Which best describes the difference between radiation and conduction? Conduction cannot happen when both objects are solids. Conduction requires two objects to be in physical contact.
Conduction can occur between two objects that are very far apart.
Conduction decreases the movement of the atoms in both objects.

Answers

Answer 1
Answer: Conduction is went two objects are directly touching each other. They must come into contact with each other. Like sitting on a cold bench that eventually becomes warm due to your body heat. Think of radiation as the suns rays when you get sunburnt.
Your Answer would be B. Conduction requires two objects to be in physical contact.
Hope this helps!

An object's weight is dependent upon its location in the universe. Why is this true?A. This is true because gravitational force is the magnitude of weight acting on an object's mass and since weight varies in different places in the universe, both gravitational force and mass also vary.B.This is true because weight is the amount of matter in an object. Because gravity is a force, and force is proportional to weight, both gravity and weight vary in different places in the universe.C.

HELP ASAP REAL ANSWERS PLEASE You push a box across the floor with a force of 30 N. You push it 15 meters in 8 seconds. How much work did you do? How much power did you use?

Answers

When you lift a box up off the floor, you must exert a force at least equal to the weight of the box. If you lift the box at constant speed, you "do work" on the box that would be equal to the force you exert (the weight of the box) times the height through which you lifted the box. If you exert a force of 50 Newtons on the box and lift it 1 meter high, then you did (50 N)x(1 m) or 50 N-m of work on the object. 1 Newton-meter is called a Joule (J), pronounced "jewel." In lifting the 50 N box upward 1 meter at constant speed, you would do 50 Joules of work on the box. That means your body used 50 J of energy to lift the box.

and here is the Equation for Work: Work = Force x distance, or W = F d.

Anions are formed by _____.

Answers

Answer:

Gaining electrons

Explanation:

Anions are negatively charged ions.

When an atom gains some electrons then anions are formed.

As electrons are negatively charged so anions are also negatively charged ions.

Anions are attracted by the cathode which is positively charged electrode.

An anion is formed by the gain of one or more electrons to the atom.

PLEAAAASSEEEEE HELPP! A volcano forms near a tectonic plate boundary. What can you infer about the formation of this volcano?

Answers

Answer:

The volcanoes are directly associated with the convergent type of plate boundary.

In a convergent boundary, two plates move towards each other. Due to their collision, a subduction zone is formed where the denser plate goes down below the other less dense plate, and the trench lies above this zone, which is a long, narrow depression and marks the boundary between the two distinct plates.

As the denser plate subducts, it melts and mixes up with the magma. This magma then rises upward due to the force exerted by the convection current. This magma then reaches the surface towards the over-riding plate, resulting in the formation of volcanoes, or volcanic or island arcs.

Thus, the convergence of two plates leads to the formation of a volcano.

You can infer that the volcano was formed from a convergent boundary (two tectonic plates that collide, and for a volcano specifically one plate probably went under the other pushing up magma underground).
