You are correct, the answer is C.
Good insulators are materials that do not allow heat, electricity, light or sound pass through easily. Materials like steel and silver (which are metals) are not good insulators because they make good conductors. They easily allow heat, electricity and the like pass through them.
Thus, the answer is letter C. Rubber.
Answer:
they move towards the positive side... that's option 2
Main Answer:
Assume that the temperature rises by 9.9 F
Initial Temperatures will be C1, F1
Final temperatures will be C2, F1 + 9.9
The relation between celsius and fahrenheit temperature is as follows:
C = 5/9(F - 32)
Increase in temperature in celsius will be
C2 - C1 = F2 - F1
C2 - C1 = 5/9 ( F1 +9.9 -32) - 5/9 ( F1 -32)
C2 - C1 = 5/9 ( F1 +9.9 -32 - F1 +32)
C2 - C1 = 5/9 (9.9)
C2 - C1 = 5.5C

What is temperature?
Temperature is defined as the degree of coldness or hotness of an object or a substance. Generally, it is measured in various temperature scales. They are celsius, fahrenheit, kelvin.

Answer:
Explanation:
Given equation is ,
x =t + 2 t³ ,
dx/dt = velocity ( v ) = 1 + 6 t²
a) kinetic energy = 1/2 m v² = .5 x 4 ( 1 + 6 t² )² = 2 ( 1 + 6 t²)²
b ) Acceleration = dv /dt = 12 t .
force( F ) = mass x acceleration = 4 x 12 t = 48 t
Power = force x velocity = 48 t x ( 1 + 6 t²). = 48 t + 288 t³ )
work done = ∫ F dx =∫ 48 t x( 1 + 6t² )dt ; = [48t²/2 + 48 x 6 x t³ /3 = 24 t² + 96 t³ )]₀² = 864 J
