A 0.900 kg ornament is hanging by a 1.50 m wire when the ornament is suddenly hit by a 0.400 kg missile traveling horizontally a

just olya [345]

Explanation:

The given data is as follows.

Mass of the ornament ( $m_{1}$ ) = 0.9 kg

Length of the wire (l) = 1.5 m

Mass of missile ( $m_{2}$ ) = 0.4 kg

Initial speed of missile ( $u_{2}$ ) = 12 m/s

r = 1.5 m

According to the law of conservation of momentum,

$p_{i} = p_{f}$

$m_{1}u_{1} + m_{2}u_{2} = (m_{1} + m_{2})v$

Putting the given values into the above formula as follows.

$m_{1}u_{1} + m_{2}u_{2} = (m_{1} + m_{2})v$

$0.9 \times 0 + 0.4 \times 12 = (0.9 + 0.4)v$

0 + 4.8 = 1.3v

v = 3.69 m/s

Now, the centrifugal force produced is calculated as follows.

$F_{c} = (m_{1} + m_{2}) \times \frac{v^{2}}{r}$

= $(0.9 + 0.4) \times \frac{(3.69)^{2}}{1.5}$

= 11.80 N

Hence, tension in the wire is calculated as follows.

T = $F_{c} + (m_{1} + m_{2})g$

= $11.80 N + (0.9 + 0.4) \times 9.8$

= 24.54 N

Thus, we can conclude that tension in the wire immediately after the collision is 24.54 N.

Does the surrounding air become warm or cool when vapour phase of H2O condenses? Explain

mel-nik [20]

The surrounding air will become warm when water vapor condenses. The vapors when become water will give away latent heat they have, we know that latent heat is required for the object to change states, so, the latent heat the water vapor had when it became water vapor from water will be given out when it again becomes water.
