Froghopper insects have a typical mass of around 12.5 mg and can jump to a height of 42.3 cm. the takeoff velocity is achieved as the insect flexes its legs over a distance of approximately 2.00 mm. assume that the jump is vertical and that the froghopper undergoes constant acceleration while its feet are in contact with the ground. ignore air resistance. what is the acceleration of the insect during the time of the jump (before it leaves the ground)?

Which of the following statements are true of solids? a.the particles do not vibrate. b.the particles are in a fixed location. c.they have strong intermolecular forces between the atoms or molecules. d.the particles have less kinetic energy than those of liquids or gases.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
