Answer:
Explanation:
Given
W amount of work is done on the system such that it acquires v velocity after operation(initial velocity)
According to work energy theorem work done by all the forces is equal to change in kinetic energy of object
where m=mass of object
v=velocity of object
When the object is already have velocity v then the final speed is given by work energy theorem
From 1 and 2 we get
Metal cooking pots and pans often have wooden handles. Wood has a higher specific heat than metal, so it takes more energy to heat a wooden handle than a metal handle. As a result, a wooden handle would heat up more slowly and be less likely to burn your hand when you touch it.
Answer:
Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density. ... Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.
Explanation:
Answer:
NO decimals after the decimal place.
Explanation:
Recall that the rule for addition of values for measured quantities specifies that the total should be rounded to the number of decimal of the quantity with the less resolution (number of decimals). Then, the given addition should carry NO decimals after the decimal point, limited by the second value added (15) which carries no decimals.
The first diagram will have the strongest attraction because it is the closest
