Question

The ideal angle for the welding torch is ___ degrees.

A) 45
B) 60
C) 90
D) 120

Answer 1

The correct option is A. In physics, the ideal angle to launch a projectile to cover the maximum distance is 45°. Neither 0°, 60°, nor 90° provide the conditions for maximum range, where 0° and 90° both result in a range of zero.

Step-by-step explanation:

The ideal angle for the welding torch often depends on the specific welding technique and position, but the question appears to be related to projectile motion, which is a topic in physics. In the context of projectile motion, the optimum angle at which a projectile should be launched to cover the maximum distance is 45°. This is because, at this angle, the horizontal and vertical components of the initial velocity are equal, which results in the greatest range.
