Answers
Step-by-step explanation:
force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force.
Frictional Force: Gravitational Force
Tension Force: Electrical Force
Normal Force: Magnetic Force
Answer:
Any number that gives a remainder of 2 when being divided by 9 also gives a remainder of 2 when being divided by 3 so the question simplifies to how many 2-digit number give remainder of 2 when divided by 3.
There are exactly 90 numbers between 10 and 99. And since it's a multiplication of 3 then we have 30 numbers with each remainder.
You can also verify that if in an arithmetic sequence the first element is 11 and is 98 and the step is 3 then n=30.
