The mechanical advantage of the screwdriver that is being described above is equal to 75N. This means that for every 30N that is applied on the screwdriver, this simple machine would in turn apply 75N of force to the lid of the can.
Because it eats plants and animals.
Formula of kinetic energy = 0.5*mass*velocity squared so the answer is 11008j
The downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.
<h3>
Downward acceleration of the cylinder</h3>
The downward acceleration of the solid cylinder is determined from the principle of conservation of angular momentum as shown below;
Iα = Tr
where;
- I is moment of inertia of the solid cylinder
- α is angular acceleration of the cylinder
- T is tension in the string
- r is length of the string
α = Tr/I

where;
- a is the downward acceleration of the solid cylinder
- R is radius of the cylinder
Thus, the downward acceleration of the solid cylinder at the given tension in the string is determined as 2Tr/MR.

Answer:
beat frequency = 13.87 Hz
Explanation:
given data
lengths l = 2.00 m
linear mass density μ = 0.0065 kg/m
String A is under a tension T1 = 120.00 N
String B is under a tension T2 = 130.00 N
n = 10 mode
to find out
beat frequency
solution
we know here that length L is
L = n ×
........1
so λ =
and velocity is express as
V =
.................2
so
frequency for string A = f1 = 
f1 = 
f1 =
and
f2 =
so
beat frequency is = f2 - f1
put here value
beat frequency =
-
beat frequency = 13.87 Hz
