The motivation behind why the vertical stature of the stairs is the main thing measured is that it uncovers to us how much gravity is up against the individual and their weight, so we require this data to decide how much vitality and power we have to get up the stairs.
1. The speed is at a constant rate same with the acceleration and velocity
2. When there getting close to the top there speed, acceleration, and velocity all start to decrease
3. The speed and acceleration and velocity all on the way down drastically increase number
hope I helped
Explanation
A phase change is when matter changes to from one state (solid, liquid, gas, plasma) to another.
All phase changes require a gain or a loss of heat energy. The energy change allows the particles to have a new arrangement, thereby creating a new phase. These phase changes can only happen at certain fixed temperatures for each type of substance.
Answer:
Here's what I think,
A_Trigonometric_ratio (whatever)
The general form of sin/cos/tan(angle).
So here as in the general form the "whatever" is always an "angle" input which (may sound a bit unfair but) is a dimensionless quantity.
As mentioned in your question,
F= Asin(Bt) + C cos (Dy)
Dimentions of these terms will be same (by homogenity of dimensions).
So what we gotta do here is make Bt and Dy dimensionless for this whole equation to work.
According to your question t is time,
So to make Bt dimensionless,
B must be equal to inverse of time i.e T^(-1)
Using the same process on Dy, gives inverse of length i.e L^(-1)
So,
B= M^(0)L^(0)T^(-1)
D = M^(0)L^(-1)T^(0)
The dimension of D/B then will be M^(0)L^(-1)T^(1)
