Answer:
v = 2 m/s
Explanation:
First, we find the angular velocity of the girl by using the following formula:

Now, for the average velocity of the girl we can use the following formula:

where,
r = radius = 200 m
therefore,
<u>v = 2 m/s</u>
Answer:
30.24m
Explanation:
When adding numbers together, we round to the smallest number of decimal places of the numbers, which is 2 decimal places in this case.
24.686m + 2.343m + 3.21m = 30.23<u>9</u> m
≈ 30.24m (round to 2 d.p.)
When you round numbers to a certain digit (hundredth in this case), you would want to look on the digit on its right (thousandth in this case). If that digit is 1-4, you round the digit down. If that digit is 5-9, you round the digit up. Since the digit in the thousandths place is 9, you round the hundredth digit up from 3 to 4.
Answer:Yes
Explanation:yeah i think it could be possible because the universe is so far and wide its probably infinite and if we did i personally believe that we would be absolutely be annihilated by them because we would be so far behind technology wise we would have no use for the\

Answer:
a) The work done by a nonconservative force depends on the path taken. True.
c) A potential energy function can be specified for a conservative force. True
d) A conservative force permits a two-way conversion between kinetic and potential energies. True
Explanation:
Non-conservative forces dissipate. For example, friction or air resistance or drag.
A conservative force's property is that the work done in moving a particle does not depend on the path it has taken. For example, stored energy or potential energy. It permits two-way conversion between kinetic energy and potential energy. For example if a car goes up a hill, it converted kinetic energy in to potential energy. and if the car goes down the hill without hitting the gas pedal, it will roll down converting the potential energy in to kinetic energy.
b) A nonconservative force permits a two-way conversion between kinetic and potential energies. False
e) A potential energy function can be specified for a nonconservative force. False
f) The work done by a conservative force depends on the path taken. False
