Kilo: a prefix used on metric units to indicate a multiple of 1000. For example 1kg = 1000 g
The kinetic energy of an object depends on two factors: mass(m) and velocity(v). The mass of an object can be measured in kilograms(kg) and velocity of the object in meters per second(m/s).
Answer:
Two significant figures
Step-by-step explanation:
In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.
2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)
There are three significant figures in 2.05, but only two in 32.
You must round to <em>two</em> significant figures and report the answer as 66 cm².
65.600 000 00 cm² ⟶ 66 cm²
Answer: Solid
Explanation: Solids are closely packed together so they can not be compressed and have a definite shape.
