Answer:
The answer is A. Fluid and white blood cells move into the tissue from nearby blood vessels.
Explanation:
Mechanical advantage = (output force) / (input force)
Mechanical advantage = (60 N) / (12 N)
Mechanical advantage = 5.0
Answer:
maximum work is done in the case
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
Explanation:
As we know that the Work done is product of force and displacement
So we have
A) Steve put in 50 J of work moving a box 50 meters.
So here we have
50 = F . 50
F = 1 N
B) Doing 400 J of work, Penny pushed her cat 80 meters.
So here we have
400 = F . 80
F = 5 N
C) Samantha did 365 J of work dragging a wagon across 73 meters of lawn.
So here we have
365 = F . 73
F = 5 N
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
So here we have
144 = F . 16
F = 9 N
So maximum work is done in the case
D) Clark pushed a crate from the chair, 16 meters across the room, doing 144 J of work.
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
