We know that the centripetal acceleration is zero, since the summation of forces is the mass times the acceleration in the x- component.
<span>If a behavior tends to increase after a consequence occurs, that consequence is most likely used as a catalyst. In terms of chemical reactions, catalysts are used to increase the rate of reaction. Given that, when an object causes a situation to become more frequent, then it is considered as a catalyst.</span>
Answer:
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Explanation:
Diameter = 135 m
Radius, r = 0.5 x 135 = 67.5 m
It revolves at a constant rate and takes 30 minutes
Period, T = 30 minutes= 1800 s
Linear velocity, v = radius x angular velocity
v = 67.5 x 3.98 x 10⁻³ = 0.2355 m/s
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Answer:
Solution
Explanation:
A solution is a mixture composed of solute which are dissolved in a solvent which may or may not contain water.
They are homogeneous mixtures in which the solute particles are evenly distributed uniformly in the solvent.
- The solute is usually the substance dissolved.
- It is usually present in a smaller amount compared to the solvent.
- The dispersing medium is the solvent.
- It allows for the solute to go into solution.
- A solution in which the solvent is water is called an aqueous solution.
- Their particles do not settle on standing.
- They are usually clear and may have color.
Answer:
-There are no other charges nearby.
Explanation:
-There are no other charges nearby.
If there is no net charge in nearby space then the force on this charge will be ZERO
-If there are other charges nearby, they must all have the same sign as Q.
There there is nearby charge of same sign then it will have repulsion force on Q
-If there are other charges nearby, they must all have the opposite sign of Q.
if there is nearby charge of opposite sign then the force must be attraction force.
-If there are other charges nearby, the total positive charge must equal the total negative charge.
If there exist two type of charges nearby then there may exist either attraction or repulsion force on it
