The answer is number 2 stomata.
<h2>The distance between students is 2.46 m</h2>
Explanation:
The force of attraction due to Newton's gravitation law is
F =
Here G is the gravitational constant
m₁ is the mass of one student
m₂ is the mass of second student .
and r is the distance between them
Thus r =
If we substitute the values in the above equation
r =
= 2.46 m
Answer:
The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.
Explanation:
The chew toy is at equilibrium and experimenting three forces from three distinct dogs. The Free Body Diagram depicting the system is attached below. By Newton's Laws we construct the following equations of equilibrium: (<em>Sp</em> is for Spot, <em>F</em> is for Fido and <em>St</em> is for Steinberg) All forces and angles are measured in newtons and sexagesimal degrees, respectively:
(1)
(2)
If we know that , and , then the components of the force done by Steinberg on the chewing toy is:
The magnitud of the force is determined by Pythagorean Theorem:
Since the direction of this force is in the 3rd Quadrant on Cartesian plane, we determine the direction of the force with respect to the eastern semiaxis:
The magnitude and direction of the force applied by Steinberg are approximately 15.192 newtons and 126.704º.
Answer:
After 3 hours.
Explanation:
This is a encounter problem.
We start by writing the position equation of both objects.
We assume that acceleration is equal to zero in both boats ⇒ They move with constant speed
We put the origin of coordinates in the harbour so after 6 hours the first boat travels
The first boat will be 42 mi far from the harbour.
The position equation for a motion with acceleration equal to zero is :
Where is initial position
v is the speed
t is time and is initial time
Then is time variation
For the first boat :
Because we set
For the second one :
In the encounter : x1(t) = x2(t) ⇒
So after 3 hours they have the same position relative to the harbour
We can check by replacing the value t = 3h in both position equations
For x1(t) :
For x2(t) :
With enough energy it can but i don’t think we are advanced enough so the answer is no
