If i step on a shard of glass while playing volleyball barefoot, which path will the reflex to pull my foot up follow?

1 answer:

4 0

sensory nerve - spinal cord - motor nerve - effector work together to cause the reflex to lift the foot.

<h3>What role does the spinal cord play?</h3>

The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lower back together. Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.

<h3>What occurs if the spinal cord is hurt?</h3>

Nerve function is lost beneath the site of damage. A spinal cord damage higher up can paralyze the majority of the body and all limbs (called tetraplegia or quadriplegia). Legs and lower body paralysis may result from a lower spinal cord injury (called paraplegia).

An object with a kinetic energy of 2160 J has a new mass of 120kg. What is it's velocity?

nadya68 [22]

Answer:

The velocity is 6 m/s

Explanation:

We use the formula of kinetic energy=

Ec= 1/2 x m x v2

2160 J = 1/2 x 120 kg x v2

v = $\sqrt[n]{x} 2160Joulex2/120kg\\$

v= 6m/s

1Joule= 1 kgm2/s2

The distribution of total body protein in healthy adult men is approximately Normal, with mean 12.3 kg and standard deviation 0.

Sophie [7]

Answer:

$P(12.25\leq x \leq 12.35 ) = 0.9876$

Explanation:

given,

mean (μ) = 12.3 Kg

standard deviation (σ ) = 0.1

random sample = 25

probability between 12.25 and 12.35 kg

$P(12.25\leq x \leq 12.35 ) = P(\dfrac{12.35-12.3}{\dfrac{0.1}{\sqrt{n}}}\leq z)- P(\dfrac{12.25-12.3}{\dfrac{0.1}{\sqrt{n}}}\leq z)$

$P(12.25\leq x \leq 12.35 ) = P(\dfrac{12.35-12.3}{\dfrac{0.1}{\sqrt{25}}}\leq z)- P(\dfrac{12.25-12.3}{\dfrac{0.1}{\sqrt{25}}}\leq z)$

$P(12.25\leq x \leq 12.35 ) = P(\dfrac{12.35-12.3}{\dfrac{0.1}{5}}\leq z)- P(\dfrac{12.25-12.3}{\dfrac{0.1}{5}}\leq z)$

$P(12.25\leq x \leq 12.35 ) = P(\dfrac{5 (12.35-12.3)}{0.1}\leq z)- P(\dfrac{5(12.25-12.3)}{0.1}\leq z)$

$P(12.25\leq x \leq 12.35 ) = P(\dfrac{2.5\leq z)- P(-2.5\leq z)$

using z-table

$P(12.25\leq x \leq 12.35 ) = 0.9938 - 0.0062$

$P(12.25\leq x \leq 12.35 ) = 0.9876$

What is the current in a 60.0 Ï resistor when the potential difference across it is 120.0 v?

nlexa [21]

The ohms law states that he potential difference of a current carrying conductor is proportional to the current and the resistance is constant.
therefore; mathematically; V = IR where V is the voltage , I is the current and R is the resistance in the conductor.
Making I the subject we get I=V/R
Therefore to get current we divide voltage by the resistance
I = 120 ÷ 60 = 2 Ampheres
Therefore the current is 2 Ampheres
