Gabriel desplaza 2,5 m una caja de 40 kg de masa sobre

Physics
1 answer:
soldier1979 [14.2K]3 years ago
7 0

Answer:

El trabajo es  550 n*N

Explanation:

El trabajo se define como un movimiento de una masa al aplicarle una fuerza.

De tal forma que lo podemos escribir como:

W = F*d

Donde se asume que la fuerza se aplica en la misma direccion que el movimiento.

En este caso, sabemos que la caja se mueve una distancia d = 2.5m

Y la fuerza aplicada es 220 N, (la fuerza es paralela a la superficie, entonces se aplica en la misma direccion en la que la caja se mueve)

Entonces el trabajo sera:

W = 2.5m*220N = 550 n*N

The statement "Good locations for turbines are limited" describes a drawback to wind energy.

Answer: Option B

<u>Explanation:</u>

Wind energy is one of the most useful and efficient renewable energy sources. But nothing is ideal in this universe and the same thing applies for wind energy also. The generation of electricity from wind energy requires setting up of turbines.

And these turbines can be set up in plane areas which is free from any disturbance except wind flow. In open area and flat plane surface only the turbines can rotate freely with the effect of wind.

But regions where the wind flow is minimum due to snow formation like the northern region of earth, the turbines cannot be set up there. So the locations for setting up of turbines are limited for good outcome in wind energy. This is one of the drawback of wind energy.

The eyes of some reptiles are sensitive to 850 nm light. If the minimum energy to trigger the receptor at this wavelength is 3.1
mr_godi [17]

Answer:

Minimum number of photons required is 1.35 x 10⁵

Explanation:

Given:

Wavelength of the light, λ = 850 nm = 850 x 10⁻⁹ m

Energy of one photon is given by the relation :

E=\frac{hc}{\lambda}    ....(1)

Here h is Planck's constant and c is speed of light.

Let N be the minimum number of photons needed for triggering receptor.

Minimum energy required for triggering receptor, E₁ = 3.15 x 10⁻¹⁴ J

According to the problem, energy of N number of photons is equal to the energy required for triggering, that is,

E₁ = N x E

Put equation (1) in the above equation.

E_{1}=N\times\frac{hc}{\lambda}

Substitute 3.15 x 10⁻¹⁴ J for E₁, 850 x 10⁻⁹ m for λ, 6.6 x 10⁻³⁴ J s for h and 3 x 10⁸ m/s for c in the above equation.

3.15\times10^{-14} =N\times\frac{6.6\times10^{-34}\times3\times10^{8}}{850\times10^{-9}}

N = 1.35 x 10⁵

The particles that make up protons and neutrons are called
Sphinxa [80]

Answer:

Quark

Explanation:

In the past the proton,neutron and electron were believed to be indivisible. Quarks were later discovered to be particles that make up the proton and neutron. Quarks are known as fast moving points of energy and are usually joined to one another through gluons. Neutron has two down quarks and one up quark while proton has two up quarks and one down quark.
