Explanation:
(1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.
A shift inward of the production possibilities curve signifies that _
A. The demand for the products has increased, so the supply will increase
B. The available resources have increased, so potential production levels will increase
C. The available production resources have decreased, so potential production levels will decrease
D. The demand for the products has decreased so, the supply will decrease
Answer:
c
Explanation:
A shift inward of the production possibilities curve signifies that: C. The available production resources have decreased, so potential production levels will decrease.
A production possibilities curve (PPC) is also referred to as production possibilities frontier (PPF) and it can be defined as a curve that illustrates the maximum (best) combinations of two (2) products which can be produce in an economy if they both depend on these two (2) main factors;
Fixed technology. Fixed resources.Basically, the production possibilities curve (PPC) illustrates the maximum combinations of goods that are available with fixed technology and resources.
Furthermore, an inward shift of the production possibilities curve (PPC) signifies that the available resources used for production have decreased, so potential production levels would also decrease.

Describe a procedure the student could use with the lab setup shown in order to determine the average velocity of the marble as it travels down the inclined ramp. Include what variables would need to be measured and how to measure them.
Variables - Initial position, Final position, Distance between Positions, Time.
Instruments - Ruler (Distance between Positions), Chronometer (Time)
Average Velocity is equal to the change in Position divided by Time. Since Incline is a Straight Line, then Position Change and Traveled Distance are the same. In this case, we need to define Initial and Final Position of the marble, and then we have to measure the distance between these Points.
Distance between Initial and Final Position can be measured by a Ruler, whereas Time can be measured by a Chronometer.
In a nutshell, Initial and Final Position and Time are variables needed to be measured. Besides, Distance between Initial and Final Position can be found by means of a Ruler, and Time is found with the help of a Chronometer.

Which statement is true?
A. When a gas condenses to a liquid, it absorbs energy.
B. When water boils, it releases energy.
C. When ice melts, it absorbs energy.
D. When water freezes, it absorbs energy.
Explanation:
The correct answer is option B
Answer:
C. When ice melts, it absorbs energy.
Explanation:
When ice melts, it is getting hotter by absorbing energy and changes from a solid to a liquid. This is an endothermic reaction.

Adam is driving his truck at 18 m/s for a distance of 46 m, how much time was Adam driving?
Answer:
2.6 seconds
Explanation:
You have to divide the distance by the velocity to find the time:
46/18 = 2.55 ≈ 2.6 seconds
The answer you are looking for is approximately 2.6 seconds.
Solution/Explanation:
To get the correct answer, you must divide the distance and velocity.
This means that 46÷18=2.5556.
2.5556≈2.6.
So, therefore, the final answer is approximately 2.6 seconds.

Waves are created on the surface of water when we drop a stone into it. Similarly you must have seen the waves generated on a string when both its ends are held in hand and it is shaken. Light is also a type of wave called the electromagnetic wave. Gamma rays, X-rays, ultraviolet rays, infrared rays, microwave and radio waves are all different types of electromagnetic waves. Astronomical objects emit these waves and we receive them using our instruments. All our knowledge about the universe has been obtained through these waves. Gravitational waves are a very different type of waves. They have been called the waves on the fabric of space-time. Einsteine predicted their existence in 1916. These waves are very weak and it is very difficult to detect them. Scientists have constructed extremely sensitive instruments to detect the gravitational waves emitted by astronomical sources. Among these, LIGO (Laser Interferometric Gravitational Wave Observatory) is the prominent one. Exactly after hundred years of their prediction, scientists detected these waves coming from an astronomical source. Indian scientists have contributed significantly in this discovery. This discovery has opened a new path to obtain information about the Universe. i. Which type of wave a light ray is ? (1 marks) ii. What type of rays are Gravitational waves called ? (1 marks) iii.

I just need a little starter for this paragraph!
Answer:
The north part of the compass needle is attracted to the magnetic south pole of Earth, which is also known as the geographical north pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
