The average kinetic energy of water molecules is greatest in

Physics

<h2>Answer: in a gaseous state </h2>

The average kinetic energy of the water molecules is greater in its gaseous state (in the form of water steam).

This is because in the gaseous state the water molecules are well separated from each other and can move freely in all the available space they have; because there are no cohesion forces that bond them.

In contrast to the liquid and solid state, in which the molecules have less movement.

An airplane with an airspeed of 120 km/h has a heading of 30 degree east of North in a wind that is blowing toward the east at 6
lesya692 [45]

Answer:

Explanation:

Velocity of plane relative to ground V_pg = ?

Given the velocity in vector form ,

velocity of plane relative to air V_pw = 120 cos30 i + 120sin30j

V_wg = 60 i

V_pg = V_pw +V_wg

= 120 cos30 i + 120sin30j + 60i

= 164 i + 60 j

magnitude

=251 km / h

A drone flies 8 m/s due East with respects to the wind. The wind is blowing 6 m/s due North with respects to the ground. What is
vekshin1

Answer:

B. 10m/s

Explanation:

If a drone flies 8 m/s due East with respects to the wind and the wind is blowing 6 m/s due North, the speed of the drone with respect to the ground is its displacement.

Displacement is calculated using Pythagoras theorem.

d² = 8²+6²

d² = 64+36

d² = 100

Square root both sides

√d² = √100

d = 10m/s

Hence the distance of the drone with respect to the ground is 10m/s

Option B is correct

If the total momentum for a system is the same before and after the collision, we say that momentum is conserved. If momentum we
andrew-mc [135]

Answer:

Ratio = 1:1

Explanation:

P_{i} = initial momentum of the system

P_{f} = final momentum of the system

For the momentum to be conserved , final total momentum must be equal to initial total momentum, so we have

P_{f} = P_{i}

Dividing both side by P_{i} , we get

\frac{P_{f}}{P_{i}} = \frac{P_{i}}{P_{i}} \\\frac{P_{f}}{P_{i}} = 1\\

hence

Ratio = 1
