Investigate and explain that when a force is applied to an object but it does not move, it is because another opposing force is

being applied by something in the environment so that the forces are balanced.
The diagram below shows a box lying on a wedge. Two opposite forces are acting on the box. (1 point)

Force 1 acting downward and Force 2 acting upward on a square box lying on a wedge.

If the box is stationary, which of the following is true about force 1 and force 2?
1. Force 1 Force 2 Comparison of Forces
Gravity Friction Force 1 is stronger than Force 2
2. Force 1 Force 2 Comparison of Forces
Friction Gravity Force 2 is stronger than Force 1
3. Force 1 Force 2 Comparison of Forces
Gravity Friction Force 1 is equal to Force 2
4. Force 1 Force 2 Comparison of Forces
Friction Gravity Force 1 is equal to Force 2

A sample of basalt has smaller crystals than a sample of granite. What is the most likely reason for this?
posledela
The most likely reason is that basalt is an extrusive rock, while granite is an intrusive rock. What this means is that basalt forms at the surface of the earth, where temperatures are cooler. Because of the cooler external temperature, basalt cools relatively quickly, and there isn't as much time for mineral crystals within the rock to align to form larger crystals while the rock is cooling. Granite, on the other hand, forms below the surface of the earth, where temperatures are significantly higher. Therefore, it doesn't cool as quickly, and the minerals within granite have more time to form larger crystals and the rock cools.

The cell potential of the following electrochemical cell depends on the pH of the solution in the anode half-cell:Pt(s)|H2(g, 1a
meriva

Answer:

0.51

Explanation:

Given the Nernst equation;

E= E° - 0.0592/n logQ

E= 355 mV or 0.355 V

E° = 0.34 - 0= 0.34 V

n= 2(two electrons were transferred in the process)

Equation of the reaction;

H2(g) + Cu^2+(aq) -----> 2H^+(aq) + Cu(s)

Substituting values;

0.355 = 0.34 - 0.0592/2 log([H^+]/1)

0.355 - 0.34 = - 0.0296 log [H^+]

0.015/-0.0296 = log [H^+]

Antilog (-0.5068) = [H^+]

[H^+] = 0.311 M

pH = -log[H^+]

pH= - log(0.311 M)

pH = 0.51

Kruka [31]

Answer:

In a semiconductor, the bonding molecular orbitals that contain electrons are referred to as the valence band, while the antibonding orbitals that are completely empty are referred to as the conduction band.

The conduction band occupies a higher energy level than the valence band. The band gap is what separates the two orbitals.
