Assuming that you mean to ask <em>. . . "What is 7.4 </em><u><em>as a fraction</em></u><em> in simplest form</em>?"
7.4 = 7 and 4/10
4/10 can be reduced to 2/5
7 represents = (7*5)/5 = 35/5
so . . 7 + 4/10 = 35/5 + 2/5 = 37/5 (improper fraction in simplest form)
or
. . . . 7 + 4/10 = 7 2/5 (mixed fraction in simplest form)
Answer:
Length of the stake will be 0.3623 m
Explanation:
We have given energy required to fully drive a stake into ground = 0.30 KJ = 300 J
Average resistive force acting on the floor is equal to F = 828 N
We have to find the length of the stake
We know that work done is given by
W = Fd, here W is work done , F is average force and d is the length of the stake
So 300 = 828×d
d = 0.3623 m
So length of the stake will be 0.3623 m
To calculate the volume of the diamond, we use the formula
Here, 
is the density and its value given 
and m is mass and its value given
.
1 carat = 200 mg = 0.200 g
So mass of the diamond, 
Substituting these values in above equation we get,
Thus the volume of given carat diamond is 
.
Answer:
They come from metal elements or alloys.
Explanation:
Different materials produce magnets of varying strengths. Ceramic magnets, also known as ferric magnets, are made of iron oxide in a ceramic composite. Samarium cobalt magnets are created from the combination of cobalt and samarium, which is a rare-earth element. Neodymium magnets contain boron, iron and neodymium, also a rare-earth element. The strongest naturally occurring magnet is lodestone, a form of magnetite. It attracts even small objects, such as staples and paper clips.
