Answer:

B. pinna . . . eardrum

Explanation:

Hearing is one unique feature of organisms performed by the EAR in humans and some other animals. The ear functions to transmit sound vibrations as impulses to the brain, which sends it back as sound. Specific part of the ear plays a pivotal role in bringing about the hearing process.

The external or visible part of the ear called PINNA channels or guide the sound waves coming from the external environment into the EARDRUM OR TYMPANIC MEMBRANE, which vibrates in response to the reception of the sound waves.

A potential difference of 12v produces a current of 0.30A in a piece of cooper wire. What is the resistance of the copper wire?
marysya [2.9K]

Well , its a easy problem  

By ohms law,  

we have V= IR  

Where V is the voltage applied across the wire and R is the resistance and I is the current  

=> R = V/I  

=> R = 12/0.3 = 40 ohm

A 2-kg wood block is pulled by a string across a rough horizontal floor. The string exerts a tension force of 30 N on the block
Luden [163]

Answer:

Work done, W = 84.57 Joules

Explanation:

It is given that,

Mass of the wooden block, m = 2 kg

Tension force acting on the string, F = 30 N

Angle made by the block with the horizontal, \theta=20^{\circ}

Distance covered by the block, d = 3 m

Let W is the work done by the tension force. It can be calculated as :

W=F\ cos\theta\times d

W=30\times cos(20)\times 3

W = 84.57 Joules

So, the work done by the tension force is 84.57 Joules. Hence, this is the required solution.

Speedy Sue, driving at 34.0 m/s, enters a one-lane tunnel. She then observes a slow-moving van 160 m ahead traveling at 5.40 m/s
emmasim [6.3K]

Answer:

Yes, there will be collision.

Explanation

Initial relative velocity u  = 34-5.4 = 28.6 m/s

required final relative velocity  v = 0

Acceleration , suppose be a .

Distance traveled =d = 160 m

Using the formula for relative motion,

v² - u² = 2as

0 - 28.6²=2as

a = - 2.55 m s⁻².

Since this required value is more than maximum  braking deceleration so , there will be collision.
