<h2>Hello!</h2>
The answer is: The acceleration of the object B is half of the object A.
<h2>Why?</h2>
We can solve this problem applying the Newton's Second Law, which states that the product of the mass and the acceleration of a body is equal to the force applied to that body.
So,
For the object A, we have:
Calculating the acceleration we have:
[/tex]
For the object B, we have:
Calculating the acceleration we have:
[/tex]
Hence,
So, what is true about the acceleration of object A and object B?
The answer is that the acceleration of the object B is half of the object A acceleration since the mass of the object B is two times the mass of the object A.
Have a nice day!
Answer: Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. There for the answer is A
Answer:
The mass of the planet Newtonia is .
Explanation:
It is given that,
Mass of the bob, m = 1.25 kg
Length of the simple pendulum, l = 185 cm = 1.85 m
Time taken by the simple pendulum, T = 1.42 s
The circumference of Newtonia is measured to be 51,4000 km. The time period of the simple pendulum is given by the formula as:
g is the acceleration due to gravity on planet Newtonia
For one complete cycle, T = 2.84 s
The formula of acceleration due to gravity on any surface is given by :
Since,
So, the mass of the planet Newtonia is . Hence, this is the required solution.
Answer:
Yes, cause when listener is far away from music source... the listener feels it's pleasant.... but when observer approaches near loudspeaker... sound become unpleasant..........sound becomes noise when frequency crosses 85 Decibels.....so you can say that the voice from loudspeaker also get shrill when the listener reaches the surrounding source......
