Answer:
(a) E = 1.25×10⁶ V/m
(b) v = 83.8×10⁶ m/s
Explanation:
Please see attachment below.
qV = electric potential energy of the electron. This is the energy converted into the kinetic energy of the motion of the electron through the plates. Kinetic energy is 1/2×mv². Where m = mass of electron = 9.11×10-³¹ kg.
q = 1.6×10-¹⁹ C.
So qV = 1/2mv² so rearranging and substituting the given quantities give the speed of the electrons.
I think it might be immortal? Not sure what is your point
The size of the field 'decreases'. Imagine zooming in on your TV so that your face is pressed up against the screen. you can see the individual pixels but you cannot see the whole picture because the sizer of your 'field of view' has shrunk.
Answer:
Explanation:
Given that,
Height of the inclined plane, h = 2.02 m
Final velocity of the object, v = 5.72 m/s
To find,
The moment of inertia of the object.
Solution,
As the object rolls down the inclined plane, its gravitational potential energy gets converted to the kinetic energy along with rotational kinetic energy.
Since,
On rearranging the above equation and finding the value of I as :
So, the moment of inertia of an object that rolls without slipping down is
Answer:
Explanation:
The five steps used for solving design problems are:
1. Define the problem
2. Gather pertinent information
3. Generate multiple solutions
4. Analyze and select a solution
5. Test and implement the solution
1. The first step of engineering design is to identify the problem.
2. The inputs to this activity include the research the problem, perhaps supplemented with evaluate possible solutions, both produced during product design.
3. In terms of the software life cycle, engineering design occurs during the protype creation and selection phase.
4. A good way to engage the problem during this activity is to test and evaluate the protype, which produces the main outputs of this activity.
