Marcus tells Sabrina that for the last few months, he has not been able to detect moderate heat or cold with his fingertips. Whi

hram777 [196]

Answer: The free ending nerves.

Explanation:

At our fingertips, we have a lot of sensory nerve endings, that give information about changes that occur at your skin.

Like touching something with a given texture, feeling pain, or noticing changes in temperature.

There are different types of nerve endings, particularly the ones responsible to detect pain, and temperature are the free nerve endings.

So Marcus may have the free nerve endings damaged.

A slender rod is 80.0 cm long and has mass 0.390 kg . A small 0.0200-kg sphere is welded to one end of the rod, and a small 0.05

Keith_Richards [23]

Answer

given,

length of slender rod =80 cm = 0.8 m

mass of rod = 0.39 Kg

mass of small sphere = 0.0200 kg

mass of another sphere weld = 0.0500 Kg

calculating the moment of inertia of the system

$I = \dfrac{ML^2}{12}+\dfrac{m_1L^2}{4}+\dfrac{mL^2}{4}$

$I = \dfrac{0.39\times 0.8^2}{12}+\dfrac{0.02\times 0.8^2}{4}+\dfrac{0.05\times 0.8^2}{4}$

$I =0.032\ kg.m^2$

using conservation of energy

$\dfrac{1}{2}I\omega^2 = (m_1-m_2)g\dfrac{L}{2}$

$\omega=\sqrt{\dfrac{(m_1-m_2)gL}{I}}$

$\omega=\sqrt{\dfrac{(0.05-0.02)\times 9.8 \times 0.8}{0.032}}$

$\omega=2.71 \rad/s$

we know,

v = r ω

$v = \dfrac{L}{2} \times 2.71$

$v = \dfrac{0.8}{2} \times 2.71$

v = 1.084 m/s

Una pelota recorre 20 m hacia la derecha y luego 10 m hacia la izquierda, todo en un lapso de tiempo de 10 s , cual es si veloci

zvonat [6]

Answer:

v = 1 i ^ m / s, v = 1 m / s

Explanation:

In this problem we show the difference between vectors and scalars.

The average speed is

v = Δx / Δt

The bold are vectors

Δx = 20-10 = 10 i^ m

v = 10/10

v = 1 i ^ m / s

the unit vector indicates that the velocity is on the x-axis

The average speed is

v =Δx / Δt

v = 10/10

v = 1 m / s

in this case we have a scalar
