The wind gets trapped under the little lip of the roof and builds up so much pressure poof it’s blown away

Answer:

Roofs are blown down due to the speed and pressure of the winds that will become strong and can destroy anything in its path.

If we're talking about part c then

igneous rock + weathering and erosion = sedimentary rock

sedimentary rock + heat and pressure = metamorphic rock

magma + cooling = igneous rock

A 25-kg child sits at the top of a 4-meter slide. After sliding down, the child is traveling at 5 m/s. How much PE does he start

Semmy [17]

Daniddmelo says it right there, don't know why he got reported.

The potential energy (PE) is mass x height x gravity. So it would be 25 kg x 4 m x 9.8 = 980 joules. The child starts out with 980 joules of potential energy. The kinetic energy (KE) is (1/2) x mass x velocity squared. KE = (1/2) x 25 kg x 5 m/s2 = 312.5 joules. So he ends with 312.5 joules of kinetic energy. The Energy lost to friction = PE - KE. 980- 312.5 = 667.5 joules of energy lost to friction.

Please don't just copy and paste, and thank you Dan cause you practically did it I just... elaborated more? I dunno.
