the wind pushes a paper cup along the sand at a beach. the cup has a mass of 0.025 kg and accelerates at a rate of 5 m/s2. how much force is the wind exerting on the cup

Answers

To find the force,

 ⇒ must know the force's formula ⇒ F = MA

M: mass of the objectA: acceleration of the object

Let's consider the information given:

cup has a mass of 0.025kg --> 'M'accelerates at a rate of 5 m/s^2 --> 'A'

Let's solve:

  [tex]F=MA=0.025kg*5m/s^2=0.125N[/tex]

Thus the force is 0.125N

Answer: 0.125N

Answers

The energy in the bonds in glucose will be broken down and transferred to ATP molecules.

CELLULAR RESPIRATION:

Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules in their cells.

The equation for cellular respiration is as follows:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Based on the illustration using the above equation, the energy stored in the bonds of glucose molecule is broken down and used to synthesize ATP molecules.

a side reaction occurs when acid is added to the system. which species reacts with the acid?

Answers

The reaction is a base

A side reaction occurs when acid is added to the system, so the species reacts with the acid is base.

What are acids?

Acids are those species which have a pH range in between 0 to 7, generally acids are present with hydrogen atom in their molecular formula.

If in any reaction after adding the acid, side reaction wiull occur then in this condition base will reacts with the acid as it has the opposite behavior as of acid and formation of salt & water molecules takes plavce.

Hence the needed species is base.

two step mole conversions, giving brainliest

Answers

Answer:

Our process will be to change the mass of NO2 to moles by dividing by the molar mass, and then we multiply the number of moles with Avogadro's number (6.02 x 10^23)

Molar mass of NO2 = (14) + (16)x2 = 46g/mol

45.8/46 = 0.99 or just 1 mole when you round it.

Now just multiply the moles with Avogadro's number

1 x (6.02 x 10^23)

= 6.02 x 10^23 molecules of NO2 reside in 45.8g of NO2

What are forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

How proud they must be, nevertheless, when they are styled Assistant Attendants, or summoned to the Palace for occasional duty, or ordered to serve as Imperial envoys during the Kamo Festival! Even those who stay at home lose nothing by having served at Court. In fact they make very good wives. For example, if they are married to a provincial governor and their daughter is chosen to take part in the Gosechi dances, they do not have to disgrace themselves by acting like provincials and asking other people about procedure. They themselves are well versed in the formalities, which is just as it should be. What conclusion can be drawn about the authors point of view in this passage? Women who serve in the court are not graceful. Serving in the palace benefits women later in life. Serving in the palace should be the goal for all women. Women who get married later in life receive the most respect. Which of these does the ElectoralCollege NOT elect?A. Vice PresidentB. Chief JusticeC. President LAST ATTEMPT IM MARKING AS BRAINLIEST!!
