What is the definition of balanced forces? i need help i cnt find the definition on dictionary.com

Physics

kicyunya [14]3 years ago

Any group of 2 or more forces is balanced if the sum of all of their strengths and directions adds up to zero. Here's an example that I just made up:. Take 50 ropes. Tie one end of every rope all together into one big fat knot, and then have a tug of war in 50 different directions. Get 10 football players and 40 cheerleaders to each take the end of one rope, then everybody spread out and start pulling. It's possible that if everybody stood in just the right place, they might all cancel each other out, and the big knot in the center might just hang there and not move at all ... just as if there was NO FORCE on it at all. If that happened, we would know that the group of 50 forces acting on the knot is "balanced".

brainly a child on a swing set swings back and forth with a period of 3.3 s and an amplitude of 25°. what is the maximum speed o
beks73 [17]

Maximum speed of the child as she swings is  2.23 m/s.

<h3>Step by Step Calculation:</h3>

T=3.3 s is the oscillation's time period.

The swing's greatest angle is 25° (max).

The swing's bottom will have the following kinetic energy:

k=12mv2...........(1)

The mass in this situation is m, and the speed is v.

The potential energy change is expressed as,

∆U=mgL1-cosθmax...............(2)

Here, L is a string's length and g is the acceleration caused by gravity. L is given as,

L=gT24π2

Combine equation (1) with (2)

12mv2=mgL1-cos, maxv=2g, maxv=gT24, maxv=g2T22, maxv=9.8 m/s

22.33 m/s, 22.31 s22.31 cos25°

Therefore, the child's top speed is 2.23 m/s.

<h3>What is Oscillation ?</h3>
  • The process of any quantity or measure fluctuating repeatedly about its equilibrium value in time is known as oscillation.
  • A periodic change in a substance's value between two values or around its central value is another way to define oscillation.

Given the fact that energy conversion is not entirely efficient, it is impossible to produce a perpetual motion machine.

<h3>What is a perpetual motion machine?</h3>

The perpetual motion machine in one that is able to work continuously without stopping. This would mean that the efficiency of this machine must that the machine is 100% efficient which violates the second law of thermodynamics.

Thus, given the fact that energy conversion is not entirely efficient and energy looses cause machines not function effectively, it is impossible to produce a perpetual motion machine.
