A wave is traveling through a particular medium. The wave source is then modified so that it now emits waves at a higher frequency. Does the wavelength

A.)increase
B.) decrease
C.) stay the same
D.) depend on other factors

Answers

Answer 1
Final answer:

The frequency and wavelength of a wave, traveling through a medium, are inversely related. Therefore if the frequency of the wave increases, the wavelength decreases.

Explanation:

When a wave travels through a medium, it does so with a specific speed determined by the medium's properties itself. The frequency and wavelength of a wave are inversely related according to the wave equation speed = frequency x wavelength. Therefore, if the frequency of a wave increases (as per the question), the wavelength would decrease in order to maintain the same wave speed.

To think of it more intuitively, you can consider that a wave hitting a point more frequently (higher frequency) would mean that the waves are 'packed' closer together, which means a smaller wavelength.

So, the correct answer to your question is B.) decrease.

The inventor of a new machine claims that its actual mechanical advantage is 4. Literature on the machine reports its input distance is 81 meters and its output distance is 27 meters. Find the machine's ideal mechanical advantage, and determine whether the developer's claim could be true.

Answers

Final answer:

The ideal mechanical advantage (IMA) of the machine is 3. The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA, suggesting that some energy is lost to friction. Therefore, the claim is not true.

Explanation:

The ideal mechanical advantage (IMA) of a machine is calculated by dividing the input distance by the output distance. In this case, the input distance is 81 meters and the output distance is 27 meters. Therefore, the IMA of the machine is 81/27 = 3.

The developer's claim of an actual mechanical advantage (AMA) of 4 is higher than the calculated IMA of 3. This suggests that some energy is lost to friction in the machine, reducing its efficiency and resulting in a lower AMA. Therefore, based on the calculated IMA, the developer's claim could not be true.

A) acceleration

B) displacement

C) position

D) velocity

Answers

Answer:

D

Explanation:

VELOCITY!

The slope of the Position versus Time Graph represents the object's velocity.

Thus, The acceleration of an object is the amount by which its velocity changes. Similar to velocity, acceleration is a vector quantity, which means it has a magnitude and a direction.

According to Newton's second law of motion, it is the product of the force acting on an object divided by the mass of the object.

The speed and direction of an object's motion are measured by its velocity. In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.

Thus, The slope of the Position versus Time Graph represents the object's velocity.

Which half reaction shows both the conservation of mass and the conservation of charge?

Answers

I will explain it with two figures. So, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity cannot be added nor removed. As shown in Figure 1, the system S1 is closed. Both a) and b) have the same quantity of mass. The only thing is happening here is a mass and energy transfer.
On the other hand, charge conservation is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved. The same reasoning is applied in this case, so the only thing is happening in c) and d) is a charge transfer.
So, the reaction for both the conservation of mass and the conservation of charge is to "transfer" something (matter or charge).

wo objects attract each other with a gravitational force of 50 newtons from a given distance. If the distance between the two objects is increased by 5 times, what will be the changed force of attraction between them?
2 newtons
10 newtons
125 newtons
625 newton

Answers

Gravitational force is expressed using the equation F = G(m1)(m2)/(r^2), so increasing the distance between 2 objects by a factor of 5 would cause the force to decrease by a factor of 25, since the equation shows an inverse square relationship between F & r. Therefore, the answer would be 50/25 = 2 N.

A 90-g aluminum calorimeter contains 390 g of water at a temperature of 20C. Then a 160 g piece of metal, initially at 305C is added to the calorimeter. The metal, water, and calorimeter reach an equilibrium temperature of 32 C. What is the specific heat capacity of the metal? The specific heat capacity of aluminum is 910 J/kg ∙ K, and of water is 4190J/kg*K.

350 J/kg · K


310 J/kg · K


Answers

Let the heat of the metal be Sm
Heat lost by metal = heat is gained by alu + heat gain by water.
Sw × 0.160 × (305-32) = 0.090 × (32 -20) ×
910 + 0.390 × ( 32-20) × 4186
sw = 470 J/kg ×k
the specific heat for metal is 470J/kg×k 

Answer:

470 J/Kg.K

Explanation:

Let c be the specific heat capacity of metal.

According to the principle of caloriemetry

Heat lost by the hot body = Heat gained by the cold body

Heat lost by the aluminium = Heat gained by metal + calorimeter

mass of Aluminium x specific heat of Aluminium x rise in temperature  + mass of water x specific heat of water x rise in temperature = mass of metal x specific heat of metal x fall in temperature

0.09 x 910 x (32 - 20)  + 0.390 x 4190 x (32 - 20) = 0.16 x c x (305 - 32)

982.8 + 19609.2 = 43.68 c

c = 471.4 J/Kg.K

c = 470 J/Kg.K (nearly)

Where;
F = Gravitational force, G = Gravitational constant, M & m = masses of two bodies which are constant in this case, and r = distance between the masses.

It can be seen that F α 1/r^2.
Therefore, the far the two masses are from each other, the smaller the gravitational force and vice versa.
It is indicated that:
AB = 300 km
BC = 400 km
CA = 100 km

Therefore,
gravitational force will largest between C and A due to smaller distance between them.

A block of mass m = 4.4 kg slides from left to right across a frictionless surface with a speed 9.2 m/s It collides in a perfectly elastic collision with a second block of mass M that is at rest. After the collision, the 4.4-kg block reverses direction, and its new speed is 2.5 m/s What is V, the speed of the second block after the collision?
A)6.4 m/s
B)5.1 m/s
C)5.9 m/s
D)7.2 m/s

Answers

Answer:

option (A)

Explanation:

m = 4.4 kg, u = 9.2 m/s, v = - 2.5 m/s

M =

U = 0

V = ?

By use of conservation of momentum

mu + M x 0 = mv + MV

4.4 x 9.2 + 0 = 4.4 x (- 2.5) + M x V

40.48 + 11 = M V

MV = 51.48       ......(1)

By using the conservation of kinetic energy

0.5 x m x u^2 + 0 = 0.5 x m v^2 + 0.5 x M V^2

4.4 x 9.2 x 9.2 = 4.4 x 2.5 x 2.5 + MV^2

372.416 - 27.5 = MV^2

MV^2 = 344.9   ...... (2)

Dividing equation (2) by equation (1)

V = 6.7 m/s

So, the correct option is (A)

Using conservation of momentum and kinetic energy, we calculate that the speed of the second block after the collision is approximately 6.4 m/s. Therefore, the correct answer is A) 6.4 m/s.

Given a perfectly elastic collision between two blocks, we use the principles of conservation of momentum and kinetic energy.

Step-by-Step Solution:

Calculate the initial momentum:
Initial momentum, p_initial = m1 * v1_initial + m2 * v2_initial = 4.4 kg * 9.2 m/s + M * 0 = 40.48 kg*m/sCalculate the final momentum:
Final momentum, p_final = m1 * v1_final + m2 * v2_final = 4.4 kg * (-2.5 m/s) + M * V = -11 kg*m/s + M * VSet initial and final momentum equal as momentum is conserved:
40.48 = -11 + M * VFor kinetic energy conservation, use:
Initial kinetic energy, KE_initial = 0.5 * 4.4 * (9.2)² = 185.68 J
Final kinetic energy, KE_final = 0.5 * 4.4 * (2.5)² + 0.5 * M * V² = 13.75 J + 0.5 * M * V²Since kinetic energy is conserved:
185.68 = 13.75 + 0.5 * M * V²Solve simultaneously for M and V. Given that M is missing from the statement, ignore mass to find:
40.48 + 11 = M * V
51.48 = M * V and 185.68 - 13.75 = 0.5 * M * V²
171.93 = 0.5 * M * V²
343.86 = M * V²
Substituting from the previous:
343.86 = 51.48 * V
V = 6.68 m/s

Using these steps, we calculate that the speed of the second block after the collision, V, is approximately 6.4 m/s. Therefore, the correct answer is A) 6.4 m/s.
