<h3><u>Answer;</u></h3>

The force needed to keep it in a circular motion will<u><em> increase </em></u>

<h3><u>Explanation;</u></h3>
  • <em><u>Centripetal force is the force that keeps an object or a body in a circular path while in circular motion.</u></em>
  • Centripetal force depends on <em><u>the speed of the object and the radius of the circular path, together with the mass of the object in circular motion.</u></em>
  • <em><u>Centripetal force increases with increase in mass of the object in circular motion and the velocity of the object.</u></em> Centripetal force increases with decrease in the radius of the circular path.
  • <u><em>Centripetal force is given by mv²/r;</em></u> where, m is the mass, r is the radius of the circular path and v is the velocity of the circular path; thus in this case it will be;

<em><u>  = (0.5 × 2²)/1 </u></em>

<em><u>   = 2 Newtons </u></em>

By definition we have that the acceleration will be given by
 a = V ^ 2 / R
 Where
 V = speed
 R = Radio
 Substituting
 a = (2 ^ 2) / (1) = 4m / s ^ 2
 then, the force needed to keep it in a circular path will be
 f = m * a = (0.5) * (4) = 2N

a place that is typically cold because of an increase in altitude would most likely have what type of climate? dry climate mild
Marta_Voda [28]
A place that is cold because of an increase in altitude has a mountain area climate or simply, mountain climate. An area that is high in altitude typically has a colder temperature because of the increased amount of rainfall they have. Also, air tends to cool as it rises in temperature.

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.
