Emily sprains her ankle on her way home from school. Her mom suggests she use an “instant cold pack” to reduce the swelling. Whe

n Emily’s mom hands her the cold pack, it is room temperature. The instructions on the pack tell Emily to pop a button inside the ice pack to open a packet of chemicals. Once Emily has popped the button, she notices that the cold pack immediately gets cold. She places it on her swollen ankle. Write a thoughtful and complete response (3+ sentences) that describes what happened to the energy as it is first in the cold pack (before Emily pops the button), then when she pushes the button, and then after Emily has placed the cold pack on her ankle. Discuss transfers and transformations of the energy.

For a certain RLC circuit the maximum generator EMF is 125 V and the maximum current is 3.20 A. If le a) the impedance of the ci
MAXImum [283]

Answer:

Part (i)

Z = 39.06 ohm

Part (ii)

R = 21.7 ohm

Explanation:

a) here we know that

maximum value of EMF = 125 V

maximum value of current = 3.20 A

now by ohm's law we can find the impedence as

z = \frac{V_o}{i_o}

now we will have

z = \frac{125}{3.20} = 39.06 ohm

Part b)

Now we also know that

\frac{R}{z} = cos\theta

\theta = 0.982 rad = 56.3 degree

now we have

\frac{R}{39.06} = cos56.3

R = 21.7 ohm

Which of the following explains why international travelers need to use special adapters when plugging a device designed to oper
Darina [25.2K]

Answer:

The answer is: The increased voltage causes an increase in power usage, and the device will over-heat.

Explanation:

First, we must consider the variables of the electrical system that will allow us to respond. In this case, power, current and voltage, which are related by

P=VI

Where P=Power, V=Voltage, I=Current.

In the equation it can be observed that power is directly proportional to the system voltage. Thus, if the voltage increases as in this case, the power will also increase, which overheats the device and can cause damage to it.
