Answer:
Vr = 3.24m/s
The boat is going 3.24m/s relative to the bank of the river.
Explanation:
The relative speed of the boat to the bank Vr is the resultant of speed of boat relative to the water Vb and the speed of boat as a result of the water current or wind Vw
Vr = √(Vb^2 + Vw^2) .....1
Given;
Vb = 2.6m/s
Vw = distance downstream/time = 690m/355s
Vw = 1.94m/s
From equation 1 above; substituting the values
Vr = √(2.6^2 + 1.94^2)
Vr = 3.24m/s
The boat is going 3.24m/s relative to the bank of the river.
Answer:
His weight on Earth is 1097.6N
Explanation:
You have to apply Newton's Second Law, F = m×a where F is force, m is mass and a is accerleration. Then, you have to substitute the following values into the equation :

Let m = 112kg,
Let a = 9.8m/s²,


I believe you are correct! Have a good day! <3
Based on the information in the graph, the atom which is listed below is the most stable would be A. Oxygen-16 (O-16).
The appropriate value in blank given is Δf = 5.5 x
Hertz.
We have vibrational - rotational spectrum Hydrochloric Acid.
We have to investigate the estimated separation between absorption peaks and fill the blank.
<h3>What is vibrational - rotational spectrum ?</h3>
Rotational–vibrational spectroscopy is a branch of molecular spectroscopy. It deals with the infrared and Raman spectra of molecules in the gaseous phase.
According to the question -
The estimated separation between absorption peaks in the vibrational-rotational spectrum of HCl is denoted by Δf and is equal to -
Δf = 5.5 x
Hertz
Hence, the appropriate value in blank given is Δf = 5.5 x
Hertz.
