A metal rod has a length of 123. cm at 200°C. At what temperature will the length be 92.6 cm if the coefficient of linear expans
mestny [16]

Answer:

\theta_{2} = 15400^0 C

Explanation:

The formula for linear expansivity, \alpha = \frac{l_{2} - l_{1}  }{l_{1} ( \theta_{2}  - \theta_{1} )}

original length, l₁ = 123 cm = 1.23 m

final length, l₁ = 92.6 cm =0.926 m

original temperature, θ₁ = 200°C

Linear expansivity, α = 2 * 10⁻⁵ °C⁻¹

Putting these values into the formula:

2 * 10^{-5}  = \frac{1.23 - 0.926  }{l_{1} ( \theta_{2}  -200 )}\\ \theta_{2}  -200 = \frac{0.304}{2 * 10^{-5} } \\\theta_{2} = 15200 + 200\\\theta_{2} = 15400^0 C

What will the transistor look like in the future
Elden [556K]

<u>TRANSISTOR:</u>

The future of transistors based on the ongoing researches suggests that, it would be based on nano technology. This technology is itself still under development and the case is similar in the case of transistors too.

Transistors due to their applications, especially its application as an amplifier has increased its usage and the dependability over them. The hard part often arises with the fabrication techniques which are being tested and developed as we speak in order to increase the efficiency of the transistors and also to reduce their physical size though, these would mean that, the design complications would be higher.

How many 50 mg tablets can be produced from 10 kg of ibuprofen?
miv72 [106K]

Answer:

2 × 10⁵

Explanation:

The total mass of the drug, ibuprofen = 10 kg

Kilograms and grams are related as:

1 kg = 1000 g

Also,

Grams and milligrams are related as:

1 g = 1000 mg

So,

1 kg = 10⁶ g

Mass of the drug, ibuprofen = 10 × 10⁶ mg = 10⁷ mg

Given, mass of tablet = 50 mg

So, number of tablets = total mass / Mass of 1 tablet = 10⁷ mg / 50 mg = 2 × 10⁵

<u>Number of 50 mg tablets =  2 × 10⁵</u>
