There are two forces acting on a rocket at the moment of lift off: Thrust pushes the rocket upwards by pushing gases downwards in the opposite direction.Weight is the force due to gravity pulling the rocket downwards towards the centre of the earth.So I'm thinking the answer is THRUST.
The energy of a photon is given by
where
is the Planck constant
f is the frequency of the photon
In our problem, the frequency of the light is
therefore we can use the previous equation to calculate the energy of each photon of the green light emitted by the lamp:
➡ 150hrs.
➡ Time = distance × speed
➡ Time = 15*10
➡ Time = 150hrs ans.
c-undergoes the most change
Explanation:
Horizon B is the layer in a soil profile that has undergone the most change.
A section through a typical soil reveals many of the different layers.
The rock layers are divided into sections which are called horizons.
Horizon O is the organic matter
Horizon A is the top soil
Horizon B is the subsoil.
The subsoil of horizon B is the layer that undergoes the most change. It materials are constantly being leached away from this layer by chemical weathering. Some of the processes here accounts for it typical reddish brown color.
The rock layer here is rich in iron oxide and washed down minerals. It lacks significant amount of humus.

The mass of the water in the system is one parameter that can be taken into consideration that is kept constant.
Describe a constant.
A constant in science is a kind of unaltered variable that stays constant together with the experimental process.
It is important to take into account a system's constants, which cannot be altered by experiments or observations.
In conclusion, the mass of the water can be taken into consideration as a continuous system parameter.
