A skyrocket firework burns fuel as it climbs. Its mass, m(h) kg, at height h m is given by (a) What is the mass of the rocket at h = 0 just before it is launched? (b) Show that the mass decreases as the rocket climbs. (c) Whatwork would be required to lift the rocket 10 m if its mass did not decrease? (d) Approximate the work done as the rocket goes from height h to h + Δh. (e) The rocket explodes at h = 250 m. Find total work done by the rocket from launch to explosion.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

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.

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
