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, 
................ii
form i and ii we can write
⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
The reading on the scale is greater than your actual weight.
Answer:

Explanation:
water
Answer:
230.4kg
Explanation:
volume of the room = l× b×h
volume= 8×6×4
volume=192m3
density= mass/volume
hence mass= density × volume
mass= 1.2kgm-3 × 192m3
mass= 230.4kg
The hint in this problem is in the word "about" or
approximately how many pounds.
So we could find the solution by estimation through rounding
off.
We know that almonds cost about 3.50 per pound and
a bag costs about $7.00.
Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2
pounds.
The answer is 2 pounds.
