Answer:

An electrical current is an electrical charge flowing around a circuit. Carried by billions of tiny particles called electrons, the charge is already in the wires.

Explanation:

There are three basic conditions for the electric current flow is to be given below:-

The loop must be shuttered where current throws occur.

There must be some possible distinctions in the chain.

The medium in which current flows will be a conductor (but flow in the semiconductor at a higher temp. current).

<h3>What is Supernova?</h3>

A supernova is a star's tremendous and brilliant explosion. It is referred to as a supernova or a supernovae and is abbreviated as SN or SNe.
This fleeting astronomical occurrence takes place either when a white dwarf is set off into uncontrolled nuclear fusion or during the latter phases of the development of a big star. The original object, known as the progenitor, either disintegrates completely or falls into a neutron star or black hole.
Before fading over the course of several weeks or months, the peak optical luminosity of a supernova can be similar to that of an entire galaxy.
Compared to novae, supernovae are more energetic. Nova, which in Latin means "new," refers to what appears to be a transitory new bright star in astronomy. Supernovae can be distinguished from regular novae by the prefix "super-."

In some applications of ultrasound, such as its use on cranial tissues, large reflections from the surrounding bones can produce

worty [1.4K]

Answer:

b. 0.75 mm

Explanation:

The distance between antinodes d is half the wavelength $\lambda$ . We can obtain the wavelength with the formula $v=\lambda f$ , where f is the frequency given ( $f=1MHz=1\times10^6Hz$ ) and v is the speed of sound in body tissues (v=1540m/s), so putting all together we have:

$d=\frac{\lambda}{2}=\frac{v}{2f}=\frac{1540m/s}{2(1\times10^6Hz)}=0.00077m=0.77mm$

which is very close to the 0.75mm option.

Does a car accelerate when it goes around a corner at a constant speed?

Evgen [1.6K]

Yes, it does. Acceleration is defined as the rate of change of velocity. Velocity is the rate of change of position with a given direction i.e. speed with direction.So even though the speed of the turning car is constant the velocity is not. This means that the velocity is changing, and the rate of change of velocity is called acceleration. Hence, the car is accelerating.

Algorithm to determine number of shortest paths between two nodes

Lunna [17]

Search Results<span>Use BFS to determine the length of the shortest v-w-path. Then use DFS to find thenumber of the v-w-shortest paths such that two nodes are connected and the length of path equals to the output of BFS. But the running time of this plan is O(m+n)+O(m+n). Also I've tried to modify the Dijkstra algorithm.</span>
