A cart pushing ten bricks or a cart pushing twenty bricks using the same force and going the same distance which has greater kinetic energy?
The same force could not be applied to travel the same distance if there is a larger mass in one instance. Applied force will accelerate a given mass twice as much as a mass half as large. If both are moving the same distance, the 20-brick cart had more kinetic energy when in motion.
What else can I help you with?
What has a greater mass 10000 grams of bricks or 10000 grams of feathers?
10000 grams of bricks have a greater mass than 10000 grams of feathers because bricks are denser and heavier than feathers. Weight depends on the mass and the force of gravity acting on an object, so in this case, both would weigh the same.
Why does the heavy bricks sinks into the water.give reasons?
Water is dense at about eight pounds a gallon. A brick is more dense and will sink. The weight of the water in the space taken up by the water that it displaces is less than the weight of the brick taking up that space so it drops to the bottom.
What change in kinetic energy does an airplane experience on takeoff if it is moved a distance of 500 m by a sustained netforce of 5000 N?
Tell you what: We'll calculate how much work is done by the force, not howmuch kinetic energy the plane picks up, and then we'll tell you why.The work done is (force) x (distance) = (5,000) x (500) = 2,500,000 joules.Whenever we do these force/distance/work/energy problems, we always ignorefriction, air resistance, etc. because it's just too hard and complicated to takeall of them into consideration, and it would only get in the way of understandingthe basic principles anyway.How valid is the answer we get when we ignore these things ? Well, it may be OK,and pretty close to reality, for baseballs, stones, bullets, and bricks. But it's definitelynot OK for airplanes. Airplanes are designed specifically to have an intimate relationshipwith the air, and that's the only reason they work at all.If you do 2.5 million joules of work on a baseball, a stone, or even a little red wagon,it may have close to 2.5 million joules of kinetic energy when you stop pushing. Butan airplane won't. It's designed to use some of that K.E. to move air, to generateLIFT, with the ultimate objective of getting off of the ground. That drains awaya big part of the work done to roll down the runway, and that's the big part thatwill never show up as kinetic energy.
How much work is done to lift 40kg of bricks to a height of 10m?
The work done to lift 40kg of bricks to a height of 10m can be calculated using the formula: Work = Force x Distance. The force required to lift the bricks is equal to the weight, which is mass x gravity (40kg x 9.8m/s^2). Plug these values into the formula to find the work done.
Why does bricks falls faster than cotton of equal masses?
That only happens when they fall through air. The reason is the friction of the respective bodies plowing through the amount of air that each is in contact with. In the absence of air, bricks and cotton would accelerate at the same rate, reach the same speed at the same time, and hit bottom together.
How do you separate bricks that have been glued with liquid nails?
To separate bricks that have been glued with Liquid Nails you will need Windshield Cut-Out wire. Begin pushing the wire between the bricks at one corner. Continue using the wire to separate the bricks.
How do you stop dog from barking and pushing Bricks all over yard?
Put all of the bricks away and tell your dog to stop barking by giving him a treat when he does stop barking.
Which has the greater mass a kilogram of feathers or kilogram of bricks?
Neither. A kilogram is the same regardless.
The solid brick shown is made of small bricks of side 1 When the large brick is disassembled into its component small bricks the total surface area of all the small bricks is how much greater than t?

What is more dense- a ton of bricks or a ton of feathers?
The answer is very much the same as the answer to the question: "Which weighs most, hot water, cold water, or water colored green ?" The answer, of course, is: That depends on how much you have of each substance. One thing we can definitely guarantee: A pound of bricks, a pound of cheese, and a pound of feathers all have precisely the same, identical, and indistinguishable weight.
What is the collective noun for bricks?
The collective noun for bricks is a course of bricks.
Which has a greater mass a kilogram of bricks or a kilogram of feathers?
They both have the same mass. A kilogram measure mass regardless of the material, volume etc.
What are LEGO bricks?
Lego bricks are little blocks and Lego bricks can connect to other Lego bricks
Are bricks flammable?
Bricks are not flammable, but coal bricks are. IF THERE IS A BETTER ANSWER, IMPROVE.
