infiltration and evaporation
Answer:
D
Explanation:
The color you see is the color the object reflectes. The rest of the color are absorbed by that object.

Answer:
The ball will return to the thrower's hand with a speed of 10 m/s
Explanation:
- what is straight upward motion?
It is the motion when an object is projected upward, it moves in the opposite direction of the force of gravity.
The velocity is negative while the object moves up and positive while it moves downward due to upward motion.
Here,
A ball is thrown straight upward, u = 10 m/s
final velocity since ball momentarily stops at highest point, v= 0 m/s
According to Newton's 3rd equation of motion:
where,
g = acceleration due to gravity = -9.8 m/s²
h = height
substituting the values,
2(-9.8)h = (0)² - (10)²
h = 100 / 19.6
h = 5.10 m/s
Now, we consider downward motion:
2gh = v² - u²
where,
g = 9.8 m/s²
h = height = 5.10 m
v = return velocity of ball
u = 0 m/s
substituting the values,
2(9.8)(5.10 m) = V² - (0)²
V = √(99.96)
V = 9.99 m/s
V ≈ 10 m/s
Hence,
the ball will return to the thrower's hand with a speed of 10 m/s

You are unable to lift an object.
The Weight makes the object difficult to lift.
<h3>How can we state the above statement?</h3>
To calculate weight, we know from the formula that,
W=mg
Here in the formula,
w= the weight of the object.
m= mass of the object.
g= the acceleration due to gravity.
Also this is defined as force which acting on a object due to gravity. This kind of force usually it acts downwards.
This type of force has to overcome for it to be lifted up by individuals which is why Weight makes the object difficult to lift.
Now from the above discussion we can easily state that, The Weight is the property that makes the object difficult to lift.
