Answer:

19.5 m

Explanation:

EN LANZAMIENTO DE PROYECTILES, LA VELOCIDAD HORIZONTAL

PERMANECE CONSTANTE.

PRIMERO ENCUENTRA LA VELOCIDAD VERTICAL

v^{2}y = 2(9.80 m/s^{2})(1.8 m) = \sqrt{35.3 m^{2}/s^{2}} = 5.94 m/s

LUEGO ENCUENTRAS EL TIEMPO QUE LA FLECHA PERMANECE EN EL

AIRE.

t =  5.94 m/s /9.80 m/s^{2} = 0.61 s

FINALMENTE ENCUENTRAS LA DISTANCIA HORIZONTAL TOTAL.

x = 32 m/s(0.61 s) = 19.5 m

ale4655 [162]

Answer:

1. The nucleus is about 1/2 the size of the atom

Explanation:

Alpha particles are positive charge particles and they are bounced back by the nucleus because nucleus is also same size

Now in present experiment Rutherford found that very few alpha particles are bounced back along same path which shows that very small region inside the nucleus is having positive charge and rest part of the atom is empty.

Now if we found that half of the alpha particles are bounced back then it shows that size of the nucleus is very large now as compare to previous one because only nucleus can bounce back the alpha particles

so correct answer will be

1. The nucleus is about 1/2 the size of the atom

According to newton's third law of motion, when a hammer strikes and exerts force to push it into a piece of wood, the nail
Darya [45]
According to newton's third law of motion, when a hammer strikes and exerts force to push it into a piece of wood, the nail <span>C. exerts an equal or opposite force on the hammer. The third law of motion states that every action has an equal BUT opposite reaction. This means that the nail exerts the same force the hammer exerts on it.</span>

Longer wavelengths of light, such as _______, have ________ energy than shorter wavelengths, such as _________
Ilya [14]

Answer:

Micro and radio waves.

Lower energy.

Gamma rays.

Explanation:

The electromagnetic spectrum is the range of frequencies of electromagnetic radiation and their respective wavelengths.

Ionising radiation os defined as the energy required of photons of a wave to ionize atoms, causing chemical reactions.

The energy of the wave depends on both the amplitude and the frequency. If the energy of each wavelength is a discrete packet of energy, a high-frequency wave will deliver more of these packets per unit time than a low-frequency wave. In summary, the longer the wavelength, the lower the energy to ionise.

The velocity of a wave is directly proportional to the frequency of that wave.

c = f * lambda

Where,

c = velocity of the wave

f = frequency of the wave = 1/time

Lambda = wavelength.

From the above expression, the longer the wavelength, lambda the shorter the frequency.

Examples of waves with longer wavelengths are, micro and radio waves, while radiations with shorter wavelengths like gamma rays.

Why do we have 365 days in a year?
uranmaximum [27]
We have 365 days in a year because that is the approximate time of the world revolving around the sun once. It takes 365.25 days to go around once, but the calendar is 365, so we add leap years to add a couple more days.
