Matter is __________. A. the amount of energy contained within an object B. a measure of the force gravity exerts on objects C. something that has mass and occupies space D. a measure of an object's inertial force Please

Th correct answer to this question would be, Insulator. Notice in the question it says "Material". The question is basically asking, What item resists the flow of and electric current. A resistor is a device that suppose to strain the electric  current. And resistance is the measure of how well the material can conduct an electric charge. With all of that being stated, Insulator materials include paper, dry wood, rubber, glass, ect. Insulator products provides resistance.

Make sure you read the questions very carefully.

Answer: Insulator

Explanation: Insulators stop electric currents from going through

Explanation:

The right-hand rule, also known as the Buys-Ballot's law, helps explain the rotation of winds around high and low pressure centers in the Northern Hemisphere. According to this rule:

1. In a low pressure center (cyclone) in the Northern Hemisphere, the wind rotates counterclockwise around the low-pressure center. If you extend your right hand with your thumb pointing upwards, your fingers will curl in the counterclockwise direction, representing the direction of the winds.

2. In a high pressure center (anticyclone) in the Northern Hemisphere, the wind rotates clockwise around the high-pressure center. If you extend your right hand with your thumb pointing upwards, your fingers will curl in the clockwise direction, representing the direction of the winds.

This rule is based on the Coriolis effect, which is caused by the Earth's rotation. As air flows from areas of higher pressure to lower pressure, it is deflected by the Coriolis force due to the Earth's rotation. In the Northern Hemisphere, the Coriolis force deflects moving air to the right. This deflection, combined with the pressure gradient force, results in the counterclockwise rotation around low-pressure centers and clockwise rotation around high-pressure centers.

It is important to note that the right-hand rule is specific to the Northern Hemisphere. In the Southern Hemisphere, the opposite is true. The wind rotates counterclockwise around low-pressure centers and clockwise around high-pressure centers.

Understanding the rotation of winds around pressure centers is essential in meteorology for predicting weather patterns and systems. By studying these rotations, meteorologists can make informed forecasts and predictions about the movements and impacts of weather systems.

Answer:

the center of gravity moves by 1.9 m towards the origin

Explanation:

from the question we are given the following

John's mass (Mj) = 91.2 kg

Barbara's mass (Mb) = 51.9 kg

John's location (Xj) = + 9.99 m

Barbara's location (Xb) = +3.27 m

center of mass (X) = ?

the center of mass is where the masses of John and Barbara is concentrated, and it is given by the formula below

X = ( ( Mj x Xj ) + ( Mb x Xb ) ) / (Mj + Mb)

X = ( ( 91.2 x 9.99 ) + ( 51.9 x 3.27 ) ) / ( 91.2 + 51.9 )

X =  7.6 m

now when they switch positions their locations now become

John's location (Xj) = + 3.27 m

Barbara's location (Xb) = +9.99 m

now putting their new locations into the formula

X = ( ( 91.2 x 3.27 ) + ( 51.9 x 9.99 ) ) / ( 91.2 + 51.9 )

X =  5.7 m

therefore the center of mass moves by

7.6 - 5.7 = 1.9 m

the center of gravity moves by 1.9 m towards the origin

Answer: D. The flow of an alternating current switches direction when a generator's terminals change its charge.
