How is a warm front different from a cold front? A. Warm fronts cause snow flurries in the winter, while cold fronts cause several days of rainy weather.

B. Warm fronts cause rapid changes in weather, while cold fronts cause several days of cloudy weather.

C. Warm fronts cause several days of cloudy weather, while cold fronts cause heavy snow in the winter.

D. Warm fronts cause thunderstorms in the summer, while cold fronts cause rain when the air is humid.

An easy way to calculate the amount of energy available at each level is to what?

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.

Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) receptively. what is the probable genotypes of the round seeds which produced f 1 ? rr & rr rr only rr & rr rr only rr only
