Because of barriers and obstructions, you can see only a tiny fraction of a standing wave on a string. You do not know, for inst

ance, how long the string is. All you know is that the speed of waves on the string is 100 m/s and that the distance is 10 cm. Can you determine the frequency of the standing wave? 1. Sure, the frequency is 1000 Hz. 2. Sure, the frequency is 500 Hz.

Answer:

500 Hz

Explanation:

Given that,

speed of waves on the string is 100 m/s

distance is 10 cm

so given v is 100 m/s and L is 10 cm

frequency = speed (wave on string) / 2L

so the frequency is 100/2*10*10^-2m

= 1000/2

=500 Hz  

so the answer is 500 Hz

frequency = speed (wave on string) / 2L

so given v is 100 m/s and L is 10 cm  

so the frequency is 100/2*10*10^-2m

= 1000/2

=500 Hz  

so the answer is 500 Hz

Answer:

(1) Sure, the frequency is 1000 Hz.

Explanation:

Frequency = wave speed ÷ wave distance

wave speed = 100 m/s

wave distance = 10 cm = 10/100 = 0.1 m

Frequency = 100 ÷ 0.1 = 1000 Hz

Why does it take mars over 500 days to orbit the sun?
kakasveta [241]

Answer:

Mar's orbital path is more than that of Earth, thus it takes more number of days to orbit around the sun.

Explanation:

Mars takes over 500 days to orbit all the way around the sun than Earth because its distance from the sun (228 million kilometers) is greater than that of Earth (150 million kilometers) which takes it 365 days.

Planets that orbit closer to the sun take shorter time to orbit around the sun because the cover a shorter orbital distance and orbit faster than those planets further from the sun.

<u>For example</u>

Using Earth's distance from the sun, 150 million kilometers and the number of days taken to orbits the sun ,365 days and the distance Mars is from the Earth, 228 million kilometers, you can approximate the time Mar takes to orbit the sun as:

Earth 150 million kilometers  = 365 days

Mars  228 million kilometers= ?

Cross product ; (228 *365) /150 =555 -----(a value closer to that in the question)

A 15-lb block B starts from rest and slides on the 25-lb wedge A, which is supported by a horizontal surface. Neglecting frictio
xxTIMURxx [149]

The angle of the wedge is 30°.

Answer:

5.88 ft/s

Explanation:

a) The block will slide down due to it's weight.

initial velocity u= 0

final velocity, v

acceleration, a = g sin 30° = 32 ft/s²× sin 30° = 16 ft/s²

Sliding displacement, s = 3ft

Use third equation of motion:

v^2-u^2 = 2as

substitute the values and solve for v

v^2-0 = 2\times 16 \times 3 =96 ft^2/s^2\\v = 9.8 ft/s

b) Use conservation of momentum:

Initial momentum of the system  = 0

final momentum = (15) ( 9.8)+ (25)(v')

v' = 5.88 ft/s
