Complete Question:
Which technology is set up on the marketing team's phones?
a) Bluetooth
b) Tethering
c) NFC
d) Hotspot
Answer:
NFC
Explanation:
Near Field Communication (NFC) is a short-range wireless connectivity standard that uses magnetic field induction to enable communication between devices when brought within a few centimetres from each other. NFC offers a secured communication between connected electronic devices with simple setup that can be used to bootstrap more-capable wireless connections. It only covers a range of 10 cm to 20 cm.
None of the other options can transmit or share information for payments among the team except the NFC. NFC is also suitable for this setup because only a small range is expected to be covered.
Answer:
31.28m/s
Explanation:
We can use the third key equation of accelerated motion
Δd = viΔt+1/2aΔt^2
subtitute in the values we know
41.6 = vi(1.89)+1/2(-9.8)(1.89)^2
41.6 = vi(1.89) - 17.52
59.12 = vi(1.89)
vi = 31.28
I believe it's magnetic stripping. I hope that helps
If he's traveling at 5.2 m/s, then he covers
5.2 meters in the 1st second
5.2 meters in the 2nd second
5.2 meters in the 3rd second
5.2 meters in the 4th second

.
5.2 meters in the 14th second, and
5.2 meters in the 15th second.
He covers 5.2 meters 15 times in 15 seconds.
To find the total distance, you could write down 5.2 meters
15 times and add them all up. Or you could use the newly-
discovered, labor-saving process called 'multiplication' to do
the same thing. With multiplication, it can be done in one line:
(5.2 m/s) x (15 sec) = 78 meters .
