A closed coil of 40 turns and of area 200 cm2, is rotated in a magnetic field of flux density 2 Wb m-2. it rotates from a position where its plane makes an angle of 30° with the field to a position perpendicular to the field in atime 0.2 sec. Find the magnitude of the emf induced in the coil due to its rotation.
Combustion of an 8.23 mg sample of a compound
gave 9.62 mg of carbon dioxide and 3.94 mg of water.
Analysis of another 5.32 mg sample of the same
compound by the Carius method gave 13.49% mg of
AgCl. Calculate the % composition and empirical
formula.
1:The average amount of miles a car battery lasts for in a 2019 sedan is 37,452 miles with a standard deviation of
4,890 miles. If this distribution is normally distributed, answer the following questions:
A: What is the probability you select a battery it last longer than 40,000 miles?
B: What is the probability you select a battery, and it lasts between 32,000 miles and 44,000 miles?
C: Where does the top 18% of longest lasting batteries begin (at what mileage)?
Name one of the key differences between environmental science and natural science.
An electron is accelerated from rest through a potential difference is 15V.What is the change in electric potential energy of the electron?
Test whether the series ∞Σn=0 1/(n^5+x^3) converges uniformly or not
An electrical firm manufactures light bulbs that have a length of life that is approximately normally distributed, with mean equal to 813 hours and a standard deviation of 65 hours. Find the probability that a random samples of 34 bulbs will have an average life of greater than 803 hours.
Industrially, vanadium metal ,which is used in steel alloys,can be obtained by reacting vanadium oxide with calcium at high temperatures:
In one process,1.54×10^3g of V2O5 react with 1.96×10^3g of Ca.
Calculate the theoretical yield of V....
Describe a procedure for making rock candy using sucrose. At 20°C, the solubility of sucrose is 230.9 g/100 g H2O. At 50°C, it is 260.4 g/100 g H2O. At 100°C, it is 487 g/100 g H2O
An 8.00 mg sample of an organic compound was
subjected to quantitative combustion to give 15.33 mg
of carbon dioxide and 9.36 mg of water. The
molecular weight was found to be 46. Calculate the %
