I think the correct answer from the choices presented above is the first option. The characteristics of low energy waves are <span>long wavelengths and low frequencies. Energy is established to be indirectly proportional to wavelengths and frequencies.</span>

The correct answer to the question is : A) Long wavelengths and low frequencies.

EXPLANATION:

From Planck's quantum theory we know that the energy of any electromagnetic wave having certain frequency is  E = h\nu.

Here, \nu is the frequency of the wave.

Hence, more is the frequency of the wave, the wave is more energetic.

We know that wavelength and frequency are inversely proportional to each other.

Hence, a low energy wave means a wave having long wavelength or low frequency.

Mount Everest rises to a height of 8,850 m above sea level. At a base camp on the mountain the atmospheric pressure is measured
Mamont248 [21]

Answer:

74.86°C

Explanation:

P₂ = Vapour pressure of water at sea level = 760 mmHg

P₁ = Pressure at base camp = 296 mmHg

T₂ = Temperature of water = 373 K

ΔH°vap for H2O = 40.7 kJ/mol = 40700 J/mol

R = Gas constant = 8.314 J/mol K

From Claussius Clapeyron equation

ln\frac{P_2}{P_1}=\frac{\Delta H}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)\\\Rightarrow ln\frac{760}{296}=\frac{40700}{8.314}\left(\frac{1}{T_1}-\frac{1}{373}\right)\\\Rightarrow ln\frac{760}{296}\times \frac{8.314}{40700}+\frac{1}{373}=\frac{1}{T_1}\\\Rightarrow 0.0028735=\frac{1}{T_1}\\\Rightarrow T_1=347.996\ K

T₁ = 347.996 K = 74.86°C

∴Water will boil at 74.86°C

Which of the following statements are true? The internal resistance of a battery decreases with decreasing temperature. A batter
Eddi Din [679]

Answer:

Option B

Explanation:

  • The obstruction offered by the battery is known as its internal resistance. Electricity is produced by the chemical reactions inside the battery. The pace of the responses is straightforwardly relative to the temperature and the power delivered by the battery increments. In this way, the inward opposition of the battery increments as diminishing the temperature.  
  • The battery is a gadget which generates electrical energy by the chemical reactions that takes place inside it.  
  • In this way, the announcement a battery is a gadget that produces electricity by the transformation of chemical energy into electrical energy is valid.  
  • The potential difference between the terminals of a battery, when no current is streaming into an outer circuit is called emf of the battery and if the potential distinction is measure when the current is streaming into the outside circuit is called terminal voltage .
  • The battery attempts to move the negative charge from the low potential terminal to the high potential terminal of the battery. The potential vitality of the negative charges is high at the lower potential terminal and the potential vitality of the negative charge is low at the high potential terminal. Along these lines, the battery attempts to move the charges from high potential terminal to low potential terminal.
