The answer is the atomic mass.
Answer:
3m/s²
Explanation:
Given parameters:
Mass of object = 3.2kg
Force to the right = 16.3N
Force to the left = 6.7N
Unknown:
Acceleration of the object = ?
Solution:
To solve this problem, we use newtons second law of motion;
Net force = mass x acceleration
Net force on object = Force to the right - Force to the left
Net force = 16.3N - 6.7N = 9.6N
So;
9.6 = 3.2 x a
a =
= 3m/s²
Answer:
b,c,d
Explanation:
gasses exert pressure, all particles of a gas sample move at the same speed. gas particles can exchange kinetic energy when they collide.
