A = 59.35cm
B = 196.56g
C = 74.65g
<u>Explanation:</u>
We know,

and L = x+y
1.
Total length, L = 100cm
Weight of Beam, W = 71.8g
Center of mass, x = 49.2cm
Added weight, F = 240g
Position weight placed from fulcrum, y = ?

Therefore, position weight placed from fulcrum is 59.35cm
2.
Total length, L = 100cm
Center of mass, x = 47.8 cm
Added weight, F = 180g
Position weight placed from fulcrum, y = 12.4cm
Weight of Beam, W = ?

Therefore, weight of the beam is 196.56g
3.
Total length, L = 100cm
Center of mass, x = 50.8 cm
Position weight placed from fulcrum, y = 9.8cm
Weight of Beam, W = 72.3g
Added weight, F = ?

Therefore, Added weight F is 74.65g
A = 59.35cm
B = 196.56g
C = 74.65g
The variable is the disinfectant that is used, because there different ones being used
The stereo uses an energy of

in a time

, therefore the power of the stereo is given by

We also know that the power of an electrical device is related to its voltage, V, and its resistance, R, by the following equation

therefore, we can rearrange the equation to calculate the resistance of the stereo:
Answer:
True.
Explanation:
When an object's atoms gain or lose electrons, it becomes an ion, becoming charged.
Hello!

Begin by finding the acceleration of the puck. Use the kinematic equation:

The initial velocity is 0 m/s since the object was at rest, so we can rewrite the equation as:

Plug in the given distance and time:

Find the net force using the formula F = m · a (Newton's Second Law)
F = 0.18 · 0.1
F = 0.018 N
