What is motion in science definition? Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity). What […]
Why does a charged particle moving at the right angle to the magnetic field follow a circular path?
Why does a charged particle moving at the right angle to the magnetic field follow a circular path? Because when the charged particles move at right angle to the direction of magnetic field, it experiences force which always acts perpendicular to the velocity. In other words, the force on the charged particle act as centripetal […]
Does the universe end?
Does the universe end? The end result is unknown; a simple estimation would have all the matter and space-time in the universe collapse into a dimensionless singularity back into how the universe started with the Big Bang, but at these scales unknown quantum effects need to be considered (see Quantum gravity). Who was God’s parents? […]
Which is less damaging plugging a 110 volt appliance into a 220 volt circuit or plugging a 220 volt appliance into a 110 volt circuit explain?
Which is less damaging plugging a 110 volt appliance into a 220 volt circuit or plugging a 220 volt appliance into a 110 volt circuit explain? Which is less damaging: plugging a 110-V appliance into a 220-V circuit or plugging a 220-V appliance into a 110-V circuit? If the appliance is an electric motor, applying […]
Are drift nets illegal?
Are drift nets illegal? California is set to officially ban commercial fishermen from using drift nets off its coasts. Drift nets are frequently linked to the deaths of sea turtles and marine mammals including whales and sea lions. Why are drift nets a problem? Because drift nets are not selective, many fish and marine mammals […]
What is the 1st trophic level called?
What is the 1st trophic level called? Level 1: Plants and algae make their own food and are called producers. Level 2: Herbivores eat plants and are called primary consumers. Level 3: Carnivores that eat herbivores are called secondary consumers. Level 4: Carnivores that eat other carnivores are called tertiary consumers. Why do humans have […]
How do you calculate the volume of a tank in Litres?
How do I measure my well depth?
Why current is not directly proportional to voltage?
Why current is not directly proportional to voltage? If power is a constant, then, yes, current and voltage are inversely proportional since power is their product. Ohm’s law says that voltage and current are proportional because resistance is constant. This fact, however, has nothing to do with constant power. Can voltage be equal to current? […]
How much oxygen is needed for combustion?
How much oxygen is needed for combustion? Oxygen. Air contains about 21 percent oxygen, and most fires require at least 16 percent oxygen content to burn. Oxygen supports the chemical processes that occur during fire. When fuel burns, it reacts with oxygen from the surrounding air, releasing heat and generating combustion products (gases, smoke, embers, […]
