Answer:

1) Has a rocky, metallic composition -Both

2) Experiences retrograde rotation, spinning clockwise as viewed from above- Venus

3)Experiences the greenhouse effect, which warms the planet - Both

4) Is the densest planet in the solar system - Earth

5) Is located an ideal distance from the Sun, allowing it to support life -Earth

6) Is one of the brightest objects in the night sky, sometimes mistaken for a star-Venus

Explanation:

Venus and Earth are terrestrial planets. They have rocky surface. Venus is characterized by a very thick atmosphere which traps the sun light and makes it the hottest planet of the solar system. Greenhouse effect warms both the planets.

Earth is the only planet on which life exists. It is located at ideal distance from the Sun which helps to maintain sustainable conditions -temperature to support life on it. Venus is known as morning and evening star as it is the brightest objects.

Earth is the densest planet of the solar system having density 5.51 g/cm³. Venus experiences retrograde rotation due to the tilt of its axis (177.3°). Due to this tilt it appears to rotate in opposite direction than other planets.

1). both

2). Venus

3). Venus catastrophically; Earth too but much less.

4). Earth

5). Earth

6). Venus (It would be pretty hard for US to mistake Earth for a star.)

The mass of block B is twice the mass of block A, while the mass of the pulley is equal to the mass of block A. The blocks are l

marshall27 [118]

Answer:

C)the right cord pulls on the pulley with greater force than the left cord

Explanation:

As we can see the figure that B is connected to the right string while A is connected to the left string

Now force equation for B as it will move downwards is given as

$(2m)g - T_B = (2m)a$

similarly for block A which will move upwards we can write the equation as

$T_A - mg = ma$

now we know that pulley is also rotating so the tangential acceleration of the rope at the contact point with pulley must be same as that of acceleration of the blocks

so here pulley will rotate clockwise direction

So tension in the right string must be more than the left string

So correct answer will be

C)the right cord pulls on the pulley with greater force than the left cord

A balloon will stick to a wooden wall if the balloon is charged

grigory [225]

<h2>Answer: either way</h2>

The balloon contains neutral charge atoms, that is, it has the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge).

Then, when two objects come into contact, the electrons of one of them can become part of the other.

Thus, by bringing the balloon closer to the wall, the wall, which is also made up of atoms, will reorder its charges in such a way that its electrons or protons become part of the balloon, charging it.

Indicate whether the statement is true or false. Any force that causes an object to move in a circular path is called a centripe

Anna35 [415]

True, the definition of "centripetal force" is <span>a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.</span>

What is the purpose of an experiment design?

Eddi Din [679]

An experimental design is used to assign variables for testing. In contrast to a control design where nothing is changed, the experimental design allows you to test various new inputs to see how they would vary from the original results.

What is a loose icy body with a long narrow orbit?

Bumek [7]

A comet is the loose, icy body with a long, narrow orbit.
Comets are very small solar system body made mainly of ices mixed with smaller amounts of dust and rock. Most comets are not larger than a few kilometers across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices. Their speeds vary depending on their orbits and where they are in it. The closer they are to the sun, the faster they are going.
