The moon’s period of revolution is 27 1/3 days, and its period of rotation about its axis is _____.

mestny [16]

It lasts 29 1/2 days.
-the sidereal month- is the true period of the moon's revolution around Earth. It lasts 27 1/3 days.
-the difference of 2 days between the synodic and sidereal cycles is due to the Earth- moon system also moving in an orbit around the sun.

A golfer tees off from the top of a rise, giving the golf ball an initial velocity of 44 m/s at an angle of 25° above the horizo

mars1129 [50]

Answer:

a) $y=17.6m$

b) $v_{x}=39.87m/s\\v_{y}=-28.05m/s$

Explanation:

From the exercise we got our <u>initial data</u>

$v_{o}=44m/s\\\beta =25\\x=190m$

a) To find <u><em>maximum height</em></u> we know that at that point $v_{y}=0$

$v_{y} ^{2} =v_{oy} ^{2} +2a(y-y_{o} )$

$0=(44sin25)^{2} -2(9.8)y$

Solving for y

$y=\frac{(44sin25)^{2} }{2(9.8)} =17.6 m/s$

b) Since we know that the ball strikes the fairway 190 m away

$x=v_{ox}t\\ 190=44cos25t$

Solving for t

$t=4.76s$

Now, we can calculate the speed of the ball in both axes

$v_{x}=44cos25=39.87m/s$

$v_{y}=v_{oy}+at$

$v_{y}=44sin25-(9.8)(4.76)=-28.05m/s$

The <em>negative</em> sign means the direction of the ball at that point.

A pan of ice is placed over a flame.

AveGali [126]

A. The molecules start packed together very tightly in a solid. Then when it turns to water, the molecules can move around each other freely, but still contained. When water turns to vapor, the molecules are going crazy moving around. They are not contained at all and bounce of of each other freely.

b. The temperature rises. (ice turns to water at 33 degrees and water turns to vapor at 212 degrees)
