The answer is 117.6 J
The potential energy of
the object is actually its stored energy:
<span>E =
m · g · h
E - the potential energy of the object,
m - the mass of the object,
g - acceleration due to gravity,
h - the height of the object.
m = 4 kg
g = 9.8 m/s</span>²
h = 3 m
E = 4 * 9.8 * 3 = 117.6 J
Answer:
30m/s
Explanation:
From law of motion equation
Vf= Vi + at
Where Vf= final velocity
Vi= initial velocity=0(the car started at rest)
a= acceleration= 3m/s2
t= time= 10s
Then substitute into the equation to get the final velocity.
Vf= 0+(10×3)
Vf= 30m/s
Hence, the car's final velocity is 30m/s
When the lemon is cut, it releases gaseous molecules into the surrounding air which are responsible for the lemon's smell. These molecules move slowly at room temperature and the distance that they must cover, in relevance to their size, is immense. These reasons contribute to the fact that the smell takes a while to reach the other side of the room.
Answer: strength.
Explanation: The simulation made the strength an independent variable and dependent variable.
Area under the line and above the axis on a velocity - time graph represents the displacement of the object.
