It would be A:facing disagreement forces scientist to prove their theories more consistently :)
Answer:
the change in momentum = Force x change in time
Answer:
A) Electrons only
Explanation:
In quantum mechanics, "electron cloud" refers to the region of space where electrons can be found in an atom. In fact, in quantum mechanics, it is not possible to predict the exact position of the electrons, so there is a region where electrons have a certain probability to be found.
Answer:
The total electrical power we are using is: 1316 W.
Explanation:
Using the ohm´s law 
and the formula for calculate the electrical power, we can find the total electrical power that we are using. First we need to find each electrical power that is using every single component, so the radio power is:
, so the radio power is: 
, then we find the pop-corn machine power as: 
and finally there are three light bulbs of 110(W) so: P=3*110(W)=330(W) and the total electrical power is the adding up every single power so that: P=330(W)+770(W)+216(W)=1316(W).
Straight linear path
Explanation:
If the universe were completely empty with just one object which is solid moving sphere through the space at a speed of 100km/s, it will move along on a straight path.
An object will continue on a straight path or at rest unless acted upon by an external force. This is the first law of newton.
- Since there is no other mass or body in the universe, it will move along in a straight line.
- Our planet and other bodies moves in parabolic path and elliptical orbits because they are attracted by the gravitational forces of other bodies.
- Any body with mass will attract other bodies and makes it move round it.
- The body with the less mass will orbit in the vicinity of the larger mass.
- But if we have just one body out there, there is no attraction from any other body, it will continue along it's straight path.
