Answer:
Doppler effect
Explanation:
this means that at one point when the person running is close to the observer it will appear to run fast but slower as he moves away from the observer
Answer:
Repulsion is the sure test for magnetism because it occurs only when two like poles of a magnet exist while the attraction phenomenon can occur between two unlike poles of a magnet and also between a magnet and a magnetic material means if there are two magnets they will attract each other and suppose if one material
The theory drives this teacher's practices is Behaviorist.
<h3>
Who is a Behaviorist?</h3>
- A methodical approach to analyzing human and animal behavior is called behaviorism.
- It is predicated on the idea that behavior is either a reflex brought on by the combination of specific antecedent stimuli in the environment or a result of the individual's history, particularly reinforcement and punishment contingencies, in conjunction with their current state of motivation and controlling stimuli.
- Although most behaviorists acknowledge the significance of inheritance in affecting behavior, they place a greater emphasis on environmental factors.
- As a response to depth psychology and other traditional forms of psychology, which frequently struggled to make predictions that could be tested experimentally but were derived from earlier research in the late nineteenth century, such as when Edward Thorndike invented the law of effect, behaviorism emerged in the early 1900s.

Question:
In a science class, the teacher sets the room up with a variety of objects such as tubs of water, aluminum foil, and clay. The question on the board is: What makes objects float? Students enter the class and, in small groups, explore the materials. make decisions regarding what data to collect. and discuss the data's meaning. Students are urged to think, ask questions, and draw conclusions on their own. What theory drives this teacher's practices? Select one
A. Behaviorist/Behavioral
B. Humanistic
C. Cognitive
D. Nativist/Innatist
Do you remember the general equation for the distance covered
by a moving object ? There are not many perfect opportunities to
use it in all its glory, but I think this is one of them.
Position =
(starting distance) + (starting speed) (time) + (1/2) (acceleration) (time)²
H = starting position + (starting speed x t) + 1/2 A t²
Here's how we can use it, with some careful definitions:
-- Let's say the surface of the sea is zero height.
Then 'H' ... the position at the end ... is zero, when it plunks into the water, and
the starting, original position of the stone is +10 on the cliff in the man's hand.
-- Starting speed is +5 ... 5 m/s upward, when he tosses it.
-- Acceleration is 9.8 m/s² downward ... the acceleration of gravity.
I think this is going to work out just beautifully !
0 = (5) + 5t - 1/2 (9.8) t²
-4.9 t² + 5t + 5 = 0 That's the whole thing right there. Look how gorgeous that is !
Solve it for 't' with the quadratic equation,
A = -4.9
B = 5
C = 5
When you solve a quadratic with the formula, you always get two roots.
If it's a real-world situation, one of them might not make sense. That's
the result in this case.
The two roots are
t = - 0.622 second
and
t = + 1.642 second
The first one isn't useful, because it means 0.622 second <u>before</u> the man
tossed the stone up.
So our answer is: We hear the 'plunk' <em>1.642 second</em> after the upward toss.
Explanation:
Given that,
We need to find the orbital speed and period of a satellite in orbit 
above Earth.
The formula for the orbital speed is given by :
Let T be the time period of the satellite. It can b solved using Kepler's third law i.e.
Hence, this is the required solution.
