Answer: Option (A) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.
And, when gas particles move slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.
Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
It depends on two factors height and mass
Answer:
A point on the outside rim will travel 157.2 meters during 30 seconds of rotation.
Explanation:
We can find the distance with the following equation since the acceleration is cero (the disk rotates at a constant rate):

Where:
v: is the tangential speed of the disk
t: is the time = 30 s
The tangential speed can be found as follows:

Where:
ω: is the angular speed = 100 rpm
r: is the radius = 50 cm = 0.50 m
Now, the distance traveled by the disk is:

Therefore, a point on the outside rim will travel 157.2 meters during 30 seconds of rotation.

Answer:
The reulting electric field at x = 4.0 and y = 0.0 from the dipole is 0.5612 N/C
Solution:
As per the question:
Charges of the dipole, q = 
Separation distance between the charges, d = 0.0010 m
Separation distance between the center and the charge, d' = 
x = 4.0 m
y = 0.0 m
Now,
The electric field due to the positive charge on the right of the origin:
E = 
where
k = Coulomb's constant = 
Now,
E = 
Similarly, electric field due to the negative charge:
E' = 
E' = 
Thus
