Why would an counductor heat up soup?

1 answer:

6 0

example of a great insulator is a thermos. If you put soup in a thermos, you can open it later and enjoy warm soup on a cold winter day. The thermos insulates the soup, trapping the heat inside. Likewise, if you are playing soccer on a hot August afternoon, your thermos full of ice water stays refreshing and cold.

In electronics, the formula V = IR is called Ohm's Law. It gives the relationship in a circuit between the voltage V (in volts),

Tomtit [17]

Answer:

3+2i ohm.

Explanation:

Here we have a complex number operation. According to Ohm's law V=I*R, so:

$R=\frac{V}{I}\\\\R=\frac{21+i}{5-3i}$

we need to remove the complex number on the denominator, so we have to multiply by its complement on both side

$R=\frac{21+i}{5-3i}*\frac{5+3i}{5+3i}$

that gives us:

$R=\frac{102+68i}{34}=3+2i$

Velocity differs from speed in that velocity indicates a particle's __________ of motion. Enter the letter from the list given i

nexus9112 [7]

Before solving this problem first we have to understand the basic of velocity and speed.The speed is a scalar quantity which means the rate of change of distance covered by a particle .As the distance traveled is a scalar quantity as it has no specific directions,so is the speed.It has simply magnitude.

then we have to understand the velocity.Velocity is a vector quantity.IT is defined as the rate of change displacement of the particle or we may say the speed in a given direction .As we know that displacement is the minimum distance traveled by a particle which is nothing else except the straight line joining two points,so it has direction.hence velocity has a magnitude as well as direction.one has remember that the magnitude velocity is always smaller than or equal to the speed $velocity\leq speed$

so the answer will be DIRECTION i.e velocity indicates the direction of motion .
