Answer:
W = 71J
Explanation:
Given force F = (5i+5j−1k)N
d = Δr
r1 = (−5,−3,−4)m
r2 = (2,5,0)m
Δr = r2 – r1 = (2-(-5), 5-(-3), 0-(-4))
Δr = (2+5, 5+3, 0+4) = (7i+ 8j +4k)m
W = F•d = (5i+5j−1k)•(7i+ 8j +4k)
W = 5×7 + 5×8 +-1×4 = 35 + 40 - 4
W = 71J
Answer:Technician A
Explanation:
Technician A is right as a 12 v battery contains 6 cells of 2.2 volts and
The size of the battery plates and amount of electrolyte decides the amount of charge lead acid batteries can store for example thus more plates a cell does not mean more voltage it creates.
Diffraction patterns are due to interference<span>. Diffraction is a phenomena which occurs when a wave encounters an obstacle. It is the bending of light around the corners if the obstacle.</span>
Answer:
Explanation:
Nuclear Fission -
The process of the splitting of atom , by radioactive decay process or by any collisional impact .
Sun contains many radioactive isotopes like , thorium , uranium , etc .
The nuclear fission process is an intrinsic property of the radioactive nuclides.
Nuclear Fusion -
The process , where two or more than two atomic nuclei combines to form one or more different atomic nuclei and subatomic particles .
The energy released in both the process is almost same ,
But on the surface of Sun , hydrogen is abundantly present , hence , hydrogen fusion is possible , so the dominant source of energy on the sun is Fusion .
