Mention the common radii and definition angle for standard circular curves​

Answer»

A CIRCULAR CURVE is a segment of a circle — an arc. The sharpness of the curve is determined by the radius of the circle (R) and can be described in TERMS of “degree of curvature” (D). ... Degree of curvature is not used when WORKING in metric units.Hope it helps you ❤️

3)Define the terms. a) Dimensionsb)Absolute errorc)Dimensional formulad)Relative error​

Answer» TION:a measurable extent of a particular kind, such as length, breadth, depth, or height.ABSOLUTE Error is the amount of error in your measurements. It is the difference between the MEASURED value and “true” value. For EXAMPLE, if a scale states 90 pounds but you know your true weight is 89 pounds, then the scale has an absolute error of 90 lbs – 89 lbs = 1 lbForce (F) [F] = [M L T-2]Power (P) [P] = [M L2 T-3]Velocity (v) [v] = [M L T-1]DENSITY (D) [D] = [M L3 T0]Relative error (RE)—when used as a measure of precision—is the ratio of the absolute error of a measurement to the measurement being taken. In other words, this type of error is relative to the size of the item being measured. RE is expressed as a percentage and has no units.

Uses of equatorial satellites​

Answer»

lite in equatorial orbit flies ALONG the line of the Earth's equator. To GET into equatorial orbit, a satellite must be launched from a place on Earth close to the equator. NASA often launches satellites aboard an Ariane rocket into equatorial orbit from French Guyana.Equatorial orbitEquatorial ORBITS can be USEFUL for satellites observing tropical weather patterns, as they can monitor cloud conditions around the globe.Equatorial orbits are usually MEDIUM or low orbits.hope it's helpful to you....

Define error, state basic types of error and explain each in brief.​

Answer»

The measurement error is defined as the difference between the true or actual value and the measured value. The true value is the average of the infinite number of measurements, and the measured value is the precise value. The error may arise from the different source and are usually classified into the following types. These types are Gross Errors Systematic Errors Random Errors Gross Errors The gross error OCCURS because of the human mistakes. For examples consider the person using the instruments takes the wrong reading, or they can record the incorrect data. Such type of error comes under the gross error. The gross error can only be avoided by taking the reading carefully. Systematic Errors The systematic errors are MAINLY classified into three categories. INSTRUMENTAL Errors Environmental Errors Observational Errors Random errors:- the error which is CAUSED by the sudden change in the atmospheric condition, such type of error is called random error. these type of error remain even after the removal of the systematic error. hence such type of error is called as random errors. Minimising errors: These errors can be minimised by using proper instruments, improving the experimental procedure and removing personal bias. Explanation:

10 g of water at 80℃ is mixed with 50g of copper at 10℃. Find the final temperature​

Answer»

Explanation:since it is given that 50 gm water at 20 ⁰ C and 50 gm of water at 40⁰ C are mixed.  Since the masses of the liquid at different TEMPERATURES are same, the answer is very easy and simple :  average of 20⁰C and 40⁰C.  that is:  30⁰C.final temperature of the mixture = [ m 1 * T 1 + m 2 * T 2 ] / (m 1 + m 2)= [ 50 gms * 20⁰ C + 50 gms * 40⁰C ]  / (50+50) = 3,000 / 100 = 30⁰C another way using specific heats : LET the final temperature be = T ⁰C  AMOUNT of heat given out by the hot water = m * s * (40⁰C - T)           = 50 gms * s* (40 -T)   Amount of heat taken in by the cold water = m * s * (T - 20⁰C)       = 50 gms * s * (T - 20 )   As the amounts are equal, because the heat is transferred from hotwater to the cold water without any loss of heat to any surroundings,           50 * s * (40 -T) = 50 gm * s  * (T-20)                   40 - T = T - 20             2 T = 60    => T = 30⁰C
