Pressing a lever in the box's corner is the sole method to get rid of the shocks. The rat picks up pressing the lever quite quickly. This is an illustration of negative reinforcement.
What is negative reinforcement?The technique of negative reinforcement can be applied to aid in teaching particular actions.
When something unpleasant or uncomfortable is taken away in response to a stimulus, this is known as negative reinforcement.
Target behavior should gradually grow better with the hope that the unpleasant item will go away.
A rat is placed in an environment where the floor gives the rat small electric shocks. The only way to get rid of the shocks is to press a lever in the corner of the box.
The rat quickly learns to press the lever. This is an example of negative reinforcement
Hence the given condition is an example of negative reinforcement.

What the suns mass in scientific notation????
Explanation:
In scientific notation the Sun's mass is: =1.989 x 10 ^30 kg
Answer:
I think in scientific notation the Sun's mass becomes: M Sun = 1.989 x 10 30 kg. The number above the ten, called the power of ten or exponent, stands for the number of decimal places. If it is positive, as in the mass of the Sun, the decimal places are in front of the decimal point.

what will be the gravitational force between two bodies if the mass of each is doubled and the distance between them is halved?
Answer:
Gravitational force will be 16 times more.
Explanation:
we know;
Gravitational force (F) = (Gm1m2)/d^2
when mass of each is doubled and distance between them is halved;
F= (G2m1×2m2)/(d/2)^2
=(4Gm1m2)/(d^2/4)
=4×4(Gm1m2)/d^2
=16(Gm1m2)/d^2
=16F
A 210 Ohm resistor uses 9.28 W of
power. How much current flows
through the resistor?
(Unit = A)
Current=I
[tex]\boxed{\sf P=I^2R}[/tex]
[tex]\\ \sf\longmapsto I^2=\dfrac{P}{R}[/tex]
[tex]\\ \sf\longmapsto I^2=\dfrac{9.28}{210}[/tex]
[tex]\\ \sf\longmapsto I^2\approx0.04[/tex]
[tex]\\ \sf\longmapsto I\approx\sqrt{0.04}[/tex]
[tex]\\ \sf\longmapsto I\approx\sqrt{\dfrac{4}{100}}[/tex]
[tex]\\ \sf\longmapsto I\approx\dfrac{\sqrt{4}}{\sqrt{100}}[/tex]

if vector A=2i+3j-k and vector B=4i+6j-2k. The angle between them will be: a) 0°b)45°c)90°d)60°
Notice that
B = 4i + 6j - 2k = 2 (2i + 3j - k) = 2A
so both vectors point in the same direction and the angle between them is (A) 0°.
There is no centripetal force if the object moves in a long line. True or False?
Answer:
true
Explanation:
i think it's true because according to newtons first law of motion an object continues in motion unless compelled by an external force, this external force is known as the centripetal force.

How does mercury differ from other metals?(1 point)
It does not conduct electricity.
It is not lustrous.
It is not solid under normal conditions.
It does not chemically react with other elements.
Answer:
It is not solid under normal conditions
Mercury differs from other metals as It is not solid under normal conditions. It is the only metal that is liquid at room temperature, therefore the correct answer is option C
What is the matter?Anything which has mass and occupies spaces is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
These different states of matter have different characteristics according to which they vary their volume and shape.
Because it is not solid under normal circumstances, mercury is different from other metals. Because it is the only metal that is liquid at room temperature,
Thus the correct answer is option C

How does the temperature of a planet determine the states of matter you would observe on that planet?
Explanation:
the temperature will determine the kinetic energy or degree of freedom of the molecules of matter.
if the temperature is high, the kinetic energy of the molecules increase which may cause a change of state into a gas which has molecules of high kinetic energy. this shows that temperature is a measure of the kinetic energy of the molecules.

2. State Newton's third law of motion.
Answer:
Action and reaction are equal but act in opposite directions
Answer:
Newton’s third law of motion states that “ for every action there is always an equal and opposite reaction.”
Explanation:
If body A exerts a force on body B, then body B will exert an equal and opposite force on body A. It is also called action reaction force. They have equal magnitude but are opposite in direction.

what happens when a force is applied in the direction of motion of a body
Answer:
If the force applied on the object is in the direction of its motion, the speed of the object increases. If the force is applied in the direction opposite to the direction of motion, then it results in a decrease in the speed of the object.
