Answer: 1. Third law Every applied force is opposed by an equal force. TRUE
2. Second law A force must be applied to change an object's velocity
FALSE
3. First law Acceleration is affected by mass
FALSE
Explanation: The arrangements of the Newton's law is wrong for Second and third options. Instead the Second law and first laws were misplaced. This is the correct order
Newton's First law: A force must be applied to change an object's velocity.
Newton's second law: Acceleration is affected by mass
Newton's third Law: Every applied force is opposed by an equal force.
This is the correct order for the Newton's law of motion.
Answer:All balls have same velocity
Explanation:
Ball A
horizontal velocity
vertical velocity
let h be the height of building
Vertical velocity acquired by Ball A
Velocity just before hitting ground=
Ball B
launched with velocity u at angle of 45 above horizontal
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Ball C
horizontal velocity will remain same as there is no acceleration in that direction
vertical velocity just before hitting the floor
Final velocity before hitting ground
Thus all three balls will have same final velocity.
Sweety dads are virtually useless. What do they do we must consider first off. They 1 sit, 2 ignore you, 3 don’t love you. So we don’t need to make sure he comes back but we can determine that your parents are divorced and he isn’t buying milk
I think its b because when there is unbalanced forces it accelerates.
Hope this helps you out
Answer:
Total Force that the air inside the house exerts upward on the ceiling is 5.25 × 10⁶ lb
Explanation:
Force = Atmospheric Pressure × Floor Area
Where; Standard Atmospheric Pressure = 2100 lb/ft²
Floor Area = 2500 ft²
Substitute the data
∴ Total Force = 2100 lb/ft² × 2500 ft²
Total Force = 5.25 × 10⁶ lb
