C, N and O all belong to the same period, in which it's 2nd Period.
Answer:
none
Explanation:
Newton's first law says an object in motion will stay in motion at the same speed and direction unless acted upon by some force.
No force is necessary for the object to keep its speed and direction on a frictionless surface.
Answer:
12.24 m/s
Explanation:
Speed: This can be defined as the rate of change of distance with time. The S.I unit of speed is m/s.
Using the formula,
a = v/t................ Equation 1
Where a = acceleration of the sprinter, v = speed of the sprinter, t = time.
making v the subject of the equation,
v = at ................. Equation 2
Given: a = 5.1 m/s², t = 2.4 s.
Substitute into equation 2
v = 5.1(2.4)
v = 12.24 m/s.
Hence, the speed of the sprinter = 12.24 m/s
A. The time it takes for the water to boil.
because that is what you are testing
Circle graph is the type of graph which most clearly shows the part or percentage related to the whole.
<u>Explanation:</u>
Graphs are the easiest tool to show the change in a given dependent variable with respect to independent variable. The influence or the effects will be seen in the graphs.
There are different kinds of graph like circle graph, bar graph, line graph. Each of these have their own method of showing the change in the dependent variable. Among them, circle graph is the one which will help to show the percentage of each variable related to the whole.
