What is the resolution of an analog-to-digital converter with a word length of 12 bits and an analogue signal input range of 100
Elena L [17]

Answer:

The resolution of an analog-to-digital converter is 24.41 mV

Explanation:

Resolution of an analog-to-digital  = (analogue signal input range)/2ⁿ

where;

n is the number or length of bit, and in this question it is given as 12

Also, the analogue signal input range is 100V

Resolution of an analog-to-digital  = 100V/2¹²

2¹² = 4096

Resolution of an analog-to-digital  = 100V/4096

Resolution of an analog-to-digital  = 0.02441 V = 24.41 mV

Therefore, the resolution of an analog-to-digital converter is 24.41 mV

maxonik [38]

Answer:

a = -0.4m/s²

Explanation:

v_f = v_I + (a)(t)

a(t) = v_f-v_I

a = (v_f-v_I)/t

a = (0m/s-12m/s)/30s

a = -0.4m/s²

A car with a momentum of 3,200 kg-m/s moves foward at a rate of 2 m/s. What is the mass of the vehicle?
natulia [17]

Answer:

1600 kg

Explanation:

use the formula p=mv. p=3200, v=2. Plug in and rearrange.

3200=(m)(2)

m= 3200/2

m=1600

GREYUIT [131]

Free fall without air resistance:

g=9.81 m/s²

t=235 s

h=?

h=0.5*g*t²

h=0.5*9.81*235²

h=270879m =270 km
