1 ohm is the resistance of a conductor such that when a potential difference of 1 volt is applied to its ends, a current of 1ampere flows through it.
A megavolt (symbolized MV) is equal to one million volts (1 MV = 106 V).

Haustoria.
Hustoria is the appendage or portion of a parasitic fungus or of the root of a parasitic plant that penetrates the host's tissue and draws nutrients from it. Haustoria do not penetrate the host's cell membranes. It is a parasitic vine which climbs other plants and takes nutrition directly from them via a haustorium.

Charge given, Q = 96000 C
Time given (t) = 1 hour =60 × 60 s = 3600 s
2 hour = 2 (3600) = 7200
Voltage (V) = 40 V
We know that, current can be found out by using the formula,
{tex}\begin{array} { c } { I = \frac { Q } { t } } \\\\ { I = \frac { 96000 } { 7200 } = \frac { 80 } { 6 }= \frac { 40 } { 3 } A } \end{array}{/tex}
Amount of heat generated can be found out using the formula,
{tex}\begin{array} { c } { \mathbf { H } = \mathbf { V I t } } \\\\ { = 40 \times \frac { 40 } { 3 } \times 7200 } \\\\ { = 384000 \mathrm { J } } \\\\ { = 3.84 \times 10 ^ { 6 } \mathrm { J } } \end{array}{/tex}
Thus, the “amount of heat” generated is {tex}3.84\times10^6 J{/tex}
