Answer:
a
The number of radians turned by the wheel in 2s is
b
The angular acceleration is
Explanation:
The angular velocity is given as
Now generally the integral of angular velocity gives angular displacement
So integrating the equation of angular velocity through the limit 0 to 2 will gives us the angular displacement for 2 sec
This is mathematically evaluated as
Now generally the derivative of angular velocity gives angular acceleration
So the value of the derivative of angular velocity equation at t= 2 gives us the angular acceleration
This is mathematically evaluated as
so at t=2
Answer:
1) Addition of a catalyst
2) To change the reaction rate of slope B to look like slope A, simply add a catalyst to speed up the rate of reaction, giving you a higher amount of products in a shorter amount of time (line A)
Explanation:
1 and 2)Two things can alter the rate of a reaction, either the addition of a catylist which will not alter the composition of the products or reactants, but will accelerate the reaction time, or an increase in temperature will also increase the rate at which a reaction will occur.
You could choose temperature also and have the same result, it's your choice both are correct, but catalyst is the easiest.
Answer:
E = 12.25 x 10³ N/C = 12.25 KN/C
Explanation:
In order to balance the weight of the object the electrostatic force due to the electric field must be equal to the weight of the body or charge. Therefore,
Electrostatic Force = Weight
E q = mg
where,
E = Electric Field = ?
m = Mass of the Charge = 5 x 10⁻³ kg
g = acceleration due to gravity = 9.8 m/s²
q = magnitude of charge = 4 μC = 4 x 10⁻⁶ C
Therefore,
E(4 x 10⁻⁶ C) = (5 x 10⁻³ kg)(9.8 m/s²)
E = 0.049 N/4 x 10⁻⁶ C
<u>E = 12.25 x 10³ N/C = 12.25 KN/C</u>
Answer:
Learning about the salary, education and job market of a particular career.
so your answer is option E
Hope this helps
Have a great day (:
Explanation:
According to the research, the correct option is A way of discovering and learning about the world. It is the statement that best explains science.
<h3>What is science?</h3>
It is a set of knowledge that can be organized on a structure and helps us to answer phenomena or questions about the world.
In this sense, this set of organized knowledge is obtained from the observation of natural phenomena and the systematic and reasoned study of nature.
Therefore, we can conclude that according to the research, the correct option is A way of discovering and learning about the world. It is the statement that best explains science.
