Answer:
c) A series of RC circuits.
Exactly the same
Explanation:
Objects looks exactly the same when viewed through a transparent object. A transparent body allows light to pass through completely. Therefore, the image formed will completely resemble that of the object to be viewed.
Examples are air, glass, pure water.
A translucent body partially allows light to pass through it. Most times, the image is not clear and it is distorted.
An opaque object will not allow light pass through it. It completely obstructs the ray of path of light. An opaque body will produce an image on the screen.

Answer:
upper motor neurons in the premotor cortex
Explanation:
Motor neurons are a type of nervous system cells that are located in the brain and in the spinal cord. They have the function of producing the stimuli that cause the contraction of the different muscle groups of the organism. They are therefore essential for daily activities that require muscle contraction: walking, talking, moving hands and in general all body movements.
The centripetal acceleration is 172 m /s^2.
<u />
<u>Explanation:</u>
The acceleration that causes an object to move along a circular path, or turn is known as the centripetal acceleration. Centripetal acceleration points radially inward from the object's position and making a right angle with the object's velocity vector.
The centripetal acceleration is given as
Ac = v^2 / r
where Ac represents the centripetal acceleration of an object.
v represents the linear velocity
r represents the radius of rotation.
Given t = 0.64 s, r = 1.8 m.
To find linear velocity, v = (2 * pi * r) / t
= (2 * 3.14 * 1.8) / 0.64
v = 17.6 m / s.
Centripetal acceleration = v^2 / r
= (17.6 * 17.6) / 1.8
= 172 m / s^2.
Answer:
9.7 ms⁻¹
Explanation:
The formula to find the acceleration is :
According to the question, we are asked to find the Final Velocity.
For that, let the Final Velocity be x.
Therefore,
Final velocity = 9.7ms⁻¹
