Answer:
, it will sink
Explanation:
The density of an object is given by
where
m is the mass of the object
V is its volume
For the body in the problem, we have
m = 4 kg = 4000 g
Therefore, its density is
And the object will sink in water, because its density is larger than that of water, which is 
. (an object sinks when its density is larger than that of water, otherwise it floats).
<h2>
Answer: Nonmetals to Nonmetals </h2>
Covalent bonds hold non-metallic atoms together. These atoms have many electrons in their outermost level and have a tendency to gain electrons rather than to yield them.
In this case the bond is formed by sharing a pair of electrons between the two atoms, one from each atom. Then, this pair of shared electrons is common to the two atoms and holds them together, so that both atoms acquire more stability.
Therefore the correct answer is C.
Answer:
d) Forces are applied equally in all directions
Explanation:
Confining pressures are pressures imposed on a layer of soil by the weights of the layers on top of it. Confining pressures occur as a result of equal transmission of forces between the layers of a material (usually rock and soil).
It can also be described as an equal, all-sided pressure produced by overlying rocks in the crust of the earth. As the confining pressure increases, the critical elastic energy of the layers of the material transforms from linear to exponential.
Answer:
2.11 seconds
Explanation:
We use the kinematic equation for the velocity in a constantly accelerated motion under the acceleration of gravity (g):
Answer:The answer is when a metal plate is pressed against a fast spinning piece of steel hard enough to stop it. i know this because I just took a test and got this question and got it write
