The answer that best fits the blank provided above is MECHANICAL ADVANTAGE. Given that in simple machines, output should not be greater than the input therefore, the Mechanical advantage of a simple machine has its input forces multiplied instead which results in force amplification. The answer for this would be option A.
This is caused my a magic illusion and when you stand at a certain angle in themirror it changes your image
I think the answer would be C. because the orbit around the sun compared to the Earth's (Identifies the seasons change and the year) would be longer, but the day is unknown because that is where it would come down to the total mass of the planet and other important factors about the planets properties.
C.figure 3 is the answer had the same and got is right
Answer:
Explanation:
At the time of a body achieving terminal velocity, the drag force becomes equal to the weight of the body less the buoyant force by the surrounding medium which can be represented by the following equation
Where r is radius of the body , d is density of the material of the body σ is density of the medium and n is coefficient of viscosity of the medium and v is terminal velocity.
Simplifying
v =
Assuming the value of density of air as 1.225 kg/m³ and putting other given values in the formula we get
v = [/tex]
v = 387 x 10⁻⁵ m/s
Terminal velocity = 387 x 10⁻⁵ m/s
Time taken to fall a distance of 100 m
=
= 2.6 x 10⁴ s.
