Physics Why are we able to hear short wave broadcasts better than long wave broadcasts ? Short waves are unaffected by atmospheric disturbances. By convention, short waves are meant for long distances, whereas long waves are reserved for short distances. Short wave broadcasts are made by nearby radio stations. Short waves are more energetic than long waves. Short waves are unaffected by atmospheric disturbances.

Physics It is easier to roll a barrel full of coal tar than to pull it because coal tar is a liquid and it flows in the barrel when it is rolled more surface area of the barrel is in contact with the road when it is pulled the rolling friction is much less than the sliding friction the full weight of the barrel comes into play when it is pulled coal tar is a liquid and it flows in the barrel when it is rolled more surface area of the barrel is in contact with the road when it is pulled the rolling friction is much less than the sliding friction the full weight of the barrel comes into play when it is pulled ANSWER DOWNLOAD EXAMIANS APP
