Answer:

a simple machine has way less parts than a complex machine like just one pulley or lever. A complex machine has multiple different parts that lead up to one thing being done in the long run.

Explanation:

Simple Machine: Any of various devices that function in a manner basic to any machine, such as a lever, pulley, wedge, screw, or inclined plane. Complex Machine: A device consisting of two or more simple machines working together. ... A wedge is driven or forced between objects to split, lift, or make them stronger.

an 18 ohm resistor and a 6 ohm resistor are connected in parallel to a battery, and the current in the 18 ohm resistor is found
riadik2000 [5.3K]

With 0.45 amp flowing through an 18-ohm resistor, the voltage across it is

       V  =  I R  =  (0.45) x (18)  =  <em>8.1 volts .</em>

"But I asked for the battery voltage!  That's the voltage across the resistor."

The ends of the resistor are connected directly to the battery terminals.
They're the same voltage.

"But what about the 6-ohm resistor ?  Where does that figure in ?"

In parallel, it doesn't.  It's also connected directly across the battery,
and it has its own current. 

In parallel, neither resistor knows or cares whether or not there are
any other resistors present.  In parallel, it makes no dif.

What minimum heat is needed to bring 250 g of water at 20 ∘C to the boiling point and completely boil it away? The specific heat
Amiraneli [1.4K]

Answer:633.8 KJ

Explanation:

Given

mass of water\left ( m\right )=250gm

Initial temperature\left ( T_i\right )=20^{\circ}C

Final temperature \left ( T_f\right )=100^{\circ}C

Specific heat of water \left ( c \right )=4190 J/kg-k

heat of vaporization\left ( L\right )=22.6\times 10^5 J/kg

Heat required for process\left ( Q\right )=heat to raise water temperature from 20 to 100 +Heat to vapourize water completely

Q=mc\left ( T_f-T_i\right )+mL

Q=0.25\times 4190\times \left ( 100-20\right )+0.25\times 22\times 10^5

Q=\left ( 0.838+5.5\right )\times 10^5

Q=6.338\times 10^5J=633.8 KJ
