Answer:

Initial Velocity= 49 m/s

Time period= 5 secs

Explanation:

THIS IS THE COMPLETE QUESTION BELOW

A rocket shoots up 123 meters. What is it initial velocity?How long is it ascending

The initial velocity can be calculated using the expression below

u= √( 2gh)

Where g= Acceleration due to gravity= 98 m/s^2

h= height

Substitute the values we have

u = √(2*9.8*123)

u=√( 2410.8)

u = 49 m/s

the time period can be calculated as

(49/9.8)

= 5 sec

Hence time period is 5 secs

Answer:

Mode Name: BS-485 Half Duplex Mode 2 wires

Reason 1: less Noisy

Reason 2: Allows upto 32 receivers

Explanation:

The BS-485 is an electrical interface, that supports half-duplex mode through 2 wires, and full-duplex mode through four wires. However, here, we only need the half-duplex mode, and that is enough as the recordings are to be shown on the screen, which is the receivers, and they do not need to talk to the transmitter, while the transmitter is transmitting the recordings to the screen. And since, BS-485 supports around 32 receivers, its more than enough for this question requirement. So its half-duplex mode, and an example of the Serial data transmission. And also, it's synchronous, as there is no stop in between the data packets.
