knowing the age of a grandmother because she was a kid during the Great Depression
Explanation:
The best example for relative age is simply knowing the age of a grandmother because she was a kid during the Great Depression. Relative age is usually based on the occurrence of a popular and world wide event. It is not an absolute age that gives numerical and quantitative values to age.
- The reference here is the Great Depression
- The Grandmother was kid during this period in time.
- We can use this knowledge to infer her age.
- Since she was a kid at that point, her current age would how far back the depression was and an estimate of her age at that time.

It is highly helpful to know that the mechanical advantage (M.A.) of Class two levers is usually greater than one. It is because the overall length of the Effort Arm is higher than the overall length of Load Arm. It is easily known by MA is effort arm/load arm.
!! ⬇️
The mechanical advantage of a lever of the second order is always greater than one because its effort arm is always longer than the load arm i.e. Effort arm > Load arm.
Second class lever has mechanical advantage always more than one as load is in between fulcrum and effort making the effort arm longer than the load arm.
First Class Lever -- the effort and the load on either side of the fulcrum. Some examples would be a crowbar or a seesaw. The effort is only less than the load if the load is closer to the fulcrum. The lever then acts as a force magnifier and the mechanical advantage is greater than one.
This would be true!
When you subtract a positive number, it goes to the left of the number line. When you subtract a negative number, it goes to the left of the number line.
The thing that confuses most people is that the first number (when negative) continues to increase as a negative. It follows the same process, just different signs.
I hope this helps!

Explanation:
i think you have to find the velocity by using its wight times the gravity of the earth times the distance it fell?
look in google for a formula the use these sign, w and g ,d
Answer:
if your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts
