Answer:
A) Cold object will start getting hot
B) Heat exchange will stop as the two object acquire the same temperature.
Explanation:
A) When one hot object and one cold object are kept in contact then the heat is transferred from the hot object to the cold object via different modes of heat transmission. Hence, the cold object starts getting hot
B) The transmission of heat from the hot object to the cold object will stop as the temperature of the two object becomes equal to each other.
Answer:
Explanation:
Given
height of building h=3 m
Landing velocity of diver at an angle of
Let u be the initial velocity of diver at an angle of \theta with horizontal
Since there is no acceleration in horizontal direction therefore horizontal component of velocity will remain same
---- -----1
Considering Vertical motion
here
----------------2
Divide 2 and 1 we get
Thus
Look up what there both made out of and it will tell you but basically it’s b/c of what there made out of and the chemicals in the tea (drink)
Answer:
The five steps for determining density can be found in simple form as follows, measure the mass of the container, measure the volume of the liquid(s), measure the combined mass of the liquid and the container, and then determine the mass of the liquid alone and divide the mass by the volume of it.
This collects light, and bends it into focus.
