Hey I’m just setting up my profile so I’ll say fast

More in details:

Our senses allow us to experience the world we live in, and are one of the key components of consciousness. ... This is why the study of our senses, or sensation, is considered to be such an important area of psychology, because it is one of the key components that makes consciousness possible.

HELP!

igor_vitrenko [27]

Answer:

1) Option D

2) Option D

3) Option C

Explanation:

1) Kinetic energy $=\frac{1}{2} mv^2$

m = 500 kg

v = 10 m/s

Kinetic energy $=\frac{1}{2} *500*10^2=25000 J$

Option D is the correct answer.

2) Potential energy = mgh

m = 25 kg

g = 10 m/s²

h = 42 m

Potential energy = 25 * 10 * 42 = 10500 J

Option D is the correct answer.

3) Thermal equilibrium means no heat flow from each other two systems, that is achieved when both systems have same temperature.

Option C is the correct answer.

2. Jenny picks up a guitar and strums. If the sound from the string emanates out at 440 Hz,

erik [133]

Answer:

6.8×10^6 m

Explanation:

f = velocity of light/ wavelength

440= 3×10^8 / wavelength

wavelength = 3×10^7/ 44

= 6.8×10^6 m

Immediately after being struck by a hammer, the nail (mass of 50 g) has a velocity of 50 m/s. The total frictional force is 62.5

Marina86 [1]

Answer:

nail will stop after traveling 1000 m

Explanation:

We have given mass m = 50 gram = 0.05 kg

Frictional force which is used to stop the mass F = 62.5 kN

Initial velocity is given u = 50 m/sec

From newton's law force is equal to F = ma, here m is mass and a is acceleration

So $a=\frac{F}{m}=\frac{62.5\times 10^3}{0.05}=1.25\times 10^6m/sec^2$

As finally nail stops so final velocity v = 0 m/sec

From third equation of motion $v^2=u^2+2as$

So $0^2=50^2-2\times 1.25\times 10^6\times s$

s = 1000 m

So nail will stop after traveling 1000 m
