How much current will pass through a 12.5 ohm resistor when it is connected to ta 115 volt source of electrical potential?

Physics

Marrrta [24]3 years ago

Answer:

9.2 amperes

Explanation:

Ohm's law states that the voltage V across a conductor of resistance R is given by V = R I

Here, voltage V is proportional to the current I.

For voltage, unit is volts (V)

For current, unit is amperes (A)

For resistance, unit is Ohms (Ω)

Put R = 12.5 and V = 115 in V=RI

115=12.5I\\I=\frac{115}{12.5}\\ =9.2\,\,amperes

When vibrational motion in an object increases, which is a true statement?
ss7ja [257]
Hello friend!!

We know that kinetic energy is the energy possessed due to the motion of the object. And we know if the object is in a fast motion then the temperature would be high, whereas if the object is slow in motion then it will have lower temperature. So we know that the kinetic energy is indirectly related to temperature.From our knowledge we can conclude that HIGHER THE TEMPERATURE, HIGHER THE KINETIC ENERGY and LOWER THE TEMPERATURE, LOWER THE KINETIC ENERGY.
Hence, the answer to your question here is,a.kinetic energy, temperature, and thermal energy increase. 
Hope it helps!!All the best!!

A 10 kg cart is rolling across a parking lot with a velocity of .5 m/s. What is its momentum?
-Dominant- [34]

Hello!

\large\boxed{p = 5  \text{ } kgm/s}

Use the equation for momentum:

p = mv

Plug in the given mass and velocity into the equation:

p = 10 * 0.5

p = 5 kgm/ s

A cyclist starts at rest and accelerates at 0.5 m/s2 south for 20 s. What is the cyclist’s final velocity
inn [45]

The cyclist's final velocity is 10 m/s.

From the question,

We are to determine the cyclist's final velocity.

<h3>Linear motion</h3>

From one of the equations of motion for linear motion, we have

v=u+at

Where

v is the final velocity

u is the initial velocity

a is the acceleration

and t is the time

From the given information,

The cyclist starts at rest, this means the initial velocity is 0 m/s

That is,

u = 0 m/s

Also

a = 0.5 m/s²

and t = 20 s

Putting the parameters into the equation, we get

v = 0 + 0.5 \times 20

v = 0 + 10

v = 10 \ m/s

Hence, the cyclist's final velocity is 10 m/s.
