Answer:

I wouldnt say SI unit isnt important but the Metric System certainly is. And Metric System is more closer to SI unit than imperial unit. Amongst many , the most important one is the ease of use. We upgraded the number system to base 10, why hesitate to import the measurement units to base 10.

Explanation:hop this thelps you !!! :0 :)

SI unit is an international system of measurements that are used universally in technical and scientific research to avoid the confusion with the units. Having a standard unit system is important because it helps the entire world to understand the measurements in one set of unit system.

A net force of 3000 N is accelerating a 1200 kg elevator upward. If the elevator starts from rest, how long will it take to trav
alexdok [17]

F = net force acting on the elevator in upward direction = 3000 N

m = mass of the elevator = 1200 kg

a = acceleration of the elevator = ?

Acceleration of the elevator is given as

a = F/m

a = 3000/1200

a = 2.5 m/s²

v₀ = initial velocity of the elevator = 0 m/s

Y = displacement of the elevator = 15 m

t = time taken

Using the kinematics equation

Y = v₀ t + (0.5) a t²

15 = (0) t + (0.5) (2.5) t²

t = 3.5 sec

A coil is connected in series with a 12.6 kΩ resistor. An ideal 65.2 V battery is applied across the two devices, and the curren
ivolga24 [154]

To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.

PART A)

i = i_0 (1-e^{-t/T})

i = (V/R)(1-e^{-t/T})

0.00402 = (65.2/12600)(1-e^{-0.00402/T})

T = 0.002679s

T = L/R

Inductance can be defined then,

L = RT

L = (12600)(0.002679)

L = 33.75H

PART B) Now the energy is given under the terms:

E = \frac{1}{2}Li^2

E = \frac{1}{2} (33.75)(0.00402)^2

E = 0.0002727J

Therefore the energy stored in the coil at this same moment is 0.0002727J
