Answer:
The correct answer is - C. Multiply 500 by 1.5.
Explanation:
Given:
Force to move a desk = 500 N
weight of desk = 300 N
displacement = 1.5 meters
work done by Tine = ?
Formula:
work done (W) = F*d
where F is the force applied on the desk and d is the displacement of the desk.
Solution:
As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =
W = F*d
= 500*1.5
= 750 J
Thus, the correct answer would be option C.
Answer:
The mitochondria is the powerhouse of the cell
Since it’s natural environment is very acidic, putting pepsin in a very alkaline environment would cause it to denature.
Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
- <em>Winds.</em>
- <em>Temperature.</em>
- <em>Relative humidity.</em>
- <em>Rainfall.</em>
- <em>Pressure changes.</em>
- <em>Heat transfer.</em>
- <em>Hydrological dynamics.
</em>
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.
