g100num [7]2 years ago

Explanation:

Given

mass of coolie = 40 kg

Mass of salt = 20 kg

Total mass (m) = 40 + 20 = 60 kg

Displacement (h) = 20*20 = 400 CM = 4 m

Work done (w) = ?

Power (P) = ?

We know we have the formula

work done =force × displacement

or work done = m * g * h

work done = 60×10×4

work done = 2400 joules

Similarly

power = work/time

power = MGH/time

power=60×10×4/120

power=2400/120

power= 20watt

Hope it will help you :)❤

Bacillus anthracis, the bacterium that causes the deadly disease anthrax produces thick endospores. What is the significance rol
egoroff_w [7]
The significant role of spore formation in the reproductive cycle of this bacterium would be to allow the bacteria to survive in extreme conditions. The spore formed is called an endospore which is a thick cover made of protein. These spores are mostly resistant to heat and chemicals which makes the bacteria survive in harsh conditions. Spores can only be destroyed by sterilization and it require very high pressures and very temperatures. In microbiology and medical settings, this process is usually done in a device known as the autoclave. Sterilization is a process that involves the killing of all microorganism in a system whether it is harmful or beneficial.
