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
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. ... The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions.Answer:
Explanation:
Answer : The correct option is, (B)
Explanation :
Electrical energy : It is defined as the movement of the electrons thought the wire.
Chemical energy : It is a type of energy which is stored in the bonds of a chemical compounds. During the chemical reaction, chemical energy is released in the form of heat.
Sound energy : It is a type of energy which is produced when an object vibrate.
Mechanical energy : It is a type of energy that can be used to do work.
The option A is incorrect because in this process, electrical energy being converted to the sound energy.
The option B is correct because in this process, electrical energy being converted to chemical energy. An oxidation-reduction reaction occurs in the storage battery.
The option C is incorrect because in this process, mechanical energy being converted to mechanical energy.
Hence, the option (B) A storage battery is charged using an electric current is an example of electrical energy being converted to chemical energy.
Answer:
Explanation:
Power Dissipated in a resistor is given by two methods i.e.
and
where 
both formula gives Power but Former is used when voltage is constant i.e. when resistors are in parallel and the later is used when the resistor are in series .
Though can also be used in series but we have to calculate the Potential drop across each resistor then we can apply the formula.
Similar is with 
First we have to calculate current through each resistor then we can apply the Formula
According to law of conservation of momentum... as p=m.v so as velocity v increases the momentum also increases in the direction of motion
