Answer: It is D (The average kinetic energy of the particles)
Explanation:
I don’t know what you mean by “give me a reason to live as well” but I think you should live because even though it is hard sometimes there will always be someone that cares about you and would never know what life would be like without you even if you may not have found that person yet they are somewhere in the world and you just need you keep going and find that special person! Hope this helps!
Its because of the static electricity.As we rub, the positive and negative charges are acquired by the plastic rod and duster.
If we bring paper bits near them, the charges possessed by the paper bits get attracted towards the charges in plastic rod.
Given parameters:
Volume of water in the tank = 750litres
Length of the tank = 150cm
Breadth of tank = 50cm
Unknown:
Height of the tank = ?
To solve this problem, we must understand the concept of volume. Volume is a property of solid bodies. It is mathematically derived as:
Volume = length x Breadth x height
The unknown here is the height and we should go ahead to solve for it.
<em>But the units are inconsistent. </em>
Therefore, convert litres to cm³;
1 litre = 1000cm³
750 litres = 1000 x 750 = 750,000cm³
Now input the parameters and solve for the height;
750000 = 150 x 50 x height
height = = 100cm
Therefore, the height of the tank is 100cm
Answer:
Q = 425 kJ
Explanation:
Given that,
Mass, m = 25 kg
The clown doll head that heats up from 25°C to 35°C
The specific heat is 1700 J/kg°C
We need to find the internal energy of it. The heat required to raise the temperature is given by the formula as follows :
So, 425 kJ of thermal energy is severed.
