80% Answer Correctly

electron

neutron

proton

Solution

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.


3

Which is the proper order of Earth's atmospheric layers from the surface up to space?

58% Answer Correctly

troposphere, stratosphere, mesosphere, thermosphere

thermosphere, mesosphere, stratosphere, troposphere

stratosphere, troposphere, mesosphere, thermosphere

mesosphere, thermosphere, stratosphere, troposphere


Solution

The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.


4

During digestion, the kidneys filter substances from the blood. Which of the following is not filtered by the kidneys?

minerals

fats

salt

water


Solution

Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.


5

The formula  \(\vec{F_{g}} = { Gm_{1}m_{2} \over r^2}\) applies to which of Newton's laws?

66% Answer Correctly

first law of motion

third law of motion

second law of motion

universal gravitation


Solution

Newton's law of universal gravitation defines gravity: All objects in the universe attract each other with an equal force that varies directly as a product of their masses, and inversely as a square of their distance from each other. Expressed as a formula:  \(\vec{F_{g}} = { Gm_{1}m_{2} \over r^2}\) where r is the distance between the two objects and G is the gravitational constant with a value of 6.67 x 10-11.
