To develop this problem we will apply the concept of energy conservation. For which the work carried out must be equivalent to the potential energy stored on the capacitor. We will start by finding the capacitance to later be able to calculate the energy and therefore the work in the capacitor
Here,
C = Capacitance
V = Potential difference between the plates
Q = Charge between the capacitor plates
At the same time the energy stored in the capacitor can be defined as,
We will start by finding the value of the capacitance, so we will have to,
Finally using the expression for the energy we have that,
Therefore the minimum amount of work that must be done in charging this capacitor is 
The efficiency of steam engine is 26.66 %.
<h3>What is Efficiency?</h3>
The efficiency is defined as the work done by the engine divided by the heat supplied.
Work done is the difference between the heat supplied and heat rejected.
So, efficiency η = (Qs -Qr) / Qs
Given is the heat supplied Qs = 225 Joules and heat rejected Qr =285 . then the work done is
W = 225 -225 = - 60 Joules
Efficiency η = 60/225 x 100%
η = 26.66 %
Thus, the efficiency of the steam engine is 26.66 %.

Answer: Worm
A virus spreads from one machine to another rapidly without human action. A virus is like a code that runes automatically without any knowledge or without taking permission of the user. It hampers the way a machine works. When a machine is attached to another machine directly or indirectly containing virus, it spreads itself. A worm is a kind of virus that can spread with zero human intervention. A virus still requires a human to download a contaminated file but worm does not. a worm can spread on its own
Answer:
39.4 g
39.4 cm³
1.09137 g/cm³
Explanation:
= Density of water = 1 g/cm³
Mass of water displaced will be the difference of the
Mass of water displaced is 39.4 g
Density is given by
So, volume of bone is 39.4 cm³
Average density of the bird is given by
The average density is 1.09137 g/cm³
Here, we can use the resolution of vectors to find the component in the y-axis of the distance traveled by Jin. The southern component is given by:
s = dsin(∅), where s is the southern component, d is the distance traveled and ∅ is the angle below east at which it was traveled.
s = 4sin(30)
s = 2 km
