Answer:
12m/s²
Explanation:
Two balls with equal masses and speed engage in a head-on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero.
Therefore, the second ball experience an acceleration of 12m/s² at the same time.
Because the speedometer responds directly and proportionally to acceleration (whether speeding up or breaking). If the speedometer displayed average speed it would not be directly affected by changes in speed due to acceleration
The answer is a. momentum
It add to the pollution to the air and the waste is throw into the ocean
Answer:
The new time period will be T.
Explanation:
The time period in terms of spring constant and mass is given by :
If mass and force constant is doubled, m' = 2m and k' = 2k
New time period is given by :
So, the new period will remains the same. Hence, the correct option is (C).
