<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.

Analyze how friction can be both a positive and negative aspect on our lives
denpristay [2]
Positive - Friction allows us to create heat in a desperate situation, like being lost in the woods. If we didn't have friction, we would probably freeze to death.
Negative - Friction can also cause unwanted fires, such as forest fires. If friction didn't exist, we wouldn't have these.

The driver of a 2.0 × 10³ kg red car traveling on the highway at 45m/s slams on his brakes to avoid striking a second yellow car
nignag [31]

Answer:

Explanation:

a = F/m = 7500/2000 = 3.75 m/s²

v² = u² + 2as

s = (v² - u²) / 2a

s = (0² - 45²) / (2(-3.75))

s = 270 m

A stone is thrown at an angle of 30 degrees above the horizontal from the top edge of a cliff with an initial speed of 12 m/s. A
natta225 [31]

v = initial velocity of launch of the stone = 12 m/s

θ = angle of the velocity from the horizontal = 30

Consider the motion of the stone along the vertical direction taking upward direction as positive and down direction as negative.

v₀ = initial velocity along vertical direction = v Sinθ = 12 Sin30 = 6 m/s

a = acceleration of the stone = - 9.8 m/s²

t = time of travel = 4.8 s

Y = vertical displacement of stone = vertical height of the cliff = ?

using the kinematics equation

Y = v₀ t + (0.5) a t²

inserting the values

Y = 6 (4.8) + (0.5) (- 9.8) (4.8)²

Y = - 84.1 m

hence the height of the cliff comes out to be 84.1 m
