The statement is incorrect because the device that transforms electrical energy into a useful function, such as heat or light, is not power itself. Power is the rate at which energy is transferred or converted. The device that actually transforms electrical energy into a useful function is called a load or an appliance, such as a light bulb or a heater.Rate this question:

Correct Answer
A. Hemolytic anemiaExplanation
Rh incompatibility occurs when a pregnant woman with Rh-negative blood is carrying a fetus with Rh-positive blood. If the mother's immune system becomes sensitized to the Rh-positive blood, it can produce antibodies that attack and destroy the red blood cells of the fetus. This condition is known as hemolytic anemia, which can be severe and potentially fatal for the fetus if left untreated.Rate this question:

Projectile motion refers to the motion of an object launched into the air at a specific _________
- A.
Trajectory
- B.
Angle
- C.
Percentage
- D.
Equation
Correct Answer
B. AngleExplanation
Projectile motion refers to the motion of an object launched into the air at a specific angle. The angle at which the object is launched determines the shape of its trajectory, which is the path it follows through the air. The angle affects both the range and the height of the projectile's flight. A higher launch angle will result in a longer flight time and a higher peak height, while a lower launch angle will result in a shorter flight time and a lower peak height. Therefore, the angle is a crucial factor in determining the motion of a projectile.Rate this question:
