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:
Increases with increase in mass
Explanation:
gravity is proportional to mass and inversely proportional to the square of the distance between them
F = GMm/d²
For the answer to the question above, first find out the gradient.
<span>m = rise/run </span>
<span>=(y2-y1)/(x2-x1) </span>
<span>the x's and y's are the points given: "After three hours, the velocity of the car is 53 km/h. After six hours, the velocity of the car is 62 km/h" </span>
<span>(x1,y1) = (3,53) </span>
<span>(x2,y2) = (6,62) </span>
<span>sub values back into the equation </span>
<span>m = (62-53)/(6-3) </span>
<span>m = 9/3 </span>
<span>m = 3 </span>
<span>now we use a point-slope form to find the the standard form </span>
<span>y-y1 = m(x-x1) </span>
<span>where x1 and y1 are any set of point given </span>
<span>y-53 = 3(x-3) </span>
<span>y-53 = 3x - 9 </span>
<span>y = 3x - 9 + 53 </span>
<span>y = 3x + 44 </span>
<span>y is the velocity of the car, x is the time.
</span>I hope this helps.
Answer:
Mass: the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.
Example: a person or object may be weightless on the moon because of the lack of gravity, but that same person or object maintains the same mass regardless of location. Knowledge of mass is crucial in science.
