Subtract 12−(−8). (1 point)
To subtract 12 - (-8), we need to apply the rule of subtracting a negative number, which is equivalent to adding its positive. Thus, the equation becomes:
12 + 8 = 20.
Therefore, 12 - (-8) is equal to 20.
A diagram shows how gravity on Earth works on an object located in different spots in a seaside community. Where is gravity between Earth and an object the strongest? (1 point)
Responses
when the object is on the highest branch of a pine tree
when an object is at sea level
when the object is on top of a telephone pole
when the object is on top of a nearby mountain
The gravity between Earth and an object is the strongest when the object is on top of a nearby mountain. The force of gravity is greater at higher elevations, so being on top of a mountain would experience a slightly stronger gravitational pull compared to being at sea level or on top of a telephone pole.
