Answer:

As voltage increases, current increases and resistance stays the same .

Explanation:

Ohm's law gives the relationship between the voltage, resistance, and current. The mathematical form of Ohm's law is given by :

$V\propto I\\\\V=IR$

R is resistance

I is current

V is voltage

So, as voltage increases, current increases and resistance stays the same. The correct option is (A).

<h2>Answer : </h2>

20cm spanner is suitable to open this nut , Because we feel easy to apply force at the end of spanner to rusted nut. It means that as the perpendicular distance between force and axis of rotation increase the magnitude of moment also increase.

I think the Answer will helps you.....

There is a maximum depth at which a diver can breathe through a snorkel tube because as the depth increases, so does the pressur

hammer [34]

Answer: $59.78\times 10^3\ Pa$

Explanation:

Given

Diver is at a depth of $h=6.1\ m$ inside the water $(\rho=10^3\ kg/m^3)$

As we go down pressure increases due to the weight of liquid column above us

Pressure difference is given by $P=\rho \times g \times h$

Where $\rho$ =density of liquid

h=depth

g=acceleration due to gravity

So external-internal pressure difference is

$\Delta P=10^3\times 9.8\times 6.1$

$\Delta P=59.78\times 10^3\ Pa$

Explain the difference between how intrusive and extrusive igneous rock form and how those formation processes affect the minera

rusak2 [61]

Extrusive molten rocks are formed from lava while the intrusive molten rocks are formed from magma.

<u>Explanation:</u>

Extrusive molten rocks originate from lava, framing at the outside of the Earth and cooling rapidly, which means they structure little precious stones. Intrusive volcanic rocks originate from magma, shaping profound underground and taking more time to cool, which means they structure bigger crystals.

Intrusive molten rocks are framed when magma cools gradually underneath the surface, while extrusive rocks are shaped when magma cools quickly at the surface.

How do amplitude and frequency affect light energy? help asap !!!!!!

Lubov Fominskaja [6]

So, I’m assuming that we’re treating light as a propagating wave.

Amplitude measures the amount of energy transported by a wave, thus amplitude squared is directly proportional to the light’s energy. The higher the amplitude, the higher the energy.

Energy is also directly proportional to the frequency of a wave, the higher the frequency, the higher the energy.

I took my second answer from the formula below:
