In a series circuit, all of the components are connected in the same 'loop' and the current only has one direction/path it can flow through.

In the first three options, the current has multiple paths it can go through. So these three circuits are parallel and not series.

In the last option, the current only has one path where it can flow through, so that circuit is in series.

So Circuit D is a series circuit.

Answer:the last one

Explanation:in a series circuit, only one current flows through it. i.e it connected by a single wire

MArishka [77]

The liquid that will evaporate the quickest would be water.
~The rest are mixtures, and have more ingrediants in them, therefore the answer should be water. (in which it has no other ingrediants in it but water itself)

Distanţa Buzău - Iaşi este de 72 km . Aflaţi timpul în care un autovehicul parcurge această distanţă, dacă are viteza de 72 km p

GrogVix [38]

The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you

Answer:

3600seconds

Explanation:

Given parameters:

Distance = 72km

Speed = 72km/hr

Unknown:

Time it takes for the vehicle to travel the distance = ?

Solution:

Speed is the distance divided by time;

Speed = $\frac{distance}{time}$

time = $\frac{distance}{speed }$

Insert the parameters;

time = $\frac{72}{72}$ = 1hr

The SI unit of time is in seconds;

3600 seconds is 1hr

The time is 3600seconds

A book falls of the table and hits the floor. Is work done? Why?

morpeh [17]

Yes, work is done when a book falls of the table.

This is because:

When the book falls, it's potential energy is converted into kinetic energy. As it reaches the floor down, this kinetic energy is converted to heat energy and sound energy due to the impact.

When a force is imposed on an object to cause displacement of that object, work is done on that object. For a force to do work on an object, there should be a displacement and this force should cause the displacement. So here, since the book falls from the table and causes the displacement of the book from the table to the floor. It is said that work is done.

Work can be given by the formula:

W = F • d

where F is the force and d is the displacement.

A rock falls from rest off a cliff and hits the ground in 2 seconds. If there is no air resistance, determine the rock's velocit

mihalych1998 [28]

Answer:

19.6m/s

Explanation:

A Rock falling off a cliff can be modeled as an object starting with zero velocity moves with constant acceleration for certain period of time, for such motion following equation of motion can be used.

$v(t) = v_{0} +at$

here in our case $v_{0} =0$ because object starts off from rest and $a = g =9.8m/s^2$ is acceleration because of gravity ( Motion under gravity).

and of course t = 2 second.

Now by substituting all this information in equation of motion we get.

$v(2s) = 0+9.8m/s^2 *2s = 19.6m/s$

that would be the velocity of rock as it would hit the ground.

Note! We have assumed that there is no air resistance.
