Answer:
The centripetal acceleration of the edge of the top
Explanation:
Given:
Speed with which the top rotates = 0.63 m/s
Radius of the top = 0.10 m
To Find:
Centripetal acceleration of the edge of the top =?
Solution:
The centripetal acceleration is the rate at which the tangential velocity changes. Also its direction is always inwards along the radius vector of the circular motion.
We know that centripetal acceleration is
Where
v = velocity
r = radius
Substituting the values
Answer: 3.2
Explanation:
pH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Thus as pH and are inversely related, a solution having lower pH will have more amount of
concentration. And a solution having more pH will have less amount of
concentration.
Thus the solution with lowest pH of 3.2 will have highest hydronium ion concentration.
Answer:
The second vector points due West with a magnitude of 600N
Explanation:
The original vector points with a magnitude of 200N due east, the Resultant vector
points due west (that's how east/west direction can be interpreted, from east to west) with a magnitude of 400N. If we choose East as the positive direction and West as the negative one, we can write the following vectorial equation:
With the negative sign signifying that the vector points west.
