Answer:
C) It will accelerate.
Explanation:
According to Newton’s second law of motion, when an object is acted on by an unbalanced force, it will accelerate.
An unbalanced force will change the speed or direction (or both) of an object. A change in speed and/or direction is acceleration.
A) is wrong. The object will stop moving only if there is a balanced force in the opposite direction.
B) is wrong. The object will decrease speed only if the unbalanced force has a component opposite to the direction of motion.
d) is wrong. The object will increase speed only if the unbalanced force has a component in the direction of motion.
The answer is 100 Pa.
The formula for calculating pressure is :
<u>Pressure = Force ÷ Area</u>
<u />
We are given that :
We also know that :
<u>Force = mass ×g</u>
<u />
So, force will be :
Now, we can finally calculate pressure :
Long term because if you leave something out to be weathered then it can’t be unweathered because of the drastic change of the object.
