Answer:
Horizontal force = 89.2 N
Explanation:
The frictional force = coefficient of friction * magnitude of the force (weight of the body) * cos theta
Substituting the given values, we get -
Frictional Force = 0.3*300 * cos 25 = 89.2 N
Horizontal force = 89.2 N
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.
Answer:
C. The vehicle safety check indicates the ABS is functioning normally.
Explanation:
ABS, an antilock braking system, is a safe and secure slip-resistant braking system in cars and air-crafts. <u>An ABS is there to prevent wheel-locking while using brakes in vehicles</u>.
When one ignites a car, the ABS indicator will light up briefly as a part of safety check.<em> The ABS indicator light comes on for a few seconds before it turns off again. This indicates that the ABS system is functioning normally</em>. But, if the ABS indicator light remains after turning on the ignition, this indicates that there is a problem in the system.
In the given scenario, the ABS indicator is functioning properly, thus the correct answer is the third option (C).
Ada Lovelace Day, celebrating Ada, Countess of Lovelace as the first computer programmer, is traditionally celebrated on the second Tuesday of October each year is given below
Explanation:
1.The second Tuesday of every October marks Ada Lovelace Day, a day founded in 2009 by technologist Suw Charman-Anderson, to celebrate the achievements of women in Stem careers (science, technology, engineering and mathematics), and was created in memory of one in particular: Ada Lovelace, the first computer programmer.
2.Ada Lovelace: The First Computer Programmer. Ada Lovelace has been called the world's first computer programmer. ... By 1834 he had moved on to design his Analytical Engine, the first general purpose computer, which used punch cards for input and output. This machine also lacked financing and was never built.
3.Born two centuries ago, Ada Lovelace was a pioneer of computing science. She took part in writing the first published program and was a computing visionary, recognizing for the first time that computers could do much more than just calculations.
4.Through Babbage, Ada began studying advanced mathematics with University of London professor Augustus de Morgan. Ada was fascinated by Babbage's ideas. Known as the father of the computer, he invented the difference engine, which was meant to perform mathematical calculations.
5.It's Ada Lovelace Day today which means it is a time to celebrate the achievements of women working in the fields of science, technology, engineering and mathematics (STEM). Now in its eighth year, the annual celebration was founded by journalist and software activist Suw Charman-Anderson.
