<span>The first three steps in scientific inquiry are related in that they are all equivalent to being on a fact finding mission. The three steps are to find or develop the question that must be answered, to study all related academic literature on the subject, and then to make a guess as to what the answer is.
I hoped I helped!</span>
Answer:
The speed on boat in still water is 
and the rate of the current is 
Explanation:
Since speed , 
Therefore speed of motor boat while traveling upstream is
and speed of motor boat while traveling downstream is
Let speed of boat in still water be 
and rate of current be 
Therefore 
----(A)
and 
------(B)
Adding equation (A) and (B) we get
=>
------(C)
Substituting the value of in equation (A) we get
Thus the speed on boat in still water is and the rate of the current is
Here is the first question
Answer:
F = 10.86 units
Explanation:
The magnitude of a vector in terms of the magnitude of its rectangular components is given by the following formula:
F = √(Fₓ² + Fy²)
where,
F = Magnitude of the Vector = ?
Fₓ = magnitude of the x-component of vector = 8.7 units
Fy = magnitude of y component of vector = - 6.5 units
Therefore, using these values in the equation, we get:
F = √[(8.7 units)² + (- 6.5 units)²]
F = √(117.94 units²)
<u>F = 10.86 units</u>
Answer:
9ms^2
Explanation:
since ,Force=mass*acceleration
then, acceleration=force/mass
and, Force=90N
Mass=10pound
therefore, acceleration=90/10
=9ms^2
