A helium balloon is filled to a volume of 2.88 x 103 L at 722 mm Hg and 19Â°C. When the balloon is released, it rises to an alti

inn [45]

Answer:

V₂=4.57 x 10³ L

Explanation:

Given that

V₁= 2.88 x 10³ L

P₁=722 mm Hg

T₁ = 19°C

T₁ =292 K

P₂=339 mm Hg

T₂= - 55°C

T₂=218 K

Lets take final volume = V₂

We know that ideal gas equation

PV = m R T

By applying mass conservation

$\dfrac{P_1V_1}{RT_1}=\dfrac{P_2V_2}{RT_2}$

$\dfrac{722\times 2.88\times 10^3}{292}=\dfrac{339\times V_2}{218}$

V₂=4.57 x 10³ L

Therefore volume will be 4.57 x 10³ L

an NHL hockey player (m=90 kg) stands motionless on the ice . the 10 kg stanley cup is thrown to the player at 4m/s. after he ca

spayn [35]

Answer:v=0.4 m/s

Explanation:

Mass hockey player $m_1=90 kg$

mass of cup $m_2=10 kg$

Velocity of cup $u=4 m/s$

let v be the velocity of the combined system

Conserving momentum

$m_1\cdot 0+m_2u=(m_1+m_2)v$

$v=\frac{10\times 4}{100}$

$v=\frac{40}{100}$

$v=0.4 m/s$

What happens as a result of the pulses passing by each other?

nadezda [96]

Answer:

After pulses pass through each other, each pulse continues along its original direction of travel, and their original amplitudes remain unchanged.

Explanation:

Constructive interference takes place when two pulses meet each other to create a larger pulse.
