Ateam of eight dogs pulls a sled with waxed wood runners on wet snow ( the dogs have average masses of 19.0 kg, and the loaded sled with its rider has a mass of 210 kg. (a) calculate the acceleration of the dogs starting from rest if each dog exerts an average force of 185 n backward on the snow. (b) calculate the force in the coupling between the dogs and the sled.

(a) The total mass of the dogs is:

The mass of the sled is:

So, the total mass is:

The total force exerted by the dogs is:

So, we can find the acceleration of the dogs by using Newton's second law:

(b) The acceleration we found at point (a) is also the acceleration of the sled, which has a mass of 210 kg. Therefore, the force exerted by the dogs on the sled is equal to the product between the mass of the sled and its acceleration:

answer: its c lololo

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
