The following expression is applicable:
Max. inductor energy = Max. capacitor energy
Where;
Max. inductor energy = LI^2/2, with L = 20.0 mH, I = 0.400 A
Max. capacitor energy = CV_max^2/2, C = 0.150 micro Faraday, V_max = Max. potential difference
Substituting;
LI^2/2 = CV^2/2
LI^2 = CV^2
V^2 = (LI^2)/C
V_max = Sqrt [(LI^2)/C] = Sqrt [(20*10^-3*0.4^2)/(0.15*10^-6)] = 146.06 V
Answer:
a. The acceleration would increase.
Explanation:
because we know that
F=ma
m= mass and a= acceleration
so Mass is same for the cart in any situation that's why only acceleration could increase.
Isothermal process<span> is a </span>change<span> of a </span>system<span>, in which the </span>temperature<span> remains constant: Δ</span>T<span> = 0. So, if the thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged than this process is isothermal.
</span><span>The Joule's second Law states that the internal energy of a fixed amount of an ideal gas depends only on its temperature. So, isothermal processes are of great interest for ideal gasses.</span>
Answer:
The product of mass times velocity for both objects is the same.
Explanation:
They both have the same velocity. False
They both have the same mass. False: Because two objects of different masses can have the same momentum. The least massive of the two objects will have the greatest kinetic energy.
The product of mass times velocity for both objects is the same. True: Same momentum means that the large mass must have a small velocity; therefore, their product is equal to the small mass times a large velocity.
Mass and velocity is the same for both. False: Based on what was stated for the second option.
Answer:
e. it expands in horizontal direction
Explanation:
By the law of thermal expansion of metals we know that when a metal is heated it expands due to the thermal properties of its molecules.
<u>Mathematically this expansion in its length is given by:</u>
where:
original length of the metallic piece
coefficient of linear expansion
rise in temperature
- Here, in the given question we have a bimetallic strip with one end attached to the wall rigidly so that it is in horizontal orientation.
- Upon heating the strip gains the temperature and expands horizontally along the length because it is <em>fixed to the wall only from one end.</em>
