Answer:
Approximately 
assuming no heat exchange between the mixture and the surroundings.
Explanation:
Consider an object of specific heat capacity 
and mass 
. Increasing the temperature of this object by 
would require 
.
Look up the specific heat of water: 
.
It is given that the mass of the water in this mixture is 
.
Temperature change of the water: 
.
Thus, the water in this mixture would have absorbed :
.
Thus, the energy that water absorbed was: 
.
Assuming that there was no heat exchange between the mixture and its surroundings. The energy that the water in this mixture absorbed, 
, would be the opposite of the energy that the metal in this mixture released.
Thus: 
(negative because the metal in this mixture released energy rather than absorbing energy.)
Mass of the metal in this mixture: 
.
Temperature change of the metal in this mixture: 
.
Rearrange the equation to obtain an expression for the specific heat capacity: 
. The (average) specific heat capacity of the metal pieces in this mixture would be:
.
Answer:
the value of x is 3.7 because they are arranged in a particular manner.
"Venus" has all that characteristics. It has <span>a rocky mantle, iron core and very dense atmosphere that is 96.5% poisonous carbon dioxide and 3.5% nitrogen
In short, Your Answer would be "Venus"

Answer:
Explanation:
3. The word circuit means "go around", therefore a circuit is a pathway or closed path around which electricity (or water) flows.
4. Electrons flowing through a wire can be compared to water flowing through a hose. Once the flow of electrons or water is going, work, is performed.
5. You would get shocked in a bumper car by touching the floor and the ceiling at the same time. This means you are completing the circuit allowing electricity to flow.
6. Electricity from a wall outlet has enough energy to stop your
heart.
7. Electricity is the flow of electrons, because electrons move or jump from atom to atom.
8. Materials that allow electrons to move easily from atom to atom are called conductors.
9. Materials that do not allow electrons to flow easily are called insulators.
10. Semi- conductors are materials that are somewhere in between
.
11. Voltage is the force or pressure of electricity and is compared to the amount of water pressure in a hose.
12. Current (amps
) is the amount of electricity and is compared to the amount of water in a hose
.
13. Watts (power) is the term for work performed by electricity.
Answer:Cross-pollination is two plants that work together to pollinate and self-pollinate is when a flower pollinates itself. ... Why do you think plants surround the seeds with a yummy fruit? To protect the seeds so that they can reproduce. How is cross-pollination different from self-pollination?
