The size of moon keeps changing when viewed from earth. This change is called phases of moon. The part of moon on which sunlight falls is visible to us.

Relation between kinetic energy and frequency is K.E+ϕ=hν.
Here h is planck's constant, ϕ=constant (Work function)
According to the above equation of photoelectric effect, as we increase frequency of photon, kinetic energy of photoelectron increases. Because the frequency of incident light is directly proportional to kinetic energy.
Hence option C is correct.
 

Explanation:

from work–energy theorem

change in kinetic energy = work done

ΔK = W

K_f - K_i = Fs

1/2mv² - 0 = Fs

m = 4.30 kg, s = 1.2m, F = 36N

v_f = vm/s , v_i = 0

We know that gravitational acceleration, g = GM/R²
We know that M = Mass of earth /1700 and R = Radius of earth /8
Hence we get g = 64/1700 times the gravitational acceleration of earth
I.e. g = 64/1700 x 9.8 
= 0.37 m/s²

Given Data:

• The average of 8 numbers is 25:
  • Sum of all 8 numbers = 8 × 25 = 200
• The average of the first two numbers is 20:
  • Sum of the first two numbers = 2 × 20 = 40
• The average of the next three numbers is 26:
  • Sum of the next three numbers = 3 × 26 = 78
• The sixth number (x) is:
  • 4 less than the seventh (y): y = x + 4
  • 6 less than the eighth (z): z = x + 6

Step-by-Step Solution:

Step 1: Sum of the last three numbers

From the total sum:

Sum of the last three numbers = 200 - (Sum of the first five numbers)

Sum of the last three numbers = 200 - (40 + 78) = 200 - 118 = 82

Step 2: Equation for the last three numbers

The last three numbers are x, y, and z. Using their relationships:

x + y + z = 82

Substitute y = x + 4 and z = x + 6 into the equation:

x + (x + 4) + (x + 6) = 82

3x + 10 = 82

3x = 72 ⇒ x = 24

Step 3: Find y and z

Using x = 24:

• y = x + 4 = 24 + 4 = 28
• z = x + 6 = 24 + 6 = 30

Verification:

The sum of the last three numbers is: 24 + 28 + 30 = 82

This matches the required sum, confirming our calculations.

Final Answer:

The last number is 30.

Raju being twice as good a workman as Vijay, you can solve the following equation to get the
required answer:
1/R + 1/2R = 1/14.
Solving will give you that Vijay takes 42 days.

16 * 1.5 = 24

444 ÷ 24 = 18.5

So Option C is correct

x² = 529 * 324 ⇒ x = 23 * 18 = 414

So Option B is correct

LCM of 12, 15, 25 and 30 is 300
least number of 4-digit divided by 300 is 1200

12% percent didn’t cast their vote. 45% of total votes get by the winning candidates, so remaining 43% will be scored by his rival. So, (45/100 -43/100)*P = 2000
P = 100000

Carbon forms bonds with other atoms by sharing electrons because it requires a lot of energy to remove four electrons. Adding four electrons to carbon de-stabalises it. Therefore, it completes its octet by sharing electrons.

Let the amounts of water in the bottles be V, 2V, 3V, 4V, 5V and 6V.
So, total water poured = 21V
Let the capacity of each bottle be C.
So, capacity of six bottles = 6C
Capacity of jar = 3C
As the jar is completely filled, we have
21V = 3C
Or 7V = C
Now, 70% of 7V = 4.9V
Thus, there are two bottles which were at least 70% filled with water.
Hence, answer option 3 is correct.

100 litres of mixture has 80 litres of milk and 20 litres of water.
When 25 litres of mixture is taken out, it contains 20 litres of milk and 5 litres of water.
So, milk left = 60 litres and water left = 15 litres.
If 25 litres of water is added, then ratio of water to milk = 40 : 60 = 2 : 3

 Height of the cylinders = 42 cm
Radius of the outer cylinder = r₁ = 16/2 = 8 cm
Radius of the inner cylinder = r₂ = 14/2 = 7 cm
Therefore, volume of the cork dust required = Volume of the outer cylinder – Volume of the inner cylinder

= 1980 cm³

Average rate of tap = 2/3 drops/sec
Total number of drops in the completely filled vessel = 2080
So, time taken by the tap to drip 2080 drops 
i.e. Time required to fill the vessel = 3120 sec
∴ Number of times that the vessel be filled in this manner in 13 hours
