According to multiple scientific experiments, most objects develop an attraction towards Candice.
Answer:
2000 pieces
Explanation:
The number of tiles is given by dividing the area of room by the area of each tile. In this case,
thw areas are as shown below
Area of room is 8*10= 80 m2
Converting dimensions of tiles from cm to m then
Area of tiles is 0.2*0.2= 0.04 m2
No of tiles is 80/0.04=2000 tiles
The average kinetic energy of an atom in helium gas at temperature T is given by,
K.E=
here, K is botzmann constant =1.38×10⁻²³ m² kg s⁻² K⁻¹
Given, K.E= 6.21×10⁻²¹ J
Substituting the values,
T= 300 K
Therefore, at temperature 300 K the average kinetic energy of the atom in helium gas is 6.21×10⁻²¹ J.
Answer:
Light microscopes use light and glass objectives to illuminate and magnify objects
Explanation:
Light microscopes and electron microscopes are used to study cells. The electron microscope has many times more resolving power than the ordinary light microscope. A light microscope contains an objective lens and an eyepiece through which the final image is seen.
Both light and electron microscopes magnifies the image of the object. The magnifying power of an electron microscope is many times that of the light microscope.
