So we want to know how can we detect infrared rays without an instrument. Infrared rays or heat, are a part of electromagnetic spectrum. We have specialized nerve cells in our skin called thermoreceptors that can detect differences in temperature that are produced by infrared part of EM spectrum.
Answer:
the object with greater mass will experience a smaller acceleration and the object with less mass will experience a greater acceleration.
Explanation:
According to Newton's second law, when the same force is applied to two objects of different masses, the two objects will change mass.
The total resistance is the reciprocal of (1/7+1/5+1/4+1/2) = 0.915 ohm. The battery voltage makes no difference. It would be 0.915 ohm even if the resistors were connected in parallel and just laying in the drawer.
