Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is attractive, and the zero of potential energy is at infinite separation. This is a negative result if the force between the two charges is attractive (they are opposite) and positive if it is repulsive (the […]
What are run flat tires list three technologies that are being used in run flat technology?
What are run flat tires list three technologies that are being used in run flat technology? Today there are three technologies used as Original Equipment on vehicles to help maintain vehicle mobility when a tire is punctured. They are self-sealing tires, self-supporting tires and tires supported by an auxiliary system. Can you fix a slow […]
What math do meteorologists need?
What math do meteorologists need? Here’s a typical college list… calculus 1, 2, 3 and sometimes 4… differential equations… linear algebra… statistics… and a calculus based physics class and lab. Do you need to be good at math to be a meteorologist? Meteorologists need to be good at math and science, so take all the […]
How do you determine specific heat experimentally?
How do you determine specific heat experimentally? Steps to determine the specific heat capacity. Place a beaker on a balance and press zero. Now add the oil to the beaker and record the mass of the oil. Read the starting temperature of the oil. Connect a joulemeter to the immersion heater. Time for thirty minutes. […]
Is the electrical pressure that causes current to flow?
Is the electrical pressure that causes current to flow? “Volts” is the measure of “electrical pressure” that causes current flow. Voltage is sometimes referred to as the measure of a potential difference between two points along a conductor. Voltage is typically supplied by either a generator or battery. What is the relationship between voltage and […]
What temperature do crickets stop chirping?
What temperature do crickets stop chirping? Get Him to Chill. Ideal temperatures for raising crickets is between 82 to 86 degrees Fahrenheit, which also makes the best conditions for chirping. When temperatures in the cricket’s habitat fall below room temperature — 74 degrees — chirping slows and diminishes in intensity. What temperature is too cold […]
How do you find the side slope of a trapezoidal channel?
How do I know if my truss is statically determinate?
How do I know if my truss is statically determinate? A truss is considered statically determinate if all of its support reactions and member forces can be calculated using only the equations of static equilibrium. For a planar truss to be statically determinate, the number of members plus the number of support reactions must not […]
Do flaps increase stalling angle of attack?
Do flaps increase stalling angle of attack? Flaps change the camber of a wing such that more or less lift is created at the same angle of attack. Therefore, the wing’s stall angle of attack decreases with increasing flap deflection (the wing reference line from which the angle of attack is measured doesn’t change with […]
What are oil and gas facilities?
What are oil and gas facilities? An oil facility encompasses the equipment between the oil wells and the pipeline or other transportation system. The purpose of an oil facility is to make the oil ready for sale to the purchaser’s standards (maximum allowable water, salt, and other impurities). Why oil and gas industry is important? […]
