The answer for this question is o power
Answer:
Q = 640425 J = 640.425 KJ
Explanation:
From the law of conservation of energy:
Heat Addition = Heat Gain of Water + Heat Gain of Aluminum Kettle
where,
Q = Heat addition required = ?
= mass of water =1.8 kg
= mass of aluminum kettle = 1.1 kg
= specific heat capacity of water = = 4200 J/kg.°C
= specific heat capacity of aluminum kettle = = 890 J/kg.°C
= = change in temperature of water and kettle = 95°C - 20°C = 75°C
Therefore,
Q = 567000 J + 73425 J
<u>Q = 640425 J = 640.425 KJ</u>
Answer:
Explanation:
The expression for the deBroglie wavelength is:
Where,
is the deBroglie wavelength
h is Plank's constant having value
m is the mass of the matter associated with Earth
Mass of Earth =
v is the speed of the matter associated with Earth.
Velocity of Earth =
Applying in the equation as:
The wording of this can be bothersome. I think you should be using
E = F * d
E = 68 J
d = 12 m
F = ???
68J = F * 12 m
68J/12 m = F
5.67 N

Answer:
Preassure plate
Explanation:
The flywheel, clutch disc, pressure plate, throw-out bearing clutch fork, and the pilot bearing are the components of a clutch. It works when the flywheel bolts onto the crankshaft and therefore the <em>pressure plate bolts back into the flywheel.</em>
