Answer: Only Tech B is correct.

Explanation:

First, tech A is wrong.

The circuits that can be compared with links in a chain are the series circuit, and it can be related to the links in a chain because if one of the elements breaks, the current can not flow furthermore (because the elements in the circuit are connected in series) while in a parallel circuit if one of the branches breaks, the current still can flow by other branches.

Also in a parallel circuit, the sum of the currents of each path is equal to the current that comes from the source, so Tech B is correct, the total current is equal to the sum of the currents flowing in each branch of the circuit.

Vibration of an object about an equilibrium point is called simple harmonic motion when the restoring force is
den301095 [7]

Answer:

Displacement

Explanation:

An object exhibiting simple harmonic motion, the restoring force is directly proportional to the displacement of the object. The direction of direction of the force is in opposite direction of the displacement. It is given by :

F=-kx

k is the spring or force constant

x is the displacement

So, the correct option is (b) "displacement".

(a) How much helium (density 0.18 kg/m3) is needed to lift a balloon carrying two people, if the total mass of people, basket, a
andreyandreev [35.5K]

Answer:

(a) 1555.6m^3

(b) 17284m^3

Explanation:

Density of helium=0.18kg/m^3, density of hot-air balloon=0.18-(0.1×0.18)=0.18-0.018=0.162kg/m^3, total mass of people, basket and balloon=280kg

(a) volume = mass/density=280/0.18=1555.6m^3

(b) volume = mass/density = 280/0.162= 1728.4m^3
