Well, you don't need enzymes (biological catalysts) if you're willing to wait a century or two to digest a burger.
Without catalysts, complex reactions like digestion would take too long and the organism could not extract energy from the nutrients it eats in a practical time frame.
In addition, speed is everything in the biological world.
Some reactions and their speed relative to other organisms reactions determines who survives and who doesn't, among other aspects of life.
If a plant is slow to photosynthesize and grow in a habitat high in competition for sunlight real estate, other autotrophs will surely take over.
From the information given, the mass of the hammer seems to be 1.36 kg and the velocity by which it is wielded seems to be 22 m/s.
The most suitable formula to be used here is :
f = m × v
where f is force, m is mass and v is velocity.
f = m × v → f = 1.36 × 22 → f = 29.92 kg m/s
Therefore the force generated by the hammer is 29.92 N
( kg m/s is the same as Newton)
Answer:
Fusion powers the Sun and stars as hydrogen atoms fuse together to form helium, and matter is converted into energy. Hydrogen, heated to very high temperatures changes from a gas to a plasma in which the negatively-charged electrons are separated from the positively-charged atomic nuclei (ions).
I hope it's helpful!
Answer:
positively charged
they are located in an atom in the nucleus
