<span>Use the cosine rule to solve for the distance the wind pushed them to the east and because this all happened in an hour, you can say they travelled this distance per hour.
+-130 km due east which means the wind speed was +-130km/h.
So for example i used a^2=b^2+c^2-2bc(cos75) b will be the distance they travelled and c= 135cos75=35km now all you do is substitute in and you will get your distance that the wind pushed them to the east and because it was an hour of travel the distance as said before will be per hour. </span>
Answer:
D. Newton's first law
Explanation:
Newton's first law of inertia says that an object will remain how it is, unless affected by an outside force. In this case, the plates want to remain stationary(not moving). Therefore, if you pull the table cloth fast enough, the force of friction produced will be small enough so that the Inertia of the plates will overcome the force of friction.
An indicator of average kinetic energy is temperature. Temperature is directly proportional to the average kinetic energy of the molecules in a substance.<span> If the degree of motion of the molecules inside an object doubles, the temperature will also double. Hope this answers the question.</span>
