Answer: Potential Energy: PE = m x g x h Mass: m = PE / (g x h) Acceleration of Gravity: g = PE / (m x h) Height: h = PE / (m x g) Where, m = Mass, g = Acceleration of Gravity h = Height Gravitational Acceleration of the earth is 9.8 m/sec2.
Explanation:
Answer:
Pluck velocity = 83.34 m/s
Explanation:
The initial angular speed of the rod before it was hit,
The angular speed of the rod and pluck rotating together,
The period of rotation, T = 0.736 s
Using the principle of conservation of angular momentum:
~ A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin. The Celsius scale is part of the metric system.
Answer:
Force,
Explanation:
Given that,
The water in the plumbing in a house is at a gauge pressure of 250,000 Pa.
We need to find the force caused on the top of the tank inside a water heater if the area of the top is . Let F is the force. We know that the force acting per unit area is called pressure exerted. It is given by :
So, the force caused on the top of the tank inside a water heater is . Hence, this is the required solution.
