Remember that weight is calculated as mass * gravity
Explanation:
Weight is the result of the influence of gravity on the mass of an object. Therefore, differences in gravity will cause an object of the same mass to weight differently on a scale. On the moon, an astronaut would weight 1/3 of their weight on earth. This is because the gravity on the moon is approximately 1/3 that on earth. The influence of gravity is also higher the larger the mass of an object.

Based on the clumping that was obtained when anti-D serum was dropped into John Doe's blood, John Doe's blood type is<u> Blood type D.</u>
<h3>What is blood typing?</h3>
Blood typing refers to the process by which blood is classified into types.
The process of typing blood involves reactions in which agglutination of blood occurs when a certain type of antiserum is dropped into the blood that contains a particular antigen such that an antibody-antigen pair is obtained.
The presence of certain antigens on the surface of blood helps to classify blood into types.
For example, when anti-A serum is added to a blood sample and agglutination occurs, the blood type could be either blood type A or blood type AB as these blood samples contain the A antigen on the surface of the red blood cells.
Similarly, when anti-D serum is added to a blood sample, the blood type is a blood group D as this blood sample contains the D antigen on the surface of the red blood cells.
