and i need good suggestions for physics ..it should be easy and get me a good grade..

Answer 1

you can do an experiment where you ban boil water in a paper bowl.trust me its possible .i have done it n won prizes at school.make a paper bowl,fill 3/4th water n keep a candle underneath.paper doesn burn because water from above cools it and it doesn become wet n soak either because the candle heats off the water.

Answer 2

i'm in 9th too! i can help u

u can make a lie detector.

It consists of three transistors (TR1 to TR3), a capacitor (C1), two lights or LEDs (L1 & L2), five resistors (R1 to R5), and a variable resistor (VR1).

This circuit is based on the fact that a person's skin resistance changes when they sweat (sweating because they're lying). Dry skin has a resistance of about 1 million ohms, whereas the resistance of moist skin is reduced by a factor of ten or more.

search for the circuit diagram & start making it.

Answer 3

I think that You should make solar cooker
