Three states of matter is solid- when all of the molecules are packed together very tight, liquid- when there is space between the molecules and gas- when the molecules are free to move.
-hope that helps!!

A sound wave has a speed of 330m/s and a wavelength of 0.372 m. what is the frequency of the wave?
Alja [10]

Answer:

887.1Hz

Explanation:

Given parameters:

Speed of sound wave  = 330m/s

Wavelength  = 0.372m

Unknown:

Frequency  = ?

Solution:

To solve this problem, we use the expression below:

             Speed  = Frequency x wavelength

            330  = Frequency x 0.372

   Frequency  = 887.1Hz

Why are some fasteners double or triple threaded?
OLga [1]
<span>Fasteners are double or triple threaded with the idea of durability. People look for durability in a fastener and if they receive one with triple threaded or double threaded they will feel more safe and at ease knowing it has extra strength added.</span>

I need help on number 5. We need to use one of the four kinematics equations.
Gnom [1K]

ANSWER

35.02m

EXPLANATION

Parameters given:

Initial velocity, u = 26.2 m/s

When the vase reaches its maximum height, its velocity becomes 0 m/s. That is the final velocity.

We can now apply one of Newton's equations of motion to find the height:

v^2=u^2-2as

where a = g = acceleration due to gravity = 9.8 m/s²

Therefore, we have that:

\begin{gathered} 0=26.2^2-2(9.8)s \\ \Rightarrow19.6s=686.44 \\ s=\frac{686.44}{19.6} \\ s=35.02m \end{gathered}

That is the height that the vase will reach.

An automobile traveling on a straight, level road has an initial speed v when the brakes are applied. In coming to rest with a c
Molodets [167]

Answer:

4x

Explanation:

Use v^{2} = u^{2} +2as to do the question.

For first instance,

0 = v^{2} +2ax -------------------( 1 )

for second instance,

0 = (2v)^{2} +2as-----------------( 2 )

So by (1) and (2),

s = 4x
