A clown hangs two balloons from either end of a hanger. The air from on balloon is released, and the hanger tilts. Which principle is illustrated? a. gas is matter, and therefore has mass b. gas has volume that is not measurable c. released gas has a higher temperature than inert gas d. matter may never be destroyed

Answers

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.

Air flowing from the equator to the poles rises and falls in looping patterns. What are these patterns called?A. The Coriolis Effect
B. Convection Cells
C. Emanation Cells
D. Radiation

Answers

These patterns are called

B. Convection Cells

What are 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).

The correct answer for the given question above would be option B. Air flowing from the equator to the poles rises and falls in looping patterns and these patterns are called convection cells. Convection cells is an important process in the formation of landforms and the movement of winds. Hope this answers your question.

The acceleration of gravity is a constant equal to _______ meters per second squared.A. 9.8
B. 8.4
C. 10.2
D. 7.6

Answers

The acceleration due to gravityis the acceleration on an object caused by force of gravitation. It means thatthe earth has a gravitational field that projects all bodies on earth towards itscenter. The gravity of an object or body of an object is high on earth than atthe atmosphere. It has an average of gravitational constant equal to 9.8066 or9.8 meters per second. In truth, the acceleration of the object depend upon itslocation, the latitude and altitude, on earth.

Answer:

A. 9.8

Explanation:

The tendency for an object in motion to remain in motion is called ____________________.

Answers

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.

A stone thrown from a height of 5.72 meters hits the ground at 13.3, Calculate the initial speed. Neglect air resistance

Answers

Answer:

12.31618 m/s

Explanation:

s = Displacement

t = Time taken

g = Acceleration due to gravity = 9.81 m/s² = a

$s=ut+(1)/(2)at^2\n\Rightarrow 5.72=0t+(1)/(2)* 9.81* t^2\n\Rightarrow t=\sqrt{(5.72* 2)/(9.81)}\n\Rightarrow t=1.07988\ s$

Velocity is given by

$v=(s)/(t)\n\Rightarrow v=(13.3)/(1.07988)\n\Rightarrow v=12.31618\ m/s$

The initial velocity is 12.31618 m/s

Imagine that a tank is filled with water. The height of liquid column is 7 meters and the area is 1.5 square meters (m2). What's the force of gravity acting on the column of water?

Answers

-- The volume of water is (1.5 m² x 7 m) = 10.5 m³

   10.5 m³ = 10,500 liters

   Water mass = (10,500 liters) x (1 kg/liter) = 10,500 kg.

-- "Force of gravity on the water"

= Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons

-- Pressure on the bottom of the tank =

   (102,900 newtons) / (1.5 m²)

   = 68,600 nt/m² = 68,600 pascal .

your answer is 102,900 N
