Calculate the hall effect of sodium based on free electron model.sodium has bcc structure and side of the cube is 4.28A
1. Ruel is on his way to the grocery store riding his motorcycle. He started at rest in front of their house. He then travels ahead so that his distance from where he started is given by the equation: x(t) = (2.4 m/s2) t2-(0.120 m/ s2) t3
a. Calculate the average velocity of the motorcycle for the time interval t=0 sec to t=10 sec.
b. Determine the instantaneous velocity at t=0 sec and t=5 sec
A particle moves on a line with a constant acceleration of 4ft/second. Find its equation of motion if s=2ft and v=-ft/sec, when t=2sec
A box has a mass of 5.8 kg. The box is lifted from the garage floor and placed on a
shelf. If the box gains 245 J of potential energy, how high is the shelf?
Compare the mechanisms for the following substitution and addition reactions of benzene:
o the Friedel-Crafts reaction
o the sulfonation of benzene
o the chlorination of benzene
o the hydrogenation benzene
You will need to illustrate and explain the reaction mechanism for each one, as well as the similarities and differences that exist between them.
Could you list some similarities and differences for each mechanisms please?
1) New cars are normal good and people’s incomes increase. Simultaneously, auto manufacturers must pay more for their worker’s health insurance. What is the effect on price and quantity of new cars?
2) The table below gives a supply schedule.
Point | Price (RM) | Quantity Supplied
A 5 10
B 15 30
C 25 50
D 35 90
a. Using the midpoint method, calculate the price elasticity of supply between points A and B; between B and C and between C and D.
b. Why is the elacticity of supply always positive?
c. Why does the elasticity of supply increase in value as more time passers after a price hike?
