a rectangular block is having 5cm,5cm and 8cm with density of 7.).5g/cm^2. what is the mass of the block​
Art [367]

Answer:

Explanation:

Volume of the rectangular block= V = l×b×h

=5cm×5cm×8cm= 200cm³

Density of block= d= 7.5 g/cm³

Mass of the block= m= d× V

= 1500 grams=1.5 kg

navik [9.2K]

Answer:

U = 8.30×10-⁹J

Explanation:

m1 = m2 = 5.00kg masses of the spheres

d = 15.0cm = 15×10-²m

r = 5.10cm = 5.10×10-²m

R = d + r = 15×10-² + 5.10×10-²

R = 20.10 ×10-²m = 0.201m

G = 6.67×10-¹¹Nm²/kg²

U = Gm1×m2/R = potential energybetween the spheres

U = 6.67×10-¹¹×5.00×5.00/0.201

U = 8.30×10-⁹J

Example of nuclear fission and nuclear fusion​
EleoNora [17]

Answer:

In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.
