How would the elastic potential energy change if the displacement is multiplied by five?

1 answer:

3 0

Answer: Work is done when a spring is extended or compressed . Elastic potential energy is stored in the spring. The elastic potential energy stored can be calculated using the equation: elastic potential energy = 0.5 × spring constant × (extension) 2.

The speed of a sound wave traveling through air is 400 meters per second. The wavelength of the wave is 25 meters What is the

sweet [91]

Answer:

16Hz

Explanation:

Given parameters:

Speed of sound = 400m/s

Wavelength = 25m

Unknown:

Frequency of the wave = ?

Solution:

To solve this problem;

V = F ∧

V is the velocity

F is the frequency

∧ is the wavelength

400 = F x 25

F = 16Hz

You have an incident ray from a medium with a n1=1, through a medium with a n2 =3.325. If the incident angle is equal to 0.478 r

sesenic [268]

Answer:

0.139 rad

Explanation:

We use Snell's law $n_1sin\theta_1=n_2sin\theta_2$ , where if $n_1$ is the refractive index of the medium containing the incident ray, $\theta_1$ would be the incident angle, and if $n_2$ is the refractive index of the medium containing the refracted ray, $\theta_2$ would be the refraction angle, which we want, so we do:

$sin\theta_2=\frac{n_1}{n_2}sin\theta_1$

And finally:

$\theta_2=arcsin(\frac{n_1}{n_2}sin\theta_1)$

We then insert our values:

$\theta_2=arcsin(\frac{n_1}{n_2}sin\theta_1)=Arcsin(\frac{1}{3.325}sin(0.478rad))=arcsin(0.13834714686
)=0.139 rad$

Two identical objects, A and B, are sitting on a table. If the net force on object A is 5 N and the net force on object B is 10

sveta [45]

If the net force on object A is 5 N and the net force on object B is 10 N, then object B will accelerate more quickly than object A provided the mass of both objects are same.

Answer: Option C

Explanation:

According to Newton’s second law of motion, any external force applied on an object is directly proportional to the mass and acceleration of the object. In order to state this law in terms of acceleration, it is stated that acceleration exhibited by any object is directly proportional to the net force applied on the object and inversely proportional to the mass of the object as shown below:

$\text {Acceleration of the object } \propto \frac{\text {Net force on the object}}{\text {Mass of the object}}$

So if two objects A and B are identical which means they have same mass, then the acceleration attained by the object will be directly proportionate to the net forces exerted on the objects only.

Thus if the force applied is more for one object, then the object will be exhibiting more acceleration compared to the other one. So as object B is experiencing a net force of 10 N which is greater than the net force experiences by object A, then the object B will be accelerating more quickly compared to the object A's acceleration.
