Correct Answer: B. has low capillarity

Explanation

(a) Einstein's photoelectric equation is

E = W + K Emax, where

E = Energy of incident radiation

W = Work function

K.E\(_{\text{max}}\) = Maximum kinetic energy of photoelectron.

(b) For photocell factors responsible for:

(i) Emission \(\to\) frequency or wavelength of incident radiation.

(ii) Rate of emission \(\to\) intensity of incident radiation or number of photons.

(iii) Energy of photoelectrons ---> frequency or wavelength of incident radiation.

(c)(i) (\(\alpha\)) 218 + q = 222

q = 4

(\(\alpha\)) P = 84 + 2 = 86,

m = 214 — 214 = 0

n = 83 — 84 = —1

x is an electron or beta particle.

ii) Needs to safely dispose radioactive waste:

(1) it emits harmful radiations.

(2) it is toxic

(d)(i) E = \(\frac{hc}{\lambda}\)

= \(\frac{6.6 \times 10^{-34} \times 3.0 \times 10^{8}}{2.4 \times 10^{8}}\)

= 8.25 x 10\(^{-19}\)J

(ii)

E\(_4\) ----------------- - 6.0 x 10\(^{-19}\)J

E\(_3\) ---------------- - 8.2 x 10\(^{-19}\)J

E\(_2\) ---------------- - 8.8 x 10\(^{-19}\)J

E\(_1\) ---------------- - 16.7 x 10\(^{-19}\)J

The energy level transitions which cause the emission of the photon in (d)(i) is. E\(_3\)

Correct Answer: D) steal, kill and destroy

Explanation

This question is asking about how the thief is described by Jesus. According to the options provided, we are to choose the correct order of the three things that the thief comes to do. The options are:

Option A: destroy, kill and steal

Option B: destroy, steal and kill

Option C: kill, destroy and steal

Option D: steal, kill and destroy (Correct)

The correct answer is option D, which states that the thief comes to steal, kill and destroy. This description was given by Jesus in John 10:10.

It is important to note that Jesus was using this analogy to describe the work of the devil, who comes to steal, kill, and destroy human lives. This means that the devil is always seeking to harm people and destroy their lives.

As Christians, we should be aware of this and be vigilant so that we do not fall into the devil's traps. We should also put on the whole armor of God, as described in Ephesians 6:10-18, to protect ourselves from the devil's attacks.

In summary, the correct order of the three things that the thief comes to do, as described by Jesus, is to steal, kill, and destroy. This is a metaphor for the work of the devil, who seeks to harm people and destroy their lives. As Christians, we should be aware of this and be prepared to protect ourselves from the devil's attacks.

Correct Answer: C. n-type

Correct Answer: C) it decreases

Correct Answer: B. 162.5m

Correct Answer: B. 63°

Correct Answer: C. 3/4

Explanation

(a) Young's modulus of electricity is the ratio of tensile or compressive stress to tensile or compressive strain.

(b) F = Ke

K = \(\frac{f}{e} = \frac{20}{(10.01 - 10.00)^{-2}}\)

= 2.0 x 10 N/M

Correct Answer: D) nitric acid to sodium hydroxide

Explanation

A neutralization reaction is a chemical reaction between an acid and a base, which results in the formation of a salt and water. In this case, the correct answer isOption D: nitric acid to sodium hydroxide.

Nitric acid (HNO₃) is an acid, and sodium hydroxide (NaOH) is a base. When they react together, they produce a salt (sodium nitrate, NaNO₃) and water (H₂O). The balanced chemical equation for this reaction is:

\[ HNO_3 + NaOH \rightarrow NaNO_3 + H_2O \]

The other options do not represent neutralization reactions:

Option A involves converting one acid (nitric acid) to another acid (hydrochloric acid), which is not a neutralization reaction.

Option B involves converting one acid (nitric acid) to another acid (sulphuric acid), which is also not a neutralization reaction.

Option C is incomplete, as it only mentions nitric acid and distilled water, but does not mention a base.

Option E involves sodium chloride (a salt) and distilled water, but does not involve an acid and a base reacting together.

In summary, neutralization reactions involve an acid and a base reacting together to produce a salt and water. In this question, only Option D represents a neutralization reaction.
