The speed of a wave is determined by multiplying the wavelength by the frequency

Answers

Answer 1

Answer:
Wellll . . . that's not a very easy way to do it. You'd still need
to figure out a way to measure the wavelength AND a way to
measure the frequency, so you won't find many engineers
actually trying to determine the wave speed by doing all of that.

But your statement is correct. The product of

(wavelength) times (frequency)

IS the speed of the wave.

Which lists the springs based on the amount of elastic potential energy from greatest to least

Answers

The elastic potential energy stored in the spring is

= (1/2) x (spring constant) x (distance stretched or compressed)²

If all four springs are stretched or compressed the SAME distance
from their equilibria, then the potential energy is just proportional
to the spring constant.

From greatest to least stored energy is exactly the same list as
from greatest to least spring constant:

X . . . . . 35
W . . . . . 24
Y . . . . . 22
Z . . . . . 15

The following list, which ranks stored energy from highest to lowest, also ranks spring constant from highest to lowest: X, W, Y, Z. Hence, option B is correct.

What is potential energy?

Potential energy is a form of stored energy that is dependent on the relationship among different components. When a spring is compressed or stretched, its potential energy increases. If a steel ball is raised above the floor as opposed to falling to the ground, it has more potential energy. It is capable of carrying out additional work when raised.

Potential energy is a feature of systems rather than of particular bodies or particles; for instance, the system created up of Earth and the elevated ball has more energy stored as they become further apart.

Potential energy develops in systems components whose configurations, or spatial arrangement, determine the amount of the forces they apply to one another.

The spring's potential elastic energy is stored as:

= (1/2) x (spring constant) x (distance compressed or stretched)²

So, the order from greatest to least will be:

X = 35

W = 24

Y = 22

Z = 15

Peregrine falcons frequently grab prey birds from the air, as BI0 in Example 9.10. Sometimes they strike at high enough speeds that the force of the impact disables prey birds. A 480 g per- egrine falcon high in the sky spies a 240 g pigeon some dis- tance below. The falcon slows to a near stop, then goes into ve-called a stoop-and picks up speed as she falls. The n reaches a vertical speed of 45 m/s before striking the pigeon, which we can assume is stationary. The falcon strikes the pigeon and grabs it in her talons. The collision between the falco birds lasts 0.015 s. a. What is the final speed of the falcon and pigeon? b. What is the average force on the pigeon during the impact?

Answers

A) 30 m/s

The problem can be solved by using the law of conservation of momentum. In fact, the total momentum falcon+pigeon before the collision must be equal to the total momentum falcon+pigeon after the collision:

$p_i = p_f$

$m_f u_f + m_p u_p = (m_f + m_p) v$

where

mf = 0.480 g is the mass of the falcon

uf = 45 m/s is the initial velocity of the falcon

mp = 0.240 g is the mass of the pigeon

up = 0 is the initial velocity of the pigeon

v is the final combined velocity of pigeon+falcon

Solving the equation for v, we find

$p=(m_f u_f)/(m_f +m_p)=((0.480 kg)(45 m/s))/(0.480 kg+0.240 kg)=30 m/s$

B) 480 N

The average force on the pigeon during the impact is given by

$F=(\Delta p)/(\Delta t)$

where

$\Delta p$ is the change in momentum of the pigeon

$\Delta t$ is the duration of the collision

here we have:

- Change in momentum of the pigeon:

$\Delta p = m (v-u)=(0.240 kg)(30 m/s-0)=7.2 kg m/s$

- Duration of the collision:

$\Delta t=0.015 s$

So the average force is

$F=(7.2 kg m/s)/(0.015 s)=480 N$

Final answer:

To determine the final speed of the falcon and pigeon, we need to use the principles of conservation of momentum. To calculate the average force on the pigeon during the impact, we can use the equation for impulse. The primary topic of this question is conservation of momentum and impulse.

Explanation:

To determine the final speed of the falcon and pigeon, we need to use the principles of conservation of momentum. Since the pigeon is assumed to be stationary, its initial momentum is zero. The final momentum of the falcon and pigeon combined must also be zero, according to the law of conservation of momentum. Using the equations for momentum and rearranging, we can solve for the final speed of both the falcon and pigeon.

To calculate the average force on the pigeon during the impact, we can use the equation for impulse, which is the change in momentum. Impulse is equal to force multiplied by the time of impact. Rearranging the equation, we can solve for force.

The greater the concentration of sulfur and nitrogen oxides, the higher the pH of precipitation.True
False

Answers

Answer: False

Nitrogen and sulfur dioxide are acidic oxides in nature. The burning of fossil fuels and other sources are responsible for addition of these oxides in the atmosphere of earth. These oxides mixed with water vapor causes acid rain. Being acidic in nature they will have low pH value. Therefore, greater the concentration of sulfur and nitrogen oxides, will lower the pH value of precipitation.

In deeper ocean water, temperature decreases and pressure increases. t/f

Answers

Answer:

It is false.

Explanation:

As the depth of water increases, the pressure also increases.

According to the formula

$P = h * d * g$

Where, h is the depth of water, d is the density of water and g be the acceleration due to gravity

As h increases, pressure also increases.

As depth increases, the temperature of the water also increases, because of geothermic energy of earth.

So, as depth increases, pressure and temperature both increases.

When the temperature of water increases from room temperature to 90ºC the process of heating the water is... Question 9 options: A. adiabatic
B. exothermic
C. isothermic
D. endothermic
E. all of the above

Answers

Answer : The correct option is, (D) Endothermic

Explanation :

Adiabatic : It is a process in which a heat is constant. That means no heat is lost or gained by the system.

Isothermic : It is a process in which a temperature is constant.

Exothermic : It is a process in which heat released from system to surrounding. In this process, surrounding temperature increases and system temperature decreases.

Endothermic : It is a process in which heat required from the surrounding. In this process, surrounding temperature decreases and system temperature increases.

When the temperature of water increases from room temperature to 90ºC the process of heating the water is endothermic.

Hence, the correct option is, (D) Endothermic
