Answer:
Characteristics passed down from parent to offspring.
Explanation:
Inherited traits are given to the offspring from the parents.
"Characteristics are passed down from the offspring to the parent" does not make sense.
"The offspring of a plant" and "The parent of an offspring" are wrong.
Answer:
Explanation:
deceleration a
v² = u² - 2as
0 = 7.5² - 2 a x .15
a = 187.5 m / s²
If R be the force exerted by hand
R- mg = ma
R = mg + ma
= .27 ( 9.8 + 187.5 )
= 53.27 N
Work done by hand
= force x displacement
= 53.27 x - .15
= - 8 J
A kind of stimulus is that Optic flow. It occurs as spaceships in Star Wars accelerate to near-light speed and the stars appear to stream outward from the screen's Centre due to centripetal force.
providing the impression of forward momentum. The acceleration vector of an object undergoing UCM is always directed toward the centre because centripetal implies "towards the Centre."m Since the reference frame is spinning, centrifugal force—which is not a real force—occurs as a result of this motion. The centripetal force, which pushes the item in the direction of the circle's Centre and maintains uniform circular motion is called centripetal force, is the real driving force behind uniform circular motion.
The pattern of seemingly moving objects, surfaces, and edges in a visual scene that is brought on by the motion of the observer in relation to the scene is known as optical flow or optic flow. Another way to think of Optic flow is as the distribution of apparent motion velocities of brightness pattern in an image.

Taking into account the definition of electron affinity, negative electron affinity means that the anion of the element is more stable than the neutral atom.
Electron affinity is the energy exchanged when a neutral, gaseous atom, and in its ground state, captures an electron to form the anion.
In other words, electronon Affinity is the energy that is given off when a neutral atom in the gaseous state captures an electron to become a negative ion.
The value can be positive or negative. A negative electron affinity means energy must enter in order to bind an electron to the ion, being an endothermic process. If electron affinity is positive, the process is exothermic and occurs spontaneously.
Then, the negative electron affinity (energy is released) occurs when the atoms acquire a more stable configuration when capturing an electron, so the attractive force will predominate. Positive electron affinity (energy is absorbed): occurs when you have to provide energy to the atom to capture the ion.
In summary, negative electron affinity means that the anion of the element is more stable than the neutral atom.

The upward force exerted by the elevator floor on the passenger is 7.6 times mass of the passenger.
<h3>What is force?</h3>
A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in question elevator accelerates downwards with an acceleration of 1.2 m/s². There is acceleration due to gravity working downward which is 9.8 m/s².
So, net acceleration due to gravity is given as 9.8 - 1.2 = 7.6 m/s²
The upward force exerted by the elevator floor on the passenger is mass times acceleration, 7.6 times mass of passenger.
