Freya is investigating different types of insulators. She wraps different insulators around a metal can of hot water. At the start the water is at 90 °C. She measures the how long it takes for the temperature to reach 60 ° C.

State the type of energy transfer through the metal can
Material: Paper, Cotton, Foam, Wool
Time to drop to 60(seconds): 4,7,15,10
Please help im really stuc

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
