How would you describe a crescent moon? 1.) A crescent moon is when we can view more than half of the illuminated
side of the moon.

2.) A crescent moon is when we can view less than half of the illuminated
side of the moon.

3.) A crescent moon is when we can view all of the illuminated side of the
moon.

4.) A crescent moon is when we can view none of the illuminated side of the
moon.

Ogle–2013–blg–0723 is an exoplanet that is similar to earth in size and proximity to its star. this exoplanet has mass m=4.18×1024kg and radius r=5.66×106m. an astronaut whose weight on earth is w=735n lands on the planet. a. calculate m, the mass of the astronaut. b. calculate gp? , the acceleration due to gravity on the surface of ogle–2013–blg–0723. c. calculate wp? , the weight of the astronaut on the surface of ogle–2013–blg–0723. d. calculate v, the minimum velocity required to put an object into orbit above ogle–2013–blg–0723. e. calculate t, the time required to complete an orbit around ogle–2013–blg–0723.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
