What is the model size to actual size

Murljashka [212]

Answer:

You have to divide your real measurement to the model. For example, if your real measurement is 5m and your model is 20cm, divide 5/20 =1/4 and that means the ratio would be 1:4.

Wave 1 displaces according the function f(θ)= 2sin θ+1. Wave 2 displaces according to the function f(θ)= 3sin θ+.5. At what angl

r-ruslan [8.4K]

Answer:

θ = 30⁰

Explanation:

We have been given two wave displacement equations,

$y_{1} =2sin\theta +1$ ........(1)

$y_{2}=3sin\theta +0.5$ ........(2)

The waves will have same displacements when $y_{1}=y_{2}=y$ (say)

Therefore, operating (2) - (1), we get,

$sin\theta - 0.5=0$

or, $\theta = sin^{-1}(0.5)=30^{o}$ (since, sin 30⁰ = 0.5)

We can check the answer by putting $\theta=30^{o}$ in equations (1) and (2),

$y_{1}=2sin30^{o}+1=2\times0.5 + 1= 2$

$y_{2}=3sin30^{o}+0.5=3\times0.5+0.5=1.5+0.5=2$

A sled with a mass of 25.0 kg rests on a horizontal sheet of essentially frictionless ice. It is attached by a 5.00-m rope to a

Tpy6a [65]

Answer:

The value is $F = 34.3 \ N$

Explanation:

From the question we are told that

The mass of the shed is $m = 25 \ kg$

The length of the rope is $l = 5.0 \ m$

The angular speed of the shed is $w = 5 rev/minute = \frac{2* \pi * 5}{60 }= 0.524 \ rad/sec$

Generally the force exerted on the shed is mathematically represented as

$F = m * w^2 * l$

=> $F = 25 * 0.524^2 * 5$

=> $F = 34.3 \ N$
