Answer:
B
Explanation:
Because If the pitch of a sound increases, then we know that its frequency
has increased, and its wavelength has decreased.
Answer:
A.) gas is matter, and therefore has mass
Explanation:
The principle illustrated in this scenario is a. gas is matter, and therefore has mass.
When the air from one balloon is released, it creates a flow of gas in one direction. According to the principle of gas having mass, the released gas exerts a force on the hanger, causing it to tilt. This demonstrates that gas is matter and has mass.
It's important to note that gas does have volume, which can be measured. This is not the principle being illustrated in this scenario.
The principle of released gas having a higher temperature than inert gas is not applicable in this scenario, as no information is given about the temperatures of the gases involved.
The principle of matter may never be destroyed is a general principle in physics and does not specifically apply to this scenario.
B. Convection Cells
C. Emanation Cells
D. Radiation
These patterns are called
B. Convection Cells
The equatorial region receives the maximum amount of sunlight as the sun is directly above it. Due to this, the earth experiences a higher temperature, as a result of which the air in this region becomes warm and less dense. It then slowly rises up towards the upper atmosphere, forming a low pressure zone. This air when rises up, slowly cools, and after sometime it falls back. This continuous motion of air mass creates convection cells in the atmosphere.
Thus, the correct answer is option (B).

D. 7.6
Answer:
A. 9.8
Explanation:
Answer: The correct answer is "inertia".
Explanation:
Inertia: It is the state of the object which resists any change in it.
Newton's first law is also called "Law of inertia".
If the object is travelling at constant velocity then it will remain travel at the constant velocity or if it is at rest then it will remain in resting position provided that it is acted upon by an external force.
If the external force is applied to an object then, the state of the object can be changed. Otherwise, it will remain in its state.
Therefore, the tendency for an object i motion to remain in motion is called inertia.
Answer:
12.31618 m/s
Explanation:
s = Displacement
t = Time taken
g = Acceleration due to gravity = 9.81 m/s² = a
Velocity is given by
The initial velocity is 12.31618 m/s
your answer is 102,900 N
