Answer:
* thermal energy
potential energy,
potential energy
Explanation:
The ship has various types of energy,
* thermal energy. This energy is associated with the temperature of the coal, the hotter the greater its internal energy,
* potential energy this energy is stored in the constituent atoms within carbon
* potential energy. It is due to the configuration of the system, in this case the sun heats the coal
<span>Nonliving things also have unlimited duration of existence. While living things die and decompose, nonliving things such as rocks, mountains, air and water have existed for millions of years. They may grow, but they do so only by accretion, which is the process of growth by accumulating added layers of matter.</span>
Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
Answer:
b. Both the gratings will produce the same separation of peaks.
e. The grating with 10 slits will produce better-defined(narrower) peaks.
Answer:
The value of the electric field is 
Explanation:
We know that the electric field inside a solid cylinder at a distance 
from the centre is given by
Let's consider the cross-section of the cylinder as shown in the figure. Let `O' be the centre of the long solid insulating cylinder having radius 'R'. Also consider that 
be the cetre of the hole of radius 'a' situated at a distance 'b' from 'O'. Given, the volume charge density of the material is 'r'. So, the volume charge density inside the hole will be '-r'. Let's consider 'P' be any arbitrary point inside the hole situated at a distance 's' from .
So, the electric field '
' due to the long cylinder at point 'P' is given by
and the electric field '
'due to the hole at point 'P' is given by
So the net electric field (
) inside the hole is given by
