Solve 3* +5-220t = 0

slega [8]

Answer:

t = 27.5

Explanation:

$3 + 5 -220t = 0$

Well to solve for t we need to combine like terms and seperate t.

So 3+5= 8

8 - 220t = 0

We do +220 to both sides

8 = 220t

And now we divide 220 by 8 which is 27.5

Hence, t = 27.5

How do magnetic stripes show the history of earth's magnetic field?

Mama L [17]

If i could heat a piece of iron so that it melted, and then held a magnet close to the molten iron and then let the iron cool to room temperature, you could use a microscope to look at the iron and tell that a magnet had been present during cooling. you could even tell if it was the north or south pole of the magnet that i held close to the molten iron.

Magma/lava contains a lot of molten iron so that when it erupts from a volcano and cools, the magnetic field of the earth leaves an imprint in it, just like the cooling iron from above. From this imprint we can tell the strength of the magnetic field and also which direction the north and south poles were at the time.

a motorcycle traveling on the highway at a velocity of 120 kilometre-per-hour passes a car traveling at a velocity of 90 kilomet

musickatia [10]

Answer:

The relative velocity of the motorcycle to a passenger in the car is 30 km/h

Explanation:

The question relates to the principle of relative velocity and reference frames

The given parameters are;

The velocity of the motorcycle, v₁ = 120 km/h

The velocity of the car, v₂ = 90 km/h

The relative velocity of an object X with regards to another object Y is the velocity the object X will seem to be moving with to an observer in the rest frame of object Y written as $\underset{v}{\rightarrow}_{X|Y}$ = $\underset{v}{\rightarrow}_{X}$ - $\underset{v}{\rightarrow}_{Y}$
