Which of the following statement is not true considering a cubic lattice system? are not perpendicular to each other b) Direction is parallel to plane (hkl), when uh+vk+wl=0 c) Direction is perpendicular to the plane (hkl) when u=h, v=k, w=l d) Two planes (hkl) and (abc) are perpendicular to each other if h=a, k=b, l=c Correct Answer The crystallographic plane (uvw) and crystallographic direction are not perpendicular to each other

Only for cubic lattice the crystallographic plane (uvw) and crystallographic direction are perpendicular to each other. Two planes (hkl) and (abc) are perpendicular to each other if: => ha+kb+lc=0.

Road damage is often down to a few factors such as the quantity of traffic, the weight of the vehicles passing on it, and environmental conditions. XYZ town has a port, called ABC. To get to ABC, there is a road, that is divided into two lanes. One for the traffic going towards ABC port, and the other for traffic going away from ABC port. The lane of the road that leads to ABC port, has significantly less damage, than the lane that leads away from it. Which of the following helps explain this best?
A cubic material is made by melting three smaller cubic materials of sides 6, 8, and 10 cm. The total surface area of new cubic material so formed is what percent of the total surface areas of all small cubic materials?
A large plane, perfectly insulated on one face and maintained at a fixed temperature T 1 on the bare face, has an emissivity of 0.84 and loses 250 W/m2 when exposed to surroundings at nearly 0 K. The radiant heat loss from another plane of the same size is 125 W/m2 when bare face having emissivity 0.42 and is maintained at temperature T 2 is exposed to the same surroundings. Subsequently these two planes are brought together so that the parallel bare faces lie only 1 cm apart and the heat supply to each is so regulated that their respective temperatures T 1 and T 2 remains unchanged. Determine he net heat flux between the planes

There is a hint in this question and a statement is given later. Carefully read the excerpts provided and determine the statement based on that episode. The current Australian team has lost three of their last five Test series. They lost their last two Test series, one of which was against Pakistan, which is not considered to be a strong team now. Australia's two best batsman, Steve Smith and David Warner are currently suspended and their absence has weakened the Australian team. There is a lot of dissatisfaction and introspection about how their national team plays in Australia, how they show aggression on the field, how they do not show respect to the team against them, and neglecting the media at the most, and focusing only on winning only, the discussion on the future of the game is ongoing. There are. Australian cricket never reached such a low level. This is the best opportunity to knock them into their own house. In other words, if this India could not beat Australia in Australia in this series, then it would prove that the campaign around this team is only the same: the propaganda. Statement: India has a good chance of defeating Australia. Choose the right one from the next option A - The statement is completely true. B - statement is most true. There is no definitive definition based on C-statement. D-statement is completely false.
