Why a plastic tray float in water?
A plastic tray will float in water because the plastic material is less dense than water, causing it to displace an amount of water greater than its own weight. This buoyant force keeps the tray afloat on the water's surface.
You push a food tray 1.5m along a cafrteria table with a constant force of 18N How much work do you do?
The work done can be calculated using the formula: work = force x distance. Plugging in the values, we get work = 18N x 1.5m = 27J. Therefore, you do 27 Joules of work to push the food tray along the cafeteria table.
Why would an orange roll off your cafeteria tray if you stopped suddenly?
The orange would roll off your tray due to inertia, which is the tendency of an object to resist changes in its state of motion. When you stop suddenly, the orange wants to keep moving forward due to its momentum, causing it to roll off the tray.
What is the function of the measurement tray on a triple beam balance?

What should you do if you cannot eject the CD from an iMac G3?
It depends on which iMac G3 you have. With the tray loading (the tray pops out towards you) there is a small hole you have to stick a paper clip into. If you have a slot loading (you push the CD in and it ejects it by itself) there is a hole on the front right side of the drive that is supposed to force the CD out if you push a paperclip into it. Otherwise you will have to take the whole thing apart.

What forces act if you put a tray in water?
weight of tray put downward force while the surface tention of water apply up ward force
How come your CD slot wont open?
It could be that the drive has failed or that something is jammed. Straighten a paperclip then push the wire in the small hole that is just below the tray. That should release the locking mechanism and let you open the tray manually. Have the computer OFF when you do this.
If a student buys a lunch tray with a mass of 0.5kg and causes it to accelerate across the cafeteria at a rate of 15 miles per second squares then how much force did the student apply?
15 miles/sec2 = 24,140.16 meters/sec2F = M A = (0.5) (24,140.16) = 12,070.08 newtons.Notes:1). The acceleration given is roughly 2,460 G's. Both the lunch tray and the student's wrist are shattered.2). The force is roughly equivalent to 2,715 pounds. The student is a champion athlete, butwith a shattered wrist.3). The force must be applied to the lunch tray continuously in order to maintain the acceleration.The moment the speeding lunch tray leaves the student's grasp, acceleration ceases.4). Fortunately for the student, the force is not required for very long. If launched from rest, then at the givenrate of acceleration, the lunch tray covers the length of the school's football field in the first 0.0091 second.
