Answer:speed of slower cyclist is 5 mph

Explanation:

Given

Distance between two cyclist is 50 miles

One cycle is 4 times fast as other

Speed of slower cyclist is r miles per hour

speed of faster cyclist is 4 r

they meet after t=2 hr

Distance traveled by fast cyclist is x=2\times 4r

Distance traveled by slower cyclist is y=2\times r

x+y=50

2\times 4r+2\times r=50

8r+2r=50

10r=50

r=5 mph

4 r=20 mph

speed of slower cyclist is 5 miles per hour

Solve the following problem showing all work, the formula, and correct units.
Temka [501]

5g/cm³

it is not iron.

Explanation:

Given parameters:

Density of iron = 7.874g/cm³

Mass of metal = 2000g

Volume of metal = 400cm³

Unknown:

Density of bar = ?

Is it iron = ?

Solution:

The density of a substance is its mass per unit area. Every substance have an intensive density value that typifies them all.

The density of water and other substances are the same if they maintain their level of pureness.

   Density = \frac{mass }{volume}

Density of metal bar = \frac{2000}{400} = 5g/cm³

Since this value is not the same as the given density of iron, it is not iron.

When you drop a strong magnet through the center of a copper pipe, what happens to the copper piper and the magnet?
Sedbober [7]
Copper is; unlike iron and steel; not ferromagnetic, but diamagnetic. This means that induced magnetic fields in copper will counter the applied force.

When you drop a strong magnet through a copper pipe, the moving magnetic field will induce currents (Lenz’ Law). These currents will now induce their own magnetic field. This magnetic field counters the falling magnetic.

Result: the magnet will fall way slower than if it was falling through a plastic pipe.
