The electrical voltage in a certain region of space is given by the function V(x,y,z)=80+xz−sin⁡(yz). If the directional derivative of V at (1,1,π) in the direction 〈a,−1,π〉 is π, what is the value of a?

Group of answer choices

π22

−π22

π2

−π2

None of the above.

What is the standard voltage or cell potential of a Cr-Hg cell? (Remember to switch one-half reaction to oxidation and to balance the number of electrons--use paper.)

Cr³⁺(aq)+ 3e^- → Cr(s) E^o = -0.74 V
Hg²⁺(aq)+ 2e^- → Hg(l) E^o = +0.789 V

1. A voltage is given by v(t) = 10 sin(1000?t + 30o).

a. Use a cosine function to express v(t).

b. Find the angular frequency, the frequency in hertz, the phase angle, the periodic time and the rms value.

c. Find the power that this voltage delivers to a 25? resistance

When an AC source is connected across a 11.5-? resistor, the rms current in the resistor is 8.66 A.

(a) Find the rms voltage across the resistor.
V

(b) Find the peak voltage of the source.
V

(c) Find the maximum current in the resistor.
A

(d) Find the average power delivered to the resistor.
W

(a) Using Kirchhoff’s laws, derive an equation for the voltages, V1 and V2, across two resistors, R1 and R2, in series connected to a voltage supply V .

(b) Using Kirchhoff’s laws, derive an equation for the voltages across two resistors R1 and R2 in parallel connected to a voltage supply V .

You have researched Muller v. Oregon and have read Supreme Court Declares School Segregation Unconstitutional in Brown v. Board of Education. Choose one of these cases and look at the impact it had on society at the time. Look through the rulings and see what the justices on each side argued.

Program 1-100 integer accumulation using RISC-V assembly.

Note: RARS only simulates 320-bit instructions of RISC-V, so make sure you use the instruction that operate work-size data type (mostly with `w` as the last character of the instruction mnemonic)

Golf has returned to the Olympic Games. In its first games back in the 2016 Rio games, many of the biggest name PGA Tour players did not compete or participate in the Olympics. What are some options that golf officials could pursue in order to make the Olympic Games more attractive to draw the biggest names in golf?

When considering this the scenario and question, develop a plan to encourage golfers to pursue a medal at the Olympic Games. Answer the following questions as part of developing your plan. This case study will require additional individual research concerning Olympic golf.

1. Why were golfer's not interested in the Olympic Games? Was it location, prestige, timing, etc.

2. Considering the answers (issues) to question 1, what are two strategies to resolve those issues?

3. What type of policy could be implemented that encourages, punishes, and/or rewards golfers that pursue the Olympics? How would the PGA implement and govern such a policy?

4. How and why would this policy be effective?
