Explanation:

1 mole of nitrogen atoms moving at 35.0 m/s possesses approximately 27.8 joules of energy.

To calculate the energy possessed by 1 mole of nitrogen atoms moving at 35.0 m/s, we need to consider both the kinetic energy and the molecular mass of nitrogen.

The kinetic energy (KE) of an object is given by the equation KE = 1/2 * m * v^2, where m is the mass and v is the velocity.

The molar mass of nitrogen (N₂) is approximately 28.0134 g/mol, which can be converted to kilograms by dividing by Avogadro's number (6.022 × 10^23). This gives us a mass of approximately 4.65 × 10^(-26) kg for one nitrogen atom.

Plugging in the values, we have KE = 1/2 * (4.65 × 10^(-26) kg) * (35.0 m/s)^2.

Evaluating the equation, we find that the kinetic energy possessed by one nitrogen atom is approximately 4.62 × 10^(-23) joules.

Since we are considering 1 mole of nitrogen atoms, we need to multiply this value by Avogadro's number to get the energy possessed by 1 mole. Avogadro's number is 6.022 × 10^23, so the total energy is approximately 2.78 × 10^1 joules, or 27.8 J.

Answer:

A wrecking ball has the capability to destroy a building due to the greater mass and kinetic energy than the yo-yo.

When the spring is stretched by 1.0 cm, it stores 0.003 J of energy.

The spring stiffness is quantified by the spring constant, or k. For various springs and materials, it varies. The stiffer the spring is and the harder it is to stretch, the larger the spring constant.

The following equation describes the energy held in an ideal spring that is stretched or compressed by a distance x from its equilibrium position:

E = (1/2) k x^2

where k = spring constant and x = distance stretched or compressed.

The spring constant k =  60 N/m

distance stretched x = 1.0 cm = 0.01 m.

Substituting these values,

E = (1/2) (60 N/m) (0.01 m)^2

E = 0.003 J

Answer:

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast.

Answer:

The blue motorcycle.

Explanation:

The red one, since it has more mass, meaning it is denser, would drag on less. Less mass equals more momentum, since there is less holding it down.

Answer:

option c is correct

Explanation:

we know that

2as=vf^2-vi^2

vf=24 m/s

vi= 0 m/s

a=g= 9.8 m/s^2

s=vf^2-vi^2/2a

s=(24)²-(0)²/2*9.8

s=576/19.6

s=29.4 m

The mass of MnO₂ required by 4 g of NaCl in the chemical reaction is 1.487 g.

The balanced chemical reaction of NaCl, MnO₂ and H₂SO₄ is given as follows;

4NaCl + MnO₂ + 4H₂SO₄ → MnCl₂ +  4NaHSO₄ + Cl₂ + 2H₂O

From the chemical equation given above, we can calculate the mass of 4NaCl  and MnO₂  as follows;

where;

4NaCl = 4 ( 23 + 35.5 ) = 234 g

MnO₂  = ( 55 + 32 ) = 87 g

The mass of MnO₂ required by 4 g of NaCl in the chemical reaction is calculated as;

4NaCl + MnO₂ + 4H₂SO₄ → MnCl₂ +  4NaHSO₄ + Cl₂ + 2H₂O

in this equation, 234 g of NaCl ---------> 87 g of MnO₂

                           4 g of NaCl -------------> ? MnO₂

= ( 4 x 87 ) / ( 234 )

= 1.487 g

If a ray of light travels from air into a liquid, as shown in figure below. The ray is incident upon the liquid at an angle of 30.0°. The angle of refraction is 22°, and the refractive index of the liquid would be 1.334.

It is the phenomenon of bending of light when it travels from one medium to another medium. The bending towards or away from the normal depends upon the medium of travel as well as the refractive index of the material.

By using Snell's law,

Refractive index of the liquid = sin(i) /sin(r)

                                                =sin(30) /sin(22)

                                                = 1.334

The answer is B) I. The electric field will have the greatest magnitude at point I because it is the closest point to the charged conductors. The closer to the conductors, the greater the electric field magnitude.

Electric field is an invisible force field that surrounds any object that has an electric charge. It is measured in terms of volts per meter (V/m) and is responsible for the attraction or repulsion of two objects with different electric charges. The force of the electric field is determined by the amount of charge on the objects and the distance between them. Any changes in the electric field will cause a corresponding change in the force felt by the objects. Electric fields can be created by moving charges, such as those found in electric currents, or by static charges, such as those found on a charged object. Electric fields are essential for the transmission of electrical signals and are used in many applications, from telecommunications to medical imaging.
