Heat is how hot something is, temperature is how hot or cold something is.
Answer:
54mph
Explanation:
Speed is defined as the change in distance of a body with respect to time.
Let x be the speed of Eric on his way to the football game, if he used 11hours to the football game, his distance will be the product of his speed and time taken i.e
Distance = speed × time
Distance= x × 11
Distance = 11x... (1)
During his return journey, his speed increases by 12mph with a return drive in only 9hours i.e speed = x+12 and time is 9hours
Since distance = speed × time (return Journey)
Distance = (x+12)×9
Distance = 9x+84...(2)
Note that the distance to and fro the journey is the same as such we will equate equations 1 and 2 to get his initial speed "x" to have;
11x = 9x+84
11x-9x = 84
2x = 84
x = 42mph
This means that his initial speed on his way to the football game is 42mph. Since his speed increases by 12mph during his return drive, his return speed will be 42mph + 12mph which gives 54mph.
The answer to this is true. Usually when a volcano forms it starts off from the ocean floor then it will form up towards the surface. Volcanoes are also known for creating new islands like for example The Hawaiian Chain, it was created by volcanoes. in order for the islands to form, the plates in the ocean floor aka where the volcanoes are located has to push up another rock aka an island. Molten rock falls into the ocean and hardens creating a new island.
Li2O is the molecular formula for lithium oxide.
The y-component of the force on the particle at the given position is 120 N.
<h3>
Electric force on the particle</h3>
The electric force on the particle is determined by applying Coulomb's law and work-energy theorem as shown below;
Fd = W
Where;
- F is the applied force
- d is the distance
- W is potential
F = W/d
F = 60/0.5
F = 120 N
Thus, the y-component of the force on the particle at the given position is 120 N.
