Answer:

When appliances are linked in parallel, there is no voltage division.

Explanation:

A battery is a device that consists of one or more electrochemical cells with external connections that is used to power electrical devices such as torches and mobile phones. People frequently mistake cell and battery for the same thing. Nonetheless, it is important to understand that a cell is a single device that converts chemical energy into electricity, while a battery is a collection of cells. The benefit of connecting an electrical gadget to a battery in parallel is

When appliances are linked in parallel, there is no voltage division. The potential difference across each appliance equals the voltage provided.
By connecting electrical equipment in parallel, the overall effective resistance of the circuit can be decreased.
Other components will continue to operate even if one fails; each has its own separate circuit.
The current passing through each component is added together to generate the current flowing through the source.

Answer:

See below

Explanation:

For bulbs wired in parallel, an advantage would be that if one fails/burns out the others will continue to light .

For other appliances, if one fails the others will not be affected when wired in parallel.

You normally drive on the freeway between San Diego and Los Angeles at an average speed of 105 km/h (65 mi/h), and the trip take

valkas [14]

Answer: 2 hr 45 min

Explanation:

Given

The average speed between San Diego and Los Angeles is $105\ kmph$

time taken for this trip is $1\ hr\ 50\ min\ or\ \frac{11}{6}\ hr$

Distance between San Diego and Los Angeles is

$\Rightarrow d=105\times \dfrac{11}{6}\\\\\Rightarrow d=192.5\ km$

For Friday afternoon, the average speed is $70\ km/h$

time taken to complete the trip is

$\Rightarrow t=\dfrac{192.5}{70}\\\\\Rightarrow t=2.75\ hr\ or\ 2\ hr\ 45\ min$

A 320-g ball and a 400-g ball are attached to the two ends of a string that goes over a pulley with a radius of 8.7 cm. Because

Gnom [1K]

To solve this problem, it is necessary to apply the concepts related to force described in Newton's second law, so that

F = ma

Where,

m = mass

a = Acceleration (Gravitational acceleration when there is action over the object of the earth)

Torque, as we know, is the force applied at a certain distance, that is,

$\tau = F*d$

Where

F= Force

d = Distance

Our values are given as,

$m_1 = 0.32Kg$

$m_2 = 0.4Kg$

$d = 8.7*10^{-2}m$

Since the system is in equilibrium the difference of the torques is the result of the total Torque applied, that is to say

$\tau = T_2-T_1$

$\tau = F_2*d-F_1*d$

$\tau = m_2g*d-m_1*g*d$

$\tau = (m_2-m_1)g*d$

$\tau = (0.4-0.32)(9.8)(8.7*10^{-2})$

$\tau = 0.068N\cdot m$

Therefore the magnitude of the frictional torque at the axle of the pulley if the system remains at rest when the balls are released is $\tau = 0.068N\cdot m$
