Two students are investigating the relationship between net force and acceleration on an object. They tie a string to a 1-kg blo
ck resting on a horizontal table. The string is run over a pulley and attached to a 100-gram weight hanging above the floor. The acceleration of the block is then calculated as the block falls to the floor. Which statement would best describe the greatest source of error in this investigation and suggest a reasonable method to reduce this error?
A) The block would have friction and a dynamic cart could be used.
B) The block on the table has too much mass and should be increased
C) The falling mass is too small to accelerate the block and should be increased.
D) A pulley has friction and the hanging mass should be replace with a spring scale.r
Inheritance of Traits by Offspring Follows Predictable Rules. Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.
Well I won't go to tooooooo much of that detail but the thing is FACT BY ME that everything around u is science and when u learn about ur surroundings it is science...!!!!
