Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg
The diagram which shows the parallelogram method for vector addition is shown in the image attached below.
In this scenario, let the two (2) vectors representing the two (2) adjacent sides of a parallelogram in both magnitude and direction drawn from a common point be:
The parallelogram law of vector addition states that if two (2) vectors 
and 
represent the two (2) adjacent sides of a parallelogram in both magnitude and direction drawn from a common point, then their sum 
or resultant vector (
) is equal to the diagonal of the parallelogram passing through that point in both magnitude and direction.
Therefore, the diagram which shows the parallelogram method for vector addition is shown in the image attached below.

A person who is physiologically dependent on a drug will experience freedom from the constant use of the drug upon cessation of use.
<h3>What is physiological dependent?</h3>
Physiological dependent occurs when an individual cannot do without the use of certain drugs.
The use of the drug can affect health, relational attitude and social duties. It often results into abuse of drugs and withdrawal from the use leads to freedom of the individual.
Therefore, A person who is physiologically dependent on a drug will experience freedom from the constant use of the drug upon cessation of use.
