Dao makes a table to identify the variables used in the equations for centripetal acceleration. A 2 column 5 rows. The first col
2 answers:
Answer:
Column X. Tangential Speed
Column Y. radius
Explanation:
The equation for centripetal acceleration is
= v² / r
Where v is the tangential velocity of the body and the radius of curvature.
To analyze this equation you must place the tangential velocity in one column and in the other the turning radius
Let's check the answers
Column X. Tangential Speed
Column Y. radius
This is the correct answer.

Answer:
1 angstrom = 0.1nm
5000 angstrom = 5000/1 × 0.1nm
<h3>= 500nm</h3>5000 angstrom = 5000 × 1 × 10^-10
<h3>= 5 × 10^-7 m</h3>Hope this helps you
To solve this problem it is necessary to apply the concepts related to thermal stress. Said stress is defined as the amount of deformation caused by the change in temperature, based on the parameters of the coefficient of thermal expansion of the material, Young's module and the Area or area of the area.
Where
A = Cross-sectional Area
Y = Young's modulus
= Coefficient of linear expansion for steel
= Temperature Raise
Our values are given as,
Replacing we have,
Therefore the size of the force developing inside the steel rod when its temperature is raised by 37K is 38526.1N
6m at 0.9 radian means 6m at
Since positive angles are counter clockwise
6m at can be written as 6*cos
i+6*sin
j = 3.73i+4.70j
5m at can be written as 5*cos
i+5*sin
j = 1.294i-4.83j
4m at 1.2 radian means 4m at
4m at can be written as 4*cos
i+4*sin
j = 1.45i+3.73j
6m at can be written as 6*cos
i+6*sin
j = -5.20i-3j
a) So sum of the vector = 1.274i+0.6j
b) Magnitude =
c) Angle,
