Answer:

Circuit A is a series circuit

The total resistance in Circuit A is greater than that in Circuit B

Explanation:

Circuit A is a series circuit due to its arrangements. The current flowing through the loads in a series circuit is always the same due to absence of branch compared to parallel circuit that possesses branches between the loads (resistors).

Also, the effective resistance in a series circuit(Circuit A) is greater because the effective resistance of a series connected loads is the sum of the individual resistances compared to parallel circuit (Circuit B) that its effective resistance is the sum of the "reciprocal" of its individual resistances. Taking the reciprocal of a number always reduces the value of such number hence the reason behind parallel circuit having less effective resistance compare to the series connected loads.

Answer:

Circuit A is a series circuit

The total resistance in Circuit A is greater than that in Circuit B

Explanation:

The missing diagram is here attached. For circuit A, considering that in a series circuit, the current through each load is the same and the total voltage across the circuit is the sum of the voltages across each load. Moreover, current flowing through each resistor in a parallel circuit is different, depending on the resistance. Therefore, we can say that when resistors are connected in parallel, more current flows from the source than flow for any of them individually, so the total resistance is lower.

There are several many equations that are available to relate the distance,
speed, and time of a body moving vertically in gravity. Happily, the only one
I can always remember without looking it up happens to be the right one to
use for this question !

   Distance = (1/2) x (gravity) x (time)²

   3.8 m = (1/2) x (9.8 m/s²) x (time)²

Divide each side
by 4.9 m/s² :

   (3.8 m) / (4.9 m/sec²) = (time)²

   0.7755 sec² = time²

Square root
of each side:

   0.88 second = time

a 1.2 m wire carries a current of 10.0 A in a uniform magnetic field of 0.050T. Find the magnitude of the magnetic force on the

rodikova [14]

To calculate we use the formula for a magnetic force in a current-carrying wire expressed as the product of the current, magnetic field and the length of the wire.
F = I x L x B

where F is the force on the wire, I is the current flowing on the wire, L is the length of the wire and B is the magnetic field.

F = 10.0 A x 1.2 m x 0.050 T
F = 0.60 N

In certain cases, using both the momentum principle and energy principle to analyze a system is useful, as they each can reveal

kramer

Explanation:

The gravitational force equation is the following:

$F_G = G * \frac{m_1 m_2}{r^2} \\$

Where:

G = Gravitational constant = $6.67408 * 10^{-11} m^3 kg^{-1} s^{-2}$

m1 & m2 = the mass of two related objects

r = distance between the two related objects

The problem gives you everything you need to plug into the formula, except for the gravitational constant. Let me know if you need further clarification.
