Answer:
Step-by-step explanation:
- The sum of exterior angles of a polygon is equal to 360 degrees
Add the total males together: 13 + 85 = 98,
So the total male need to be 98,
the total adults is given as 200.
The total women would be 200 - 98 = 102
The table with those three totals is table D.
240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to
after 240 days.
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mv

=
r

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
