Answer:
In metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
Explanation:
Here we asked to divide 1 meter in to 100 equal parts.
Let us find out what is the length of piece when 1 m is divided in to 100 equal parts.
Length
That is length of 1 m divided into 100 equal parts is 0.01m.
We know that 0.01 m is 1 centimeter.
So, in metric prefixes, if a meter were divided into 100 equal-sized subunits, a single unit would be called a centimeter.
D. Copper and Gold
Copper and gold are used a lot in electrical applications.
Air and wood are insulators and glass is also kinda bad...
Answer:
The atoms are aligned in a particular direction
Explanation:
The atoms become aligned in a particular direction in regions called domains, thus resulting in an overall resultant magnetism due to the spin of the electrons.
answer
Height at which kiwi reach=1.2m
Solution
In this question we have given
mass of apple,
mass of kiwi,
height from which apple is dropped,
Let the height at which kiwi reached is
here,
We will apply law of conservation of energy
it means,
potential energy of kiwi= potential energy of apple
......(1)
here g is gravitational acceleration
put values of and in equation 1
therefore, Height at which kiwi reach=1.2m
Answer:
6logs
Explanation:f
First finding the volume of the logs
V= π/4d²l
= 0.098m³
So number of logs will be
Weight of 2 boys + weight of log = buoyancy force.
So
2( 400)+ N ( Mlog x g) = density of water x volume displaced x g
2(400) = N x 0.098x 1000x 9.8 x 0.9- 0.75* 1000
N= 5.5 which is approx 6logs
