Answer:
at x=0
=W*L/L
and
=W-
Explanation:
Solve for the tension in the left rope, TL, in the special case that x=0. Be sure the result checks with your intuition. Express your answer in terms of W and the dimensions L and x. Not all of these variables may show up in the solution.
moments is the product of force and the perpendicular distance in line of the action of the given force
from the principle of moments which states that the sum of clockwise moments ,must be equal to the sum of anticlockwise moments.
also, sum of upward forces must be equal to sum of downward forces
Going by the aforementioned,
taking moments about
W*(l-x)=*(L)
=W*(L-x)/(L)..............1
at x=0
=W*L/L
also
+ =W
=W-
Answer:
well when if you are sitting down and then push off of the brick wall you will be backwards so you can't see anything so you might hit someone or something so you would have to be careful
Explanation:
the reason why i think this is because i have a brother who skateboard and he wants to help me get better and when we are just playing we sit down on the skateboard and push off things and ran into a pole because i was backwards and wasn't paying attention so that's why i think that
Converting 209 km/hr to m/s:
209 km/hr = 58.0 m/s
Contact distance = 0.1 m
Using the equation of motion:
2as = v² - u², where initial velocity is 0
a = (58)² / (2 x 0.1)
a = 1.68 x 10⁴ m/s²
Answer: B, Microwaves reach a cell tower, then fiber optic cables send the signal to a cell tower near the person you are calling.
Explanation:
Answer:
If instrument used has louder pitch and due to the fact that pitch depends on frequency we expect that the wave pattern on the graph would it's crest or trough contract more to represent higher frequency
