Write a brief summary of table tennis or tennis
Answer:
A point is won by a player when the opponent cannot hit the ball with a racket over the net and onto the other side of the table. Each game is won by being the first player to win 11 points, and be at least 2 points ahead of their opponent. The equipment needed to play table tennis would be a table, rackets, and balls. Some of the rules are no hand-on table (even leaning your hands on the table is not allowed!) Also, if the ball hits the net, you have to serve again.
What disagreement did Sigmund Freud have with both Josef Breuer and Jean Martin Charcot?
A. whether hypnosis was a neurological or psychological phenomenon
B. whether hypnosis should be conducted with pregnant women
C. whether hypnosis had any value as a curative remedy for patients
D. whether hypnosis was an effect of a "hidden observer" or the id
Answer:
The correct answer is 'A'
Explanation:
I guessed and was correct.
Freud backed Bernheim's efforts to establish hypnosis and suggestion as acceptable fields of study for science and to advance them as therapeutic tools. Thus, option A is correct.
What is the neurological or psychological phenomenon?Both neurologists and psychiatrists treat illnesses and ailments that affect the brain and the psyche. However, while psychiatrists focus on psychological issues, neurologists are experts in physiological illnesses.
According to medical terminology, neurological disorders are conditions that impact the spinal cord, brain, and body's nerves.
A variety of symptoms can be caused by structural, metabolic, or electrical abnormalities in the brain, spinal cord, or other nerves.
Therefore, whether hypnosis was a neurological or psychological phenomenon.

Why does sonar use ultrasound rather than sound?
Answer; Ultrasonic waves (sounds having frequency greater than 20,000 Hz) are used in sonar because: ... Ultrasonic waves can penetrate water to long distances (because of their high frequency and very short wavelength), but ordinary sound waves or infrasonic waves cannot penetrate water to such long distances.

Mass refers to the gravitational force on the matter in contact with the surface of a planet. true or false
Answer:
False
Explanation:
The mass of something does not depend on gravity. A planet has a constant gravitational force. Earth's is 9,80 N/kg. The moon, on the other hand, is 1,6 N/kg. the number of kilograms of something doesn't change if you go from one planet to another and since mass is measured in kilograms, mass doesn't change, therefore it does not refer to gravity. Mass refers to the quantity of matter in an object. It is weight that refers to the gravitational force on an object, since it is measured in newtons, and the amount of newtons per kilogram changes from planet to planet due to different gravity constants
A. 2kg
B. 6kg
C. 8kg
D. 14kg
Answer:
A
Explanation:
We know the force is (16N-12), which is 4N, and we know the acceleration is 2 m/s^2. Meaning, we can solve the formula m = F / a (mass equals force divided by acceleration), and we get 2kg.

Why do oil tankers sit lower in water
When a lower tank is damaged, the incoming sea water pushes the oil in the damaged tank up into the ballast tank. Because of the hydrostatic pressure, there is an automatic transfer out of the damaged tank. The double-hull design is aimed at the probability of zero outflow.

ok the answer for number 14 is 0.5 0 kilograms to get this answer this is my explanation ok where try that the bottle of water when full has a mass of 1.30 kg and one half of the water is poured away the mass of the bottle and the half of water is 0.90 kilograms so to get the the water that was poured out we will subtract 0.90 kg from 1.30 kilograms to get 0.40 kilograms so this 0.40 kilograms is the half of the water that was poured out meaning the other half is also 0.40 so to get the mass of the bottle we will take mass of the bottle plus the water - mass of the water so it will be 1.30 kilograms - 0.80 kilograms to get 0.50 kilograms.and number 15 I don't know I'm sorry about thatplease help

Ben has two carts with masses of 0.1 kg and 0.2 kg. He pushes the smaller cart toward the larger cart and they collide. The smaller cart rebounds back in the direction it came from. He measures the force on the smaller cart from the larger cart to be 5 N. What was the magnitude of the acceleration of the smaller cart?
Answer:
The acceleration of the smaller cart is 50 m/s²
Explanation:
The given masses of the carts are 0.1 kg and 0.2 kg
The direction in which the small cart bounces = In the revers to its initial direction
The force exerted by the larger cart on the small cart = 5 N
Therefore, we have;
Force acting on smaller cart = Mass of smaller cart × Acceleration of the smaller cart
∴ The acceleration of the smaller cart = Force acting on smaller cart/(Mass of smaller cart)
The acceleration of the smaller cart = 5 N/(0.1 kg) = 50 m/s²
The acceleration of the smaller cart = 50 m/s².

What is the name of the kind of stretch that involves stretching as far as you can and then holding for 10-30 seconds
Question 2 options:
PNF
ballistic
dynamic
static
Answer:
Static stretching.
Explanation:
It is static stretching because it is a form of stretching which u can do actively for a period of time and you hold position for about 30 to 60 seconds which allow the muscles and connective tissues to lengthen. It is done after work out with out movement in order to loosen up muscles so as to gain flexibility.
If I travel at a velocity of 2m/s to the right for 4 seconds, what is my displacement?
Carlos gets tired of pushing and instead begins to pull with force Fpull at an angle to the horizontal.
The block slides along the rough horizontal surface at a constant speed. A free-body diagram for the
situation is shown below. Blake makes the following claim about the free-body diagram:
Blake: “The velocity of the block is constant, so the net force exerted on the block must be zero.
Thus, the normal force FN equals the weight Fmg, and the force of friction Ff equals the applied
force Fpull.”
What, if anything, is wrong with this statement? If something is
wrong, identify it and explain how to correct it. If this statement is
correct, explain why.
Answer:
The wrong items are;
1) The normal for FN equals the weight Fmg
2) The force of friction, Ff, equals the applied force Fpull
The corrected statements are;
1) The normal force is weight less the vertical component of the applied force Fpull
FN = Fmg - Fpull × sin(θ)
2) The force of friction equals the horizontal component of the applied force Fpull
Ff = Fpull × cos(θ)
Explanation:
The given statement was;
The velocity of the block is constant, so the net force exerted on the block must be zero. Thus, the normal force FN equals the weight Fmg, and the force of friction Ff equals the applied force Fpull
By the equilibrium of forces actin on the system, given that the applied force acts at an angle, θ, with the horizontal, we have;
The normal force is equal to the weight less the vertical component of the applied force;
That is we have, FN = Fmg - Fpull × sin(θ)
The friction force similarly, is equal to the horizontal component of the applied force;
Ff = Fpull × cos(θ)
The wrong items are therefore as follows;
1) The normal for FN equals the weight Fmg
1 i) The normal force is weight less the vertical component of the applied force Fpull
FN = Fmg - Fpull × sin(θ)
2) The force of friction, Ff, equals the applied force Fpull
2 i) The force of friction equals the horizontal component of the applied force Fpull
Ff = Fpull × cos(θ).
a pulling force carried by a rope is called what
Answer:
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
Explanation:
What distance is required for a train to stop if its initial velocity is 23 m/s and its
deceleration is 0.25 m/s²? (Assume the train decelerates at a constant rate.)
-- The train starts at 23 m/s and slows down by 0.25 m/s every second.
So it'll take (23/0.25) = 92 seconds to stop.
-- Its average speed during that time will be (1/2)(23+0) = 11.5 m/s
-- Moving at an average speed of 11.5 m/s for 92 sec, the train will cover
(11.5 m/s) x (92 sec) = 1,058 meters .
The distance required for the train to travel before stopping is 1,058 m.
The given parameters;
initial velocity of the train, u = 23 m/s
deceleration of the train, a = 0.25 m/s
The distance traveled by the train is calculated as follows;
[tex]v^2 = u^2 -2as[/tex]
where;
v is the final velocity of the train
The final velocity of the train is zero when the train stops
[tex]v^2 = u^2 -2as\\\\0 = 23^2 - 2(0.25)s\\\\0.5s = 529\\\\s = \frac{529}{0.5} \\\\s = 1,058 \ m[/tex]
Thus, the distance required for the train to travel before stopping is 1,058 m.
