Answer: A. It consists of cranial and spinal nerves that spread throughout the body.
Explanation:
The peripheral nervous system (PNS) is made up of all nerves outside the central nervous system (CNS); includes all the cranial nerves that carry impulses to and from the brain and all the spinal nerves that carry messages to and from the spinal cord. This includes long nerve fibers as well as ganglia made of neural cell bodies. <em>The peripheral nervous system connects the central nervous system (CNS) to various parts of the body.</em>
The part of the body that constitutes the upper and lower extremities of the body along with the shoulder and pelvic girdles is the <em>appendicular skeleton.</em>
The part of the body that supports, protects, and allows bodily movement is <em>the skeleton</em><em>. </em><em>The skeleton</em> also provides the shape and form of the human body.
Answer:
a) t = 9.16*10^{-18} s
b) y = 0.402 mm
Explanation:
(a) To find the time that the particle takes to pass trough the region between parallel plates, you take into account that the horizontal component of the velocity is constant in all trajectory of the particle. Then, you use the following formula:
x: length of the sides of the plates = 0.22m
v_x: horizontal component of the velocity = 2.4*10^6 m/s
(b) To find the vertical displacement of the particle you first calculate the acceleration of the particle generated by the electric force:
where you have used that the charge is 1.6*10^-19 C (charge of an electron).
With the values of the acceleration and time you use the following kinematic equation to calculate the vertical displacement:
Answer:
Explanation:
We are asked to find the cyclist's initial velocity. We are given the acceleration, final velocity, and time, so we will use the following kinematic equation.
The cyclist is acceleration at 1.2 meters per second squared. After 10 seconds, the velocity is 16 meters per second.
- = 16 m/s
- a= 1.2 m/s²
- t= 10 s
Substitute the values into the formula.
Multiply.
We are solving for the initial velocity, so we must isolate the variable . Subtract 12 meters per second from both sides of the equation.
The cyclist's initial velocity is <u>4 meters per second.</u>
