Abook that has a mass of 0.5 grams is pushed across a table with a force of 20 newtons what is the acceleration of the book? a.10 m/s^2
b. 0.025 m/s^2
c.40 m/s^2
d.40 m/s

Explanation:

To solve this equation ,we need to apply Newton's second law. Which defines

Force = Mass* Acceleration

Mass  = 0.5 g = 0.5*10^-3 Kg

Force  = 20 N

Acceleration = Force / Mass

Acceleration  = 20 N /0.5*10^-3 Kg

Acceleration  = 40000 m/s^2

I believe you meant a mass of 0.5 Kg

In that case, the acceleration would be

Acceleration  = 40 m/s^2

Option C

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
