The angular speed of the minute hand is the ratio between the angle covered and the time taken. The angle covered by the minute hand is
, while the time needed is
, so the angular speed is
And the tangential speed is given by
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that displacement is given as
now the displacement in 4.5 s and t = 4 s is given as
now displacement is given as
Part b)
So displacement of the ball in given interval of t = 4.00 to 4.5 s
time interval is given as
average velocity is given as
Part c)
So displacement of the ball in given interval of t = 4.00 to 4.1 s
average velocity is given as
Similarly for time interval t = 4.0 s to t = 4.01 s
average velocity is given as
Similarly for time interval t = 4.0 s to t = 4.001 s
average velocity is given as
so instantaneous velocity is given as
Answer:
150
Explanation:
The correct answer is 150. Let's go through it together.
<u>Formula for Volume</u>
l = length
w = width
h = height
V = (l)(w)(h)
Now that we're reminded of the formula for volume, let's solve.

Displacement is the distance between the starting and ending points, in the direction from the starting point to the ending point, all regardless of the route followed from the starting point to the end point.
The woman's displacement is therefore 30 meters north.
As an element is a pure substance which contains only one kind of atoms ,so nitrogen -N2,contains only one kind of atom which is nitrogen of two atoms. And compound is also a pure substance which contains two or more kind of atoms. ... So,nitrogen is an element not an compound.
