What is the final velocity in free fall? Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independent of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 […]
What is Biot Savart law and its application?
What is Biot Savart law and its application? The Biot Savart Law states that it is a mathematical expression which illustrates the magnetic field produced by a stable electric current in the particular electromagnetism of physics. This law is applicable in the magnetostatic estimate, & is reliable by both Gauss’s (magnetism) and Ampere’s (circuital) law. […]

Why is AC current used in homes?
Why is AC current used in homes? Why we use AC voltage in our homes despite DC voltage gaining traction. Simply put, AC voltage is capable of converting voltage levels with just a transformer, making it far easier to transport across great distance than DC, whose conversion requires more complex electronic circuitry. How do I […]

What are the three types of switching techniques?
What are the three types of switching techniques? There are 3 common switching techniques: Circuit Switching. Packet Switching. Message Switching. What are the four causes of packet delay? In packet switched networks, there are four types of commonly identified delays – processing, queuing, transmission and propagation delays. Processing delay is the CPU cycles needed to […]
What are 3 ways to prevent beach erosion?
What are 3 ways to prevent beach erosion? Since erosion is unavoidable, the problem becomes discovering ways to prevent it. Present beach erosion prevention methods include sand dunes, vegetation, seawalls, sandbags, and sand fences. What happens to a beach when a wave’s backwash is stronger than its swash? If the swash is stronger than the […]
