We know follwing formula
F=a*m
where F is RESULTANT force, a is acceleration and m is mass. We can transform that formula to obtain a, so
F=a*m /:m divide both sides by m
Now we have to calculate resultant force acting.
We know that Dale and Alex push on opposite direction so we have to put minus in front on one of the forces and add it.
40+(-32)=40-32=8 [N] - resultant force acting on the couch
Now we have all necessary date, we can substitute.
a=
- its the result
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Answer:
a. True
Explanation:
Metals are amazing, and they are all around us. You can probably easily identify them by their shiny surfaces and tinny sound when you tap them.
Generally, metals are mainly hard, shiny, and can be hammered into thin sheets. Also, another property of a metal is that, it is a good conductor of heat and even electricity because there valence (outer) electrons are delocalized. Some examples of chemical elements that are metals are iron, gold, sodium, silver, copper etc.
A) A fault occurs when stresses in the crust cause land on one side of the fracture to move to relation to the other side.
