Transformers only work with AC.
If you put DC into a transformer, all that comes out is smoke.
(a)
1. Height of cube =9cm
mass of cube= 3645 g
volume= length ×breadth× height
as cubic volume so length breadth and heights are same so
volume =height ×height ×height
V =9cm×9cm×9cm= 729cm³
density =mass/ volume
density =3645g/729cm³
density= 5g/cm³
2. AS DENSITY = mass/volume
volume =mass/ desity
volume= 13.558g/(0.089g/l)
volume= 0.152L³
Answer:
The initial acceleration is 0,221 m/s^2.

Explanation:
Let assume that pole vaulter begins running at a height of zero. The pole vaulter is modelled after the Principle of Energy Conservation:
The expression is simplified and final height is cleared within the equation:
![h_{B} = \frac{[(11\,\frac{m}{s} )^{2}-(1.3\,\frac{m}{s} )^{2}]}{2\cdot (9.807\,\frac{m}{s^{2}} )}](https://tex.z-dn.net/?f=h_%7BB%7D%20%3D%20%5Cfrac%7B%5B%2811%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D-%281.3%5C%2C%5Cfrac%7Bm%7D%7Bs%7D%20%29%5E%7B2%7D%5D%7D%7B2%5Ccdot%20%289.807%5C%2C%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%29%7D)
Answer:
Latent heat, along with birds, ride those rising columns of air. This brings up a third and the ultimate mechanism by which the Earth's heat escapes into space, which is electromagnetic radiation. Every object, including the Earth's surface, absorbs and radiates heat electromagnetically
