Next

Wrong answer. Carefully read the instructions.

Again

Arrange

Properly arrange the labels.

Check

 
Matching can also be made with images.

Correct.

Alpha particle

Figure shows an alpha particle. Alpha particle is a helium nucleus.

How many protons has an alpha particle? How many neutrons has an alpha particle?

Check

You can make questions with numerical answers, where the user writes the right anwser in the box provided.

Correct!

Next

The anwser is still not correct. Number of protons is 2 and the number of neutrons is also 2.

Next

The answer is wrong. Try again.

Shape of the jet

A water jet maintains a constant the flow rate. Select the equation that describes the conservation of the flow rate. Points 1 and 2 are marked on the image.

(/files/112/pipa1.png)

The answer is correct!

Next

The answer is incorrect. The flow is defined as:

.

Again

Again, you did not answer correctly.

We know: . Connection can be derived from the definition of the flow

You can add images to make the exercise clearer.

You must answer the question.

Again

Radius: m.

Angle: .

Red circle

Watch the red circle from beginning to end movement. Which statement about the cycle is correct?

The movement from the initial position is

5
7

The answer is correct. The initial position is and the final is .

Next

The answer is incorrect.

Again

The initial position is and the final is . Move the circle is .

Circuit

Take a good look at the circuit in the photo. Predict how the lamps A, B and C will light, after connecting the upper left crocodile at the free connector of the left battery. The resistance of the wires is negligible.

(/files/112/vezjaABCD1.png)

Select from the following numbers in the table:
-bulb is strongly lit,
-bulb is weakly lit,
-bulb is not lit.

A 0 1 2
B 0 1 2
C 0 1 2
D 0 1 2

Check

 
Another option for the questions are the ones, where the possible answers are given in a drop-down menu.

The answer is correct.

Next

The answer is incorrect. Hint: The circuit is a seguence binding together two light bulbs and circuits in which the remaining bulbs are connected in parallel.

Tra again

The circuit is a sequence binding bulbs A and B, and the circuit in which C and D are bound in parallel. Therefore, through the A and B running full flow through C and D through only half the flow that is driven by batteries.

Car making a turn

 
Using tools over the images you can create many dynamical exercises.

We make a turn with a car, as shown in the image. With the help of the tools on the image, measure the radius of the loop.

m

While searching for the radius of the loop it is cruical to understand, that the loop is just a part of the circumference.

We expect some users to have issues with determining where is the radius of the circumference. Therefore we should help ourselves with the image of the circumference wirh the radius drawn in it. We take radius with values between 42 and 52 as correct.

Next

Excellent! We can continue.

Next

The result of the measurement is false. Correct result is m m.

Angle of a leaning object

Photo shows a pendant in a car during driving in the right corner. From the picture define angle, for which is the pendant away from the vertical.

Inclined pendant in the car in the right corner

We take for correct the angles between o and o.

Next

Excellent! We can continue.

Next

Result of the measurement is incorrect. Try again.

Again

Result of the measurement is incorrect. The correct answer is .

Star card

Which constellation will ride exactly in the East on 5th of December at ?

Check

 
With star map you can cover many topics in astronomy.

Excellent, you are doing very well.

Next

It's true.

Next

The answer is not correct. Try again!

Again

On 5th of December at 19:00, exactly in the East, there will be rise of the Orion constellation.
