Vanilla cake,


My 2 cents…
15 is definitely 2
20 - option A cannot be right, If i want to see clearly , i would use a black board not white for the screen.
so by elimination , 4 is the answer

Lets wait for the experts to comments

Hi VC


Good Morning.

For Q23, I agree with your answer.

For Q29, option (3) is correct.
Weight refers to the gravitational force acting on an object. The greater the mass, the greater the gravitational force will be acting on it.

Best wishes
