Which two of the following reduce the background noise in magneto- medicine?

horrorfan [7]

Answer:

The answer is b.) and d.)

Explanation:

The options to reduce the background noise in magneto-medicine are given as follows:

a.) Orienting the heart parallel to the Earth's field

- This will have no significant effect on the measurements.

b.) Taking the difference of two nearby sensor measurements (gradiometer).

-This answer is TRUE.

c.) Placing the heart in a perpendicular fashion to the Earth's magnetic field.

_ This answer also will not have any significant effect on measurements.

d.) Using physical means to shield environmental fields.

- This answer is TRUE.

The force required to drag several objects across a floor was measured. Calculate the µK for these objects.

olganol [36]

Answer:

Explanation:

Case-A

Block weight $W=150\ lb$

Friction Force $f=30\ lb$

and friction force is

$f=\mu _kN$

where N=normal reaction (Usually equals to weight)

$\mu _k=\frac{30}{150}$

$\mu _K=\frac{1}{5}=0.2$

Case-B

Block weight $W=20\ N$

Friction Force $f=5\ N$

$\mu _k=\frac{f}{N}$

$\mu _k=\frac{5}{20}=\frac{1}{4}$

$\mu _k=0.25$

Case-C

Block weight $W=1500\ lb$

Friction Force $f=60\ lb$

$\mu _k=\frac{f}{N}$

$\mu _k=\frac{60}{1500}$

$\mu _k=0.04$

A rookie quarterback throws a football with an initial upward velocity component of 17.0 m/s and a horizontal velocity component

vitfil [10]

Answer:

(a) 1.73 s

(b) 14.75 m

(d) double

(e) 63.32 m

Explanation:

Vertical component of initial velocity, uy = 17 m/s

Horizontal component of initial velocity, ux = 18.3 m/s

(A) At highest point of trajectory, the vertical component of velocity is zero. Let the time taken is t.

Use first equation of motion in vertical direction

vy = uy - gt

0 = 17 - 9.8 t

t = 1.73 seconds

(B) Let the highest point is at height h.

Use III equation of motion in vertical direction

$v^{2}=u^{2}-2gh$

0 = 17 x 17 - 2 x 9.8 x h

h = 14.75 m

Use second equation of motion i vertical direction.

$h = ut + 0.5at^2$

h = 0 , u = 17 m/s

0 = 17 t - 0.5 x 9.8 t^2

t = 3.46 second

(D) It is the double of time calculated in part A

(E) Horizontal distance = horizontal velocity x total time

d = 18.3 x 3.46 = 63.32 m
