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=

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

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
I believe the answer is 3/8. The whole portion of employees, which is translated as 8/8 is deducted by 5/8, which is the population of male employees.
Answer:
5/7
Step-by-step explanation:
Divide 1.28 by 2 answer .64 notepads divide by 3. u get .29 each so add .29 twice. u get .58 add 1.59 twice. u get 3.18. pens 1.98. add .64 + .58 + 3.18 + 1.98= 6.38 so answer is A
Answer: 2
Step-by-step explanation: In order to find out the radius you first need to find out the diameter. Diameter times pie or 3.14 equals the area. So, if the area is 12.4 you need to divide 12.4 by 3.14 which gives you 3.94 which rounds up to 4. The radius is half of the diameter so divide 4 by 2 to get 2
