It's basically asking for the acceleration. When an object is in free fall, the acceleration is just gravity. so in this case ∆v = 2.45 because it is the gravity on that planet.
Answer:
9.17 m/s
Explanation:
Impulse = change in momentum
FΔt = mΔv
(166 N) (0.39 s) = (7.06 kg) Δv
Δv = 9.17 m/s
The pH of the solution is 0.37.
<h3>What is the pH of the solution?</h3>
We can write the equation of the reaction as;
Number of moles of 
= 24/1000 * 1 = 0.024 moles
Number of moles of 
= 60/1000 * 1 = 0.060 moles
Given that the reaction is 1:1, the limiting reactant is NaOH
Number of moles of NH4Cl left over = 0.060 - 0.024 = 0.036 moles
Concentration of left over NH4Cl = 0.036 moles/(24 + 60)/1000
= 0.43 moles
pH = -log(0.43)
pH = 0.37

The product of (wavelength) x (frequency) is always the same number ... the wave's speed.
So if the wavelength is somehow reduced to 1/4 its original length, the <em>frequency is immediately multiplied by 4</em> . That's the only way their product can remain the same.
In one of the greatest coincidences to arise on Brainly in quite some time, Choice-C is the correct choice for BOTH #15 and #16 .
Choice-C is the only situation in which the source is a different distance from each ear.
