A pulley is another sort of basic machine in the lever family. We may have utilized a pulley to lift things, for example, a banner on a flagpole.
<u>Explanation:</u>
The point in a fixed pulley resembles the support of a lever. The remainder of the pulley behaves like the fixed arm of a first-class lever, since it rotates around a point. The distance from the fulcrum is the equivalent on the two sides of a fixed pulley. A fixed pulley has a mechanical advantage of one. Hence, a fixed pulley doesn't increase the force.
It essentially alters the direction of the force. A moveable pulley or a mix of pulleys can deliver a mechanical advantage of more than one. Moveable pulleys are appended to the item being moved. Fixed and moveable pulleys can be consolidated into a solitary unit to create a greater mechanical advantage.
Answer:
110 mL
Explanation:
Ideal gas law:
PV = nRT
Assuming the container isn't rigid, and the pressure is constant, then:
V/T = V/T
Plug in values (remember to use absolute temperature).
V / 293 K = 150 mL / 393 K
V = 110 ml
Hope u understood!

Answer:
Proton
Explanation:
Proton is a subatomic particle and determines the identity of an element. each element is identified by its atomic number. In an element, the number of protons in the nuclei of the atoms of the element is same as the atomic number of that element and this number is different for each element. for example, Boron has 5 protons in its nuclei, hence the atomic number of the element is 5.
An object held in place by gravity
The end point would be (4,-1).
<u>Explanation:</u>
When you multiply a vector with a scalar, it is known as a scalar multiplication. This multiplication is as simple as multiplying each component of the vector by the scalar because scalar is just another way to call a real number. The result of this multiplication is always a vector.
Multiplying a positive scalar larger than one will increase the magnitude of the vector, but not it's direction. A positive scalar smaller than one will decrease the magnitude. And negative scalar will reverse the direction and increase or decrease the magnitude depending on whether scalar is more than one or less than one.
