Science

Question 1

What is a longitudinal wave?

Answer 1

Longitudinal waves cause the medium to move parallel to the direction of the wave.

Question 2

What is a transverse wave?

Answer 2

Transverse waves cause the matter to move perpendicular to the direction of the wave.

Question 3

Answer 3

Energy is neither created nor destroyed.

Question 4

How do you calculate GPE?

Answer 4

Mass X Gravity (9.8 on Earth) X Height

Question 5

How do you calculate KE?

Answer 5

1/2 Mass X Velocity (speed) squared.

Question 6

How does a flow diagram work?

Answer 6

You start with an initial amount of energy and then you branch off the losses and end with your initial amount minus your losses.

Question 7

What are the common components of an electric circuit?

Answer 7

Battery or Cell, Wire, Switch, Light.

Question 8

What is current?

Answer 8

Current is the flow of electric charge (usually electrons) through a conductor, like a wire. It’s measured in amperes (A).

Question 9

What is voltage?

Answer 9

Voltage, also known as electric potential difference, is the force that pushes the electric charge through a circuit. It’s measured in volts (V).

Question 10

What is resistance?

Answer 10

Resistance is the opposition that a material offers to the flow of electric current. It’s measured in ohms (Ω).

Question 11

What are the different types of circuits?

Answer 11

Series and parallel circuits.

Question 12

What are the different types of heat transfer?

Answer 12

Convection, Conduction and Radiation.

Question 13

What are the different measurements of a wave?

Answer 13

The crest is the top, the trough is the bottom, the wavelength is the distance between all of the crests and the amplitude is the distance between the crests and the middle of the wave.

Question 24

What is a circuit diagram?

Answer 24

A graphical representation of a circuit.

Question 25

Who created the third atom model, the name, what was it and the date created?

Answer 25

Ernest Rutherford's nuclear Model had a nucleus and was created in 1911.

Question 26

Who created the fourth atom model, the name, what was it and the date created?

Question 34

Who was Dmitri Mendeleev?

Answer 34

He was the designer of the periodic table.

Question 35

Why did Dmitri Mendeleev leave blank spaces in the periodic table?

Answer 35

To make space for undiscovered elements.

Question 36

What is Conduction?

Answer 36

Conduction is when you touch something hot and it transfers to your hand.

Question 37

What is Convection?

Answer 37

Convection is when cold air lowers because it is dense and hot water rises because it is less dense because of atoms moving.
