A metal rod of length (L) moves with velocity (v), perpendicular to its length, in a magnetic field B, which is perpendicular to
Alborosie

Explanation:

If a metal rod of length L moves with velocity v is moving perpendicular to its length, in a magnetic field B, the induced emf is given by :

\epsilon=Blv

The electric field in the conductor is given by :

E=\dfrac{\epsilon}{l}\\\\E=\dfrac{Blv}{l}\\\\E=Bv

It is clear that the electric field is independent of the length of the rod. If the length of the rod is doubled, the electric field in the rod remains the same.

What is a gravitational field and how its strength be measured
Yakvenalex [24]
A gravitational field is the field generated by a massive body, that extends into the entire space. Every object with mass m experiences a force F when immersed in a gravitational field. The intensity of the force is equal to
F= \frac{GM}{r^2}  m
where G=6.67 \cdot 10^{-11} m^3 Kg^{-1} s^{-2} is the gravitational  constant, M is the mass of the source of the field (e.g. the mass of a planet), and r is the distance between the object and the source of the field. The force is always attractive. 

A possible way to measure the intensity of a gravitational field is by measuring the acceleration a of the object immersed in this field. In fact, for Newton's second law we have:
F=ma
but since 
F= \frac{GM}{r^2} m
we can write
a =  \frac{GM}{r^2}
Therefore, by measuring the acceleration of the object, we also measure the intensity of the field.

Impact of Synthetic Materials Discussion
Wittaler [7]

With the below stated fact  I think that  the pros of using synthetic materials outweighs the cons.

Before we answer the question

If the pros of using synthetic materials outweigh the cons or otherwise, let us first establish the what a synthetic material is and its pros and cons

Synthetic material

Synthetic material is a material in which a substances are changed chemically to produce a material with different characteristics.

Types of Synthetic material

  •    Plastic bag  
  •    Synthetic fiber/cloth  
  •    Artificial sweetener
  •    Synthetic fuel      
  •    Aspirin

Pros of Synthetic materials

  • They are used in construction because of there strong bonding
  • They can be molded
  • They can be colored into any shade
  • They are cheap

Cons of Synthetic materials

  • Sometimes none degradable
  • They do not absorb water.
  • They are highly flammable
  • Melts easily

In conclusion

Although Synthetic materials has so very pressing disadvantages to human kind it is unrefusable the importance of Synthetic materials to the day to day live of all humans

Therefore, I think that  the pros of using synthetic materials outweighs the cons

Josh is refilling his pool with clean water. How many gallons of water will it take if the pool is 50m by 25m by 1.5m?
horsena [70]

Answer:

V = 493421.05 [gal]

Explanation:

This is a problem that consists of handling units, we can calculate by first-hand the volume, then convert units from cubic meters to gallons.

V = 50 * 25 * 1.5

V = 1875 [m^3]

Now we need to convert units, using the proper conversion factor.

1875[m^3]*\frac{1000lt}{1m^3} *\frac{1gal}{3.8lt} \\493421.05[gal]
