A satellite orbiting the Earth at 400 km above the surface of the Earth has a 2 m long antenna oriented perpendicular to the Earth's surface. At the equator the Earth's magnetic field is 8×10−5 T and is horizontal. Assuming the orbit to the circular, find emf induced across the ends of the antenna.(Given radius of earth Re =6400 Km)
A sled is pulled from rest by a net force of 2.8 N [forward]. The sled moves 7.4 m, reaching a velocity of 3.9 m/s [forward]. Determine the mass of the sled.
A given mass of nitrogen is 0.12 dm³ at 60⁰C and 1.01×10⁵ Nm–². Find it's pressure at the same temperature if it's volume is changed to 0.24 dm³.
Common Entrance are usually graded out of 150 marks. The education officers of one of the education districts, knows that the mean score in the district is 80 with a standard deviation of 20. The students’ scores follow a normal distribution. There are 500 students in the district who sat the Common Entrance Exam.
3) The education officer has promised to provide scholarships to the students in the district whose performance are in the top 1%.
i) What score separates the top 1% of students from the bottom 99% ?
ii)How many students are eligible to receive the scholarship?
If P(B) = 0.15, P(A | B) = 0.50, P(B′) = 0.85, and P(A | B′) = 0.60, find P(B | A)
Nitrogen gas and hydrogen gas are combined in a reaction to produce ammonia. If 6.0 moles of N2 and 6.0 moles of H2 are present in the mixture, which is the limiting reactant?
PLEASE SHOW WORK! THANKS!
Charges are equal and opposite on two parallel plates. When space was evacuated, the electric field was 2.80 x 105 V/m. When it was filled with a dielectric material, the electric field was 1.20x105 V/m. What is the dielectric constant? What is the material?
