What is the difference between prime numbers and odd numbers? Basically, odd numbers are numbers that can't be divided by 2, for example, 1,3,5,7,9,11 etc If you divide any of them by 2, the result would be a fraction and not an integer. like 7/2=3.5, 11/2=5.5 A prime number is a number that can only be divided by 1 or itself to result in an integer, for example, 2,3,5,7,11,13,17,19. For example, 15 is an odd number but it can't be a prime number because it can be divided by 3, 15/3=5, also 21/3=7, so 21 can't be a prime number.

Evaluate 35-18÷3x2= according to the order of operations, division and multiplication are performed first from left to right. So, we will start by (18÷3=6), then (35-6x2= ) Then we will start with the multiplication, 6x2=12, then 35-12=23

What's electrical induction? It's the phenomenon in which electric current can be induced in a conductor when it cuts magnetic field lines. Any electric current passing through a conductor forms a magnetic field moving around it. As energy can neither be created nor destroyed, electric current can be induced in a conductor when it cuts the magnetic field lines of a magnetic field.

Define the inertia and the inertial force Inertia is the tendency of anybody to keep its direction of motion. It can be noticed when an external force acts on a moving body opposite to its direction. For example, a passenger in a vehicle will move forward - in the direction of motion of the vehicle - when the brakes are pressed suddenly. One of the usages of seat belts is to protect the passengers from collision with the interior of the vehicle in case of sudden braking. Inertial force is a force that resists the change of the velocity of a moving body.
