Answer:
Digestive juices secreted by various organs such as salivary glands in the mouth, stomach, liver and pancreas help in the process of digestion of food. Saliva secreted by the salivary glands in the mouth aids in the breakdown of starch present in the food to simple sugar
Explanation:
Contact and non contact forces are big factors to consider
in designing of different modes of transportation because this factors are
resistances for the mode of transportation. These contact and non- contact
forces should be minimized in order for the energy requirement to be also
minimum. But not the extent of risking the safety, for example a non contact
force is the wieght, the should be optimum, safety of the design should not be
compromised just to reduce weight, just like by removing essential parts,
support just to remove weight is not good.
Answer: 0.73 g/cm3 and YES the questionable ball in this range of acceptable density
Explanation:
Answer:
Electrons are negatively charged and are deflected on a curving path towards the positive plate. Neutrons have no charge, and continue on in a straight line.
Answer:
the hot bulb will have high resistance to the flow of current. While the cold bulb will have a low resistance to the flow of current.
Explanation:
A conductor that does not obey Ohm's law is described as non - ohmic. An example is a filament lamp. It glows as the current passes through it.
How does the resistance of the light bulbs differ when the bulbs are cold and when the bulbs are hot ?
The resistance of the light bulbs increase gradually as its temperature is increased.
So, the hot bulb will have high resistance to the flow of current. While the cold bulb will have a low resistance to the flow of current.
Because the resistance of an impure metal wire is greater than the resistance of a pure metal wire of the same dimension.
