Answer:
The volume will not contract to one fourth of the original.
Explanation:
Applying Charles's Law as:
Given ,
V₁ = ?
V₂ = 2 L
T₁ = 5 °C
T₂ = 20 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (5 + 273.15) K = 278.15 K
T₂ = (20 + 273.15) K = 293.15 K
Using Charles law as:
Thus, the volume will not contract to one fourth of the original. (1/4 of 2 L is 0.5 L).
<span>Sharon
is jumping from an 18-foot diving board with an initial upward velocity
of 4 ft/s. When Susan jumps, Megan throws a beach ball up to Susan with
an initial upward velocity of 16 ft/s from a height 5 feet off the
ground. To the nearest hundredth of a second, it will take C. 1.08 seconds for the ball to reach Sharon after she jumps. </span>

The minimum frequency is
while the maximum frequency is
Using the relationship between frequency f of a wave, wavelength
and the speed of the wave v, we can find what wavelength these frequencies correspond to:
So, the wavelengths of the radio waves of the problem are within the range 188-545 m.
