The force is in the same direction as the load moves. The force is up and the load moves up. This is the same results without the pulley. A fixed pulley makes work easier because you can pull down instead of pushing something up.
The greater the mass of an object, the more inertia it has, so the object resists changes to its motion better.
I do not know the answer sorry :(
A block of aluminum has a volume of 15.0 ml and a mass of 50.5 g. the density is: 3.36 g/ml
To solve this problem the density formula and the procedure that we have to use is:
d = m/v
Where:
- v= volume
- d= density
- m= mass
Information about the problem:
Applying the density formula we get:
d = m/v
d = 50.5 g/15.0 ml
d= 3.36 g/ml
<h3>What is density?</h3>
It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.
What is volume?
It is the space occupied by a body, it is calculated by multiplying its dimensions, for example: length, height and width.

A simple arrangement by means of which EMF are compared is known as a voltmeter.
Discussion about Voltmeter :
- A voltmeter is a straightforward device used to compare electromagnetic fields.
- When there is no current flowing through a cell, its terminal voltage equals its electromotive force (emf). The difference in potential between a cell's electrodes is what determines its terminal voltage. Since voltmeters use the cell's current to draw voltage, they are unable to measure a cell's emf.
- Using a voltmeter, one may determine the voltage generated in an electric circuit. Volts are the emf's SI unit (V). Volts are the voltage's SI unit (V). Non-coulomb force, also known as non-electric force operation, defines emf.
