any plankton over 2 centimeters (0.8 inches) in size, and include large animals, such as cephalopods and jellyfish. The largest plankton is the lion's mane jellyfish, which can reach 2.5 meters (8.2 feet) in diameter and grow tentacles more than 36.5 meters (120 feet) long.

**Role**

Plankton and krill serve similar, but slightly different, roles in the food chain. Phytoplankton synthesize nutrients, while bacterioplankton recycle nutrients from decomposing matter in the ocean, providing some of the fundamental sources of nutrition for all ocean creatures. Zooplankton serve to concentrate those nutrients by eating smaller plankton and serving as food for larger creatures. Krill are one step up in the food chain, eating plankton and serving as a nutrient bridge from microscopic life forms to larger fish and mammals.

Together, Denise and her brother painted a total of 3 5 of a living room wall. Denise painted 3 5 of that part, and her brother painted the rest. What part of the living room wall did Denise paint herself? Denise paintedof the living room wall.

**Answer:**

**9 ÷ 25**

**Explanation:**

The computation of the part of the living room that should be painted is shown below:

**= Living room painted × rest of the part painted **

= 3 ÷ 5 × 3 ÷ 5

= **9 ÷ 25**

We simply multiplied with the above two items and the same is to be considered

A gold puck has a mass of 12 kg and a velocity of 5i – 4j m/s prior to a collision with a stationary blue puck whose mass is 18 kg. After an elastic collision, the blue puck has a velocity of 2i – 2j m/s. What is the velocity of the gold puck after the collision?

A. 2i –j m/s

B. 3i –j m/s

C. 2i – 2j m/s

D. 3i – 2j m/s

Pick the third one C

The** ** **velocity **of the gold puck **after **the **collision **be (2i - j) m/s.

The rate at which a body's displacement changes in relation to time is known as its **velocity**. Velocity is a vector quantity with both magnitude and direction. SI unit of **velocity **is meter/second.

Given parameters:

**Mass **of the gold puck: m = 12 kg

**Velocity **of it before collision: u = 5i – 4j m/s.

**Mass **of the stationary blue puck: M = 18 kg.

**Velocity **of it after collision; V = 2i – 2j m/s.

We have to find: the **velocity **of the gold puck after the collision: v = ?

From conservation of linear **momentum**, we get:

Total momentum of the system **before **collision = Total momentum of the system **after **collision

⇒ mu + M.0 = mv + MV

⇒ v = u - MV/m

⇒ v = (5i – 4j) m/s - (2i – 2j)m/s×18/12.

⇒ v = (5i – 4j) m/s - (3i - 3j) = (2i - j) m/s.

Hence **velocity** of the **gold** **puck **after the collision be (2i - j) m/s.

why are force and velocity different?

**Answer: If you apply force to an object the velocity changes. But it doesn't work the other way around apply velocity and the force (no!) Velocity does not change on an object. A force pushes or pulls on an object, but velocity is simply something an object has I hope this makes sense to you. Hope this helps :) **

Table tennis (or Ping Pong as it is more commonly known in the US) was invented in 1880s Victorian England. It was an adaptation the popular game lawn tennis as a way of continuing to play inside during the winter when it was too cold to play outside.

**Answer:**

A point is won by a player when the opponent cannot hit the ball with a racket over the net and onto the other side of the table. Each game is won by being the first player to win 11 points, and be at least 2 points ahead of their opponent. The equipment needed to play table tennis would be a table, rackets, and balls. Some of the rules are no hand-on table (even leaning your hands on the table is not allowed!) Also, if the ball hits the net, you have to serve again.

4. A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm', what is the mass of the gas in the tube in mg?

**Answer:**

Mass, m of gas is 0.2504 grams.

**Explanation:**

First, we need to solve for the volume of the cylindrical tube.

Volume of cylinder is given by the formula;

[tex] V = 2\Pi r^{2}h[/tex]

Where, V represents volume.

π represents pie

r represents radius.

h represents height or length.

Given the following data;

Radius, r = 1.5cm

Length, h = 14.4cm

Density, d = 0.00123g/cm³

Substituting into the equation;

[tex] V = 2 * 3.142 * (1.5)^{2}14.4[/tex]

[tex] V = 2 * 3.142 * 2.25 * 14.4[/tex]

[tex] V = 203. 6016[/tex]

Therefore, the volume of the cylindrical tube is 203. 6016cm³

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, density is given by the formula;

[tex]Density = \frac{mass}{volume}[/tex]

[tex] Mass = density * volume [/tex]

Substituting into the equation, we have;

[tex] Mass = 0.00123 * 203. 6016 [/tex]

Mass = 0.2504g.

Atomic theory describes the motion of particles in solids, liquids, and gases. Which statement best describes the particles in a given state of matter?

A. The particles in gases have a fixed position but can vibrate.

B. The particles in solids have a fixed position but can vibrate.

C. The particles in solids are very close to each other but they are able to move past each other. D. The particles in gases are very close to each other but they are able to move past each other.

B is the answer because a solid would not be able to hold its shape if it was able to move around

**Answer:**

B. The particles in solids have a fixed position but can vibrate

**Explanation:**

Answer choice "A" is incorrect because particles in gases are not held by bonds and move freely (not fixed).

Answer choice "C" is incorrect because while solids are close in proximity, their particles do not move past each other.

Answer choice "D" is incorrect because while the particles in gases are able to move past each other, they are not arranged in close proximity. In fact, them being spread out and free is why they are able to move past each other.

In a certain semiconducting material the charge carriers each have a charge of 1.6 x 10-19

C. How many are entering the semiconductor per second when the current is 2.0 nA?

**Answer:**

1124923453 electrons

**Explanation:**

The formula for charge in coulomb ,C =Current in amperes, A * Time in seconds, s

Given in question ;

Charge = 1.6 * 10⁻¹⁹ C

Current = 2.0 nA = 2*e⁻⁹ A

Calculate time in seconds as

1.6 * 10⁻¹⁹ = 2*e⁻⁹ * t

1.6 * 10⁻¹⁹ /2*e⁻⁹ = t

6.48e⁻¹⁶ s = t

So using t=6.48e⁻¹⁶ s and current =2*e⁻⁹ A , the charge will be;

C = 2*e⁻⁹ * 6.48e⁻¹⁶ =1.799e⁻¹⁰ C

But 1 coulomb = 6.25 x 10¹⁸ electrons

so 1.799e⁻¹⁰ C = ?,,,,{ 6.25 x 10¹⁸} *{1.799e⁻¹⁰} = 1124923453.06 electrons

Answer:

Kindly check the explanation section.

Explanation:

The statement given in the question or problem above is true or let's say it is correct. And the statement describes different kinds or types of push up.

Push up is a kind of excercise that is being done mainly to strengthen the arm and the cheat. The way one goes about it determines which part of the body one is strengthening.

The kind of push up in which one has to close up the gap between his or hands is known as the close push ups. This kind of push up strengthens the arm more than the other part of the body and the more one puts his or her hands closer the more problematic the push up excercise becomes.

Other types or kinds of push ups are the Slow Eccentric Push Ups, Wide Push Ups, Staggered Push Ups, T push ups, Fingertip Push Ups and many more.
