To solve this problem we will apply the second law of kinematics that describes the position as a function of speed, time and its acceleration, as
Here,
= Initial velocity
t = Time
a = Acceleration
Our values are,
Replacing we have that
From this expression we could determine the position traveled, without considering that the given speed is the same assumed in the term of acceleration. Under this consideration we would have to v = 4m / s
Answer:
The answer is gravitational force
Explanation:
Answer:
the force on an object is equal to its mass times its acceleration.
Explanation:
the more heavier the object (lawn mower) the more time it will take to cut the grass due to that the tv show will be gone
As the engine heats up, a natural circulation starts, as coolant rises through the engine block by convection. It passes through the top hose, and into the radiator. Inside the radiator, heat is removed from the coolant as it falls from the top to the bottom.
Hope this helps!
Answer:
Electromagnet A, which uses a piece of iron as its metal core will produce the stronger magnetic field
This is because of the ferromagnetic properties of iron
Silver is not attracted to magnets
Explanation:
An electromagnet with an iron core produces a stronger magnetic effect, because ferromagnetic materials have the effect of concentrating the magnetic flux.
An electromagnet with a gold, silver or titanium core would be perfectly functional, as would one with a core made out of wood, or a human finger, that is to say they don't produce magnetic effects. Silver isn't noticeably magnetic. In fact, only iron, nickel, cobalt, gadolinium, neodymium and samarium are magnetic in our everyday lives. An ingot of pure silver isn't attracted to a magnet.
