(1) The skull consists of twenty-two bones.
Longitudinal wave hope this is right :))))))))))
Answer:
210,600πft-lb
Explanation:
Force is a function F(x) of position x then in moving from
x = a to x= b
Work done =
Consider a water tank conical in shape
we will make small horizontal section of the water at depth h and thickness dh and also assume radius at depth h is w
we will have ,
weight of slice under construction
weight = volume × density × gravitational constant
Now we can find work done
=
= 210,600πft-lb

4) The lost value is $4500.
5) The values in a $ are Dependent variable in the graph.
6) Time(year) is inversely proportional to the values in $.
<u>
Explanation:
</u>
4) To calculate a loss between 2005 and 2006 we will find the value on the y-axis for 2005(which is on the x-axis) from the graph and subtract it by the value on the y-axis for 2006(which is on the x-axis) from the graph.
loss between 2005 and 2006 = $14500-$10000
= $4500
Percentage of loss is 31.03%
5) A dependent variable is a variable being tried and estimated in a logical test. The dependent variable in the graph is the value of the car that is given in the Dollar($). We can see that by the increase of the time there is an effect on the value of the car and the dependent variables are taken on the y-axis.
6) From the graph, It is shown that with an increase in time(year) the value of Sarah's car decreases and with the decrease in time its value increases. So it is clear that time is inversely proportional to the value of the car. By every passing year, the value of the car decreases.
Answer:
The velocity of ball and man after catching ball is
Explanation:
Since there is no friction and no external force the momentum is conserved .
Here when man catches ball then man and ball move with common velocity .
Let the final common velocity be ,
Given that mass of the ball is =
Given that mass of man is
Initial velocity of ball =
Now considering momentum conservation
