I would rather be hit by the deflated ball because it wouldn't hurt as bad because it wouldn't have a lot of weight to hurt me in anyway

A coil is connected in series with a 12.6 kΩ resistor. An ideal 65.2 V battery is applied across the two devices, and the curren

ivolga24 [154]

To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.

PART A)

$i = i_0 (1-e^{-t/T})$

$i = (V/R)(1-e^{-t/T})$

$0.00402 = (65.2/12600)(1-e^{-0.00402/T})$

$T = 0.002679s$

$T = L/R$

Inductance can be defined then,

$L = RT$

$L = (12600)(0.002679)$

$L = 33.75H$

PART B) Now the energy is given under the terms:

$E = \frac{1}{2}Li^2$

$E = \frac{1}{2} (33.75)(0.00402)^2$

$E = 0.0002727J$

Therefore the energy stored in the coil at this same moment is 0.0002727J

You have a device that takes temperature measurements and runs off of solar power. How often it is programmed to take a measurem

Tcecarenko [31]

Answer:

In the Equator:

As far as the temperature is concerned equator is more or less the same throughout the year, however, there are some fluctuations also, I will set this device in March and September because, in this month, the Sun is exactly over the equator and I would be able to get the more results in this month.

In Antarctic:

As far as the climatic conditions of Antarctic are concerned, it is all the same while it fluctuates in December because the Sun is very much close to Antarctic that's why I will choose this month.

Given velocity, what is the formula for acceleration?

Bogdan [553]

Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2).
