I'll say 300 years = 10 half-lives. Look at it backwards. Start with 1g, and double it every time you go back 30 years. (1) x (2)10 = 1,024 which is where you want to be. Since it took 10 doublings, that's 10 half-lives.
The motion is likely not to be a simple harmonic motion as required for the formula for the period of a pendulum to work properly. The angle of swing is likely to reduce.
It doesn't reduce.
The 5 percent kVp rule is a guideline used in radiography to optimize image quality while minimizing patient exposure to radiation. It states that increasing the kilovolt peak (kVp) by 5 percent can effectively reduce the required exposure time by approximately 50 percent, leading to less radiation dose to the patient. This rule helps radiologic technologists balance the need for adequate image brightness and contrast with the imperative to keep radiation exposure as low as reasonably achievable (ALARA).
reduce something is to make the amount of something smaller. For example you can reduce your electric bill by unplugging the refrigerator.
Reduce refers to your usage of non-recycleable materials.
To calculate the heat required to reduce the temperature of steam from 212°F (100°C) to a lower temperature, you need to know the final temperature. The heat required can be calculated using the formula ( Q = mc\Delta T ), where ( m ) is the mass of the steam, ( c ) is the specific heat capacity of steam (approximately 2.01 J/g°C), and ( \Delta T ) is the change in temperature. If you provide the final temperature, I can give you the specific amount of heat required.
reduce the amount of exposure required to produce an image.
reduce the amount of energy required for activation
they reduce the activation energy required for the reaction to occur
That is the function of a catalyst.
Recycling reduce the energy of processing raw material and made into the product, it also reduce the energy required for the waste management process.
they reduce the activation energy required for the reaction to occur
no because proper nutrition are required for our body.
The time required for a radioactive mass to reduce by a factor of 2 is called the half-life. It is the time it takes for half of the radioactive nuclei in a sample to decay.
More workplaces are using Computers, and Computer related devices to speed production, reduce cost and unfortunately reduce the required workforce.
Dramatically reduce its involvement in the economy
Pulleys reduce the force required to lift heavy objects.
