Answer:
A.
Explanation:
In all actuality. The car may not be fully moving but since it's on a hill and the earth moves it makes the most sense. Also since the car is at a slope by the law of motion what goes up must come down so the car is in fact moving.
Answer:
hello your question is incomplete attached below is the missing parts and the detailed solution of the problem
answer : ( D )
Explanation:
The force on the top left charge from the bottom left can be determined applying the equations/expression as represented in the detailed solution
option D was chosen because it accurately represents the force on the top left charge( positive y axis ) from the bottom left
In the circular motion of the hammer, the centripetal force is given by
where m is the mass of the hammer, v its tangential speed and r is the distance from the center of the motion, i.e. the length of the hammer.
Using the data of the problem, we find:
1. Curium
2. xenon
3.the element with valance electron 4 and 2 is Tin and lead
4. Nickel . if when n=3 , the number of electrons is 18 , then the total number of electrons will be 28 ; because there will be 2 electrons in n=1 and 8 electrons when n=2 using the equation .Thus atomic number will be 28. The element with atomic number 28 is Nickel
5. Deuterium .Its an isotope of hydrogen. it has only one neutron
Answer:
Uniform motion is a type of motion that is characterized as the motion of an object wherein the object moves in a straight line and its velocity remains unchanged along that line, regardless of the duration of time, as it occupies equal distances at equal time interval and Non-uniform motion is described as the motion of an object wherein the object moves at different speeds and does not cover the same distance at equal time intervals, regardless of the duration of the time interval.
