How is the bike in the picture a system and how is the Earth a system?
JulijaS [17]

Answer:

The earth is a vast, complex system powered by two sources of energy: an internal source (the decay of radioactive elements in the geosphere, which generates geothermal heat) and an external source (the solar radiation received from the Sun); the vast majority of the energy in the earth system comes from the Sun.

A turtle swimming in a straight line toward shore has a speed of 0.50 m/sec. After 4.0 seconds, its speed is at 0.90 m/sec. What
PIT_PIT [208]

Answer:

0.1m/s²

Explanation:

Using the equation of motion

V = u+at

V is the final speed = 0.9m/s

Initial speed u = 0.5m/s

Time = 4secs

Get the acceleration

0.9 = 0 5+4a

0.9-0.5 = 4a

0.4 = 4a

a = 0.4/4

a = 0.1m/s²

Hence the acceleration is 0.1m/s²

c.) Compute the estimated theoretical maximum delay that can be generated if a microcontroller runs at 48Mhz and it takes three
Lisa [10]

Answer:

 

T1 = 1/12  x 48 MHz = 4 MHz

Timer’s clock period:

The time delay of one machine cycle is given below. We use this to generate the delay.

T2= 1/ 4000000= 0.25 µ sec

For delay of 10 ms:

1. Firstly divide the desired time delay value (10 ms) by the timer clock period.

N=  1 / 0.25µs

N= 10 ms / 0.25µsec

N=40000

2. Subtract the value of N from the maximum number of counts possible for 16 bit timer i.e. 2^16 = 65536.

M=65536-N

M=65536-40,000

M= 25536
