Physics
1 answer:
andre [41]3 years ago

Answer:

6.98 × 10^(14) Hz

Explanation:

wavelength in air; λ_o = 430nm = 430 × 10^(-9) m

Speed of violet light in the prism; v = 2 × 10^(8) m/s

Speed of light in air = 3 × 10^(8) m/s

To get the frequency, we will use the relationship;

f = c/λ_o

Plugging in the relevant values;

f = (3 × 10^(8))/(430 × 10^(-9))

f = 6.98 × 10^(14) Hz

If a rocket-powered sled is accelerated to a speed of 440 m/s in 2.20 seconds, then what is the acceleration?
Svetlanka [38]

Answer:

200 m/s^2

Explanation:

The acceleration of an object is calculated as

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken for the velocity to change from u to v

For the rocket in this problem:

u = 0 (it starts from rest)

v = 440 m/s is the final velocity

t = 2.20 is the time taken

Substituting,

a=\frac{440-0}{2.20}=200 m/s^2

Josh starts at a position of x=0 meters at the left side of the front of the classroom. Over the course of the class he walks ba
Aneli [31]
Answer:
180 meters

Explanation:
Josh walks 6 meters to the right and the 6 meters back. This means that in one time, Josh walks a total distance of 6+6 = 12 meters
Now, we are given that Josh walks this same distance 15 times.
Therefore, we will multiply this distance by 15 to get the total distance that he walks as follows:
Total distance = 12*15 = 180 meters

Based on the above calculations, Josh walks 180 meters over the course of the class

Hope this helps :)

Which component is used to change alternating current to direct current? a diode an integrated circuit a transistor a capacitor
lesantik [10]

As we know that equivalent resistance of a capacitor for an AC circuit is given as

X_c = \frac{1}{\omega C}

so here for an AC circuit capacitor will provide less resistance to AC component of the current

While for DC as we know it has ZERO frequency

so we will have large resistance

so here we will have to use capacitor as a filter circuit which will separate AC component of current from the DC current

So correct answer will be

CAPACITOR
