Car A is moving at a speed of 45km/h towards car B which is moving at a speed of 55km/h. if the two car were initially separated at a distance of 150km, determine how long it will take the two cars to meet?​

is it likely that Rapid Lube has increased productivity over its more traditional competitors? Why? How would we measure productivity in this industry? your lead developer is including input validation to a web site application. which one should be implemented:A. pointer dereferencingB. boundary checksC. client side validationD. server side validation Give a big-O estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment of an algorithm. t=0 for i:=1 to 3 for j :=1 to 4 1 :=1 tij A O(1) B. O(n) C. O(n log n) D. On) I In Solow's model of economic growth, suppose that s represents the savings rate, z represents total factor productivity, k represents the level of capital per worker, and f(k) represents the per-worker production function. Also suppose that n represents the population growth rate and d represents the depreciation rate of capital. The equilibrium level of capital per worker, k, will satisfy the equationA) f(k*) = s/(n + d) k*.B) nf(k* ) = s/k (s + d) . C) szf(k*) = ( n + d)k*. D) szk = (n + d)f(k*). Use the information and table to answer the following question A student is planning to determine the specific heat of iron. To do this experiment the student will need to perform the following procedures: StepProcedure 1 Measure the mass of the iron sample 2 Measure the initial temperature of a known volume of water 3 Heat the iron sample . 4 Place the iron sample in the water What is Step 5 in the experiment? Identify the correct presumptive findings for each streptococcal group. Streptococcus pneumoniae Streptococcus agalactiae Group C Streptococci Group D EnterococciViridans StreptococciStreptococcus pyogenes Positive salt-tolerance and bile esculin testsPositive CAMP reaction Alpha- or nonhemolytic; negative on bile esculin, salt-tolerance, and optochin tests Positive optochin sensitivity Beta-hemolytic; resistant to bacitracin; negative CAMP test Beta-hemolytic and senstitive to bacitracin evaluate exactly, using the fundamental theorem of calculus: b0 (x^6/3 6x)dx The most general sinusoidal velocity profile for laminar boundary layer flow on a flat plate is u = A sin (By) + C. State three boundary conditions applicable to the laminar boundary layer velocity profile and evaluate the constants A, B, and C. what is an example to illustrate the first postulate of special relativity a) let f = 5y i 2 j k and c be the line from (3, 2, -2) to (6, 1, 7). find f dr c = ____ fill in the code for the cout statement that will output (with description) // the area What change in volume results if 170. 0 mL of gas is cooled from 30. 0 C to 20. 0 C?

Lots of things require balance: riding a bike, walking a balance beam, jumping rope. Losing balance can cause us to get hurt. The same is true for living things. Plants and animals must maintain an internal balance to stay healthy. Living things have internal communication systems that help to keep things in homeostasis or balance. A stimulus is any change in an organisms environment that causes the organism to react. The change can be internal or external. For example, when you get hot, you move to the shade. The heat is an external stimulus and moving to the response is the response you make to cool off or come back to homeostasis. If you get hungry, you eat a snack. The hunger is an internal stimulus. Eating a snack is your response.Which of these is a response to an external stimuli? Select ALL that apply.A.) hibernationB.) phototropismC.) wiltingD.) thirstE.) dormancy A radio-controlled model airplane has a momentum given by [(0.75kgm/s3)t2+(3.0kgm/s)]i^+(0.25kgm/s2)tj^ , where t is in seconds.Part AWhat is the x -component of the net force on the airplane?Express your answer in terms of the given quantities.Fx(t) =__Part BWhat is the y -component of the net force on the airplane?Express your answer in terms of the given quantities.Fy(t) =__Part CWhat is the z -component of the net force on the airplane?Express your answer in terms of the given quantities.Fz(t) =__ Experiment 1: Charles' Law Data Tables and Post-Lab Assessment Table 3: Temperature vs. Volume of Gas Data Temperature Temperature (C)Volume (mL) Conditions Room Temperature Hot Water Ice Water 21 1.2 48 2.2 10 0.8 1. A typical tire pressure is 45 pounds per square inch (psi). Convert the units of pressure from psi to kilopascals. Hint: 1 psi 6900 pascal 2. Would it be possible to cool a real gas down to zero volume? Why or why not? What deo you think would happen before that volume was reached? Is your measurement of absolute zero close to the actual value (-273 C)? Calculate a percenterror. How might you change the experiment to get closer to the actual value?
