Answer:

The distance between two objects

Explanation:

Depending on how far away or how close two objects are will affect the gravity.

Gravitational force strength depends only on two factors, mass of objects and distance between the objects.

Explanation:

The distance between two objects experiencing the gravitational force are in inverse relationship in proportionality.

That is, when distance between two increases, “strength of gravitational force decreases”, and vice versa. If the one of the mass is doubled, force of gravity also doubles and if it increases, force of gravity also increases.

Answer:

4.14 m/s

Explanation:

Dr. Dodgeball is a playful game in which one player, as the virus, hits others with a sensory ball or tags them with their elbow. Those hit must 'self-isolate' or get 'vaccinated' by designated doctors to stay in the game.

Explanation:

How to Play Dr. Dodgeball

Dr. Dodgeball is an imaginative game inspired by current events and offers an interactive understanding of various concepts such as self-isolation and cooperation. To play the game, one player assumes the role of the virus, tasked with hitting their peers with a sensory ball on a trampoline.

If a player is struck by the ball, they must 'self-isolate' on the edge of the trampoline. This 'isolation' involves counting to 10 and can happen up to three times. On the fourth hit, the player performs a dramatic cough and pretends to 'die'.

In another variation, the virus player tags people with their elbow. Once tagged, a player has 10 seconds to receive a 'vaccine' from one of the two players acting as doctors by being untagged with an elbow touch. If a doctor manages to tag the original virus player, the game ends, and either the roles rotate or the same doctor becomes the new virus for the next round.

The game is flexible and can be played in various settings including neighborhoods, parks, and even remotely using mobile devices.

Overall, Dr. Dodgeball can be described as a playful way to engage in physical activity while incorporating themes from the health world, such as virus transmission and preventive measures, into the gameplay.

Answer:

-5 m/s²

Explanation:

Acceleration = change in velocity / change in time

a = (v − v₀) / (t − t₀)

a = (-0.4 m/s − 0.6 m/s) / 0.2 s

a = -5 m/s²

The ball decelerates at a rate of -5 m/s².

Explanation:

The transcontinental railroad was worked on from both sides of America. At the Pacific Ocean and the Atlantic Ocean. The purpose was to make travel easier from one side of the country to the other, and to get American items to the east and west of America for export to other countries, as well as a few other reasons such as building up the interior of America.

The transcontinental railroad revolutionized travel by connecting the Atlantic and Pacific coasts, transforming trade and transportation in the United States.

The transcontinental railroad impacted travel by allowing passengers to travel from the Atlantic Ocean to the Pacific. This monumental achievement connected the West Coast with the eastern rail networks, transforming cross-country travel and trade. It spurred the growth of hub cities like Chicago, which became vital for managing the extensive railroad networks.

The correct answers would be option A, C and E.

Explanation:

A material made up of synthetic or semi synthetic compounds is called Plastic. This material is malleable and can be molded into solid form. There are many disadvantages of using the plastics. Three of the main disadvantages are :

- Plastic pollutes the land and water. Because it does not decay.

- Plastic takes an incredibly long time to break down.

- Plastic is not easy to recycle.

Above mentioned problems make the use of plastic so undesirable.

Answer:

A. It pollutes the land and water.

C. It takes an incredibly long time to break down.

E. It isn’t easy to recycle.

Explanation:

Centripetal force is:

F = m v² / r

where m is mass, v is velocity, and r is radius.

Force is proportional to mass, so if mass increases, then force also increases.

If mass increases centripetal force will also increase

A centripetal force is a net force that acts on an object to keep it moving along a circular path.

centripetal force = m[tex]v^{2}[/tex] /r

where m = mass of the object

v = velocity of the object

r = radius of the circular path

since . mass is directly proportional to centripetal force

hence , if mass increases centripetal force will also increase

Answer:

False

Explanation:

An object in uniform circular motion must be changing its velocity in order to move in a circular path.

In fact, remind that velocity is a vector which consists of a magnitude (the speed) and a direction.

When an object is moving in uniform circular motion, the direction of the motion is constantly changing (since the trajectory is a circle): so, this means that the velocity is also changing. However, this does not imply that the speed of the object is changing. In fact, in a uniform circular motion, the speed of the object remains constant.

Answer:

79.1°

Explanation:

Given:

x₀ = 0 m

y₀ = 0 m

x = 19500 cos 32°

y = 19500 sin 32°

v₀x = 1810 cos 20°

v₀y = 1810 sin 20°

t = 9.20

Find:

ax, ay, θ

First, in the x direction:

x = x₀ + v₀ t + ½ at²

19500 cos 32° = 0 + (1810 cos 20°) (9.20) + ½ ax (9.20)²

16537 = 15648 + 42.32 ax

ax ≈ 21.01

And in the y direction:

y = y₀ + v₀ t + ½ at²

19500 sin 32° = 0 + (1810 sin 20°) (9.20) + ½ ay (9.20)²

10333 = 5695 + 42.32 ay

ay ≈ 109.6

The direction of the acceleration is therefore:

θ = atan(ay / ax)

θ = atan(109.6 / 21.01)

θ ≈ 79.1°

Answer:

79.1°

Explanation:

A missile is moving 1810 m/s at a 20.0 degree angle. It needs to hit a target 19,500 m away in a 32 degree direction in 9.20 seconds. The direction of the acceleration that the engine must produce is 79.1°

Answer:

The first law of thermodynamics describes how the heat added to a system is conserved. Heat

⇒ increases the internal energy of the system or is transformed into

⇒ work, or both. Heat is just transformed, not created or destroyed.

Explanation:

edge 2020

The first law of thermodynamics states that the change in internal energy of a system is equal to the net heat transfer into the system minus the net work done by the system. This law emphasizes that energy can be transferred into or out of a system through heat or work, but it cannot be created or destroyed.

The first law of thermodynamics is a fundamental principle that applies to energy conservation in thermodynamic systems. It states that the change in internal energy of a system is equal to the net heat transfer into the system minus the net work done by the system.

In equation form, the first law of thermodynamics is represented as AU = Q - W, where AU is the change in internal energy, Q is the net heat transfer, and W is the net work done by the system.

This law emphasizes that energy can be transferred into or out of a system through heat or work, but it cannot be created or destroyed.

Answer: Option (C) is the correct answer.

Explanation:

In a chemical reaction, where two different compounds or a mate and a compound are reacting with each other then more reactive metal is able to displace less reactive metal.

When only one element gets displaced then it is known as a replacement or single replacement reaction.

For example, [tex]Fe_{2}O_{3}(s) + 2Al(s) \rightarrow Al_{2}O_{3}(s) + 2Fe(l)[/tex]

Here, aluminium is more reactive in nature as compared to iron. Hence, iron is replaced by aluminium and this reaction is known as replacement reaction.

Thus, we can conclude that the given chemical reaction is replacement.

Answer:

2.00 N

Explanation:

Weight is mass times gravity:

W = mg

Mass is density times volume:

m = ρV

Volume of a cylinder is:

V = πr²h

Finding the volume:

V = π (2.00 cm)² (6.00 cm)

V = 75.4 cm³

The density of aluminum is 2.7 g/cm³.  Finding the mass:

m = (2.7 g/cm³) (75.4 cm³)

m = 204 g

Finding the weight:

W = (0.204 kg) (9.8 m/s²)

W = 2.00 N

The aluminum cylinder weighs 2.00 N.

Explanation:

Using trigonometry:

cos θ = Fx / F

cos 30 = 100 / F

F = 115.47

tan θ = Fy / Fx

tan 30 = Fy / 100

Fy = 57.74

The magnitude is 115.47 N and the vertical component is 57.74 N.  Round as needed.
