College students signed up to be subjects in a psychology experiment. when they arrive, they are told that interviews are running late, and they are left in a waiting room. the experimenters have placed a cell phone in the room and the subjects are told not to answer the phone no matter how many times it rings. some subjects are in the room alone and others are in pairs; these are the treatments being compared. will the subject answer the phone? the students agreed to take part in an unspecified experiment, and the true nature of the experiment is explained to them afterward.
does this meet the requirement of informed consent? explain.

yes, because they agreed to participate in an experiment
yes, because they are not forced to answer the phone
no, because they had to wait for the interviews
no, because they did not know the nature of the experiment before participating
unable to determine whether subjects consented to experiment

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

3x + 4y -25 =0 represents the amount of change sianna should recieve

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
