Explanation:
Let hockey puck is moving at constant speed v
so here we have
so time taken by the puck to strike the wall is given as
now time taken by sound to come back at the position of shooter is given as
so we know that total time is 1.9 s
now we have
Coronoid process of the ulna
Answer:
160J
Explanation:
Given force = 8N and total distance = 20 meters
Workdone = force x distance
= 8 x 20
= 160J
Therefore, workdone by Riley in pulling the hoover is 160J
The relationship between math and science is very complicated, yet at the same time very simple. In fact all scientific equations are expressed into some form of mathematical equations. Science is a body of knowledge about the Universe. Mathematics is a language that can describe relationships and change in relationships in a rational way. Science generally uses mathematics as a tool to describe science and vice versa.
