This is about method of taking inside measurement with a tape.
<u><em>Option A is the correct answer.</em></u>
- Inside measurement is usually taken with the aid of an inside micrometer. This will give us an exact measurement. This is because when making use of an inside micrometer for inside measurement, the total length of the inside micrometer is equal to the overall length of whatever is being measured.
- We have seen how the inside micrometer is used whereby the entire body is also included in whatever is being measured. Applying this same concept to using a tape, we can simply say that we will add the tape length to the measuring case to get the inside measurement.
- From the definitions and comparisons above, we can see that we will have to add the length of the tape measure case when taking inside measurements and other options aside Option A are not correct.

The time constant to reach full charge in an RL circuit is 0.05 ms.
Explanation:
To find the time constant,
The time constant for an RL circuit is defined by τ = L/R.
The given data is
L= 5 H
R= 100 ohms
by using the formula,
τ = L/R
= 5/100
= 0.05 ms
τ = 0.05 ms
Thus, the time constant to reach full charge in an RL circuit is 0.05 ms.

False......................
Answer:
Plane shell which is option b
Explanation:
The temperature in the case of a steady one-dimensional heat conduction through a plane wall is always a linear function of the thickness. for steady state dT/dt = 0
in such case, the temperature gradient dT/dx, the thermal conductivity are all linear function of x.
For a plane wall, the inner temperature is always less than the outside temperature.
Strangely enough, the most complex building to design is the common house. I know, they’re like belly buttons, even if you don’t have one yourself, you know someone that has one, and you’ve certainly been in one.
A house has all the ingredients that you will find in far more complex buildings. On top of that, they are there in small quantities.
Nearly every house has a kitchen, bathroom, laundry and toilet. You will also find some of these in hospitals, hotels, parking stations, office blocks, sewerage works, defence facilities and so on.
The only difference is that in a house, there may only be one of these and it must be the right size, shape and position so that it is suitable for use. Even the doorways must be positioned correctly - to allow for ventilation, light, privacy , ease of access, safety and even feng-shui.
Each room must be the right size for its’ occupants and its’ usage. Bedrooms should have a window or some other method of providing natural light. Toilets and bathrooms should allow for privacy.
The materials that it is built of should be fit for purpose. The roof should provide shelter from the elements. The walls should be able to support the weight of the roof and provide shelter and security for the occupants. The floor should be stable and strong and able to support the activities that are carried out in the house.
On top of all that, it must look good - to somebody. It also must be comfortable to live in, otherwise the design is a fail. That doesn’t mean that it shouldn’t be cheap to build. A good designer designs with one eye on the asthetics, the other eye on the usage and utility and his hand firmly closed around the cheque-book.
