Solution:
we know that the potential of any point is given by
v= kq/r^2............(1)
According to the question we have point charges is applied only two point so we must multiply the above equation by 2.
Then we get
V=2kq/r^2 [since charge is unity].
Hey There!
The angle of incidence increases and the angle of refraction increases.
Thank You!
Answer:
kinetic energy of the train = 2,910.6 x 10⁷ joule
Explanation:
Given:
Mass of train = 3.3 x 10⁷ kg
Speed of train = 42 m/s
Find:
kinetic energy of the train
Computation:
kinetic energy = (1/2)(m)(v²)
kinetic energy of the train = (1/2)(3.3 x 10⁷)(42²)
kinetic energy of the train = (1/2)(3.3 x 10⁷)(1,764)
kinetic energy of the train = (3.3 x 10⁷)(882)
kinetic energy of the train = 2,910.6 x 10⁷ joule
field is force at a distnce = falling under grav ... contact is force at point of contact
Bread is considered to be a heterogeneous mixture. It is a heterogeneous mixture because all of the components that are used to make the bread are physically separate.
