The area of the tympanic membrane is 100 mm 2 and the area of the oval window is 5 mm 2 . if a sound wave applies 10 n to the ty

Flura [38]

<span>The answer is "0.5N".

According to the question;
P1=P2
so,
F1/A1= F2/A2

P=(F/A)

A1=100mm</span>²

F2= ?

F2= ((F1 x A2)/A1)
= ((10 x 5) /100)

=50/100

If the rifle is stopped by the hunter's shoulder in a distance of 3.23 cm, what is the magnitude of the average force exerted on

never [62]

By conservation of momentum, the initial recoil speed of the rifle is:
u = 904kg * 0.0106 kg / 3.53 kg = 2.7146 m/s

The final recoil speed v is zero in a distance of d = 0.0346 m

So the rifle's acceleration is a = (0 - u^2) / 2*d = -2.7146^2 / 2*.0323 m/s^2
a = -114.07m/s^2

Which of the following statements concerning the nuclear force is false? O The nuclear force is attractive and not repulsive. O

Ulleksa [173]

Answer:

The nuclear force is attractive and not repulsive.
The nuclear force is very weak and much smaller in relative magnitude than the electrostatic and gravitational forces.

Explanation:

Nuclear force is the strongest existing force in the nature.

It has the shortest range.

Its main function is to hold the subatomic particles together in nature.

The nuclear force is created by the exchange of pi mesons between the nucleons of an atom, but for this exchange to happen the particles must be close to one another of the order of few femtometer.

At about 1 femtometer the nuclear force is very strongly attractive in nature but at distance greater than 2.5 femtometer it fades away.

The force becomes repulsive in nature at distance less than 0.7 femtometer.
This force holds the likely charged protons together in the nucleus.

The momentum of a neutron p = 586.25 kg m / s.

<u>Explanation:</u>

The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.

Given mass m = 1.675 $\times$ 10, velocity v = 3.500 $\times$ 10

Momentum, p = mv

where m represents the mass,

v represents the velocity.

momentum p = (1.675 $\times$ 10) $\times$ (3.500 $\times$ 10)

momentum p = 586.25 kg m / s.
