Question 1

Light diffracts when it enters a telescope. This causes the image to blur slightly. The amount of diffraction depends on the diameter of the hole through which the light enters the telescope and the wavelength of the light.
Which combination for diameter and wavelength will result in the sharpest image (least blurring)?

Answer 1

Large diameter and short wavelength

Question 2

What quantity does an ammeter measure in a circuit specifically?

Answer 2

Charges passing each point in the circuit per unit time.

Question 3

What is the relationship between light and resistance in an LDR?

Answer 3

Inversely proportional relationship.
As light increases, the resistance decreases. So if in a potential divider, it will get a lesser portion of the voltage.

Question 4

What is the relationship between temperature and resistance in the thermistor?

Answer 4

Inversely proportional.
As temperature increases, the resistance decreases. So if in a potential divider, it will get a lesser portion of the voltage.

Question 5

What happens to the mass of nuclides after fission and fusion?

Answer 5

They reduce.
