Atoms may be bonded together by losing, gaining, or sharing _____________. Question 1 options: A, photons
B. energy
C. electrons
D. neutrons
E. protons

Answers

Answer: Option (C) is the correct answer.

Explanation:

An atom consists of three subatomic particles which are protons, neutrons and electrons.

The protons and neutrons are present inside the nucleus. Whereas electrons revolve around the nucleus.

Whenever there is a bond formed by loss, gain or sharing between any two atoms then it is due to the electrons.

Hence, we can conclude that atoms may be bonded together by losing, gaining, or sharing electrons.
D. neutrons , is fit....

Temperature and silica content determine the of magma.

Answers

I think the correct answer is that they can determine the viscosity of the magma. The viscosity of a magma is largely controlled by the temperature, composition and the gas content. Also, silica content can define a magma type. It is said that higher silica content magma has a higher viscosity than those with lower silica content.

The forces acting on a falling leaf are

Answers

Answer:

Gravitational and resistance force.

Explanation:

The push or pull on any object which causes an object to move is called force. The forces can be of many types. The forces acting on the falling leaf are :

  • Gravitational force : The force that acts in downward direction is called the force of gravity. This force pulls every object towards it.
  • Resistance force/ normal : The force that act opposite to gravitational force is called the resistance force. It opposes the direction of motion of the leaf.
the forces acting on a leaf are gravity and air resistance.In some cases the only force acting on an object is gravity, if that occurs then its called freefall.
