Which scientist died a virgin? Isaac Newton Who died from eating mercury? Karen Elizabeth Wetterhahn (October 16, 1948 – June 8, 1997) was an American professor of chemistry at Dartmouth College, New Hampshire, who specialized in toxic metal exposure. She died of mercury poisoning at the age of 48 due to accidental exposure to the […]
How many molecular orbitals will have an N value of 2?
How many molecular orbitals will have an N value of 2? Explanation: The atomic orbitals with an n value of 2 are the 2s orbital and the three 2p orbitals. When these four orbitals from one atom interact with four orbitals from another atom, they generate 8 molecular orbitals, half of which will be bonding […]
Why is my diastolic pressure high?
Why is my diastolic pressure high? A: A high diastolic blood pressure (80 mm Hg or higher) that stays high over time means you have high blood pressure, or hypertension, even when systolic blood pressure is normal. Causes of diastolic high blood pressure include both lifestyle factors and genetics, but the disease is multifactorial. Why […]
Do gamma rays travel faster than light?
Do gamma rays travel faster than light? Although the energy inherent to light is quantized into discrete energy packets (a.k.a., photons), there are some properties shared by all forms of light. Light of any wavelength, from picometer-wavelength gamma-rays to radio waves more than a trillion times longer, all move at the speed of light in […]
What forces act on a still object?
What forces act on a still object? Force is defined as a push or pull acting on an object. Forces include gravity, friction, and applied force. Force causes changes in the speed or direction of motion. These changes are called acceleration. What forces can change the shape of an object? When a force acts on […]
What are two signs of hydroplaning?
What are two signs of hydroplaning? It’s sometimes hard to tell when you’re hydroplaning. The vehicle’s rear end may be a little squirrelly. Steering may feel loose or too easy. Watch for standing water or spray from vehicles in front of you. Should I buy AWD or FWD? It’s lighter, so front-wheel drive cars tend […]
What are the disadvantages of using a pinhole camera?
What are the disadvantages of using a pinhole camera? The image formed does not give any details. Usually, it is faint. Image is obtained on the screen and no permanent record of the image can be obtained. Pinhole camera cannot be used for studying moving objects. What are the major differences between a pinhole camera […]
What are the factors that affects air pressure?
What are the factors that affects air pressure? Discuss the factors affecting atmospheric pressure with respect to the following: Temperature Altitude Rotation of the Earth Temperature. Altitude. Rotation of the Earth. What are examples of external factors? External factors political – For example, new legislation. economic – For example, inflation and unemployment. social – Changes […]
What is heat loss by radiation?
What is heat loss by radiation? Radiation is a form of heat loss through infrared rays. This involves the transfer of heat from one object to another, with no physical contact involved. For example, the sun transfers heat to the earth through radiation. The last process of heat loss is evaporation. How can a patient […]
What is the relationship between angular speed frequency and period?
What is the relationship between angular speed frequency and period? Period, , is defined as the amount of time it takes to go around once – the time to cover an angle of radians. Frequency, , is defined as the rate of rotation, or the number of rotations in some unit of time. Angular frequency, […]
