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).

A mass M of 3.80E-1 kg slides inside a hoop of radius R=1.10 m with negligible friction. When M is at the top, it has a speed of

Vikentia [17]

Answer:

N = 26.59 N

Explanation:

given,

mass = 0.38 kg

radius of the hoop = 1.10 m

speed = 5.35 m/s

force = ?

now,

$\dfrac{1}{2}mv_t^2 + mg(2R) = \dfrac{1}{2}mv^2 + mgR(1-cos \theta)$

$mv^2 = mv_t^2 + 2mgR(1 + cos \theta)$

we know that,

$N - mgcos \theta = \dfrac{mv^2}{R}$

$N - mgcos \theta = \dfrac{mv_t^2 + 2mgR(1 + cos \theta)}{R}$

$N - mgcos \theta = \dfrac{mv_t^2 }{R}+ 2mg(1 + cos \theta)$

$N = \dfrac{mv_t^2 }{R}+ 2mg + 3mgcos \theta)$

$N = \dfrac{0.38\times 5.35^2 }{1.1}+ 2\times 0.38\times 9.8 + 3\times 0.38 \times 9.8 cos 34^0)$

N = 26.59 N

What is current of 12 ohm? help me pleasee

worty [1.4K]

1 Ampere

Explanation:

1/R = 1/8 + 1/10 + 1/12
1/R = (30 + 24 + 20) / 240
1/R = 74 / 240
R = 240 / 37
R = 120/37 Ohms
We know that,
V = IR
I = V/R
I = 12 / (120/37)
I = 12 × 37/120
I = 37/10
I = 3.7 A
Now,
The current in 12 ohm resistor →
= 1 A
∴ The current in 12 ohm resistor is 1 ampere
