The maximum speed the mass can have before it breaks is 2.27 m/s.
The given parameters:
- <em>maximum mass the string can support before breaking, m = 17.9 kg</em>
- <em>radius of the circle, r = 0.525 m</em>
The maximum speed the mass can have before it breaks is calculated as follows;
Thus, the maximum speed the mass can have before it breaks is 2.27 m/s.

Answer:
It would be A, because it is has more height in which the potential energy would be greater.
Answer:
The pack has fallen 275.6 m
Explanation:
The pack is in free fall, so it is moving by uniform accelerated motion, so we can use the following suvat equation:
where, choosing upward as positive direction:
v is the final velocity
u is the initial velocity
is the acceleration of gravity
s is the vertical displacement
For the pack in this problem,
u = 0
v = -73.5 m/s
Solving for s, we find how far the packet has fallen:
And the negative sign means the direction of the displacement is downward.
Answer:
True
Explanation:
If there's no preference over the string case (upper case or lower case), one can convert both strings to upper case or to lowercase and then compare the converted strings to test if they're equal or not.
An Illustration is
string a = "Boy"
string b = 'bOy"
if(a.ToUpper() == b.ToUpper() || a.ToLower() == b.ToLower())
{
Print "Equal Strings"
}
else
{
Print "Strings are not equal";
}
The above will first convert both strings and then compare.
Since they are the same (after conversion), the statement "Equal Strings" will be printed, without the quotes
