Answer:
224.6 N
Explanation:
We can use first the formula to calculate the centripetal acceleration, given by:
where the Vt is the tangential velocity, and R is the radius of the circular motion.
Then, for our case we have:
And now we multiply this acceleration by Miguel's mass (11 kg) to obtain the centripetal force acting on him:
Answer:
one dimension of motion on a circle is "back and forth"
Explanation:
Whether the position graphs look the same or not is a function of the acceleration (and velocity), and how position is measured.
For a circle centered at the origin, uniform motion around the circle will be equivalent to sinusoidal motion in the x- or y-directions. So, that motion is equivalent to sinusoidal motion "back and forth", however it may be generated.
The "back and forth" motions of a piston in a cylinder (connected to a crankshaft), and of a pendulum, are almost sinusoidal, but not quite. Their position graphs will differ slightly from the graph of position of an object moving around a circle.
__
On the other hand, if the circular motion is plotted as the length of the radius versus time, it will be a constant -- not "back and forth" at all.
__
In short, plots of similar motion will look similar.
Answer:
1 A, 3 B, and 7 A are examples of <em>group number</em> on the periodic table.
Explanation:
The table that consists of elements arranged systematically on the basis of atomic numbers is called periodic table. Groups and periods are two important part of a periodic table. A periodic table contains seven horizontal rows, called as periods and 18 vertical columns, called group.
The groups name is given in the form of number and alphabets. It represents the columns present in the periodic table.
Hence, 1 A, 3 B, and 7 A are examples of <u><em>group number</em></u> on the periodic table.
