Explanation:
The electric field of an isolated charged parallel-plate capacitor is given by :
........(1)
Where
q is the electric charge
A is the area of cross section of parallel plate
It is clear from equation (1) that the electric field of a parallel plate capacitor is directly proportional to the charge on the plate and inversely proportional to the area of cross section of a plate.
So, the correct option is (E) i.e. "none of the above".
Stop using it all the time for some useless things.
To solve this problem we will apply the concepts related to the conservation of momentum. The momentum can be defined as the product between the mass of the object and its velocity, and the conservation of the momentum as the equality between the change of the initial momentum versus the final momentum. Mathematically, this relationship can be described as

Here,
= Mass of each object
= Initial velocity of each object
= Final velocity of each object
According to the statement one of the bodies does not have initial velocity, therefore said term would be zero. And the equation could be rewritten as,

Replacing the values respectively (The mass of your body with its respective speed we would have)



Therefore the initial velocity of the 2kg cart is 0.55m/s
Answer: Hydroplaning
Explanation: Hydroplaning is the skiding of a high speed vehicle when water builds beneath the wheels when driving through standing water.
It is usually caused by factors such as High speed,Standing water,deflated tyres. It is strongly recommended that when driving in standing water a driver should drive at a slow and steady speed and always to ensure that the vehicle tyres are adequately inflated with air,this is one of the causes of vehicular accidents during rainy season or flood.
1. I don't see a graph
2. It could be because a liquid could be evaporating in the process
3. It could be that the liquid is getting colder
4. 1 liquid is medium and moving a the normal pace
