Diamonds structure is defined by series of multiple covalent bonds. Given that it is made of a very strong bond, this makes some of its bulk properties relatable to this. Example its density which is larger than most of the crystalline. Another is its intensive property of its temperature, given that the diamond is hard to break down, it also has high melting point.
Answer: because she is pedalling at her maximum speed produced by the maximum force applied. At constant speed, acceleration is equal to zero.
Explanation:
Pedalling of bicycle involves application of force. The force applied produces circular motion to the tires which eventually transform into linear speed.
V = wr
Where V = linear speed
W = angular speed
r = radius.
Change in speed V will lead to acceleration or deceleration depending on increase or decrease in speed.
If she stops accelerating, then, she must have applied force that makes her pedalling at maximum speed. She is also maintaining this uniform (constant ) speed. After reaching her maximum speed.
At constant speed, acceleration = 0
Base on this explanation, even though she is still pedalling as fast as she can, which at constant speed, she will stop accelerating and her speed reaches a maximum value because she is pedalling at her applied maximum force.
Answer:
0.00712 m
Explanation:
Given:
Charge on first particle (q₁) = 75 nC =
Charge on second particle (q₂) = 75 nC =
Force (F) = 1.00 N
Separation (d) = ?
The magnitude of force is given by Coulomb's law which states that, the magnitude of force acting between two charged particles separated by a distance is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
Therefore, the magnitude of force is given as:
Where, is the coulomb's constant.
Plug in the given values and solve for 'd'. This gives,
Therefore, the distance between the charges is 0.00712 m.
Answer:
The distance of the first bright fringe is given as
The distance of the second dark fringe from the central bright fringe is given as
Explanation:
From the question we are told that
The slit separation distance is
The distance of the slit from the screen is
The wavelength is
For constructive interference to occur the distance between the two slit is mathematically represented as
Where m is the order of the fringe which has a value of 1 for first bright fringe
Substituting values
For destructive interference to occur the distance between the two slit is mathematically represented as
m = 2
so the formula to get the dark fringe is
Now substituting values
