What are the dimensions of the quantity? The dimension of a physical quantity is defined as the powers to which the fundamental quantities are raised in order to represent that quantity. The seven fundamental quantities are enclosed in square brackets [ ] to represent its dimensions. What are the dimensions of the quantity 1? The […]
How strong is tuff rock?
How strong is tuff rock? Tuff rock has geotechnical properties such as 18-25 kN/m3 of unit weight, 1.5 – 2.4 gr/cm3 of bulk density, 2.29 – 2.64 gr/cm3 of particle density, highly varied compressive strength depending on the degree of weathering, 0 – 1.45 MPa of cohesion, friction angle = 24° – 45° of friction […]

What are the requirements of database?
What are the requirements of database? In the spirit of David Letterman’s Top Ten lists, here is a look at what IT management requires from database management systems (DBMSs). System-Level Data Recovery. Application-Level Data Recovery. Application Data Availability. Multi-Level Data Security. Application Performance. Scalability: Users, Transactions, Data. What are the requirements of relational model? Best […]
When electric field is applied on the ends of a conductor the free electrons start moving in direction?
When electric field is applied on the ends of a conductor the free electrons start moving in direction? These free electrons inside the conductor move randomly and frequently collide with heavier atoms and change their direction of motion every time. When a steady electric field is applied to the conductor, the electrons start moving towards […]
What is the difference between a force multiplier and a distance multiplier?
What is the difference between a force multiplier and a distance multiplier? Levers can be force multipliers, when they increase the force that is put in (the effort). They can be distance multipliers if they make the load move further than the effort. The amount the force or distance is multiplied depends on the distances […]
What are two types of electric current?
What are two types of electric current? Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. Is gold good conductor? Gold is used as a contact metal in the electronics […]
How does a fan convert energy?
How does a fan convert energy? (The fan’s blades move air around the room. The kinetic energy of the moving blades does work in moving air through the fan blades.) The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.) What does a fan do to […]
What is P-type semiconductor with example?
What is P-type semiconductor with example? A p-type semiconductor is a type of semiconductor. When the trivalent impurity is added to an intrinsic or pure semiconductor (silicon or germanium), it is said to be a p-type semiconductor. Trivalent impurities such as boron (B), gallium (Ga), indium (In), aluminium (Al) etc. are called acceptor impurity. Is […]
What happens if gas pressure is too high?
What happens if gas pressure is too high? High gas pressure can be just as bad for your furnace. That’s because it greatly increases the risk of furnace overheating. When this happens, all manner of internal components may become damaged by the excessive heat. What are four factors that determine the efficiency of a furnace? […]
