3. What is the temperature if a 545-Hz sound wave has a wavelength of 0.651 m

Physics
1 answer:
KATRIN_1 [288]3 years ago
7 0

Answer:

19.33°C

Explanation:

To find the value of T you use the following formula:

v=343+0.61T

v: speed of sound

To calculate v you use:

v=\lambda f

λ: wavelength = 0.651m

f:  = 545Hz

by replacing :

v=(0.651m)(545s^{-1})=354.79m/s

Finally, by replacing in the first formula you obtain:

354.79=343+0.61T\\\\T=19.33\°C

T = 19.33°C

Two trains of length 90m and120m<br>​
Alenkasestr [34]

Answer:Train A is 90 m long and running at 72 km/h.

Train B is 120 m long and running at 36 km/h.

When the trains are running in opposite directions, their relative speed gets added: 72+36 = 108 km/h.

The total length of A and B = 90+120 = 210 m

So the time taken to cross each other = 210 m*60*60/108*1000m

= 7 seconds

A. Fill in the blanks in the following paragraph to correctly identify some
amid [387]

Answer:

1.) Liquid

2.) Low

3.) Molecular

4.) Surface tension

5.) Solvent

Explanation:

Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does

not experience large temperature changes because liquid water has a

LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water

molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can

dissolve many different substances.

Two identical soccer balls are rolled toward each other. What will be true after they collide headon? (2 points)
elixir [45]

Complete Question:

Two identical soccer balls are rolled toward each other. What will be true after they collide headon?

Group of answer choices.

A. they will both stop rolling immediately after they collide head–on.

B. One ball will stop rolling and the other will roll backward at a slower speed.

C. They will both roll back at the same speed they had before the collision

D.They will both roll to the side at a faster speed after the collision

Answer:

C. They will both roll back at the same speed they had before the collision

Explanation:

Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.

This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.

In this scenario, two identical soccer balls are rolled toward each other. Thus, after they collide headon, they will both roll back at the same speed they had before the collision in accordance with Newton’s Third Law of Motion.

Additionally, The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.

This ultimately implies that, if the two identical soccer balls exert forces only on each other, their total momentum is conserved
