The key idea of the transformation called translation is the gliding or sliding of every point in the plane the same direction. a. True
b. False

Answers

Answer 1
Answer:

Answer:

TRUE

Explanation:

There are different types of transformations, such as rotation, translation or symmetry.

Translation is a type of transformation in which the figure or plane moves all in the same direction.

When a translation is made, the dimensions or measures are not affected. What changes is the position of the figure.
Answer 2
Answer: That statement is true.

There are several definitions about transformation called translation, but the key idea is the gliding or sliding of every point in the plane the same direction.

Hope this helps

The earth-moon relationship is unique in many ways. It is the largest moon in the solar system relative to its host planet. The relative size between the earth and moon are so close, some refer to it as a ________ planet system. binary host lunar

Answers

The earth-moon relationship is unique in many ways. It is the largest moon in the solar system relative to its host planet. The relative size between theearth and moon are so close, some refer to it as a binary planet system. As it is simply a a relationship between a planet and its moon, the system is called a binary system.

The relative size of earth and moon are a little bit of close  in astronomical world.One can find unique relationship between two planetary systems i.e the earth and moon.

In astrophysics the term binary planet system refers to two planets.Here both the planets are of planetary masses.Two planetary bodies will be considered as the binary system if their sizes are proportional to each other and comparable.

Moon is the one satellite in the entire solar system which is larger than other satellites.The weight of the earth is 81 times more than the weight of earth and it is just 384000 km away from earth .Ideally it can not be considered as binary planet system.But it is considered as a binary planet system as their relative size are so close.

Hence the answer of this question is binary planet system.

A net force of 40 N south acts as an object with a mass of 20kg. What is the object's acceleration

Answers

Answer:

a = 2 m/s²

Explanation:

Given: 20 g, 40N

To find: Acceleration (a)      

Solution: To find the acceleration (A), divide the force by the weight    

A = F ÷ m

=  40 ÷  20

= 2 m/s²

Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

The density of ocean water increases when ita. joins the Gulf Stream.
c. gets warmer.
b. gets colder.
d. turns to ice. Please select the best answer from the choices provided A B C D

Answers

The correct answer is (b.) gets colder. The density of the ocean water increases when the water gets colder. Therefore, it is already concluded that the density of the water and its temperature is indirectly proportional since as the density increases, the temperature decreases. 

Answer: Option (b) is the correct answer.

Explanation:

Density means the degree of compactness, that is, when particles of an object or substance are closer to each other then it is said that density of object is high.

Therefore, when ocean water gets colder then particles of water will gain potential energy and thus they will come closer to each other. Hence, there will be increase in density of ocean water when it gets colder.

CondensationRadiationConvectionConduction transfers heat within the atmosphere and ocean.

Answers

Answer:

Explanation:

Sun is the only source of heat on earth. Heat from sun first passes through atmosphere and then fall on the earth's surface i.e. land and ocean.

Condensation, Radiation, Convection, Conduction transfers heat within the atmosphere and ocean such as rise of hot air, cooling and then falling is the example of convection whereas, heat from fire is the example of radiation.
condensation, radiation, convection, conduction are many ways heat is transferred from atmosphere to ocean. however heat comes from the sun then, to the atmosphere.

A water skier has a mass of 79.0 kg and accelerates at 1.40 m/s2. What is the net force acting on him? F = ___ NAnswer choices
56.4
111
77.6
0.018
80.4
774.2

Answers

The answer is 111.

Using Newton's Second Law, F=ma, plugging known values in we get:

F = (79kg)(1.4m/s^2) = 110.6N ≈ 111N

Final answer:

The net force acting on the water skier, calculated using Newton's second law (F=ma), is approximately 111 Newtons.

Explanation:

The net force acting on the water skier can be calculated using Newton's second law, which states that force equals mass times acceleration (F=ma). In this instance, the skier's mass (m) is 79.0 kg and his acceleration (a) is 1.40 m/s2.

By multiplying these values together (F = 79.0 kg * 1.40 m/s2), we find that the net force acting on him is 110.6 Newtons (N). However, this exact value is not listed in the answer choices. Among the given choices, 111 N would be the closest approximation to the calculated value.
