tan 60° = (2kλ? /y? )/ (2kλ? /x? )

(√3λ? /x? ) = (λ? /y? ); √3λ? y? = λ? x?

d = Rsin 60°

⇒ d = (mv√3)/ (qB 2) = (√3v)/ (2aB)

$E=\frac{\text{Energy}}{\text{time}*\text{Area}}\Rightarrow \left[E\right]=\frac{\left[\text{Energy}\right]}{\left[\text{time}\right]\left[\text{Area}\right]}=\frac{M{L}^2{T}^{-2}}{L^{2}T}$

$\left[E\right]=M{L}^0{T}^{-3}$

  $\boxed{I=\frac{E}{R_2}}$

$U_{Inductor}=Heatlossin{R}_1=\frac{1}{2}L{\left(\frac{E}{R_2}\right)}^2$              

The time period of LC oscillations,

  $T=2\pi \sqrt[]{LC}$          

The time at which charge on the capacitor will be zero is  $\frac{T}{4}.$  

So t    $=\frac{\pi }{2}\sqrt[]{LC}$

There are various types of enzymes, including lyases, ligases, isomerases, hydrolases, oxidoreductases, etc. To know about the types of enzymes in detail, refer to the article.

Enzymes found in human bodies are 

• Lipases: They remove the fats in the gut.

• Amylase: It is present in the saliva. The role of amylase is to break down carbohydrates.

• Maltase: These enzymes are found in the small intestine. It breaks down the sugar maltose into glucose. 

• Trypsin: These enzymes are present in the small intestine. The function of trypsin is to break proteins into amino acids.

• Lactase: The function of lactase is to break down lactose into simpler sugars (glucose and galactose). Lactose is the sugar that is found in dairy products.

We can define enzymes as biocatalysts. It is important in biological processes like digestion, metabolism, and the synthesis of cellular components. If enzymes stop their functions, then the body can not generate enough proteins, which is important for survival. The examples of enzymes are lactase and amylase.

If the multimeter shows zero or low resistance reading for forward bias and does not change even on reversing the connection then the diode is defective. It is short.

If the diode shows a high resistance under both forward and reverse biased conditions, it is defective. It is open.

If the multimeter shows zero or low resistance reading for forward bias and shows high resistance reading on reversing the connection then the diode is not defective.
