Mathematics QUESTION #1313

For the IVP \(y'=1+y/x\), \(y(1)=2\), \(h=0.25\), Euler's first step gives \(y(1.25)\approx\):

\(2.75\)✔️
\(3.00\)
\(2.50\)
\(3.25\)

Correct Answer Logic:

\(f(1,2)=1+\dfrac{2}{1}=3\). \(y_1=y_0+h\cdot f(x_0,y_0)=2+0.25\times3=2+0.75=2.75\).

Mechanical Engineering QUESTION #2480

The inertia force \(\mathbf{F}_{in}\) introduced in D'Alembert's principle for a rigid body with center of mass acceleration \(\mathbf{a}_C\) and mass \(m\) is:

\(\mathbf{F}_{in} = m\mathbf{a}_C\)
\(\mathbf{F}_{in} = -I_C\boldsymbol{\alpha}\)
\(\mathbf{F}_{in} = -m\mathbf{a}_C\)✔️
\(\mathbf{F}_{in} = m\mathbf{g}\)

Correct Answer Logic:

D'Alembert's principle introduces the inertia force \(\mathbf{F}_{in}=-m\mathbf{a}_C\) and inertia moment \(M_{in}=-I_C\alpha\). Adding these fictitious terms to real external forces converts the dynamic problem into an equivalent static equilibrium.

Income Statement
Statement of Financial Position
Statement of Cash Flows
Statement of Owner's Equity✔️

Correct Answer Logic:

The Statement of Owner's Equity (also called the Capital Statement) shows changes in the owner's capital account during the period.

Mathematics QUESTION #1276

The order of the cyclic subgroup generated by \(\bar{6}\) in \(\mathbb{Z}_{18}\) is:

2
3✔️
6
9

Correct Answer Logic:

The order of \(\bar{a}\) in \(\mathbb{Z}_n\) is \(\dfrac{n}{\gcd(n,a)}\). Here \(n=18\), \(a=6\): order \(=\dfrac{18}{\gcd(18,6)}=\dfrac{18}{6}=3\).

Chemistry QUESTION #1020

Arrange \(\text{HBr}\), \(\text{H}_2\text{S}\), \(\text{NF}_3\) and \(\text{CHCl}_3\) in increasing order of their dipole moment:

\(\text{H}_2\text{S} < \text{HBr} < \text{NF}_3 < \text{CHCl}_3\)
\(\text{NF}_3 < \text{HBr} < \text{H}_2\text{S} < \text{CHCl}_3\)✔️
\(\text{HBr} < \text{H}_2\text{S} < \text{NF}_3 < \text{CHCl}_3\)
\(\text{CHCl}_3 < \text{NF}_3 < \text{HBr} < \text{H}_2\text{S}\)

Correct Answer Logic:

Dipole moments (approx): \(\text{NF}_3\approx0.24\ \text{D}\) (F pulls away from N lone pair, net dipole is small); \(\text{HBr}\approx0.82\ \text{D}\); \(\text{H}_2\text{S}\approx0.97\ \text{D}\); \(\text{CHCl}_3\approx1.87\ \text{D}\). Increasing order: \(\text{NF}_3 < \text{HBr} < \text{H}_2\text{S} < \text{CHCl}_3\).

Physics and Math QUESTION #757

A small parallel resistance (shunt) used to convert a galvanometer into an ammeter is given by:

Rs = (Ig/(I-Ig)) x Rg✔️
Rs = (Ig-I)/Ig
Rs = Ig/(I-Iθ)
None

Correct Answer Logic:

The shunt resistance Rs = IgRg/(I-Ig). This ensures most current bypasses the galvanometer making it function as an ammeter.
