The speed of a bullet can be determined by using a device called a ballistic pendulum. The device is essentially a block of wood that hangs from two strings. When a bullet is fired at the block and it embeds itself and causes the combined block/bullet system to swing up to some height, h The mass of the block is 2.2 kg.

The bullet has a speed 530 m/s and a mass of 6.5 g.

Find the speed of the block/bullet system after collision.

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
