Will this object move by itself? Objects do not move on their own. If they are in motion they were initially moved by a force, either from their initial development as an object or by an outside force that initially moved them to motion. Yet, the atoms and smaller particles of objects are always in […]

What is maximum data rate of channel? Higher data rates are expressed as Kbps (“Kilo” bits per second, i.e.1000 bps), Mbps (“Mega” bits per second, i.e.1000 Kbps), Gbps (“Giga” bits per second, i.e. 1000 Mbps) and Tbps (“Tera” bits per second, i.e. 1000 Gbps). One of the main objectives of data communications is to increase […]

Does a spoiler decrease speed? The drag and wind resistance decreases speed instead of increasing it. Spoilers are accessories, like tails, that extend off the trunk of the vehicle, ‘spoiling’ the airflow. The rear spoiler basically interrupts the flow and redirects it for reduced drag. Does a spoiler improve gas mileage? Does a spoiler help […]

Is a compass needle an induced magnet? The compass reacts with the earth’s poles to point in the direction of the earth’s North Pole. Rubbing the magnet against the needle in one direction caused the iron atoms in the object to line up and create a weak magnetic field, which made the needle behave like […]

Which ground will the ball bounce higher on the ground without grass or on the ground with grass? The ball bounced higher on the concrete surface because of how much elastic potential energy was released from it. Since the concrete surface is the hardest surface, it allowed more energy to be released from the ball, […]

What are the norms and values of a culture? Cultural norms are sets of behaviors and beliefs shared by members of a society or group of people. Cultural norms are typically transmitted by government, educational and family social systems. Members of a culture are often expected to conform to the norms of the greater culture. […]

What is the main principle of GPS? The GPS system consists of three “segments” called the Control Segment, the Space Segment, and the User Segment. Proper operation of each of these three segments results in accurate, reliable operation of the entire system. Is the key principles used in GPS system? The working/operation of the Global […]

What happened to Theia? The model also assumed that the mantle of the theorized planet Theia was rich in iron, making it extremely dense. In their model, Theia winds up mostly destroyed, with pieces flung into space to create the moon, and much of its mantle breaking into fragments, which make it all the way […]

How do you make an RCC building earthquake resistant? Another method to reduce failure during earthquakes is to design a strong core shear wall in seven to 20 storey RCC structures. Typically, this is designed in the elevator area. If the shear wall is designed as per relevant code, it can provide necessary stiffness to […]

Can I reverse a transformer? When a transformer is reverse fed, the taps move to the output side and so their operation is reversed. For reverse fed applications, raising the taps will increase output voltage and lowering the taps will lower output voltage. What is the difference between step up transformer and step down transformer? […]
