Hello There
Answers:
1) BEVs and hydrogen fuel cell vehicles are more promising for the future because they reduce gas emissions as well as CO2 which makes our planet less-pulluted
2) This is an opinion. Mine is that they should be required to at least have it be an option to buy.
I hope this helps

Answer:
a).
b).
Explanation:
a).
Using the law of thermodynamic and using to isovolumetric
ΔU=Qh

So to determine the internal energy knowing the work it do

b).
Efficiency is the work done in relation of the work apply in this case to produce heat so:

Solve to Qc
![Q_{c}=Q_{h}*[1-E]](https://tex.z-dn.net/?f=Q_%7Bc%7D%3DQ_%7Bh%7D%2A%5B1-E%5D)


The angular velocity at the beginning of the interval of the wheel rotating at a constant angular acceleration is determined as 10 rad/s.
<h3>
Initial angular velocity of the wheel</h3>
The initial angular velocity of the wheel is determined by applying the kinematic equation as shown below;
ωf² = ωi² + 2αθ
where;
- ωf is the final angular velocity
- ωi is the initial angular velocity
- α is angular acceleration
- θ is angular displacement
Substitute the given parameters and solve for the initial angular velocity.
14² = ωi² + 2(6)(8)
196 = ωi² + 96
ωi² = 196 - 96
ωi² = 100
ωi = √100
ωi = 10 rad/s
Thus, the initial angular velocity of the wheel is 10 rad/s.

Answer:
The buoyant force is the pressure of the object being forced upward.
<em>Weight of the object affects the buoyant force</em> of the submerged object; as weight is added to the object, it will cause the object to sink. The more weight...the more it will sink.
If the weight is less than the buoyant force, it will cause the object to go up.
If the weight is the same as the buoyant force, the object will stay in the same position.

Answer:
6.2j
Explanation:
work done=force × displacement
wd=11N×0.56m
wd=6.16N/m~6.2j
