After rubbing a balloon on your shirt, your hair sticks up when the balloon is near your head. Explain how tiny particles on you

and the balloon can make your hair stand up. (1 point) Protons are transferred from your body to the balloon. This gives you a negative charge and the balloon a positive charge. The opposite charges attract. Electrons are transferred from your body to the balloon. This gives you and the balloon a negative charge. The like charges attract. Electrons are transferred from your body to the balloon. This gives you a positive charge and the balloon a negative charge. The opposite charges attract. Electrons are transferred from your body to the balloon. This gives you a negative charge and the balloon a positive charge. The opposite charges attract.​

Almost right. protons are positive and electrons are negative. so when you run the balloon on your hair, electrons are transferred between them (i’m not sure which direction) and now one is positively charged as it lost negative particles and one is negative as it gained negative particles (electrons). opposite charges attract

What is the acceleration of an object that goes from 45m/s to 10 m/s in 5 seconds?
kipiarov [429]

Answer:

\boxed {\boxed {\sf a= -7 \ m/s^2}}

Explanation:

Acceleration is the change in velocity over time.

a= \frac {v_f-v_i}{t}

The object accelerates <em>from</em> 45 meters per second <em>to </em>10 meters per second in 5 seconds. Therefore,

v_f=10 \ m/s \\v_i= 45 \ m/s \\t= 5 \ s

Substitute the values into the formula.

a= \frac{ 10 \ m/s - 45 \ m/s}{5 \ s}

Solve the numerator.

a= \frac { -35 \ m/s}{5 \ s}

Divide.

a= -7 \ m/s/s

a= -7 \ m/s^2

The acceleration of the object is -7 meters per square second. The acceleration is negative because the object's velocity decreases and the object slows down.

What is the relationship between balancing equations and the law of conservation of matter
harkovskaia [24]
Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

A sealed beaker of what you are told is aqueous nickel sulfide was given to you by the local chemist and you put it on the windo
Masteriza [31]

Answer: D. It is a SUSPENSION

Explanation:

SUSPENSION

This is a combination of two or more single substances. The properties of the components involved are not however changed or lost as is the case with compounds.

For this reason this mixture can be separated due to sedimentation or filtering.

After a few days, this occurs in the aqueous nickel sulfide because the solid nickel sulfide is separating from the water.
