Answer:
Earth's axis is tilted relative to its orbital plane.
Earth orbits around the Sun, completing one orbit each year
Explanation:
The earth tilt at an angle causes the sun rays to hit the earth surface around the globe differently. Due to the oblique angle that the rays hit the subtropics and poles, there is less heat intensity compared to the equator where the sun rays hit the earth's surface at a more or less right angle.
The earth rotation around the sun also causes seasons coupled with the earth’s tilts. As the earth rotates, in one point in the orbit, the northern or southern hemispheres will be tilted towards the sun. The phenomenon varies the local temperatures of particular regions of the earth hence driving seasonal climatic changes.
Answer:
(Downwards)
(Towards Left)
Explanation:
As we know that beam is in equilibrium
So here we can use torque balance as well as force balance for the beam
Now by torque balance equation at the pivot we can say
As we know that
mg = 1.40 kN
F = 5 kN
so we will have
Now force balance in vertical direction
(Downwards)
Force balance in horizontal direction
(Towards Left)
Explanation:
The waveform expression is given by :
...........(1)
Where
y is the position
t is the time in seconds
The general waveform equation is given by :
..........(2)
Where
On comparing equation (1) and (2) we get :
f = 93.10 Hz
Time period, 
T = 0.010 s
Phase constant, 
Hence, this is the required solution.

Think of inertia of getting into a car accident without a seat belt although the car stops you will not you would likely fly out the window
Answer:
Janet stops parking in handicapped spaces after she gets a big parking ticket. - Positive Punishment
Peter’s recess is taken away to discourage him from getting into fights with the other children. - Negative Punishment
Ted increases paying his bills on time to avoid a late fee. - Negative Reinforcement
Sally increases the amount of work she completes to receive more pay. - Positive Reinforcement
Explanation:
In operant conditioning, the main principle is that behavior increases or decreases its frequency depending on whether it's reinforced or punished. A behavior can be reinforced by giving something the subject appreciates, like more pay for their work (positive reinforcement) or taking away something they dislike, like late fees (negative reinforcement). Punishments work the same way, you can give something the subject dislikes, like a parking ticket, (positive punishment) or taking away something they like recess for a child. (negative punishment).
