What power must be in place when you first place a slide on the microscope stage? When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next […]

What must be added to the polynomial f/x )= x 4 2×3 − 2×2 X − 1 so that the resulting polynomial is exactly divisible by x2 2x − 3 )? Hence, (x−2) must be added to the polynomial x4+2×3−2×2+x−1 so that the resulting polynomial is exactly divisible by x2+2x−3. What must be added to […]

How do you calculate V peak to peak? Alternating Current (AC) the peak to peak voltage = 6 squares from the highest point to the lowest and each square is worth 10V. So the peak to peak voltage = 60 V. the peak voltage ( Vo )= half the peak to peak voltage = 60 […]

What effect does the wind chill factor have on temperature? The wind chill factor describes what happens to a body when it is cold and windy outside. As wind increases, heat is carried away from the body at a faster rate, driving down both skin temperature (which can cause frostbite) and eventually the internal body […]

How do you prevent hydroplaning? How do I Avoid Hydroplaning? Keep your tires properly inflated. Rotate and replace tires when necessary. Slow down when roads are wet: the faster you drive, the harder it is for your tires to scatter the water. Stay away from puddles and standing water. Avoid driving in outer lanes where […]

What is the most common method of welding? Shielded Metal Arc Welding What are the techniques of welding? The following are the commonly used welding methods: Stick/Arc welding (SMAW) Metal Inert Gas (MIG) welding or GMAW. Tungsten Inert Gas (TIG) welding or GTAW. Flux-Cored Arc Welding. What are the common welding techniques used to different […]

How do you calculate heat loss through a wall? Heat loss from the walls: Area of the walls = 1,920 ft2, HDD = 6,100, and the composite R- value of the wall needs to be calculated. Total heat loss from the house = 13.78 + 84.91 + 18.30 =116.99 MMBTU in a year or heating […]

What is the resolution of 8-bit ADC? An ADC generates a digital output that’s proportional to the ratio of the input voltage to the input range. The resolution (Δ or least significant bit) is this range divided by the total number of possible steps. For example, an 8-bit ADC with a 2.048-V input range has […]

How do you calculate gearbox torque? The torque is calculated as follows: Obtain load F of the meshing point (at the radius of the pitch circle of Gear A) of the input torque. Obtain torque of the output side from load F of the teeth’s meshing point (radius of the pitch circle of Gear B). […]

What do you call the machine that cuts off heads? A guillotine (/ˈɡɪlətiːn/ GHIL-ə-teen, also US: /ˈɡiːətiːn/ GHEE-, French: [ɡijɔtin] ( listen)) is an apparatus designed for efficiently carrying out executions by beheading. The device consists of a tall, upright frame with a weighted and angled blade suspended at the top. What is a guillotine […]
