To show motion on a graph you draw the path of where the object has gone
Answer:
24.084 m/s
Explanation:
From the law of conservation of linear momentum
Total momentum before collision equals to the total momentum after collision
Since momentum=mv where m is mass and v is velocity
where is the mass of the truck, is velocity of the truck, is the common velocity of moving and standing truck after collision and is the mass of the standing truck
Making the subject we obtain
Substituting as 25000 Kg, as 22.3 m/s, as 2000 Kg we obtain
Therefore, assuming no friction and considering that after collision they still move eastwards hence common velocity and initial truck velocities are positive
The truck was moving at 24.084 m/s
1.) Its a controlled experiment because both groups A and B get the equal mount of sunlight and water. The manipulated variable would be the fertilizer.
2.) Because a theory must consists of more than experiment before it can actually be considered a theory. It must be performed multiple times.
3.) Because if the growth was on the B spot, the graph would be a bar graph because the growth would still increase by each day.
Sound waves are transmitted through solids, liquids, and gases. Light waves are transmitted through transparent materials (may be clear or colored material such as filters) that allow most of the light that strikes them to pass through them. Only a small amount of light is reflected or absorbed.
The direction of spontaneous heat flow in a system is described by the second law of thermodynamics, which describes that the direction of spontaneous heat flow is from a region of higher heat energy to a region of lower heat energy.
Multiple statements of this law are available, such as the one presented by Carnot or the one presented by Clausius and Planck.
