Using the equation;
TE = 1/2mv^2(1+2); where k = 2/5 for a solid sphere; V is the velocity, and m is the mass.
Total energy = 0.5 × 21 × 8² (7/5)
= 940.8 J
The rotational kinetic energy of the sphere is 940.8 J
Answer:
Silver halide or silver salt is mostly used in photographic films
Explanation:
Silver halide crystals in gelatin are coated onto a film base, glass or paper substrate. And when a sliver halide crystal is exposed to light (photons strike) it turned into a small speck of metallic crystal and these comprise the invisible or latent image which is developed afterwards.
Answer:
<em><u>To be neutral</u></em>
Explanation:
Neutrons are electrically neutral but contribute to the mass of a nucleus to nearly the same extent as the protons. Neutrons can explain the phenomenon of isotopes (same atomic number with different atomic mass). The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.
Answer:
foam but thats what i heard from other people
Explanation:
Answer: The correct answer is : B. transduction
Explanation: Transduction is a process through which DNA is transferred from one bacterium to another through the action of a virus or a viral vector. There are two types of transduction, the generalized and the specialized. Transduction is a tool widely used by molecular biologists.
