Bird bones have air pockets in them to reduce their weight. This also gives them an average density significantly less than that of the bones of other animals. Suppose an ornithologist weighs a bird bone in air and in water and finds its mass is 47.0 g47.0 g and its apparent mass when submerged is 3.60 g3.60 g (the bone is watertight). What mass of water is displaced

Answers

Answer 1

The mass of water displaced when the mass of bird bone in water and air is given, is calculated to be 43.4 g.

Given that,

Weight of bird bone in air = True weight = 47 g

Apparent weight of the bird bone when submerged = 3.6 g

The equation for apparent weight is known to be,

Apparent weight = True weight - Buoyant force

Making Buoyant force as subject, we have,

Buoyant force = 47 g - 3.6 g = 43.4 g

F b = mw × g = (m wat - m air)× g

mw = m wat - m air = 47 g - 3.6 g = 43.4 g

Thus, the mass of the water displaced is 43.4 g.

The wheel in the simplified engine of Figure 1 has radius of 0. 250 m and rotates so that the piston oscillates at angular frequency of 12. 0 rad/s. At = 0, the piston is located at =. Calculate the piston’s position, velocity and acceleration at = 1. 15 s. ​

Answers

The piston's position, velocity, and acceleration at t = 1.15 s are :

Position: 3.45 m

Velocity: 3 m/s

Acceleration: 0 m/s^2

To calculate the piston's position, velocity, and acceleration at t = 1.15 s, we need to know the angular position, velocity, and acceleration of the wheel.

The angular position of the wheel at t = 1.15 s is given by

θ = ωt + [tex]A_{0}[/tex]

where ω is the angular frequency, t is the time, and [tex]A_{0}[/tex] is the initial angular position.

Since the angular frequency is given as 12 rad/s and the initial angular position is 0, the angular position of the wheel at t = 1.15 s is

θ = 12 x 1.15 = 13.8 radians

The piston's position is given by

r = Rθ

where R is the radius of the wheel.

Substituting the value of R and θ,

r = 0.25 x 13.8 = 3.45 m

The velocity of the piston is given by

v = r' = Rθ' = Rω

Substituting the values

v = Rω = 0.25 x 12 = 3 m/s

Acceleration of the piston is given by

a = v' = Rθ'' = Rω' = R(ω^2)θ

As the angular frequency is constant, the angular acceleration is 0 so the linear acceleration is also 0.

Note: Linear acceleration is not equal to the derivative of linear velocity, it is equal to the derivative of velocity with respect to time, which is zero in this case.

The crest of one wave of amplitude 1 meter intersects the crest of another wave of amplitude 3 meter. What is the resultant amplitude

Answers

A wave crest is the tallest point in the wave with the greatest displacement value. The junction of the 3-meter and 2-meter waves produces a 1 metre amplitude.

What exactly is amplitude ?

The amplitude of a wave is the measurement of the wave from its still position to its crest or trough. It is measured in metres.

When the wave is crossed, the elevation is 3 metres and the depression is 2 metres, resulting in an amplitude that causes destructive interference. Because 3 m is above the baseline and 2 m is below it, the resultant amplitude is 3 - 2 = 1 m.

As a consequence, the resultant amplitude is one metre.

Vibration is a periodic back-and-forth motion of the particles in an elastic body or medium.

Here,

Vibrations occurs when practically any physical system is moved out of its equilibrium condition and is left to react to forces that work to bring it back into equilibrium.

A periodic shift in time is referred to as a vibration. A wave is a regular oscillation in both space and time. The waves propagate from one point to another in a medium.

Most waves travel through different media, and this affects how fast they move.

In general, waves go through solids the quickest and gases the slowest. The reason for this is that while particles in a gas are farthest to one another, those in a solid are closer to one another.

The complex impedance of the 100 mH inductance when a voltage vL(t) = 10cos(2000πt) is applied to it is: j200Ω.

What is inductance?

Inductance is a property of an electrical component that describes the ability of the component to store energy in a magnetic field when electric current passes through it.

Inductance is measured in units of henrys (H). When current flows through a component with inductance, it creates a magnetic field around the component that resists changes to the current. This resistance to changes in current is called inductive reactance and is measured in units of ohms.

The complex impedance of an inductor is given by Z = jωL, where ω is the angular frequency and L is the inductance.
Therefore, the complex impedance of the 100 mH inductance when a voltage vL(t) = 10cos(2000πt) is applied to it is:
Z = j(2000π) (100 x 10-3) = j(2π) (100 x 10-3) = j200Ω

Answers

The magnitude of the gravitational field of the planet depends on its mass and distance from the object being affected by it.

What is Gravitational field?

Gravitational field is a region of space where a mass or object experiences a force of gravity. It is caused by the presence of a massive object, such as a planet or star, which exerts a gravitational pull on other objects within its vicinity. The strength of the gravitational field is determined by the mass of the object and its distance from other objects.

The gravitational field of the planet at Point P can be calculated by using the equation,

g = G*M/r2

where G is the gravitational constant (6.67 x 10-11 Nm2/kg2), M is the mass of the planet (4 x 1026 kg), and r is the distance from the center of the planet to Point P (53,000 km).

Plugging in the values,

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (53,000 km)2

g = (6.67 x 10-11 Nm2/kg2) x (4 x 1026 kg) / (2.8409 x 1012 m2)

g = (6.67 x 10-11 Nm2/kg2) x (14.1636 x 1015 kg)

g = 9.5 x 10-5 N/kg

Therefore, the magnitude of the gravitational field of the planet at Point P is 9.50 x 10-5 N/kg.

Answers

If three subintervals of equal length are used to do midpoint Riemann sum approximation of ∫f(x)dx from 3 to 6, then width of each subinterval is  1.

To find the midpoint Riemann sum, you first need to divide the interval of integration (from 3 to 6) into three subintervals of equal length. You can choose subintervals of equal length manually by dividing the interval of integration into smaller parts. If we let the width of each subinterval be x, then the length of the interval is 6-3 = 3 and the length of each subinterval, x is 3/3 = 1.

Then, you need to find the midpoint of each subinterval by adding the left and right endpoint of each subinterval and dividing by 2.

For example, the first subinterval is from 3 to 4, so the midpoint is (3+4)/2 = 3.5

the second subinterval is from 4 to 5, so the midpoint is (4+5)/2 = 4.5

and the third subinterval is from 5 to 6, so the midpoint is (5+6)/2 = 5.5

To approximate the area under the curve of f(x) for each subinterval, you can use the value of f(x) at the midpoint of each subinterval and multiply it by the width of the subinterval.

For what period of time does the force act on the object?

Answers

Answer:

Explanation:

Given Info:

Object of mass ⇒ 1.2 kg

Velocity of 2.0m/s when it is acted on by a force of 4.0 N

Velocity of the object Increased to 5.0 m/s

Question:

For what period of time does the force act on the object?

Solve:

We first need to know the formula:

F = ma  Or F = m(v-u)/t

F = force

m = mass of an object

a = acceleration

v = Final Velocity

u = Initial Velocity

a = Acceleration

t = Time Taken

Knowing that;

Force = 4.0 N

Mass of an object = 1.2 kg

Final velocity = 5.0m/s

Initial velocity = 2.0m/s

Time taken = [t]

Now lets plug it in the formula:

F = m(v-u)/t

4.0 = 1.2(5-2)/t

t = 0.90 seconds.

Hence, period of time at which force is acted on the object is 0.90 sec.
