Imagine you are in an open field where two loudspeakers are set up and connected to the same amplifier so that they emit sound waves in phase at 688 Hz. Take the speed of sound in air to be 344 m/s. Part A. If you are 3.00 m from speaker A directly to your right and 3.50 m from speaker B directly to your left, will the sound that you hear be louder than the sound you would hear if only one speaker were in use? a. yes b. no Because the path difference is equal to the wavelength of the sound, the sound originating at the two speakers will interfere constructively at your location and you will perceive a louder sound. Part B. What is the shortest distance d you need to walk forward to be at a point where you cannot hear the speakers? The forward direction is defined as being perpendicular to a line joining the two speakers and you start walking from the line that joins the two speakers.

Answer:
684J
Explanation:
So basically the formula for gravitational potential energy is Mass X Gravity X height. That is G.p.e = mgh
We don't have the mass but since we have the height, we multiply directly with the height since the quantity of weight is already given.
so G.p.e = 360 X 1.9 = 684J
Note that; The answer is in joules because g.p.e is work done.
Hope that was helpful!!

Work is the product of force multiplied by the distance moved, but since the distance moved in the vertical direction is zero
Work Done = 0 joules
Given data
Force = 125N
Horizontal Distance = 2 m
Vertical distance = 0 m
Formula for work
Work = Force * Distance
Solution
substitute the given information
Work Done in the horizontal direction= 125*2
Work Done = 250 Joules

Answer:
Explanation:
1) First of all, we need to calculate the heat needed to raise the temperature of the block of lead from the initial temperature (25.0 C) to the melting temperature (327.5 C). This heat is given by the equation
where
m = 2.00 kg is the mass of the block
Cpb = 130.0 J/kg*C is the specific heat capacity of lead
is the temperature difference
Substituting,
2) Now we have to calculate the amount of heat needed to completely melt the lead, which is given by:
where
Hj = 2.04x10^4 J/kg is the latent heat of fusion of lead
Substituting,
3) Therefore, the total heat needed is
Answer:
Q = 2.00kg x 130 J/kgC x 302.5C
Q = 7.87 x 10^4j
Q = 2.00kg x 2.04 x 20^4
Q= 4.08 x 10^4
Q = 7.87 x 10^4j + 4.08 x 10^4 = 1.2 x 10^5j

Lipoproteins are essentially a hub full of fat and cholesterol, along with a lipid layer that includes proteins named apolipoproteins. There are many kinds of lipoproteins, but the two most prominent ones are called Low-Density Lipoprotein and HDL.LDL particles are seldom related to as bad lipoprotein because of concentrations, dose-related, associated with atherosclerosis change. High-density lipoproteins (HDL) get fat molecules from the body's cells and take it back to the liver.
