Acceleration:</h3>
This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s²
To calculate the acceleration of the wishbone, we use the formula below.
⇒ Formula:
- F' = ma........................... equation 1
⇒ Where:
- F' = Net force between Kevin and Gamal
- m = mass of the wishbone
- a = acceleration of the wishbone
⇒ make a the subject of the equation
- a = F'/m....................... Equation 2
From the question,
⇒ Given:
- F' = 0.17 N
- m = 13 g = 0.013 kg
⇒ Substitute these values into equation 2.
- a = 0.17/0.013
- a = 13.1 m/s²
Hence, The initial acceleration of the wishbone is 13.1 m/s².

Answer:
A
Explanation:
If you do B, the wagon slows down due to friction
If you do C, it would slow down the wagon by half
If you do D, it would slow it down, due to there being more weight but same force.
A half-life is how long it takes for half of an element's particles to decay.
In 0 half-lives there will be 100% or 4/4 of the element left
After 1 half-life there will be 50% or 2/4 of the element's original particles left
After 2 half lives there will be 25% or 1/4 of the element's original particles left.
Since there is only 1/4 the original amount of the radium-226, we know that 2 half-lives have passed. Simply divide 3200 by 2 to get the time of 1 half-life.
3200/2 = 1,600 years is the half life of radium-226.
I really hope this helps you =)
Answer:
Explanation: It would go straight because objects in motion stay in motion and it would stay the same direction
