The half-life of a certain material is 0.002 second. approximately how much of a 14-gram sample will be left after 0.004 second? a. 12 grams b. 3.5 grams c. 0.06 gram d. 7 grams

B. 3.5 grams.

Step-by-step explanation:

After 0.002 seconds  1/2 * 14 = 7 grams will be left.

After another 0.002 seconds ( total 0.004 seconds), 1/2 * 7 = 3.5 grams will be left.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
