A construction worker Bob is standing at the top of a slanted rooftop when he accidentally drops an orange from his lunch bag. The orange rolls down the roof, which is angled at θ=30.3∘ relative to the horizontal as shown in the figure below. The bottom edge of the roof is 3.0 meters above the ground. If the orange leaves the right edge of the rooftop with a velocity of v_0 = 4.43 m/s , how far Δx to the right of the roof edge does his 1.8-meter tall fellow construction worker, Wendy, have to stand on the ground so that the orange just barely passes over her head?

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
