Answer
b. the number of atoms in each molecule.
Explanation:
Given that,
Mass of a tribble, m = 2.5 kg
Radius, r = 1.4 m
The force on the tribble from the bucket does not exceed 10 times its weight.
To find,
The maximum tangential speed.
Solution,
The force acting on the tribble is equal to the centripetal force.
F = 10mg
The formula for the centripetal force is given by :
![F=\dfrac{mv^2}{r}](https://tex.z-dn.net/?f=F%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
v is maximum tangential speed
![v=\sqrt{\dfrac{Fr}{m}} \\\\v=\sqrt{\dfrac{mgr}{m}} \\\\v=\sqrt{{10gr}} \\\\v=\sqrt{10\times 9.8\times 1.4} \\\\v=11.7\ m/s](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cdfrac%7BFr%7D%7Bm%7D%7D%20%5C%5C%5C%5Cv%3D%5Csqrt%7B%5Cdfrac%7Bmgr%7D%7Bm%7D%7D%20%5C%5C%5C%5Cv%3D%5Csqrt%7B%7B10gr%7D%7D%20%5C%5C%5C%5Cv%3D%5Csqrt%7B10%5Ctimes%209.8%5Ctimes%201.4%7D%20%5C%5C%5C%5Cv%3D11.7%5C%20m%2Fs)
So, the maximum tangential speed is 11.7 m/s.
Answer:
Stupid
Explanation:
Because there is never a answer when we are trying to find one
<h3>Answer</h3>
a. 8J
b. 90J
<h3>Notes formula</h3>
W = F × s
W = Work done (J)
F = Force (N)
s = distance (m)
<h3>Known that </h3>
a. F = 4N
s = 2m
b. F = 30N
s = 3m
<h3>Question</h3>
a. W = ..?
b. W = ..?
<h3>Way to do it</h3>
a. W = F × s
= 4N × 2m = 8J
b. W = F × s
= 30N × 3m = 90J
