All the formulas of physical acceleration are those for time and velocity
Displacement formula x = v0t + 1 / 2at square velocity formula v = V0 + at velocity displacement formula V square - V0 square = 2aX high one physics formula summary 1. Motion of particle (1) ---- linear motion 1) uniform linear motion 1. Average velocity V flat = s / T (definition formula) 2. Useful inference VT ^ 2 – VO ^ 2 = 2As 3
In uniform linear motion, the following statement about the formula v = st is correct ()
A. Speed V is directly proportional to distance S. B. the size of speed V has nothing to do with distance s and time T. C. when speed V is constant, distance s is inversely proportional to time T. D. speed V is inversely proportional to time t
In uniform linear motion, speed is a fixed value, that is, the ratio of distance to time is a fixed value, that is, the distance is proportional to time
The following statement is correct ()
A. The greater the velocity V, the greater the distance S. B. the greater the velocity V, the greater the time T. C. the velocity V is directly proportional to the distance s and inversely proportional to the time T. D. the velocity V is determined by St, but has nothing to do with the size of S and t
In uniform linear motion, speed is a fixed value, that is, the ratio of distance to time is a fixed value, which has nothing to do with the distance the object passes and the time of motion
Excuse me?
What are the laws and formulas in the second semester of junior high school
Ohm's Law: I = u / r u = IR r = u / I
Calculated electric energy: P = w / T
Measurement of electric power: P = UI = w / T = u ^ 2 / r = I ^ 2R
Joule's Law: q = I ^ 2rt [when q = w, q = w = Pt = uit = u ^ 2 / RT = I ^ 2rt]
Electromagnetic wave: C = λ f [C: wave speed, λ: wavelength, F: frequency]
What do the symbols∧and∨in mathematical formula mean?
For example: in v = (4 / 3) π R ^ 3^
Λ is the symbol of logical connectives, representing Chinese characters
Another representative or word;
That means power
For example, X & # 178; = x ^ 2, some people can't find a small 2
∂ the meaning of symbol in mathematical formula
Partial derivative. Find the partial derivative of a variable to a function in multivariate function

What are the functions of colons?
The colon can replace the division sign to show the relation of ratio
How to understand the symbols in architectural drawings?
I can't understand the diagram
I'll send you an atlas. You can have a look at it first
Detailed meaning of symmetrical symbols in construction drawings
It is the symmetrical symbol of the construction drawing drawn in CAD, as shown in the following figure:
(represented by two groups of parallel lines, the distance between the parallel lines is 2 ~ 3mm, the length of both sides of the parallel line is equal, and the total length is 6 ~ 10mm.)
The length of the two sides of the parallel line is equal, and the total length is 6 ~ 10 mm?
Be specific
It should be like this
What are the meanings of all symbols and letters on the drawing?
