Answer:

6.6 Joules

Explanation:

Energy = power * time

= V*I*t

= 3.7 * 1.8

= 6.6 Joules

Answer:

E=23,976 J

Explanation:

Given that

I = 1.8 Ah

Voltage =  3.7 V

We know that 1 h = 3600 s

I = 1.8 x 3600 A.s

I=6480 A.s

The energy in Jules given as

E= V. I  

We know that unit of V.I is Watts ( J/s) and when multiple by seconds then we get Joules.

E=3.7 x 6480 Watt.s

E=23,976 J

Therefore the energy in joule will be 23,976 J.

Using the celsius_to_kelvin function as a guide, create a new function, changing the name to kelvin_to_celsius, and modifying th
aleksandr82 [10.1K]

Answer:

# kelvin_to_celsius function is defined

# it has value_kelvin as argument

def kelvin_to_celsius(value_kelvin):

   # value_celsius is initialized to 0.0

   value_celsius = 0.0

   

   # value_celsius is calculated by

   # subtracting 273.15 from value_kelvin

   value_celsius = value_kelvin - 273.15

   # value_celsius is returned

   return value_celsius

   

# celsius_to_kelvin function is defined

# it has value_celsius as argument

def celsius_to_kelvin(value_celsius):

   # value_kelvin is initialized to 0.0

   value_kelvin = 0.0

   

   # value_kelvin is calculated by

   # adding 273.15 to value_celsius

   value_kelvin = value_celsius + 273.15

   # value_kelvin is returned

   return value_kelvin

   

value_c = 0.0

value_k = 0.0

value_c = 10.0

# value_c = 10.0 is used to test the function celsius_to_kelvin

# the result is displayed

print(value_c, 'C is', celsius_to_kelvin(value_c), 'K')

value_k = 283.15

# value_k = 283.15 is used to test the function kelvin_to_celsius

# the result is displayed

print(value_k, 'is', kelvin_to_celsius(value_k), 'C')

Explanation:

Image of celsius_to_kelvin function used as guideline is attached

Image of program output is attached.

name the three exposure techniques in photolithography. what are the alternatives to photolithography in ic processing?
zhenek [66]

The three exposure techniques in photolithography are:

  • Contact
  • Proximity
  • Projection

Alternatives to photolithography in IC processing include;

  • X-ray
  • UV
  • Ion, and
  • Electron lithography

<h3>What is Photolithography?</h3>

Photolithography is a term in integrated circuit development that describes the patterned films that are formed when a beam of light falls on a substance.

This phenomenon protects the surface of sensitive materials such as glass during some operations like etching. UV and X-rays can be used for this purpose.

Which starting circuit uses fuses, switches, and smaller wires to energize a relay and solenoid?
zysi [14]

Answer:

Option B (Starter Control Circuit) is the right option.

Explanation:

  • This same switching is normally put upon this isolated side of something like the transmission Arduino microcontroller throughout the configuration that is using the ignition just to command the broadcast.
  • It uses a secondary relay isolated to regulate electrical current throughout the solenoid starting system.

All other given options are not related to the given instance. So the above option is correct.
