For constant volume processes the heat capacity of gas A is greater than the heat capacity of gas B. We conclude that when they
dimaraw [331]

Answer:

B). the temperature of B increases more than the temperature of A

Explanation:

For constant volume process, relation between molar heat capacity and temperature is given by,

$\Delta Q = mC_v \Delta T$

where, ΔQ is the amount of heat required

              m is the mass of the gas

              $C_v$ is heat capacity at constant volume

              ΔT is the change in temperature.

For a constant energy ΔQ,

$C_v=\frac{1}{\Delta T}$

Given, $(C_v)_A>(C_v)_B$

∴     $(\Delta T)_A < (\Delta T)_B $

Thus the temperature of gas B increases more than the temperature of gas A.

A cannon is rigidly attached to a carriage, which can move along horizontal rails but is connected to a post by a large spring,
Mademuasel [1]

Answer:

Explanation:

Given

mass of cannon and cart is m_1=6475.91 kg

Spring constant k=20000 N/m

mass of Projectile m_2=234 kg

Launch Velocity of cannon v_2=170 m/s

Launch angle \theta =31.3^{\circ}

As the External Force is zero therefore we can conserve momentum

Initially both Projectile and cannon is at rest

Conserving momentum in horizontal direction

m_1u_1+m_2u_2=m_1v_1+m_2v_2\cos 31.3

0+0=6475.91\times v_1+234\times 170\cdot \cos (31.3)

v_1=-\frac{234\times 170\cdot \cos (31.3)}{6475.91}

v_1=-5.24 m/s

i.e. cannon is moving in opposite direction of Projectile

Describe how elements are formed?<br>​
kenny6666 [7]
Elements are identified by the nuclei of the atoms of which they are made. For example, an atom having six protons in its nucleus is carbon, and one having 26 protons is iron. ... Heavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. This is how they are formed
