Sense an ion is an atom does it have a negative charge?

1 answer:

4 0

Ions are the name for atoms that have gained or lost one or more electrons, leaving them with a net charge. For atoms that lose an electron, they gain a positive charge and become cations. For atoms that gain an electron, they take on a net negative charge and become anions.

) A 1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. What is the magnitude of the f

Yuri [45]

The frictional force required is 9000 N

Explanation:

In order to keep the car in the turn in circular motion without sliding, the frictional force must provide the centripetal force necessary for the circular motion.

Therefore, we can write:

$F_f = m \frac{v^2}{r}$

where the term on the left is the frictional force while the term on the right is the centripetal force, and where:

m is the mass of the car

v is its speed

r is the radius of the curve

For the car in this turn, we have

m = 1000 kg

v = 30 m/s

$r=\frac{0.20 km}{2}=0.10 km = 100 m$ (since the diameter is 0.20 km, the radius is half that value)

And substituting, we find

$F_f = (1000) \frac{30^2}{100}=9000 N$

The separation in time between the arrival of primary and secondary waves is

Gre4nikov [31]

The separation in time between the arrival of primary and secondary wave is called LAG TIME.
The time difference between the arrival of primary wave and secondary wave in a seismogram is called lag time. The primary wave always travels faster than the secondary wave, thus the difference between the two can be obtained by estimating the difference between the arrival time of the two waves/.
