What are the 4 main components of hydraulic and pneumatic systems? Students learn about the fundamental concepts important to fluid power, which includes both pneumatic (gas) and hydraulic (liquid) systems. Both systems contain four basic components: reservoir/receiver, pump/compressor, valve, cylinder. What is the main difference between a hydraulic and a pneumatic machine? Pneumatics use an […]
How do you calculate the work input?
How do you calculate the work input? Calculate the work input in a pulley by using the previous readings in the correct mathematical equation: Work (W) equals force (f) multiplied by distance (d), or W=fd. The work done by the pulley is the equation of weight (w) multiplied by height traveled (h). What are 5 […]
Why does chlorine have 2 valence electrons?
Why does chlorine have 2 valence electrons? The atomic number of chlorine is 17. Hence it has 2 electrons in its inner-most shell, 8 electrons in its second shell and 7 electrons in outer-most shell respectively. Electrons in the outer shells that are not filled are called valence electrons. Hence it has got 7 electrons […]
What is speed and velocity quizlet?
What is speed and velocity quizlet? Velocity is speed in a given direction; speed and direction of a moving object. Like displacement, velocity is a vector. The slope of a distance versus the time graph represents speed; that is the rate that distance changes in relation to time. What is the relationship between velocity and […]
What happens when you mix hydrochloric acid and zinc?
What happens when you mix hydrochloric acid and zinc? When zinc reacts with hydrochloric acid, the reaction bubbles vigorously as hydrogen gas is produced. The production of a gas is also an indication that a chemical reaction is occurring. Zinc reacting with hydrochloric acid produces bubbles of hydrogen gas. What happens when you add zinc […]
Are the insides of glow sticks toxic?
Are the insides of glow sticks toxic? The ingredients in glow sticks are generally non-toxic, and most cases will not require medical attention. However, if glow stick fluid is swallowed, it may cause an upset stomach and some mouth irritation. Can you wash off glow stick liquid? The contents are not toxic, but a broken […]
What is the relationship between surface area and terminal velocity?
What is the relationship between surface area and terminal velocity? The position in which the object falls changes the surface area and in turn changes the terminal velocity. If the object has a greater surface area it will have more room for air resistance to work on it. There will be a greater upward force […]
What three things can happen when a wave hits a boundary?
What three things can happen when a wave hits a boundary? When a wave hits a boundary, the wave either reflects, refracts, or diffracts. How many ways can a wave change at a boundary? There are essentially four possible behaviors that a wave could exhibit at a boundary: reflection (the bouncing off of the boundary), […]
Why did we declare war on Japan?
Why did we declare war on Japan? On this date, President Franklin Delano Roosevelt, addressing the nation in a Joint Session in the House Chamber, asked Congress to declare war against Japan in response to the surprise attack against American naval facilities in and around Pearl Harbor, Hawaii, a day earlier. … Is Japan allowed […]
