Is it true that work output of a machine is always less than work input because of energy lost due to friction?
Yes, it is true. Due to factors such as friction, heat generation, and other inefficiencies in the machine, some of the input energy is always lost to the surroundings rather than being converted into useful work output, resulting in the work output being less than the work input.
If the output force is less than the input force of a simple machine the mechanical advantage is less than one.?

A faster-moving fluid exerts less pressure than a slower-moving fluid true or false?
False. According to Bernoulli's principle, faster-moving fluids exert less pressure compared to slower-moving fluids. This is because faster-moving fluids have lower internal energy and therefore exert less pressure.
Is it true that a ship is able to float on water because its density is less than that of the water?
Yes, that's correct. A ship floats on water because it displaces an amount of water equal to its weight. The density of the ship (mass divided by volume) is less than that of water, allowing it to float.
What is the true about an object that floats in water?
An object that floats in water is less dense than the water it displaces. This means that the weight of the water it displaces is greater than the weight of the object itself, causing it to float. Objects that float have a density less than 1 g/cm3.
Is 10 yards less than 360 inches?
1 yard = 3 feet1 foot = 12 inchso, 1 yard = 36 inchesthen 10 yards = 360 inchesAccordingly;10 yards and 360 inches are equalso, the answer is:No, they are the same. 10 yards is equal to 360 inches.

What is the true of all deserts?
