Aprojectile fired from the ground follows the trajectory given by the following equation, where vo is the initial speed, 0 is the angle of projection, g is the acceleration due to gravity, and k is the drag factor caused by air resistance. vo cos(8) using the power series representation in(1 +xx)-x + . < x < 1, verify that the trajectory can be rewritten as the following. using the power series representation ln(1 + x) = x--+ gx2 kgx3 2vo2 cos2(0) 3vo3 cos3(0) 4vo4 cos4(0) y (tan(0))x - y = ( tan(0) + w cos(0) n 1 y = -?
using the formula
gpe = m*g*h (mass (kg) * gravitational field strength (n/kg) * height (m) )
we can say that -
100 j = 0.5 * 9.8 * x
x = 100/(0.5 * 9.8)
x = 20.4 m
your answer is 20.4 m
it would be 2300000 grams.
answer : absorbs and releases thermal energy by first vaporizing then condensing.
the transfer of heat from one place to another is a function of refrigerant.
initially, the liquid refrigerant enters the indoor coil. here, it changes from liquid state to vapor state. then this vapor refrigerant enters into the compressor.
finally, it flows into the condenser. here, it releases heat to the outside air.
so, refrigerant absorbs and releases thermal energy by first vaporizing then condensing.
