Find the net force and acceleration. 15 points. Will give brainliest!

gladu [14]

Answer:

$\boxed{F_{net} = 28.7 \ N}$

$\boxed{a = 2.1 \ m/s^2}$

Explanation:

Finding the net force:

Firstly , we'll find force of Friction:

$F_{k} = (micro)_{k}mg$

Where $(micro)_{k}$ is the coefficient of friction and m = 13.6 kg

$F_{k} = (0.16)(13.6)(9.8)\\$

$F_{k} = 21.32 \ N$

Now, Finding the net force:

$F_{net} = F - F_{k}\\F_{net} = 50 - 21.32\\$

$F_{net} = 28.7 \ N$

Finding Acceleration:

$a = \frac{F_{net}}{m}$

$a = \frac{28.7}{13.6}$

$a = 2.1 \ m/s^2$

what is the energy efficiency of a coal burning power plant, and incandescent light bulb and the electrical transmoission lines

vlabodo [156]

the energy efficiency of a coal burning power plant is 33% and incandescent light bulb is only 10% and the electrical transmission lines between the power plant and the house is 70 %.

<h3>What is energy Efficiency?</h3>

The definition of energy efficiency is the use of less energy to carry out an activity or achieve a goal. Homes, buildings, and manufacturing facilities that use less energy to manufacture things require less energy to heat, cool, and operate appliances and gadgets.

One of the simplest and most economical methods to slow climate change, lower consumer energy bills, and boost the competitiveness of American businesses is via energy efficiency. In order to achieve net-zero emissions of carbon dioxide through decarbonization, energy efficiency is also a crucial factor.

that the average efficiency of coal-fired power plants around the world today is 33 percent.

an incandescent bulb is only 10% efficient.

the electrical transmission lines between the power plant and the house is 70 %.

An inductor has inductance of 0.260 H and carries a current that is decreasing at a uniform rate of 18.0 mA/s.

nignag [31]

Answer:

The self-induced emf in this inductor is 4.68 mV.

Explanation:

The emf in the inductor is given by:

$\epsilon = -L\frac{dI}{dt}$

Where:

dI/dt: is the decreasing current's rate change = -18.0 mA/s (the minus sign is because the current is decreasing)

L: is the inductance = 0.260 H

So, the emf is:

$\epsilon = -L\frac{dI}{dt} = -0.260 H*(-18.0 \cdot 10^{-3} A/s) = 4.68 \cdot 10^{-3} V$

Therefore, the self-induced emf in this inductor is 4.68 mV.

I hope it helps you!
