Aguy puts a 500 gr glass100 g of water in the microwave. initially, both the glass and the water are at 300 k the guy falls asleep. the water will reach 100 c, evaporate and eventually trigger the explosion of the microwave, which has threshold power of 1200 w. estimate how long will take for the microwave to explode once it is activated with the glass with water inside

tube or goog with be a great resource to with that question

f=ma newton's second law 7x8=56n

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
