Answer:
D
Explanation:
descriptive, because scientists are writing down the observations but not making comparisons.
Answer:
B
Explanation:
Simply take all forces pointing to the right of the box as positive and all of the forces pointing to the left of the box as negative and add all values.
ΣF = 7 + 18 + (-20) = 5N to the right
<span>Answer: The acceleration of 10 kg object is greater than that of 18 kg object.
Explanation:
According to Newton's Second law:
F = ma --- (A)
Let's find the acceleration for both 10 kg and 18 kg objects!
The net force on both of these masses = F = 20N
(1) Acceleration of 10 kg object
Mass = m = 10 kg
Plug in the values in equation (A):
20 = 10 * a
Acceleration = a = 2 m/s^2
(2) Acceleration of 18 kg object
Mass = m = 18 kg
Plug in the values in equation (A):
20 = 18 * a
Acceleration = a = 1.11 m/s^2
2 > 1.11; therefore, 10 kg object has the higher acceleration compared to the acceleration of the 18 kg object.</span>
