For this case, the relationship between the two forces is given by:
F1 = nF2
Where,
- F1: output strength
- F2: input force
- n: mechanical advantage
Then, replacing the values we have:
F1 = (2.2)(202)
Having the calculations we have:
F1 = 444.4N
Answer: The output force that only lifts the load is F1 = 444.4N.
Heavier objects do not fall faster than lighter objects when they are dropped from a certain height IF there is no resistance from the air. So, if you were in a vacuum, the two things would fall at the same rate.
The amount of matter in an object is called its, mass. How much the mass weights would be referred to as weight
Answer: 1. False, an ammeter must be placed in a series connection to experience the same current which it is measuring
2. True, a voltmeter measures voltage (electric potential) in volts
3. False, a voltmeter should have high internal resistance such that it does not significantly alters current in a circuit.
4. True, a meters measure current
5. True, voltmeter would measure electric potential across a resistor
6. False, since they tend to influence the current in a circuit, ideally it should have very low resistance near zero
