Explanation

(a) S.l unite for the intensity of a blackbody radiation = Wm-² OR Js\(^{-1}\)m-²

(b) Two features of the graph

i. The shape of the graph is non-symmetric.

ii. Peaks of the intensity have lower wavelengths/Peaks decrease with wavelength.

iii. The line joining the peaks have a negative gradient.

Correct Answer: C. 40N

Explanation

VR = 5:1 or 5

Load = 20kg or 200N

MA = \(\frac{200}{E}\)

Efficiency% = \(\frac{MA}{VR} * 100\)

100% = \(\frac{200}{5E} * 100\)

5E = 200

E = 40

Correct Answer: D) trypsin

Explanation

The question is asking about a digestive enzyme that causes proteins in milk to coagulate. Coagulation is the process of forming a clot or a thickened mass. The options given are ptyalin, pepsin, rennin, trypsin, and amylase. Ptyalin is a digestive enzyme found in saliva that breaks down carbohydrates into simple sugars. Pepsin is a digestive enzyme found in the stomach that breaks down proteins into smaller peptides. Trypsin is another digestive enzyme that breaks down proteins in the small intestine. Amylase is a digestive enzyme that breaks down starch into sugars in the small intestine. Rennin, on the other hand, is the digestive enzyme responsible for coagulating proteins in milk. It is primarily found in the stomach of young mammals and helps to digest the milk they consume. In humans, rennin production decreases as we age and is replaced by other digestive enzymes. Therefore, the correct answer to this question is option C: rennin. It is important to note that this enzyme is specific to milk and is not involved in the digestion of other proteins.

Correct Answer: C. organized laws

Explanation

In order for an area to be considered a state, it must have a permanent population, a defined territory, a government and sovereignty.

Correct Answer: B) order, delivery note, invoice, debit note and statement

Explanation

To understand the correct order, let's look at the options provided.

Option A suggests the order as: debit note, order, delivery note, invoice, and statement. However, this is not the correct order.

Option B suggests the order as: order, delivery note, invoice, debit note, and statement. This is the correct order.

Option C suggests the order as: statement, order, invoice, delivery note, and debit note. This is not the correct order.

Option D suggests the order as: invoice, order, statement, debit note, and delivery note. This is not the correct order.

Therefore, the correct answer is Option B: order, delivery note, invoice, debit note, and statement.

In a business transaction, the order is placed first, followed by the delivery note to confirm the goods delivered, then the invoice is sent to request payment, after which a debit note may be issued for adjustments, and finally, a statement may be sent to summarize the transactions.

Remember, it's important to follow the correct order of these documents to ensure smooth and accurate business transactions

Correct Answer: B. marketing concept

Correct Answer: B. console the addressee

Correct Answer: D. Open-mindedness

Explanation

From the given options, Open-mindedness is not a specific step in the scientific method. Open-mindedness is a general mindset that scientists should have throughout the entire process. It involves being receptive to new ideas, evidence, and interpretations, which helps scientists avoid biases and reach more accurate conclusions.

Correct Answer: C. u = \(\frac{2x + 3}{2 - 3x}\)

Explanation

x =\(\frac{2u-3}{3u + 2}\)

cross multiply

x(3u + 2) = 2u - 3

3ux + 2x = 2u - 3

collect like terms of u

2x + 3 = 2u - 3ux

\(\frac{2x + 3}{2 - 3x}\) = u

Correct Answer: A. [Ar]4s23d6
