Vector trigonometry can be used for this problem. Since the horizontal component is 12 meters per second, this is technically the hypotenuse (actual initial velocity) multiplied to cosine of 40 degrees. Therefore, to find the hypotenuse, we must divide 12 by cosine 40degrees. cos(40)= 0.766, and 12/0.766 = approximately 15.664, therefore our answer is (3) 15.7 m/s
Answer:
they store information
Explanation:
Information are encoded on the magnetic part of a hard drive and the strip of a credit card.
- On the drive, series of magnetic fields are used to encode information.
- The data is stored in form of zeros and ones.
- A credit card has a magnetic strip where information is encoded.
- The stripe provides a readability function for electronic devices.
Answer:
A pure substance has only one substance while a mixture has two or more substances
Explanation:
Answer:
10 seconds
Explanation:
We have the equation V = at (speed = acceleration x time)
We want to find the time, so can rearrange to T = V/a (time = speed / acceleration).
From the question, we know V is 5 and a is 0.5.
Now we can substitute that into our equation: 5/0.5 = 10.
So the time is 10 seconds.
Hope this helps! Let me know if you have any questions :)
