0.4 x 18 = 7.2 kg m/s
The momentum of the bottle after being hit is 0.2 x 25 = 5 kg m/s
7.2 - 5 = 2.2 kg m/s is the motmentum of the ball now
the velocity is 2.2/0.4 = 5.5 m/s
Answer:
1) henry moseley established a periodic table that arranges the elements by atomic number.
2) the atomic number increases from left to right on the periodic table.
3) metalloids have the characteristics of both metals and nonmetals.
Henry Gwyn Jeffreys Moseley (1887–1915) proposed that the number of positive nuclear charges (protons) in atom is equal to its atomic number in the periodic table.
Metalloids create a "staircase" down the periodic table.
For example, germanium (symbol: Ge) is a lustrous, hard, grayish-white metalloid in the carbon group.
Explanation:
In order to find out if the exponential function represents a growth or a decay, let's look at the number that is base to the exponent x.
If the number is greater than 1, so the function represents a growth, and if the number is less than 1, the function represents a decay.
Since the number is 1.075, the function represents a growth.
To find the % increase, first let's convert the number to percentage, and then subtract 100%:
So the percent increase is 7.5%.
After evaluating the equation, you should get a numerical value for the slope of the line such as slope, m = 1.13.
<h3>What is a graph?</h3>
A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
<h3>How to calculate the slope of a line?</h3>
Mathematically, the slope of a line can be calculated by using this formula;
Next, you should read the points on the x-axis and y-axis of your graph and then substitute them into formula for calculating the slope of a line.
After evaluating the equation, you should get a numerical value for the slope of the line such as slope, m = 1.13.
