Potentiometer is prefered over a voltmeter because: 1. Potentiometer give the exact value of potential difference across any two points in a circuit because it never draws any current from the circuit. But Voltmeter draws apart of the current so there is an error in measurement of the potential diffRead more
Given, Height of water tank (h)=2m Hence, the water if half filled the height will be 1m. We know that, Density of water (d) = 1000kg/m^3 Acceleration due to gravity (g) = 9.8m/s^2 Now, by using the formula to find the pressure P = dgh = 1000×9.8×1 =9800 pascal Hence, the pressure exerted is 9800 paRead more
The lifetime of a star depends on two things; how much fuel it has and how fast it uses it up. We know that hydrogen is the main fuel source and that most of a stars mass consists of hydrogen. This means that the amount of fuel is proportional to the total mass of the star. The most massive stars haRead more

नोभल कोरोना भाइरस (CoV) कोरोना भाइरसकै एक नयाँ प्रजाति हो। यसलाई हाल कोरोनाभाइरस रोग २०१९ (अर्थात कोभिड-१९) नामाकरण गरिएको छ जसमा ‘को’ ले कोरोना र ‘भि’ ले भाईरस भन्ने जनाउँछ। यस भन्दा पहिले यो रोगलाई ‘२०१९ नोभल कोरोना भाइरस’ वा ‘२०१९-एन-कोभि (2019-nCoV)’ भन्ने गरिएको थियो। कोभिड-१९ भाइरस एक परिवर्तिRead more

I think the key difference between them is. Sundry Debtors = 1.They are the parties who owed a sum of money towards the entity. 2. They are account receivable form 3. They comes under asset category. Examples = Loan to Mr.X Sundry Creditors = 1.They are the parties to whom a company owes an obligatiRead more
If any number divided by 5 leaves a remainder of 3; then the number must have either 3 or 8 in its unit’s place. Now, any number ending with 8 can’t leave a remainder of 3 when divided by 6 or 8. So, the number must end with 3. Now, LCM(5, 6, 7, 8) = 840. Therefore, this number (say, x) - 3 = 840*zRead more
In a group of 6 boys and 4 girls, four children are to be selected such that at least one boy should be there. Hence we have 4 options as given below We can select 4 boys ...(option 1) Number of ways to this = 6C4 We can select 3 boys and 1 girl ...(option 2) Number of ways to this = 6C3 × 4C1 We caRead more
Explanation: given, mass of body(m)=m maximum height (h2)= 2meters minimum height (h1)= 0.75meters gravitational force(g)=10meter per second velocity (V)=? We know that, potential energy = kinetic energy potential energy (P.E) = mgh2 - mgh1 kinetic energy (K.E)= 1/2mv2 1/2mv2= mgh2-mgh1 1/2mv2=mg(h2Read more
