What are the effects of force in our daily life? Force can make a moving object to stop and also make a stationary object to move. The magnitude and the direction of the force on the body are important to change the state of motion. There are many factors that influence the state of motion […]
What is the formula for translation?
What is the formula for translation? In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, use P'(x+a,y+b) . How do you write a translation equation? Key Points A translation […]

How do you achieve long term economic growth?
How do you achieve long term economic growth? 2. Long-term economic growth Increased capital. e.g. investment in new factories or investment in infrastructure, such as roads and telephones. Increase in working population, e.g. through immigration, higher birth rate. Increase in labour productivity, through better education and training or improved technology. What are the consequences of […]
What are the 4 phases of emergency management?
What are the 4 phases of emergency management? These common elements allow you to prepare for and protect yourself and your animals from disaster. Emergency managers think of disasters as recurring events with four phases: Mitigation, Preparedness, Response, and Recovery. The following diagram illustrates the relationship of the four phases of emergency management. What is […]
What percentage is water vapor in the atmosphere?
What percentage is water vapor in the atmosphere? Gaseous water represents a small but environmentally significant constituent of the atmosphere. The percentage water vapor in surface air varies from 0.01% at -42 °C (-44 °F) to 4.24% when the dew point is 30 °C (86 °F). Approximately 99.13% of it is contained in the troposphere. […]
How many groups are on the central atom?
Does boiling point change with temperature?
Does boiling point change with temperature? The boiling point of a liquid depends on temperature, atmospheric pressure, and the vapor pressure of the liquid. When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. Why does the temperature of ethanol not rise when boiled? As a liquid is heated, […]
Which best describes the shape of a convection current?
Which best describes the shape of a convection current? The shape of a convection current would be circular. Convection currents are caused by the very hot material at the deepest part of the mantle rising, then cooling, sinking again and then heating, rising and repeating the cycle over and over. How are convection currents used […]
What is the kinetic energy of a molecule?
What is the kinetic energy of a molecule? Kinetic Energy and Molecular Speed Gas particles are in constant motion, and any object in motion has kinetic energy (Ek). Kinetic energy, for an individual atom, can be calculated by the following equation where m is the mass, and u is the speed. How does temperature relate […]
