Basically, the purposes of digital multimeter are to measure two or more electrical values such as:
principally voltage (volts)
current (Ampere)
resistance (Ohms)
Answer:
Investigué un poco y descubrí algunas cosas sorprendentes sobre los patos.Espero que los encuentres interesantes:Las aves acuáticas como los patos pueden mantener la diversidad de otros organismos, controlar las plagas, ser bioindicadores efectivos de las condiciones ecológicas y actuar como centinelas de posibles brotes de enfermedades. También proporcionan importantes aprovisionamientos (carne, plumas, huevos, etc.) y servicios culturales a las sociedades indígenas y occidentalizadas.La ubicuidad a menudo ridiculizada de los patos los convierte en vehículos ideales para transportar semillas de un lugar a otro, y eso significa humedales y biodiversidad más saludables para el beneficio de todas las aves y la vida silvestre.Sabías ? :Los patos ayudan al medio ambiente porque limpian los químicos del agua para que sus amigos y otros animales no mueran y se enfermen gravemente.
Explanation:
Answer: 10.29 sec.
Explanation:
Neglecting drag and friction, and at road level , the energy developed during the time the car is accelerating, is equal to the change in kinetic energy.
If the car starts from rest, this means the following:
ΔK = 1/2 m*vf ²
As Power (by definition) is equal to Energy/Time= 75000 W= 75000 N.m/seg, in order to get time in seconds, we need to convert 100 km/h to m/sec first:
100 (Km/h)*( 1000m /1 Km)*(3600 sec/1 h)= 27,78 m/sec
Now, we calculate the change in energy:
ΔK= 1/2*2000 Kg. (27,78)² m²/sec²= 771,728 J
<h2>If P= ΔK/Δt, </h2><h2>Δt= ΔK/P= 771,728 J / 75,000 J/sec= 10.29 sec.</h2>
Answer:
Three ways that engineers explore possible solutions in their projects are;
1) Prototyping
2) Simulation
3) Calculations
Explanation:
1) Prototyping is the process of experimental testing of samples of design, or model of a product with the possibility of the inclusion of control of parameters in order to determine the workability of a solution.
2) Simulation is the process of creating an imitation of a situation, operation or process which can be used to determine if a particular solution will be able to work as required in the simulated environment of a problem.
3) Calculations are used to find preliminary results of particular situations, their cause and effects based on scientific laws, theories and hypothesis such that the factor of the problem is equated with the available ideas to find the best possible solution.
Answer:
True
Explanation:
By definition of steady flow we have
where f(x,y,z,t) is any property of the system under consideration
=> f(x,y,z,t) = constant
