Answer:
18.9 m.
Explanation:
From the question given above, the following data were obtained:
Initial velocity (u) = 0 m/s
Final velocity (v) = 70 km/h
Height (h) =?
Next, we shall convert 70 km/h to m/s. This can be obtained as follow:
3.6 km/h = 1 m/s
Therefore,
70 km/h = 70 km/h × 1 m/s / 3.6 km/h
70 km/h = 19.44 m/s
Finally, we shall determine the height. This can be obtained as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 19.44 m/s
Acceleration due to gravity (g) = 10 m/s²
Height (h) =?
v² = u² + 2gh
19.44² = 0² + (2 × 10 × h)
377.9136 = 0 + 20h
377.9136 = 20h
Divide both side by 20
h = 377.9136 / 20
h = 18.9 m
Thus, the car will fall from a height of 18.9 m

I learned this last year but I don't remember. Sorry
The answer would be <span>B. 210.8 rounded to 210
When rounding, if the digit you are rounding is equal to or larger than 5, you round the number up. For example: 15 rounded up to 20. 99 rounded up to 100.
210.8 would be rounded up to 211 because the 8 is greater than five, so you have to round it up.</span>
And I gather that instead of trying it on your own, you want me to do it for you.
The force of gravity between two objects always involves the product of
both of their masses.
"Weight" is the force of gravity between a planet and an object on its surface,
so it depends on both masses.
When a rock, a space probe, or an astronaut goes to a different planet, its/his
mass doesn't change, but the mass of the body they're standing on is different.
So the weight of the rock or the astronaut is different from what it is on Earth.
