<u>Answer:</u>
<em>To relate the type of box material to the warmth inside the box
</em>
<u>Explanation:</u>
3 boxes are made with three different materials glass, plastic and Aluminium. Thermal conductivity is different for different materials. thermal conductors allow easy flow of heat through them and insulators allow minimal or no flow of heat through them.
Thus the amount by which an object gets heated up depends on the value of its conductivity. In this experiment, glass and plastic are insulators and aluminium is a conductor. Among glass and plastic, plastic is a better insulator.
<em>Thus the heat contained in the boxes will be of the order </em>Aluminium>glass>plastic.
Answer:
Explanation:
For circuit in resonance , inductive and capacitive reactance should be equal. Since in the given circuit , these two are not equal, the circuit is not in resonance. It does not depend upon voltage provided.
option b is correct.
With this load, the fraction of the average power, put out by the source of emf, delivered to the load can be calculated as follows
Power delivered to resistor will be 2/3 rd of total power delivered by source because resistance has value twice that of reactance of capacitor. So the correct option is .7
option D ) is correct.
Answer:
Strato-volcano
Explanation:
Strato-volcanoes are usually characterized by the presence of steep-sided slopes, with distinct craters, and are frequently erupted and conical in appearance. This type of volcano is generally felsic in nature. Due to the presence of high silica content, the magma being highly viscous, moves at a relatively slower rate. These are highly explosive and produce a large number of pyroclastic materials, lava flow, volcanic ashes, and gases.
They are also commonly considered as the composite volcano, and are comprised of alternating tephra and solidified lava layers.

Answer:
maximum possible speed by solving above equation for 7D is

minimum possible value of speed for solving x = 6D is given as

Explanation:
Let the nozzle of the hose be at the origin. Then the nearest part of the rim of the tank is at (, ) = (6, 2) and the furthest part of the rim is at (, ) = (7, 2).
The trajectory of the water can be found as follows:


Now from above two equations we have

now we know that height of the cylinder is 2D so we have

by solving above equation we have

now we know that maximum value of x is 7D
so the maximum possible speed by solving above equation for 7D is

minimum possible value of speed for solving x = 6D is given as
