Answer 1

When operating pneumatically, a ten-car train requires greater caution due to its larger mass and momentum than a six-car train.

Step-by-step explanation:

When operating pneumatically, the train operator of a ten-car train must exercise greater caution than the operation of a six-car train because the longer train has a larger mass and momentum.

Pneumatic operation is based on the use of compressed air to power the train, and the force exerted by the air is directly proportional to the mass of the train.

Therefore, a longer train will require more force to stop or change direction, making it more challenging for the operator to manipulate and control the train.
