V=d/t
V=10/4
V=2.5 m/s (more per second
Combustion is the answer i just took the test
No, people are not. A contract is, but people are not.
Answer:
Explanation:
<u>Conditions for Equilibrium</u>
There are three forces applied to Bethany: T1 to the right making an angle of 30° with the ground, T2 to the left making an angle of 45° with the ground, and the weight W down the y-axis. Since the system is assumed to be at rest, the forces must be in equilibrium.
Please refer to the image below.
In the y-axis:
The projections of the tensions in the vertical direction are
Thus, replacing into the first equation:
Now for the x-axis
The components of T1 and T2 in the horizontal direction are
Replacing
Solving for T1
Replacing in [1]
Computing the trigonometric values and simplifying
Solving
And therefore
