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
2
=

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

The correct answer is, A) Nubia.
<em>The kingdom once merged with Egypt was Nubia.
</em>
<em>I</em>n ancient Egypt, lower Nubia was part of Egypt. It was located between the first and the second cataract of Aswan. In that time the region was known as Wawat.
