A PTA is treating a patient who has neurological impairments. The PTA is concerned that the patient may not have joint position awareness. The PTA proceeds to test this patient by moving the ankle through a small range of motion and asking the patient to report the direction of movement while it is moving. Which of the following tests is being employed?

The impedance of an autotransformer is higher than the impedance of a two-winding transformer.

Reduced-voltage motor starting is a method of reducing the current through the motor windings and reducing the load on a power distribution circuit during motor starting.

For a ___ application, the source is applied across the entire coil, which acts as the primary.

An autotransformer should be provided with external impedance in ___ in the circuit, such as from other transformers or reactors, or the impedance of the power lines.

When a rotor approaches synchronous speed, ___ is applied to the wound-rotor section and the motor pulls into synchronous speed.

A two-winding transformer wired as an autotransformer can deliver more power to a load than when wired as a two-winding transformer.

Autotransformer starting is one of the least effective methods of reduced-voltage starting.

A physical therapist assistant has been treating a patient for 2 weeks who has spasticity. The PTA enters the patient’s room in the afternoon and notices that the patient’s spasticity is significantly stronger than from the morning visit. Which of the following reasons would be the least likely cause for this change?

Figure 4: Cancer Cell Classification Predicted Class Cancer Predicted Class Normal Actual Class Cancer 250 45 Actual Class Normal 429 1875   Review the table labeled Figure 4: Cancer Cell Classification. You trained a model for detecting cancer cells in medical images, and the table contains the classification results. If the positive class is cancer cells, what is the accuracy and F1 score of the classification?
