Driving a motor........
chemical energy is converted into kinetic energy.
Falling off of cliff
.........gravitational potential energy is converted into kinetic energy.
Hydroelectric energy generation
.......gravitational potential energy is converted into kinetic energy (i.e. driving a generator), which is then converted into electrical energy.
Nuclear power generation
.........mass is converted into energy, which then drives a steam turbine, which is then converted into electrical energy.
Answer:
2.26l
Explanation:
From the general gas equation:
P1V1/T1 = P2V2/T2
Since pressure remained constant we can say:
V1/T1 = V2/T2
so to convert to kelvin add 273 to both temperature values then we can say:
1 m^3= 1000 L
2l=0.002m^3
Then;
0.002/308=V/348
V=(0.002/308)348
Final volume=0.002259m^3
=2.6l(1 decimal place)
Equations of the vertical launch:
Vf = Vo - gt
y = yo + Vo*t - gt^2 / 2
Here yo = 35.0m
Vo is unknown
y final = 0
t = 4.00 s
and I will approximate g to 10m/s^2
=> 0 = 35.0 + Vo * 4 - 5 * (4.00)^2 => Vo = [-35 + 5*16] / 4 = - 45 / 4 = -11.25 m/s
The negative sign is due to the fact that the initial velocity is upwards and we assumed that the direction downwards was positive when used g = 10m/s^2.
Answer: 11.25 m/s
Conduction is a mode of transfer of heat there
I’m confused about this question
