The slower an object moves the more kinetic energy it has.<br><br> True<br><br> False
Lady_Fox [76]
False , because its backwards 

There will be more energy 'locked away' in a massive lorry that is moving at 20 m/s than in a motorbike travelling at the same speed.



Also the faster it goes the more kinetic energy the lorry will have.

A lorry moving at high speed will have much more kinetic energy than a lorry moving at low speed.

Therefore a fast moving car or lorry will cause more damage in an accident than a slow moving one because this kinetic energy has to be turned into other forms including sound, heat and stress on the other vehicles.

The kinetic energy of an object therefore depends on two things:
(a) the mass of the object (m)
(b) its speed (v)

The formula for kinetic energy of an object of mass m travelling at speed v is:

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 100x and an
Whitepunk [10]

Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.

In which position are the earth, moon, and sun during a new moon?
dimaraw [331]

Answer:

A. Moon is between the Sun and Earth

Explanation:

The new moon stage is the faze in which we can not see the Moon from Earth. In this stage, the Moon is lacking from the sky, or rather we can not see it because it is totally dark from the side that is facing the Earth. The reason for this is that the Moon is located between the Sun and the Earth. The Sun is making half of the Moon bright as it always does, but in this stage it is the half of the Moon that is facing the Sun, while the other half that is facing the Earth is totally dark as it doesn't receive any sunlight at that time.

Plants move water from the roots of the plant to the leaves through transpiration. As water evaporates from the leaf, cohesion p
adoni [48]

Answer:

Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.

Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
