The greater the cross-sectional area of an object, the greater the amount of air resistance it encounters since it collides with more air molecules. ... It will have to accelerate for a longer period of time before there is enough upward air resistance to balance the downward force of gravity.
The force of gravity between two objects is given by:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is their separation
In this problem, the mass of the object is
, while the Earth's mass is
. Their separation is
, therefore the gravitational force exerted on the object is
They have similar physical and chemical properties because of thier valence electrons
Answer:
They would land at the same time
Explanation:
They would land at the same exact time.
As weird, impossible and unbelievable as it appears. When in a vacuum, every weight, body and material when released from the same height would land on the ground at the same time. This also means that like in the question, a feather and a ball would land at the same time. And just for illustrations as well, a feather and a car would land at the same time as well.
Answer:
Pseudoscience
Explanation:
Predicting future events in a person's life based on the lines on the palm of the hand is an example of Pseudoscience. A pseudoscience is a false science that makes claims based on faulty or nonexistent scientific evidence and often characterized by contradictory, excessive claims, etc. These types of Pseudoscientific beliefs are common due to widespread "scientific illiteracy among different societies.
