(repost because nobody answered my last one) physical science question what effects would happen to the air inside a soccer ball if its left outside in the sun, or left outside overnight? ? what would be a good hypothesis? a possible experiment for this? answer all 3 or at least 2 if you are going to answer, and be detailed, other than that it won't be any good!

Compare the horizontal displacement of the two balls as they travel to the ground. what do you observe?

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
