Mechanical energy can be defined as the sum of kinetic energy and the gravitational potential energy. 

Object A has kinetic energy as 604 J and gravitational potential energy as 285 J.
Hence, mechanical energy of A = 604 J + 285 J
                                                   = 889 J

Object B has kinetic energy as 481 J and gravitational potential energy as 300 J.
Hence, mechanical energy of A = 481 J + 300 J
                                                   = 781J

Hence, object A has more mechanical energy than B.

7944/0.024 = _______ give the answer to the correct number of significant figures?
In-s [12.5K]

Answer:

330,000

Explanation:

Since there are only 2 significant figures in 0.024 ( and 0.024 is the number with the least number of significant numbers), the answer is 330,000, not 331,000.

Mila [183]

Answer:

Explanation:

Half life of Nobelium-253 is 97 seconds . That means after every 97 seconds half of the Nobelium amount will be disintegrated .

Time taken in bringing the sample to laboratory = 291 seconds

291 second = 291 / 97 half life

n = 3

N = N_0 (\frac{1}{2})^n

N₀ is original mass , N is mass after n number of half life.

N = 5 mg x (\frac{1}{2})^3

= .625 mg

Only  0.625 mg of Nobelium-253 will be left .
