Answer:
The induced emf for this silver circle during this period of expansion is 0.0314 V.
Explanation:
Given that,
Initial radius = 0.075 m
Magnetic field = 1.5 T
Radius = 0.125 m
Time t =1.5 s
We need to calculate the induced emf for this silver circle
Using formula of emf
Put the value ino the formula
Hence, The induced emf for this silver circle during this period of expansion is 0.0314 V.
The uncertainty of the measurement is 0.001 gm.
The uncertainty in the measurement of a physical quantity is given as how precisely we can measure that, in this case as we can see that the mass of the sodium chloride is precisely given as 29.732 gm, this means the electronic scale is precise to 0.001 gm and round of the values after that which means there is a uncertainty of 0.001 gm.
Answer:
285 Litre ( 1kg of water occupies 1 Litre )
which is identical to 285 dm^3 ie 285 cubes of length 10 cm
and as there are 10 of these linearly in 1 m then there are 10^3 = 1000 dm^3 in each m^3
giving a volume of 0.285 m^3
Of course if you KNEW that 1m^3 of water has a mass of 1000 kg then you would simply have said that the volume was 285/1000 m^3
Answer:
A rocket with more mass will speed up more slowly, just as in the horizontal example, but there is another effect. The force of gravity is now acting in the opposite direction to the thrust, so the resultant force pushing the rocket upwards is also less.

Answer:
Atacama Large Millimeter/Submillimeter Array (ALMA) Observatory's primary goal is to provide a radio telescope array that will allow scientists to observe and image galaxies out to the edge of the universe, and stars and planets in their formative stages with unprecedented clarity.
