Answer:
When adolescents get enough calcium during the teen years, they can start out their adult lives with the strong bones and significantly reduce their risk for fractures as an adult. Inadequate calcium intake during adolescence and young adulthood puts individuals at risk for developing osteoporosis later in life.
Answer:
Basically W = mg, as you can see, W varies directly as m where g is a constant (9.81 m s^-2 for Earth) , this explains why the more mass an object has,the greater its weight
Explanation:
Power is calculated by dividing the work done with the time interval of the motion. Work, on the other hand, is force times the distance traveled. Therefore, we can calculate as follows:
60.0 mi/h = 26.82 m/s
The car accelerates at:
<span>v2 = v1 + at </span>
<span>a = [v2 - v1] / t </span>
<span>a = 1.49m/s² </span>
<span>The distance it travels at this acceleration in 15.0 s is: </span>
<span>d = [v1 + v2] t / 2 </span>
<span>d = (0 + 22.4m/s)15.0s / 2 </span>
<span>d = 168m </span>
<span>P = m (a)(d) / t </span>
<span>= (1300kg) (1.49m/s²) (168m) / 15.0s </span>
<span>= 22,700 W</span>
Answer:
Empirical evidence are evidences obtained by direct observation, sensual perception or direct measurement. It is the processed and useful data gathered and stored in a material form or documented to provide record of the measurement.
With the aid of empirical evidence, it is possible for researchers to find answers to question regarding topics that can vastly impact every day life.
With empirical evidence, it is possible to determine the effects of treatment in a study such as the invention of working car safety devices such as seat belts and airbags.
Explanation:
Generally, rings form from moons, asteroids, or comets that have disintegrated due to a collision or because they got too close to their planet (Roche Limit). ... Most of the debris, however, will not have enough energy to overcome the planet's gravity and will remain in orbit around the planet.
