egoroff_w [7]

Answer:

The current is 0.248 A

Explanation:

Given that,

Inductor L= 45\times10^{3}\ H

Resistance R= 60\Omega

Voltage = 15 volt

Time t =7.0\times10^{-3}\ sec

We need to calculate the current

Using formula of current

I=\dfrac{V}{R}(1-e^{\dfrac{-R}{L}}t)

Where, V = voltage

R = resistance

L = inductance

T = time

Put the value into the formula

I=\dfrac{15}{60}(1-e^{\dfrac{-60}{45\times10^{3}}}\times7\times10^{-3})

I=0.248\ A

Hence, The current is 0.248 A.

Describe how an increase in humidity can affect the water cycle
anastassius [24]

An increase in humidity can strengthen the water cycle, because humidity is essentially boosted evaporation. When you have evaporation, that comes automatically with condensation and precipitation, so rain and cloud cover increases.

bekas [8.4K]
<h3><u>Answer;</u></h3>

Argon

<h3><u>Explanation;</u></h3>
  • Phosphorus is an element found in group 15 of the periodic table, it is one of the element that belongs to nitrogen family.
  • The element phosphorus exhibits allotrophy, namely; white phosphorus, red phosphorus and black phosphorus.
  • <u>Phosphorus, particularly the white phosphorus combines with oxygen so easily that it catches fire automatically. Thus, as a safety precaution, white phosphorus is stored under water in laboratories. </u>
  • <u>It may be also stored in argon, since argon is an inert element which belongs to the noble gases group.</u>

b) Assume the rod is 0.60 m long and has a mass of 0.50 kg, and the clay blob has a mass of 0.20 kg and moves at an initial velo
SOVA2 [1]

Answer:

The correct answer is "6.96 rad/s".

Explanation:

The given values are:

Length,

L = 0.6 m

Mass,

m₁ = 0.5 kg

m₂ = 0.2 kg

Initial velocity,

V = 8 m/s

Now,

The final angular velocity will be:

⇒ \omega =\frac{6m_1V}{(4m_1+3m_2)L}

By substituting the values, we get

⇒     =\frac{6\times 0.2\times 8}{(4\times 0.2+3\times 0.5)0.6}

⇒     =\frac{9.6}{1.38}

⇒     =6.96 \ rad/s
