Answer:
The Young's modulus for this alloy of aluminum is
Explanation:
Given that,
Diameter = 0.12 cm
Length = 2.4 m
Mass = 37 kg
Stretch length = 1.24 cm
Density = 2.7 g/cm³
We need to calculate the area
Using formula of area
Put the value into the formula
We need to calculate the Young's modulus
Using formula of Young's modulus
Put the value into the formula
Hence, The Young's modulus for this alloy of aluminum is
In a parallel circuit the voltage is the same across all branches.
Answer: Pressure fluctuations travel along the direction of propagation of the sound wave.
Explanation:
Sound wave is a type of longitudinal wave. It is defined as a wave which consist of vibrations of particles traveling through a medium( such as air, or water).
Sound wave is propagated by the alternating adiabatic compression and expansion of the medium. The COMPRESSIONS are regions of high air pressure while the RAREFACTIONS are regions of low air pressure. Therefore, Since a sound wave consists of a repeating pattern of high-pressure and low-pressure regions moving through a medium, it is sometimes referred to as a PRESSURE WAVE.
The direction of the vibrating particles is parallel to the direction of propagation and that's why it's a type of LONGITUDINAL WAVE. Therefore, the correct option that
concludes about the direction in which such pressure fluctuations travel is
(Pressure fluctuations travel along the direction of propagation of the sound wave.)
Answer:
Observation 1 represents a solar wind because solar winds are a continuous stream of particles given off by the sun.
Explanation:
Answer:
Explanation:
If Ig be moment of inertia about an axis through centre of mass and I be moment of inertia through any other axis parallel to earlier axis , then according to theory of parallel axis ,
I = Ig + Md²
where M is mass of the body and d is distance between two parallel axis.
So I is greater than Ig.
