What does it mean if forces are in equilibrium? If the size and direction of the forces acting on an object are exactly balanced, then there is no net force acting on the object and the object is said to be in equilibrium. Because the net force is equal to zero, the forces in Example […]
Are all Cessna high wing?
Are all Cessna high wing? High wing aircraft are aircraft whose wings are mounted above the fuselage. The Cessna 172 is one of the most common high wing general aviation planes. What is the purpose of dihedral wings? Dihedral is the upward angle of an aircraft’s wings, which increases lateral stability in a bank by […]
Which version of Catia is best?
Which version of Catia is best? It was initially developed for use in designing the Dassault Mirage fighter jet. Nowadays, the most widely used version is CATIA V5, with CATIA V4 still being used in some industries, mostly in conjunction with V5. What companies use Catia? Many automotive companies use CATIA to varying degrees, including […]
How do you reach someone who is struggling?
Which is more important precision or recall?
Which is more important precision or recall? Recall is more important than precision when the cost of acting is low, but the opportunity cost of passing up on a candidate is high. What does precision recall tell us? A precision-recall curve helps to visualize how the choice of threshold affects classifier performance, and can even […]
How do you find n when given wavelength?
How do you find n when given wavelength? Re: Determining values of n given the wavelength So you are given a wavelength of 102.6 nm which will need to be converted to 102.6 x 10^-9 m. Using that wavelength, you can find the frequency of the radiation through the equation c=(wavelength)(frequency) where c is the […]
What happens when water vapor is warmer and less dense?
What happens when water vapor is warmer and less dense? Water condenses whenever water vapor cools to a temperature lower than the point when evaporation occurs. Condensation happens near the ground when warm, humid air meets cooler land or water to create fog, which is like clouds that accumulate at ground level. What happens to […]
Which of the following is an example of radiant energy?
Which of the following is an example of radiant energy? Virtually anything that has a temperature gives off radiant energy. Some examples of radiant energy include: The heat emitted from a campfire. Emission of heat from a hot sidewalk. What is radiant energy also called? Radiant energy, also known as electromagnetic radiation (EMR), is energy […]
Where in a fluid vorticity is generated?
Where in a fluid vorticity is generated? Vorticity is generated at boundaries by the relative acceleration of fluid and wall. In a homogeneous fluid, vorticity is generated only at boundaries and its generation is instantaneous and the result of inertial forces. What is absolute relative and vorticity? RELATIVE VORTICITY: the counter-clockwise (CCW) or clockwise (CW) […]
Does a negative acceleration mean an object is slowing down?
Does a negative acceleration mean an object is slowing down? An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. Can a body have 0 velocity and still be accelerating example? Yes, a body with a velocity 0 can still accelerate. The simplest example is a […]
