The sound wave is 1.0 meters

bagirrra123 [75]3 years ago
7 0

Answer:

The long of the wave is 0.664 m

Explanation:

f= \frac{1}{T} \\  Hz= s^{-1} \\ T=\frac{1}{512 Hz}= 1.953125 x10^{-3} s

The wave formula is:

V= \frac{x}{T} , x= distance Meters

x= V*T= 340 \frac{m}{s} * 1.953125 x10^{-3} s = 0.664 m

x= 0.664 m

Change the speed 0.200cm/s to units of kilometers per year .
salantis [7]
0.200cm= 0.002km

0.002*60=0.12km/min

0.12*60=7.2km/h

7.2*24=172.8km/day

172.8*365=63072km/year

Consider the program below:public class Test{ public static void main(String[] args) {Int[] a;a = new int[10];for(int i = 0; i &
ivolga24 [154]

Answer:

c. 65

Explanation:

The output is 65.

An array of length 10 is created first. Then, the first for-loop fill the array with different values; The array element now become: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11. The array element are generated using the equation a[i] = i + 2; so when i is 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. i must be less than the array length (10).

a[0] = 0 + 2 = 2

a[1] = 1 + 2 = 3

a[2] = 2 + 2 = 4

a[3] = 3 + 2 = 5

a[4] = 4 + 2 = 6

a[5] = 5 + 2 = 7

a[6] = 6 + 2 = 8

a[7] = 7 + 2 = 9

a[8] = 8 + 2 = 10

a[9] = 9 + 2 = 11

result variable is declared and initialized to 0.

The second for-loop goes through the array and add individual element to result.

How many of our solar system's large moons orbit their planets in the same direction as their planet rotates?
poizon [28]

There are 171 moons, or natural satellites, orbiting the planets in our solar system; Earth, Mars, Jupiter, Saturn, Uranus, and Neptune have 1, 2, 66, 62, 27, and 13 moons, respectively. The following is a list of some of the major planetary moons, including those of the dwarf planet Pluto.

Out of them, Most of the large moons in the Solar System have prograde orbits. This means that they orbit their planet in the same direction as the planet is rotating.

Why do all the planets orbit in the same direction?

The same reason (almost) all of them rotate in the same direction: because of the conservation of angular momentum. Before a star and its planets exist, there's just a cloud of disorganized gas and small molecules. The Solar System formed from such a cloud around 4.6 billion years ago.
