Increase because the mass of an object aligns with its weight
all engines operate at less than 100 percent efficiency because they EMIT heat. ;)
Answer:
8.37 Joules
Explanation:
The amount of energy that a substance, such as animal tissue or rubber can take and yet return to its original condition is known as resilience. When we stress such a substance and then let it restore to its previous state, we are referring to the substance to maintain its elastic area of the stress-strain curve.
From the given information:
the resilence is 0.93
The amount of work done during stretching of the tendon = 9.00 J
Thus,
the work done when relaxing = 0.93 × 9.00 J
= 8.37 Joules
Current(I) = Voltage/Resistance
= 42/(10+ 4)
= 42/14
Current = 3 A
Answer:
Explanation:
Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, 
where, “m" mass of an object and "v" is volume of an object.
Given that,
Dimensions of the block are 20 cm, 5 cm and 10 cm.
Mass of the block is 2700 g.
Substitute the given values in to find density of a block.
