Answer:
A. 800 J
B. - 360 J
C. 440 J
Explanation:
Applied force, F = 200 N
Friction force, f = 90 N
Distance, d = 4 m
Work done = Force x distance x cos θ
where, θ be the angle between the force and distance.
A. W = Applied force x distance = 200 x 4 x cos0 = 800 J
B. W = frictional force x distance = 90 x 4 x cos 180 = - 360 J
C. Total work done = 800 - 360 = 440 J

The answer to which type of bond shows two or more atoms baring electrons is B. Covalent
An antiparticle is a subatomic particle that, by definition, has the same mass as its normal particle counterpart but the opposite magnetic moment and electric charge. An electron's antiparticle, for instance, is the positron.
The mass of an antiparticle is equal to that of the particle version, but it has the opposite charge. Antiparticles have opposite charges, baryon numbers, lepton numbers, and strangeness. A subatomic particle known as an antiparticle has the same mass as a particle of regular matter but the opposite electric charge and magnetic moment. Thus, the positron (a positively charged electron) is the opposite of the negatively charged electron.
