Explanation:
a. time of flight =(2usinθ)/(g/6)
= 12usinθ/g
= (12x25xsin(30))/g
<h3>
= 15.306 seconds
</h3>
b. Range = u2sin(2θ)/(g/6)
= 6u2sin(2θ)/g
= (6x252xsin(60)) /9.8
= 331.387 metres
c. Range on earth = Range on moon/6 = 55.23 metres
On moon it travels 331.387 - 55.23 = 276.155 metres more than on earth
The different versions of an element have different isotopes, like Copper-63 and Carbon-65. The average of these two is not 64, because there are more Carbon-63 in the world than Carbon-65, 69.17% Copper-63 and 30.83% Copper-65, to be exact. By multiplying the atomic mass per unit of each one times their respective abundance in the world turned into a decimal, and adding these two products together, you het the atomic mass overall, which is 63.55
A plane mirror always forms a virtual image. the image and the object are the same distance from a flat mirror, the image size is the same as the object, and the image is upright!
When multiple forces are at work on an object, the net force is called a <em>resultant</em>, because it's a sum of vectors, and a sum of vectors is called their resultant.
