Invention is the creation of a product and innovation is when someone improves on or makes a significant contribution to an existing product.
Answer:
35 mph
Explanation:
From the question given above, the following data were obtained:
Time (t) = 2 hours
Distance (d) = 70 miles
Speed (S) =.?
Speed is simply defined as the distance travelled per unit time. Mathematically, it is expressed as:
Speed (S) = Distance (d) / Time (t)
S = d/t
With the above formula, we can calculate how fast (i.e the speed) Joe will need to drive to make it to his Grandma's house on time. This can be obtained as follow:
Time (t) = 2 hours
Distance (d) = 70 miles
Speed (S) =.?
S = d/t
S = 70/2
S = 35 mph
Therefore, Joe will drive at 35 mph in order to get to his Grandma's house on time.
Answer:
This can be translated to:
"find the electrical charge of a body that has 1 million of particles".
First, it will depend on the charge of the particles.
If all the particles have 1 electron more than protons, we will have that the charge of each particle is q = -e = -1.6*10^-19 C
Then the total charge of the body will be:
Q = 1,000,000*-1.6*10^-19 C = -1.6*10^-13 C
If we have the inverse case, where we in each particle we have one more proton than the number of electrons, the total charge will be the opposite of the one of before (because the charge of a proton is equal in magnitude but different in sign than the charge of an electron)
Q = 1.6*10^-13 C
But commonly, we will have a spectrum with the particles, where some of them have a positive charge and some of them will have a negative charge, so we will have a probability of charge that is peaked at Q = 0, this means that, in average, the charge of the particles is canceled by the interaction between them.
Answer and Explanation:
They are both correct.
This is because potential energy is when there is potential for the object to have energy, while kinetic energy is energy that is moving already.
So, as the ball falls, it loses its potential energy, or "still/Stalled" energy, and gains kinetic energy, or moving energy.

It lasts 29 1/2 days.
-the sidereal month- is the true period of the moon's revolution around Earth. It lasts 27 1/3 days.
-the difference of 2 days between the synodic and sidereal cycles is due to the Earth- moon system also moving in an orbit around the sun.
