Which plastic can be bent and remoulded repeatedly? 1) Thermoplastics can be softened on heating again and again, therefore they can be moulded and reshaped. Thermosetting plastics cannot be softened on heating, therefore they cannot be moulded and reshaped. 2) Thermoplastics can be bent easily. Thermosetting plastics cannot be bent as they break when forced […]

Can humans survive 130 degrees?
Can humans survive 130 degrees? In the range of 90˚ and 105˚F (32˚ and 40˚C), you can experience heat cramps and exhaustion. Between 105˚ and 130˚F (40˚ and 54˚C), heat exhaustion is more likely. You should limit your activities at this range. An environmental temperature over 130˚F (54˚C) often leads to heatstroke. Why does NYC […]
What happens when you wrap a wire around a nail?
What happens when you wrap a wire around a nail? By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet.

The Trans-Pecos is the driest region in the state, with an average annual regionwide precipitation of 11.65 inches, while the Upper Coast (45.93 inches) and East Texas (44.02 […]
What happens if you increase the frequency?
What happens if you increase the frequency? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength […]
What is change in motion called?
What is change in motion called? Speed and direction of motion is velocity. A change in speed is a change in velocity – so, a change in speed is an example of acceleration! Page 2. Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. What is the rate change in velocity? The […]
