Your answer would be oxygen because when doing moderate to vigorous workouts, your body needs more oxygen to be supplied to your muscles.
Answer:
True.
This is because, from the information provided so far, it could be concluded that, the policy makers don't have any single idea of what they are doing regarding to the economy.
This could be seen in the series of poor performance of the economic indicators as shown which has lead to poor economic growth in our country.
Explanation:
positions.
B. Compressions and rarefactions occur throughout a transverse wave.
C. The wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
D. Amplitude of longitudinal waves is measured at right angles to the direction of the travel of the wave and represents the
maximum distance the molecule has moved from its normal position.
Before coming into conclusion first we have to understand the nature of longitudinal wave and transverse wave.
The longitudinal wave is a type of mechanical wave in which the direction of wave propagation is parallel to the particle vibration.In such type of wave one will notice compressions and rarefactions.
Compressions are the high pressure zones where the particles are very close to each other and rarefactions are the low pressure regions where there is large separation between particles. Hence a longitudinal wave is a series of compresions and rarefactions.
The wavelength of a longitudinal wave is the distance between two successive compressions or rarefactions. Hence the wavelength is measured parallel to the direction of wave. As the particle vibration is parallel to wave propagation ,so the amplitude of the wave is measured parallel to wave direction.
Transverse wave is such type of mechanical wave in which the particle vibration is perpendicular to wave propagation.Here crests and troughs are formed.
The distance between two successive crests or troughs are called wavelength which is measured parallel to the wave propagation. As the particle vibration is perpendicular to wave propagation,so the amplitude of the wave is measured perpendicular to the wave propagation.It is so because amplitude of the wave is the maximum distance travelled by the particle from equilibrium position.
Out of the four options given in the question only the option 3 is correct .Other options are wrong as violate the nature of longitudinal and transverse waves.
Answer:
C. The wavelength of both traverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
Explanation:
Answer:
The period of this wave es 10 seconds.
Explanation:
The wavelength is the minimum distance between two points of the wave that is in the same state of vibration.
Frequency is the number of vibrations that occur in a unit of time.
The speed of propagation is the speed with which the wave propagates in the middle. Relate wavelength (λ) and frequency (f) inversely proportionally using the following equation: v = f * λ.
The period is the time that elapses between the emission of two consecutive waves. In other words, it is the time it takes for a complete wave to pass through a reference point. The period (T) is simply the inverse of the frequency (f):
The units of the period are the seconds (s)
Then the propagation speed will be v = λ / T (Speed = wavelength/period)
Then T= λ / v
Period (T)= 10 s
The period of this wave es 10 seconds.
Answer:
.10 sec
Explanation:
b. increase the area over which the person’s weight is distributed.
c. increase the pressure on the snow.
d. increase the buoyancy of the person.
Answer:
Option B is correct.
Explanation:
Snowshoes has large area of crossection.
As a person wears the snowshoes, the weight of the person distributed over a large area and thus the pressure exerted by the surface due to the weight of the person is less.
The relation among pressure, force and area of crossection is given below.
As area of crossection is large, pressure is small and thus the person walk on deep snow.
Answer:
Recoil speed = -100,000 m/s
Explanation:
First, this is an exercise that has relation with angular momentum.
So, you need to use the expressions for momentum.
Now, we can assume that Superman and the asteroid are initially at rest, so both moments are 0.
If superman hurls the asteroid, this means that he should have an equal moment but in the opposite direction of the asteroid, therefore, he also have an opposite recoil moment.
The expression to use is the following:
innitial momentum = final momentum
The final momentum, is the combination of superman recoil moment, and the asteroid so:
0 = Mass * Velocity
Let M1 and V1 be the mass and velocity of superman, while M2 and V2 would be the asteroid, thus we have:
0 = M1 * V1 + M2 * V2
As the problem states, the asteroid is 1000 times more massive than superman, so we can say that M2 = 1000M1. Replacing in the above expression we finally have:
0 = M1 * V1 + 1000M1 * V2
M1 * V1 = -1000M1V2 -----> Simplify M1
V1 = -1000V2
V1 = -1000 * 100
V1 = -100,000 m/s
This would be the recoil speed of Superman.
Answer:
-100,000m/s
