First one heat, the second one is radiation and the third is radiated ;)
185 newtons because (W=Fd so W/d=F)296/1.6=185
Answer:
Explanation:
Let the distance from spotlight to wall be 15m, and distance from the man to the building be 
.
#Therefore the height of the shadow as a function of the above is 
Hence, height of the shadow is expressed as s=(15-x)m
#See attached photo for illustration
1). Calculate how long it takes an object to fall 4,000 m after it's dropped. (Use D = (1/2) (g) (T²) . D is 4,000 m. g = 9.8 m/s². Find T .)
2). Calculate how far the object will move HORIZONTALLY in that length of time, if it's moving at 75 m/s. (Distance = (75 m/s) x (time) . )
