A blender with a total resistance of 6 ohms runs on a voltage of 190 volts. How much current does it use? NEED TO KNOW ASAP PLEA

faltersainse [42]

<h2>Hello!</h2>

The answer is 31.67 Amps.

To solve the problem, we need to use Ohm's Law equation, which states that:

$V=IR$

Where,

V, is the voltage (in volts)

I, is the current (in Amps)

R, is the resistance (in Ohms)

We are given the following information:

$Voltage=190v\\Resistance=6\Omega\\$

So, using Ohm's Law equation and substituting the given information, we have:

$V=IR\\\\190v=I*6\Omega\\\\I=\frac{190v}{6\Omega}=31.67Amps$

Hence, we have that the current used by the blender is 31.67Amps.

Have a nice day!

A snowboarder starts from rest on an inclined planar snow surface and gives herself a tiny push to start sliding down the hill.

tiny-mole [99]

Answer:

v = 26.52 m/s

Explanation:

Here we know that as she passes the flag she will gain some speed

so here we can say that

Work done by all forces = change in kinetic energy of the system

so we will have

$W_g + W_f = \frac{1}{2}mv_f^2 - \frac{1}{2}mv_i^2$

here we know that

$W_g = mgh$

$W_f = -\mu mg d$

$v_i = 0$

h = 39.78 m

d = 27.81 m

so we have

$mgh - \mu mg d = \frac{1}{2}mv^2 - 0$

$(9.8)(39.78 - (0.14)(27.81)) = \frac{1}{2} v^2$

$v = 26.52 m/s$

An atomic nucleus is composed of A) protons. B) protons and neutrons. C) protons and electrons. D) protons, neutrons, and electr

In-s [12.5K]

Answer:

B) protons and neutrons.

Explanation:

The protons and neutrons are located in the nucleus of the atom and represent most of the 'mass' of the atom, that's their count that determine the 'mass' of an atom (like 12 for Carbon).

The electrons rotate around the nucleus and have a negligible mass.

If the core of jupiter is 30,000 celcius and it is five times hotter than the sun, what's the temperature of the surface of the

VMariaS [17]

Let, the temperature of Sun's surface = c

So, 5c = 30, 000
c = 30,000 / 5
c = 6,000

In short, Your Answer would be 6000

Hope this helps!
