Explain the difference between an ignition transformer and a solid-state igniter
bazaltina [42]

Ignition transformer

1.      Weight of the transformer is more.

2.      Voltage output of the transformer is from 10,000 volts to 14,000 volts.

3.      Due to lower voltage output, fuel vaporization and ignition will be slow.

4.      When there is a drop in voltage supply, the transformer gets affected.

5.      Consumption of electricity is more.

 

Solid state igniter.

1.      Igniter weighs very light

2.      Igniter giver voltage output in the range of 14,000 volts to 20,000 volts

3.      Higher voltage output leads to faster vaporization of fuel and ignition

4.      Very small affect is observed when there is a voltage drop.

5.      Less electricity is consumed.

IS IT TRUE?that the moon collided with a tiny plant made of rubble from earth's collision with another planet that made the moon
Nikolay [14]
That is currently unknown, because we don't have anyone who lived them with that knowledge, but based on some facts of Guessing. I would say yes, because another planet near Earth right, well from what I heard, the asteroid that killed the dinos, had another part recoil back into space, and could have hit another part of the asteroid.

What is the ratio (in the form of a decimal) of the root-mean-square speed of 238UF6 to that of 235UF6 at constant temperature?
NNADVOKAT [17]

Answer:

ratio=0.996m/s

Explanation:

RMS=\sqrt{\frac{3RT}{M} }; M= molecular weight of compound;

RMS speed is inversly proportional to the molecular weight hence compound having less molecular weight will have more rms speed value.

V1 for 238 UF_{6}; M1=238+114=352g/mole

V1 for 235 UF_{6}; M1=238+114=352g/mole

V1=\sqrt{\frac{3RT}{352} };

V2=\sqrt{\frac{3RT}{349} };

\frac{V1}{V2}=ratio of 238UF_{6} F6 to 235UF_{6}=\sqrt{\frac{349}{352} };

\frac{V1}{V2} =0.9957m/s;

\frac{V1}{V2} =0.996m/s;

what is the amount of heat energy released when 50.0 grams of water is cooled from 20.0 degrees Celcius to 10.0 degrees celcius
andre [41]

Answer:

The amount of heat released when 50 g of water cooled from 20°C to 10°C will be equal to  - 2093 J.

Explanation:

Given data:

Mass of water = 50 g

Initial temperature= T1 = 20°C

Final temperature= T2 = 10°C

Specific heat of water= c = 4.186 J/g. °C

Amount of heat released = Q= ?

Solution:

Formula:

Q = m. C.  ΔT

ΔT = T2 - T1

ΔT = 10°C - 20°C

ΔT = -10°C

Now we will put the values in formula.

Q = m. C.  ΔT

Q = 50 g .  4.186 J/g. °C . -10°C

Q =  - 2093 J

The amount of heat released when 50 g of water cooled from 20°C to 10°C will be equal to  - 2093 J.
