Answer:
Explanation:
As we know that the motion of the balls with respect to the position of center of mass is pure rotational motion
so here we can find the position of center of mass with respect to ball B as
also we know that the velocity of the center of mass is given as
now relative velocity of ball B with respect to center of mass is given as
now tension in the string is given as
Answer:
a. diamonds
Explanation:
solid is the matter that has definite shape and definite volume. One good example is a diamond because contains particles that are strongly attract to each other.
Answer:
Yes, wood have a fixed shape.
Explaination:
The reason is that it's solid and solids have a definite volume and shape. A piece of ice, a block of wood, and a ceramic cup are solids. They have shapes that do not change and volumes that can be measured. Any matter that is a solid has a definite shape and a definite volume.
Answer:
When the thermometer is warmed, the liquid expands by more than the volume of the hollow space in which it is confined, and so some of it must move from the bulb into the capillary tube. It should be conduction and then convection/advection, not radiation. Radiation is usually the slowest heat transfer.
