What happens to the stopping distance if velocity of a car is doubled? When you double the speed of your car, your braking distance quadruples. As shown below, every time you double your speed, you multiply your braking distance by four. This piece of information will be important for determining your total stopping distance. What […]
Which is better oxygen tank or oxygen concentrator?
Which is better oxygen tank or oxygen concentrator? Oxygen concentrators are portable and easy to use and are thus better than oxygen cylinders. Although at Rs 40,000-Rs 90,000, they are more expensive than cylinders (Rs 8,000-20,000), they require very minimal maintenance. Will low oxygen make you tired? You’ll develop low blood oxygen levels, a condition […]
Is the control group the independent variable?
Is the control group the independent variable? The independent variable is “controlled” or held constant in the control group. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an […]
What is the efficiency ratio formula?
What is the efficiency ratio formula? Definition of efficiency ratio The efficiency ratio is calculated by dividing the bank’s noninterest expenses by their net income. Banks strive for lower e fficiency ratios since a lower e fficiency ratio indicates that the bank is earning more than it is spending. What is the formula for productivity? […]
How do you increase surface area?
How do you increase surface area? The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder. How can you increase the surface area of water? Surface tension is the energy […]
What is the best form of power?
What is difference between balanced and unbalanced force?
What is difference between balanced and unbalanced force? If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of […]
What type circuit connection should a light bulb be connected to maintain maximum brightness?
What type circuit connection should a light bulb be connected to maintain maximum brightness? Answer. Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the voltage increases the brightness of the bulb. When a bulb in a series circuit is unscrewed all bulbs in the circuit go […]
What is difference matter and substance?
What is difference matter and substance? Answer. anything which occupies space and has mass is called matter. But the that has specific composition and chemical characteristics is substance. What is the substance of matter? substance: A form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom […]
Are AC and DC capacitors interchangeable?
Are AC and DC capacitors interchangeable? AC capacitor does not have polarity, but the constructions are generally based on films without any kind of electrolyte. DC is just a special case where the polarity of the voltage does not change, so you can use AC capacitors – as is – in a DC application. Why […]
