Answer:30
Explanation:
Current=60 milliamps
Current=(voltage)/(resistance)
60=(voltage)/(resistance)
Doubling the resistance means multiplying both sides by 1/2
60x1/2=(voltage)/(resistance) x 1/2
30=(voltage)/2(resistance)
Therefore the resistance would be 30 milliamp if we double the resistance
That's called an "acceleration" or "slowing down".
Answer:
Thermal convection
Explanation:
When ice cubes are placed in water, ice cubes start melting. This is because water transfers its heat to ice cubes until the temperature becomes equal and the process is called "thermal Convection".
Thermal convection is the mode of transfer of heat energy that will occur when ice cubes will be added to the hot water and at the end of the experiment when both are at the same temperature, no ice cube will left.
Hence, the correct answer is "thermal convection".
<span>Static discharge differs from electric current because static discharge is described by C. lasting for only a fraction of a second.
This is a very short period of time, and electric current lasts longer than a static discharge does.

Answer: Natural selection is taking place.
Explanation:
As you can see, the lighter colored mice are more visible than their surroundings, so the hawk picks them off one by one. the brown mice on the other hand are less visible, blending in with their surroundings, so they are successful, and pass on the genes that allow them to survive better.
