Answer: frequency = 6.5 Hz

Explanation:

Given that the

Speed V = 65 m/s

Wavelength (λ) = 10m

Wave speed is the product of frequency and wavelength. That is,

V = fλ

Substitute V and (λ) into the formula to get frequency f

65 = 10f

Make f the subject of formula

f = 65/10

f = 6.5 Hz

Therefore, the frequency of this wave is 6.5 Hz?

A spring with a spring constant of k = 185.0 N / m is oriented vertically, with one end on the ground. What distance does the sp
uysha [10]

Answer:

The distance spring compresses (x) = 0.0811 m

Explanation:

Spring constant (k) = 185 N / m

mass (m) = 1.53 kg

When mass is placed upon the spring the spring force is equal to weight of the mass.

⇒ Spring force (F) = weight of object

⇒  Spring force (F) = k × x

 And weight of the object = mg

⇒ k x =  mg -----------------(1)

Put all the values in equation (1) we get

⇒ 185 × x = 1.53 × 9.81

⇒ x = 0.0811 m

This the distance spring compresses, when mass is placed upon it.

Can someone explain with steps please​
bonufazy [111]

Answer:

The speed of other projectile is 3.1m/s

Explanation:

Range of projectile is given by the equation

\mathrm{R}=\frac{\mathrm{u}^{2} \cdot \sin 2 \theta}{\mathrm{g}}

Here we have same range

Hence

\frac{\mathrm{2.5}^{2} \cdot \sin (2 \times 65)}{\mathrm{g}}=\frac{\mathrm{u}^{2} \cdot \sin (2 \times 15)}{\mathrm{g}}\\\\u^2=\frac{2.5^2\sin130}{\sin30} \\\\u=3.10m/s

compare the distance time graph for a fast-moving object with the distance time graph of a slower moving object
soldi70 [24.7K]
The slope of the distance/time graph is the speed of the moving object. 
So the graph for a fast moving object will have a greater slope than the
graph for a slower moving object has.
