As it is given that Bulk modulus and density related to velocity of sound
![v = \sqrt{\frac{B}{\rho}}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7BB%7D%7B%5Crho%7D%7D)
by rearranging the equation we can say
![B = \rho * v^2](https://tex.z-dn.net/?f=B%20%3D%20%5Crho%20%2A%20v%5E2)
now we need to find the SI unit of Bulk modulus here
we can find it by plug in the units of density and speed here
![B = \frac{kg}{m^3} * (\frac{m}{s})^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7Bkg%7D%7Bm%5E3%7D%20%2A%20%28%5Cfrac%7Bm%7D%7Bs%7D%29%5E2)
so SI unit will be
![B = \frac{kg}{m* s^2}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7Bkg%7D%7Bm%2A%20s%5E2%7D)
SO above is the SI unit of bulk Modulus
Answer:We are usually not aware of the electric force acting between two everyday objects because most everyday objects have as many plus charges as minus charges. Option A
Explanation:An electric force is exerted between any two charged objects( either positive or negative). Objects with the same charge will repel each other, and objects with opposite charge will attract each other. The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. Electric charges are generated all around us due to different surfaces bearing different types of charges. We are usually not aware of it because the quantity of positive charges equals the number of negative charges.
Answer:
Explanation:
As it moves along, the paper is given a strong negative electrical charge by another corona wire. When the paper moves near the drum, its negative charge attracts the positively charged toner particles away from the drum.
Answer:
15: Animals are able to detect the first of an earthquake's seismic waves—the P-wave, or pressure wave, that arrives in advance of the S-wave, or secondary, shaking wave. This likely explains why animals have been seen snapping to attention, acting confused or running right before the ground starts to shake.
16: No, it is not even remotely true. Microwaves cook food from the outside in, just like a regular oven. In fact, most of the cooking on the inside of the food, depending on its thickness, is done by heat conduction from the outside surfaces inwards, as the microwaves do not actually penetrate that far into the food.
