BPSC TGT Math & Science Mock Test - 10 - Bihar PGT/TGT/PRT MCQ

Conjunction of time is used.

The sentence refers to an action that was done in the past (last night) hence; the correct answer is the simple past tense of the verb 'finished'.

The correct indefinite pronoun to fill in the blank in the given sentence is "anyone." Here's the explanation:
1. Analysis of the sentence:
The sentence is asking whether someone has finished the work. It is seeking an indefinite pronoun to represent an unspecified person.
2. Understanding the options:
Let's analyze each option to determine the correct one:
- Option A: anyone - This pronoun refers to any person, indicating that it could be someone who has finished the work.
- Option B: few - This pronoun refers to a small number of people, but it does not specify whether anyone has finished the work.
- Option C: many - This pronoun refers to a large number of people, but it does not indicate whether anyone has finished the work.
- Option D: none - This pronoun indicates that no one has finished the work, which contradicts the question.
3. Selecting the correct option:
Based on the analysis, we can conclude that the correct option is A: anyone. It is the only option that fits the context of the question, as it represents an unspecified person who may have finished the work.
Thus, the correct answer is option A: "anyone."

Opium is the dried latex obtained from the opium poppy

Hence, Option C is correct.

Hong Kong and Macau are two special administrative regions in China that enjoy a high degree of autonomy. They have separate legal and economic systems, different from the mainland.

There are 366 days in a leap year, i.e, 1 more than a normal year.

Now, 52 weeks make up 344 days (52 x 7 = 344)
That means that we already have 52 sundays for sure.

Then, we are left with 2 days. Now, these days can be any from a pair of- mon-tues,tues-wed,wed-thurs,thurs-fri,fri-sat,sat-sun,sun-mon. Here favourable cases are sat-sun and sun-mon i.e, 2 cases and total number of cases is 7.

So, Probability=number of favourable cases/Total number of cases.

Therefore, Probability= 2/7.

l=a+(n-1)d , d=109-114=-5
First negative term will be
0 > a+(n-1)d
0 > 114+(n-1)(-5)
0 > 114-5n+5
5n > 119
n > 119/5=23.8
So the first negative term will be 24th term.

We have an AP :10.0, 10.5, 11.0, 11.5
Where a=10, d=0.5
l=a+(n-1)d
 =10+(11-1)0.5
 =10+5=15

Let one root be α then other root will be 3α.
∴ Sum of the roots

And Product of the roots 

Equating the coefficients of α² and subtracing e.q. (ii) from e.q. (i), we get

Let the radius of the circle be rr and side of the square be a. Then, according to question,

Now, ratio of their areas, 

Given: Angle of elevation θ = 60°
Let the height of the tower AB be hmeters.
And the length of the shadow BC is 30 meters.

Therefore the hieght of the tower is 30√3 meters.

The bridge is said to be balanced when deflection in galvanometer is zero(I_g=0), i.e., no current flows through the galvanometer(branch BD).In the balanced condition,
P/Q=R/S
On mutually changing the position of the cell and galvanometer, this condition will not change.
 

A body at temperature T produces a continuous spectrum of wavelengths. For a black body, the wavelength corresponding to maximum intensity of radiation is given according to Planck's law by the relation, m=0.29cmK/T. For m=106m,T=2900K.Temperatures for other wavelengths can be found. These numbers tell us the temperature ranges required for obtaining radiations in different parts of the electromagnetic spectrum. Thus, to obtain visible radiation, say  =5×107m, the source should have a temperature of about 6000K. A lower temperature will also produce this wavelength but not the maximum intensity.

No. of atoms in 1 mole of PCI₃ = 4
No. of atoms in 1.4 moles of PCI₃
= 4 x 1.4 x 6.022 x 10²³ = 3.372 x 10²⁴

Chemistry does not deal in explaining superconductivity.

Electronegativity is measured on Pauling scale. Fluorine, the most electronegative element is given the value 4.0. Electronegativity increases from left to right across a period while decreases down a group.

Exotic cattle were first introduced into this region by colonial farmers. Thus, the origin of exotic cattle is generally traced back to Europe. The most common exotic dairy breeds in the region are Friesian, Holstein, Ayrshire, Jersey, Guernsey and Sahiwal. However, the Friesian breed predominates.

The peripheral nervous system facilitates communication between the central nervous system and other parts of the body.

Leghorn is probably the best egg-laying breed to introduce to tropical Countries, if conditions are not too harsh. Eggs are produced at a lower price and the large comb and wattles, naked legs and white feathers are all factors favouring thermo-tolerance. Where a hot climate and insufficient feeding are limiting factors, Leghorn-derived breeds are more suitable and may also be utilised to improve  the genetic pool of local strains.

Long distance radio broadcasts use shortwave bands because only these bands can be refracted by the ionosphere.
