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.

Why does the value of g is move at polar region than at equator
Explanation:
the centrifugal force of the Earth's rotation forces the Earth's belly at the equator to grow even further. that extra material/mass is pulled in from the poles.
so, from equator to equator there is more mass and more gravity than from pole to pole.

Answer:
Ever since the discovery of Pluto in 1930, kids grew up learning that the solar system has nine planets. That all changed in the late 1990s, when astronomers started arguing about whether Pluto was indeed a planet. In a highly controversial decision, the International Astronomical Union ultimately decided in 2006 to designate Pluto as a "dwarf planet," reducing the list of the solar system's true planets to just eight.

Give reason Pascal is a derived unit
Answer:
Pascal is a derived unit because it cannot be expressed in any physics terms, but it is an expression of fundamental quantities.
Explanation:
[tex]{ \sf{Pasacal \: ( Pa) = \frac{newtons}{metres {}^{2} } }} \\ \\ { \sf{Pasacal \: (Pa) = \frac{kg \times {ms}^{ - 2} }{ {m}^{2} } }}[/tex]
If river flowing at 9km/h,how to find boats velocity?
Answer:
Flow rate and velocity are related by Q=A¯v where A is the cross-sectional area of the flow and v is its average velocity.
7. Two billiard balls of equal mass, one blue and the other red, slide towards each other at 2.0m/s in opposite
directions towards each other. They collide head on and rebound both at 1.8m/s in opposite to their original
velocities,a s shown in the diagram below. Show how momentum is conserved in this collision.
Answer:
P = M V expresses momentum
Both before and after collision the momenta are equal and in opposite directions. So the the total momentum is zero both before and after the collision. P is a vector quantity as is the velocity. Total momentum must be zero.
the mass of an object is 45 kg and it has a density of 5 gram per centimetre cube what is the volume
Density = Mass/Volume
=> 5g/cm³ = 45kg/Volume
=> 0.005kg/cm³ = 45kg/Volume
=> Volume = (cm³×45kg)/0.005kg
=> Volume = 9000kg/cm³
5 grams fits into 45 kg 9,000 times.
Since each 5 grams occupies 1 cm³, 9,000 little packages of 5 grams must occupy 9,000 cm³ . (That's 9 liters.)

An object has a kinetic energy of 8.8J and a mass of 450g. How fast is the object moving?
Answer:
Explanation:
The formula for KE is
[tex]KE=\frac{1}{2}mv^2[/tex] We have everything we need to solve for the velocity, but we first have to convert the mass from grams to kg:
450 g = .450 kg
[tex]8.8=\frac{1}{2}(.450)v^2[/tex] and we'll rearrange that and solve it for v before we do any math:
[tex]v=\sqrt{\frac{2(8.8)}{.450} }[/tex] so
v = 6.3 m/s rounded to the correct number of sig fig's

A substance freezes at 25 degree celcius and boils at450 degree celcius at what temperature will the subsancehave a definate shape and a defnate volume
Answer:
solid
Explanation:
I really don't know
Answer:
In Sections 1.3 and 2.5A3, we noted that the physical properites of a particular substance determine its state at room temperature. If both its normal melting point and its normal boiling point are below room temperature (20°C), the substance is a gas under normal conditions. The normal melting point of oxygen is -218°C; its normal boiling point is -189°C. Oxygen is a gas at room temperature. If the normal melting point of a substance is below room temperature, the substance is a liquid at room temperature. Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid. Sodium chloride melts at 801°C and boils at 1413°C. Sodium chloride is a solid under normal conditions. Figure 9.1 illustrates the relationship between physical state and normal melting and boiling points.
