Answer:
The molecules in a solid are all packed together and vibrating.
The molecules in a liquid are able to fit into a space, because they aren't packed together, they are more apart from each other.
The molecules in a gas are even further apart from each other, and able to move way more freely.
Explanation:
Solid things are solid because of the molecules being so packed together.
Liquid things are liquid because of there being not as many in one space, it's more spread out.
Gas things are gas because of the molecules moving fast and there aren't as many so it's more spread out than other things.
I hope this helped!
The second one because the zeroes in the middle count. 2.0002
Answer:
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
Explanation:
The orbital velocity of the Earth about the sun is 30 km/s. If we shoot a rocket with 30 km/s with respect to Earth in the opposite direction. Then the two velocity vectors cancel. The resultant velocity would be zero with respect to the Sun. resulting velocity is called as tangential velocity.
Planet will crash on to the Sun if the tangential velocity becomes zero and Rocket should be fired from Earth's orbit is at 30 m/s and in opposite direction to the Earth orbits the Sun
First calculate the time it would take for the crate to
fall using the formula:
h = v0 t + 0.5 g t^2
110 m = 0 + 0.5 (9.8 m/s^2) t^2
t = 4.74 s
The crate is also moving at 46 m/s on with respect to the
horizontal surface, therefore distance covered is:
d = (46 m/s) * 4.74 s
d = 217.95 m
The crate would fall 217.95 m from the tail of the car.
