Explanation:

Answer:

gases; solids.

Explanation:

gases take up the most volume, meaning the particles are more spread apart (disorder, entropy, etc. if you are familiar with those). solids have the particles closer together, opposite of gases.

Particles are spaced the farthest apart in gases and are the closest in solids.

Gases consist of very large numbers of tiny spherical particles that are far apart from one another compared to their size. Gas particles are in constant rapid motion in random directions.

The particles in solids are arranged in a regular way. The particles in solids move only by vibrating about a fixed position. This gives solids a fixed shape and means that they cannot flow like liquids. The hotter a solid gets, the faster its particles vibrate.

"A particle is a small piece of anything. Particle can also refer to a subatomic particle with mass and structure, but takes up hardly any space at all. Particles are tiny."

Answer:

1. The phone call goes out, transmits through radio waves, then moves to the central hub. Then the signals go to the nearest tower to the receiver of the call.

2. long wavelength

3. radio waves

Explanation:

1. A cell phone call is works basically as a two-way radio, consisting of a radio transmitter and a radio receiver. When you dial a call to a friend on your cell phone, your phone converts your voice into an electrical signal, which is then transmitted through radio waves. The radio waves then moves to the central hub. Then the signals go to the nearest tower. The network of cell towers then relays the radio wave to your friend’s cell phone, which converts it to an electrical signal and then back to sound again.

2. AM means amplitude modulation. In AM frequencies, sound signals are modulated by changing the amplitude or maximum height of radio waves. AM frequencies use longer wavelength radio waves than FM frequencies. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere, and thus travel over longer distances than FM waves.

3. Cell phones use radio waves to communicate.

Answer:

0.1m

Explanation:

k = 64N/m

Ep = 0.32J

x = ?

Ep = 1/2 * kx²

make x the subject of the formula

x² = 2Ep/k

x = √(2Ep/k)

x = √(0.64/64)

x = √0.01

x = 0.1m

Answer:

Gamma radiation.

Explanation:

Electromagnetic waves are waves produced with respect to the interaction of electric field and magnetic field. They can be arranged with respect to their increasing or decreasing wavelength to form a pattern called electromagnetic spectrum.

Gamma radiation can be used for sterilization purpose due to the fact that it has a relatively high amount of energy, and do not produce any characteristic radiation.

Answer:

c, 280,000J

Explanation:

You should use the equation KE (Kinetic Energy) = [tex]\frac{1}{2} mv^2[/tex]

m = 2500

v = 15

KE = [tex]\frac{1}{2} * 2500 * (15)^2\\[/tex]

KE = 281250 Joules.

This is consistent with the answer B, as all of the parameters given to you are rounded to 2 significant figures so naturally, the answer should also be rounded to 2 sig figs.

KE = 280,000 J

Answer:

to produce energy for use by the body.

Explanation:

Catabolism can be defined as a metabolic process which typically involves the breaking down of complex molecules (inorganic and organic) into smaller and simpler molecules. This metabolic process (catabolism) is always accompanied with the release of energy in the form of adenosine triphosphate (ADP).

Some examples of the complex molecules broken down through catabolism are proteins, nucleic acid, polysaccharides, and lipids; which are broken into the following smaller molecules, amino acids, nucleotides, monosaccharides, and fatty acids respectively.

Hence, the main purpose of catabolism in living organisms such as humans, animals and plants is to produce energy for use by the body.

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Explanation:

For this exercise we will use Newton's second law, let's set a reference system where the x axis is parallel to the plane, in the adjoint we can see the forces in the system.

           sin  35 = Wₓ / W

            cos 35 = W_y / W

            Wₓ = W sin 35

            W_y = W cos 35

            Wₓ = 2500 9.8 sin 35

             Wₓ = 14052.6 N

let's write the equations for each axis

and

Y axis  

       N-W_y = 0

       N = W_y

X axis  

       F -Wₓ = m a

       F = Wₓ + m a = mg sin 35 + m a

       F = m (a + g sin 35)

let's calculate

       F = 2500 (5 + 9.8 sin 35)

       F = 26552.6 N

The force that pulls the car down is Wₓ = 14052.6 N and the one that pushes the car up is F = 26552.6 N

Answer:

Coal, crude oil, and natural gas are all considered fossil fuels all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago.

Explanation:

Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. A fossil fuel is a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.

formula: m1 * d1 = m2 * d2

datos:

m1= 45 kg

d1= 160 cm

m2= 38 kg

d2= x

reemplazamos datos en formula:

45kg * 160cm = 38kg * d2

El 38 pasa al otro lado de la igualdad a dividir:

(45kg * 160cm) / 38 kg = d2

Resolvemos: (kg se cancela con kg, quedando solo los cm)

7200cm / 38 = d2

Resultado:

d2 = 189.5 cm

Answer:

15.625m

Explanation:

Using the equation of motion

v² = u²+2as

u and v are the initial and final velocities

a is the acceleration

s is the distance

Get the acceleration

According to Newton's second law;

F  = ma

8 = 10a

a = 8/10

a = 0.8m/s²

We are also given

v = 5m/s

u = 0m/s

Substitute into the formula above

v² = u²+2as

5² = 0²+2(0.8)s

25 = 1.6s

s = 25/1.6

s = 15.625m

Hence the dog will cover a distance of 15.625m before coming to rest

Answer:

a)  E = 1.06 10⁻¹⁹ J,     b)   v = 9.78 10⁵ m / s

Explanation:

The physical magnitudes can be given in several units, but in general all must be reduced to the same system in a given exercise, the most used system is the international (SI)

           1 eV =q V=  1.6 10⁻¹⁹ J

let's reduce the quantities requested

a) E = 1.0 eV to Joule

           E = 1.0 eV (1.6 10⁻¹⁹ J / 1 eV)

           E = 1.06 10⁻¹⁹ J

b) the kinetic energy is given by

           K = ½ m v²

           v = [tex]\sqrt{\frac{2K}{m} }[/tex]

the mass of the proton is

          m = 1,673 10⁻²⁷ kg

let's reduce the energy to the SI system

           E = 5000 ev (1.6 10-19 J / 1 eV) = 8000 10⁻¹⁹ J

let's calculate

           v = [tex]\sqrt{ \frac{2 \ 8000 \ 10^{-19}}{1.673 \ 10^{-27} } }[/tex]

           v = [tex]\sqrt{ 95.637 \ 10^{10} }[/tex]

           v = 9.78 10⁵ m / s

Answer:

A mousetrap makes use of a simple machine called a lever.

Explanation:

In a second-class lever the effort force is at the other end, with the load in the middle. In a third-class lever, the load is at the end and the effort force is between the fulcrum and the load. When you set the mousetrap, you are using a second-class lever. Sorry if I get this wrong. I am in 5th grade! ♥

Answer:

it is 9m/s , hope it helps

Ans: It attracts iron armature

Answer:

Explanation:

In a sonometer , expression for speed of wave produced can be given as follows .

v = [tex]\sqrt{\frac{T}{m} }[/tex]

v is velocity , T is tension in wire , m is density per unit length .

Here v is inversely proportional to square root of m . So if m becomes m / 4

velocity changes as follows .

velocity = [tex]\sqrt{\frac{T}{\frac{m}{4} } }[/tex]

= [tex]\sqrt{\frac{4T}{m} }[/tex]

= 2v

velocity becomes two times . Hence to make velocity two times , mass per unit length  has to be changed to one fourth value , keeping tension constant .

Answer:

W = 7056  J

Explanation:

Given that,

Mass of a load, m = 60 kg

Distance moved, d = 12 m

We need to find the amount of work. The work done by an object is given by :

W = Fd

So,

W = mg×d

W = 60 kg × 9.8 m/s²×12 m

W = 7056  J

So, the amount of work done is 7056  J.
