Sliding friction is _ than the static friction.

Physics
1 answer:
Alona [7]3 years ago
4 0

Answer:

less

Explanation:

Sliding friction is always less than static friction. This is because in sliding friction, the bodies slide with each other and thus the effect of friction is not more. However, it does not happen in the case of static friction.

The figure shows a water-filled syringe with a 4.0-cm-long needle. What is the gauge pressure of the water at the point P, where
mars1129 [50]

Answer:

Pressure at P point is given as

P_p = 1.042 \times 10^5 Pa

Explanation:

As we know by poiseuille's equation of viscous flow of liquid through cylindrical pipe

Q = \frac{\Delta P \pi r^4}{8\eta L}

here we know that

L = 4 cm

\eta = 1 \times 10^{-3} Pa s

r = 1 mm

Q = flow rate

\pi r^2 v = \frac{\Delta P \pi r^4}{8\eta L}

v = \frac{\Delta P r^2}{8 \eta L}

10 = \frac{\Delta P (10^{-3})^2}{8(1 \times 10^[-3})(0.04)}

3.2 \times 10^{-3} = \Delta P (10^{-6})

\Delta P = 3.2 \times 10^3 Pa

now we have

P_p - P_{atm} = 3.2 \times 10^3

P_p = 1.01 \times 10^5 + 3.2 \times 10^3

P_p = 1.042 \times 10^5 Pa

Eardrum vibrations are transmitted to the cochlea by a piston consisting of
Lena [83]

Answer:

ossicles (comprising of hammer, anvil, and stirrup)

Explanation:

The hammer, anvil and stirrup are also known as the malleus, incus, and stapes, respectively which are the part of the middle ear.

They transmit the sound vibrations from eardrum to cochlea by a level mechanism. The generate mechanical advantage by multiplying the force over a shorter distance from the input of a smaller force at a larger distance.

ANSWER ASAP!!!If a wave machine produces 10 waves in 2 seconds, what is the frequency of the machine in Hertz?
Rufina [12.5K]

Answer:

5Hz

Explanation:

Frequency = No. of waves per second

10 waves are produced in 2 seconds

in one second 10/2 waves are produced

(ie) 5 waves are produced in 1 second

Therefore the frequency of wave is 5 Hz

How do you convert from picoseconds to milliseconds using the conversion factors?
andrew11 [14]

There are 10⁹ picoseconds in 1 Ms

1 picosecond= 10¹² s

1 Ms = 10⁻³ s

so the number of picoseconds in one Ms=(10⁻³ s/1 Ms) * (10¹² Ps/ 1 s)=10⁹

Thus there are 10⁹ picoseconds in 1 Ms
