check eqs #7 & 8 from link below, which summarizes rotational dynamics in last column.Gulheider said:A torque of 70 N-m acts for 10s on a disk with moment of inertia 160kg*m^2. If the disk is originally stationary, what's final angular speed of the disk?
The "I please 1 ph problem" is a common phrase used to describe a situation where someone is struggling to understand or solve a problem related to pH levels. pH is a measure of the acidity or basicity of a solution, and problems with pH can arise in various scientific fields such as chemistry, biology, and environmental science.
pH is measured on a scale of 0 to 14, with 0 being the most acidic, 14 being the most basic, and 7 being neutral. pH is typically measured using a pH meter or pH strips, which change color based on the acidity or basicity of the solution being tested.
There are several factors that can affect pH levels, including the concentration of hydrogen ions or hydroxide ions, temperature, and the presence of acids or bases in the solution. Environmental factors such as pollution and human activity can also impact pH levels in natural bodies of water.
Solving a pH problem involves identifying the cause of the issue, such as too much acid or base in the solution, and then taking steps to neutralize the pH. This can be done by adding a base to a solution that is too acidic, or adding an acid to a solution that is too basic. It is important to carefully measure and adjust the pH to ensure it reaches the desired level.
pH is an important concept in science because it can affect the behavior of substances and reactions. For example, pH levels can impact the solubility of a substance, the growth of plants, and the survival of aquatic organisms. In addition, understanding pH is crucial for maintaining a healthy environment and for various industrial processes such as water treatment and food production.
