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.
reduce something is to make the amount of something smaller. For example you can reduce your electric bill by unplugging the refrigerator.
3 1/4 doesn't reduce
Reduce refers to your usage of non-recycleable materials.
reduce the amount of energy required for activation
reduce the amount of exposure required to produce an image.
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.
no because proper nutrition are required for our body.
they reduce the activation energy required for the reaction to occur
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
Alcohol is metabolised by the body, so time is required.
Pulleys reduce the force required to lift heavy objects.
