How do the parallel magnetic “stripes” near mid-ocean ridges form?

<span>When lava erupts from mid-ocean ridges, it cools rapidly into rock. As it does, it becomes magnetised permanently in the direction of the Earth's magnetic field.</span>

Answer:

When oceanic crust layer of earth pulls apart, magma erupts to the surface at the mid-ocean ridges and develops new layers of ocean floor.

Magma contains ferromagnetic minerals. These minerals align themselves in the direction of earth’s magnetic field reversing its polarity every now and then. When this magma cools down, it freezes in this alignment. In this way first strip is developed.

Later when the earth magnetic field changes its polarity again, the next strip is formed but has opposite polarity to the first strip.

Answer:

The tomato won't hit the car

Explanation:

According to the statement, the car moves at constant speed behind the truck fully loaded with tomatoes, and in the same direction. When a tomato falls from the top of the truck, it should not hit the car as the tomato falls due to the force of gravity, while horizontally has the same speed and in the same direction as the truck. So we assume that the tomato will fall to the road without touching the car.

While in a car at 4.47 meters per second a passenger drops a ball from a height of 0.70 meters above the top of a bucket how far

viktelen [127]

Answer:

1.7 m

Explanation:

$v_x$ = Velocity of ball in x direction = 4.47 m/s

$u_y$ = Velocity of ball in y direction = 0

g = Acceleration due to gravity = $9.81\ \text{m/s}^2$

t = Time taken

$s_y$ = Vertical displacement = 0.7 m

$s_y=u_yt+\dfrac{1}{2}gt^2\\\Rightarrow 0.7=0+\dfrac{1}{2}\times 9.81t^2\\\Rightarrow t=\sqrt{\dfrac{0.7\times 2}{9.81}}\\\Rightarrow t=0.38\ \text{s}$

Horizontal displacement is given by

$s_x=v_xt\\\Rightarrow s_x=4.47\times 0.38\\\Rightarrow s_x=1.7\ \text{m}$

The passenger should throw the ball 1.7 m in front of the bucket.
