Electric Charge Conserved means that no case has ever been found.

Explanation:

The electric power can neither be built nor destroyed.
But it can be saved and used whenever required, the closed-circuit system is movement of charges tends to current, which means the flow of charge, but the charges are still existing in the closed system, the charges in the isolated does not changes and it is always filled with charges, only on power trigger the charges moves.
Found in material like copper, iron, etc.
This is based on the rule of conservation of power that defines that, power can neither be built nor it can be destroyed, but it can be transformed into one order to another order.
Hence this case is found in all electrical circuits.
This fails in nonconductors like wooden, glass and plastic with no flow of charges in them.

A car with four passengers will have a shorter braking distance than a car with one braking distance. True or false. Why?

Valentin [98]

Answer:

The given statement is a True statement

Explanation:

All cars and trucks have load capacities marked on the jamb of the driver's door, as well as the owner's manual. This is very significant for braking distance.

A heavier object will require much more braking force and distance to stop, due to New ton's law of motion. “ An object in motion will tend to stay in motion “ .A heavy object will remain in motion longer and require much more force to stop. Four wheel disc brakes are great compared to front disc and rear drum configuration, in dissipating heat, and stopping more efficiently.

On a certain planet, which is perfectly spherically symmetric, the free-fall acceleration has magnitude g = go at the north pole

ohaa [14]

The reason why there is a difference between free-fall acceleration is a centrifugal force.
I attached a diagram that shows how this force aligns with the force of gravity.
From the diagram we can see that:
$F=F_g-F_{cf}=mg'-mw^2r'cos(\alpha)\\ ma=mg'-mw^2r'cos(\alpha)\\ a=g'-w^2rcos^2(\alpha)\\$
Where g' is the free-fall acceleration when there is no centrifugal force, r is the radius of the planet, and w is angular frequency of planet's rotation. $\alpha$ is the latitude.
We can calculate g' and wr^2 from the given conditions in the problem.
$g(90)=g_0;\ g_0= g'-w^2rcos^2(90)\\
g_0=g'\\
g(0)=ag_0;\ ag_0=g_0-w^2rcos^2(0)\\
ag_0=g_0-w^2r\\
w^2r=g_0(a-1)
$
Our final equation is:
$g=g_0-g_0(a-1)cos^2(\alpha)$
Colatitude is:
$\alpha_c=90^\circ-\alpha$
The answer is:
$g=g_0-g_0(a-1)cos^2(90-9)=g_0-g_0(a-1)sin^2(9)$
