The answer to your question is A.
Answer:
A
Explanation:
The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
Answer:
475
Explanation:
Cori does not exert any more force than 475 J, so 475 is the answer.
Sliding: when an object slides across a surface
rolling: when an object rolls across a surface
static is when something ain't moving
Physical and chemical laboratory experiments include three primary sources of error: systematic error, random error and human error. this simulation shows systematic error.
Systematic error applies to repeated measuring of the same object under repeated conditions of measurement. The amount of the error value is either positive or negative; which is called the fixed system error in laboratory experiments and laboratory tests.
Human error in laboratory experiments and lab tests primarily refers to the mistake in physical and chemical inspection phase caused by the factors of the inspector.
Random error is error caused by unknown factors. This error poses erratic changes at random, primarily due to a variety of small, independent, and accidental factors. The random error is atypical from the surface.
