Answer:
frequency = 19.56 Hz
Explanation:
given data
length L = 7 m
mass m = 7 g
mass M = 2.50 kg
distance d = 4 m
to find out
fundamental frequency
solution
we know here frequency formula is
frequency = ...........1
so here d is given = 4
and v = ..........2
tension T = Mg = 2.50 × 9.8 = 24.5 N
and μ = = = kg/m
so from equation 2
v =
v = 156.52
and from equation 1
frequency =
frequency =
frequency = 19.56 Hz
1. Friction (Example: when you rub your hands together and you start to feel heat.)
2. Attract each other. (Example: Every object has a gravitational pull of some sort. The larger the object, the stronger the gravitational pull. This is why the sun is able to keep all eight planets in orbit around it.)
3. Hope this helped :)
There’s no diagram

The energy used is B) 43,200 J
Explanation:
The power used by the blender is related to the energy in input by the equation
where
P is the power
is the energy in input to the blender
t is the time interval
Since we know that
P = 300 W
t = 180 s
We can find that
However, we are said that the blender has an efficiency of 80%: this means that only 80% of the input energy is actually used to make the smoothie. Therefore, the energy used is

Answer:
6 amps
Explanation:by Kirchhoff's loop rule the current at any point in the loop must be equal or charge would be building up. The current at the ammeter is equally to the total current through the sun of the paths in parallel which it is in series with
