Huh? The answer is A Shadow
Answer:
The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material.
Explanation:
The key idea behind the synthesis, processing and application of alloys consist in combining desire qualities from each mineral component in the form of a material. For example, steel is the combination of iron, which is ductile but prone to rusting in wet environments, and carbon, which offers high hardness and additional resistence to rusting in wet environments, but is fragile. Hence, steel is more resistant to rusting, ductile as iron and more resistant than iron.
Answer:
Vector Quantity
Explanation:
A Vector quantity is a quantity has both magnitude and direction while scalar quantity has only magnitude.
To determine the velocity of the ball falling, we need to use one kinematic equation which will allow as to calculate for the height of the skyscraper. This formula is expressed as:
y = v0t + at^2 / 2
v0 = 0 since it started at rest
a = g since it acts upon the gravitational force
t = 5 s
y = (9.81)(5)^2 / 2
y = 122.625 m
To obtain velocity we divide the height with time,
v = 122.625 / 5 = 24.53 m/s
closest would be option C.
