Did the Saturn V launch from the crawler?
Did the Saturn V launch from the crawler? The crawlers are unique in the world, having been built in 1965 to move the massive Saturn V rocket from Kennedy’s Vehicle Assembly Building to Launch Complex 39. After the Moon landing and Skylab programs ended, the crawlers continued their work, taking space shuttles to their launch […]
Where we can apply Bernoulli equation?
Where we can apply Bernoulli equation? Along a Streamline – Bernoulli’s equation can only be used along a streamline, meaning only between points on the SAME streamline. mixed jets, pumps, motors, and other areas where the fluid is turbulent or mixing. Why do we use Bernoulli equation? The Bernoulli equation is an important expression relating […]
What were the provisions of the Agricultural Adjustment Act?
What were the provisions of the Agricultural Adjustment Act? In 1933 a federal law from the New Deal era was put into place. This was the Agricultural Adjustment Act of 1933. The act reduced production by paying farmers subsidies to not plant on part of their land and to kill off excess livestock. This was […]
What is edge dislocation and screw dislocation?
What is edge dislocation and screw dislocation? An edge dislocation therefore moves in the direction of the Burgers vector, whereas a screw dislocation moves in a direction perpendicular to the Burgers vector. The screw dislocation ‘unzips’ the lattice as it moves through it, creating a ‘screw’ or helical arrangement of atoms around the core. Is […]
Which of the following is a pneumatic tool?
Which of the following is a pneumatic tool? Pneumatic tools are powered by compressed air. Common types of these air-powered hand tools that are used in industry include buffers, nailing and stapling guns, grinders, drills, jack hammers, chipping hammers, riveting guns, sanders and wrenches. How do you power a pneumatic tool? Pneumatic tools are powered […]
Why does one way synaptic transmission occur?
Why does one way synaptic transmission occur? One-way synaptic transmission is usually a chemical synapsis, where an electrical impulse is transmitted along the neuron’s axon until it reaches the axon terminals, then a depolarization of the presynaptic membrane occurs, leading to the liberation of neurotransmitter molecules from the synaptic vesicles (located in … Which component […]
Why Arduino Uno is better than other microcontroller?
Why Arduino Uno is better than other microcontroller? Inexpensive – Arduino boards are relatively inexpensive compared to other microcontroller platforms. Most microcontroller systems are limited to Windows. Simple, clear programming environment – The Arduino Software (IDE) is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. What type of […]
How does it follow the first law of thermodynamics?
How does it follow the first law of thermodynamics? The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. What is the main application of Hess’s law? Hess’ law […]
