Answers

Answer 1

Answer:

The part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life.

Explanation:

It’s in the definition of biosphere. “Bio” means “life,” so “biosphere” is that portion of the Earth capable of supporting life.

When energy is added to a wave, how can the wave change?.

Answers

Answer:

When waves overlap in-phase (crest meets crest or trough meets trough) the waves energy is additive and the amplitude increases.

Explanation:

When waves overlap out-of-phase (crest meets trough) the waves cancel and the amplitude (energy) decreases. When two interfering waves cancel each other out.

(a) before the submarines pass each other, sub b quickly turns around and speeds up to 12. 4 m/s. What is the change in frequency noticed by observers on sub b? (enter you answer to one decimal place. )

Answers

The change in frequency noticed by observers on sub b is : 2.66 Hz before the submarines pass each other.

Given data:

New speed of Sub b ( Vb ) = 12.4 m/s

F₁ = 1416.44 Hz

Frequency of sonar wave ( Fₐ ) = 1400 Hz

Speed of sound in water ( V ) = 1533 m/s

Speed of submarine A ( Va ) = 8.4 m/s

Determine the change in frequency observed on sub B

The change in frequency can be calculated using the formula below

F₁' = Fₐ ( V + Vb / V - Vₐ )

    = 1400 ( 1533 + 12.4 / 1533 - 8.4 )

    = 1400 ( 1545.4 / 1524.6 )

    = 1419.1 Hz

Final step : determine the change in frequency

ΔF = F₁' - F₁

    = 1419.1 - 1416.44

    = 2.66 Hz.

Hence we can conclude that The change in frequency noticed by observers on sub b is : 2.66 Hz.

The frequency is the number of waves that travel through a particular place in one unit of time. The change in frequency noticed by observers on sub b is 2.66 Hz.

What is the frequency?

The frequency is the number of waves that travel through a particular place in one unit of time. It may also be described as the number of cycles or vibrations experienced by a body in periodic motion in one unit of time.

Given that the new speed of the sub B is 12.4 m//sec, while the frequency of the submarine is 1416.44 Hz. The frequency of the sonar wave of submarine A is 1400 Hz. Also, the speed of sound in water, V is 1533 m/sec, and the speed of submarine A is 8.4 m/s.

Now, the frequency of the sub B after the speed is increased will be equal to,

[tex]F_1' = F_a \times \dfrac{(V+V_b)}{(V-V_a)}[/tex]

      [tex]\rm = 1400 \times \dfrac{(1533+12.4)}{(1533-8.4)}\\\\=1400 \times \dfrac{1545.4}{1524.6}\\\\=1419.1\ Hz[/tex]

Further, the change in frequency noticed by observers on sub b,

[tex]\rm \triangle F = F_1'-F_1 = 1419.1-1416.44 = 2.66\ Hz[/tex]

Hence, the change in frequency noticed by observers on sub b is 2.66 Hz.

If there were no external forces acting on the two pucks, their complex motion could be described as the combination of the uniform linear motion of the center of mass and a uniform circular motion of the pucks about the center of mass. Describe how well your results agree with this expectation, and explain any deviations that you observe from the predicted behavior

Answers

The absence of external forces will make the pucks move in the form of a uniform circular motion.

What is a circular motion?

It should be noted that a circular motion simply means the movement of an object along the circumference of the circle.

In this case, the absence of external forces will make the pucks move in the form of a uniform circular motion.

If the friction is absent, the pucks will continue to move on the same path due to the first law of Newton and the law of conversation of energy. In this case,the results will match the predictions until there's loss in energy.

A piece of cheese is placed on a vertical spring of negligible mass and a force constant k = 2300 N/m that is compressed by a distance of 18.0 cm. How much elastic potential energy is stored in this system? (Answer in J)

Answers

Answer:

E = 1/2 K x^2        (1/2 *F * x * x)

E = 2300 / 2 N/m * (.18 m)^2 = 37.3 Joules

The quantity of elastic potential energy that is currently stored in the system is equal to 37.26 Joules (J).

We may use the formula for elastic potential energy to compute the amount of elastic potential energy that is stored in the system, which is as follows:

PE, or Elastic Potential Energy, is 0.5 times k times x squared.

where k represents the constant force that the spring exerts and x represents the amount of compression that the spring experiences.

Given:

The spring has a force constant of 2300 Newton-meters (k).

The spring was compressed (x) by 18.0 centimetres, which is equivalent to 0.18 metres when measured in metres.

To finish, enter the values into the formula as follows:

PE = 0.5 × 2300 N/m × (0.18 m)² PE = 0.5 × 2300 N/m × 0.0324 m² PE = 37.26 J

37.26 Joules (J) is the amount of elastic potential energy that is stored in the system.
