The wavelength of the radio waves is 3.04 cm.
<h3>Calculation:</h3>
λf = c
λ = c/f
where,
λ = wavelength
c = speed of light
f = frequency
Given,
f = 98.6 MHz = 98.6 × 10⁶
c = 3 × 10⁸
To find,
λ =?
Put the values in the formula,
λ = c/f
λ = 3 × 10⁸/98.6 × 10⁶
= 0.0304 × 10² m
= 3.04 cm
Therefore, the wavelength of the radio waves is 3.04 cm.

the answer is B. surface water can seep downward to become groundwater
Answer:
Zero
Explanation:
Impulse is defined as the change in momentum.
Impulse is also defined as the product of force and the time duration of application of the force.
In the given problem, since there is no motion in the vertical direction, therefore the velocity of the box along the vertical direction is zero. So, momentum of the box along the vertical is also zero.
Hence the change is momentum is also zero along vertical direction.
Thus the impulse delivered by the box is zero.
The answer on Edge would be (A.)= Larger and Cooler ! I'm doing the same thing as y'all. Good luck everyone.
Answer:
107 °F
Explanation:
Given that
The temperature at sea level = 100°F
height ,h= 2000 feet
The average lapse rate = 3.5°F/1000 feet
Given that rise in temperature 3.5°F per 1000 feet.
1000 feet ⇒ 3.5°F
Given that 2000 feet
2000 feet ⇒ 3.5°F x 2 +100°F
2000 feet ⇒ 107 °F
Therefore the temperature will be 107 °F .
