La velocidad de crucero de un avión comercial es de 900 km / h. La velocidad más alta jamás alcanzada en una carrera de Fórmula 1 es 303,5 m / s. ¿Cuál de los dos es mayor?

Answer:

Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction.

Explanation:

Answer:

The wavelength decreases as the electron speeds up. The wavelength increases as the electron slows down.

Answer:

A. 130J / kg°C

Explanation:

Amount of heat (Q) = 5200 J

mass (m) = 2 kg

temperature (dt) = 20°C

specific heat capacity (S) = ?

We know

Q = msdt

5200 = 2 * s * 20

s = 5200 / 40

s = 130 J /kg °C

Answer:

Water set free by magma began to cool down the Earth's atmosphere, until it could stay on the surface as a liquid. ... The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor.

Explanation:

Según el modelo cinético, las moléculas de gas están en constante movimiento.

La energía cinética promedio de las moléculas del gas depende de la temperatura del gas y de la masa molar del gas.

Si los dos gases ocupan el mismo volumen a la misma temperatura, la energía cinética promedio ahora depende de la masa molar de los gases individuales. Cuanto menor sea la masa molar del gas, mayor será la velocidad media de las moléculas del gas.

El oxígeno gaseoso tiene una masa molar menor que el dióxido de carbono. Por lo tanto, el oxígeno tiene una velocidad molecular promedio mayor que el dióxido de carbono.

Answer:

the answer is c

Explanation:

Answer: Stored energy

Answer:

E_total = 3 N / A

Explanation:

The electric field is a vector magnitude so when adding we must use vectors, in this case as the initial field E = 4N / c goes towards the axis axis and the field created by the fixed charge (E1) is also on the axis x we can add in scalar form.

               E_total = E + E₁

the expression for the field of a point charge is

                E₁ = k q₁ / r²

for the point x = 2m, they do not say that the total field is zero, so the charge q1 must be negative

                 E_total = E -k q₁ / r₂

we substitute

                   0 = E - k q₁ / r²

                   q₁ = [tex]\frac{E r^2}{k}[/tex]

let's calculate

                   q₁ = [tex]\frac{4 \ 2^2}{9 \ 10^{-9}}[/tex]

                   q₁ = 1.78 10⁻⁹ C

now we can calculate the field for position x = 4 m

                   E_total = 4 - 9 10⁹  1.78 10⁻⁹ / 4²2

                   E_total = 3 N / A

The answer is B. It has a central nucleus composed of 29 protons and 35 neutrons, surrounded by an electron cloud containing 29 electrons.

Given the data from the question, the correct statement is:

An atom is composed of a centrally placed nucleus (containing protons and neutrons) and a cloud of electrons revolving round it.

Mass number = Proton + Neutron

64 = 29 + Neutron

Collect like terms

Neutron = 64 – 29

Neutron = 35

Note

Proton = Electron = 29 (since the atom is neutral)

Thus, we can conclude that the atom has central nucleus composed of 29 protons and 35 neutrons, surrounded by an electron cloud containing 29 electrons  (Option B)

Answer:

See answer below

Explanation:

In order to do this, we just need to apply the expression to determine the time of flight. This is given by:

t = 2 V₀ Sinθ / g   (1)

We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:

t = 2 * 200 Sin60° / 9.8

Now that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:

X = V * t   (2)

We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:

X = 200 cos60° * 35.348

X = 100 * 35.348

Answer:

1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.

Explanation:

Answer:

F1 = 16 N and F2 = 24 N

Explanation:

Formula used => F = m×a and v-u= at

So, as we know force = mass × acc.

so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now

Here u= 0 as the objects are placed at rest initially..

thus, v= at

FOR 1ST BLOCK

16= <math> F1/5 </math> × 5 ==> F1 = 16 N

FOR 2ND BLOCK

15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

Answer:

0

Explanation:

Defining velocity :

Velocity is a vector which is the ratio of a person's total displacement with time.

Displacement, in simple terms refers to the distance between an individual's initial position to his final position.

Man's initial position = House

After all his navigation and points covered irrespective of the distance ;

Final position = House

Hence, we can conclude that the man's Displacement is ;

Final position - Initial position = 0

Hence,

Velocity = Displacement / time taken

Velocity = 0 / 3

Velocity = 0
