Transformers are bots that "transform" into cars and giant mega robots. Im personally not a big fan of transformers but it is called transformers because it can transform into other non-living objects. <span />
Answer:
Velocity is a vector (it has magnitude and direction), so the overall velocity of an object can be found with vector addition of the x and y components: v2 = vx2 + vy2. The units to express the horizontal and vertical distances are meters (m).
Answer:
Explanation:
Newton's ring equation relates the initial and final diameter of the ring, to the index of refraction of the air and the index of refraction of the liquid between the lens and the plates, as follows:
Solving for :
Recall that the refractive index of the air is 1. So, replacing the given diameters:
india became more isolated due to the lack of resources
You can look at magnesium, it can react with oxygen to form oxides. (chemical) it is malleable and a solid at room temperature. (physical)
to measure its density, the mass and volume can be worked out and from this density too. look up the equation, it is quite easy :)
physical changes -- it can be melted, and oxidized <span />
