Answer:
Scientific research can promote the raise of the productivity of the society.Which means it can help people produce more goods in a much shorter time and better quality.
From the perspective of a country, if scientific research will not be supported, that country will face a highly pressure and threaten from other counties due to the technology advancement.Technology development will largely determine the military and economic power of a country.
From personally view,our next generation need to be good educated with support.A large part of the area will focus on scientific research,so if we want our children to perform better than us and create a better future.We need to support the scientific research.Nowadays, the AI technology is a very good example that society should support the scientific research. In the long run, we not only benefit from the progress and facility,but we can harvest from the investment into the AI scientific research.
Not the least,scientific research will help human being to know the unknown things in the society,that deep understanding will contribute ourselves to get better way to get along with the new environment and new world.
When the Moon passes through Earth's penumbra, it is a:
a.Solar eclipse
b. Penumbral eclipse
c.Total lunar eclipse
d Partial eclipse
Answer: it is B
Explanation: A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbra. The penumbra causes a subtle dimming of the lunar surface, which is only visible to the naked eye when about 70% of the Moon's diameter has immersed into Earth's penumbra.

A person is standing on ice. He throws a snowball with a force of 4 N to the right, while the snowball pushes the
person with a force of 4 N to the left. What is the net force on the person?
A) 4 N, left
B) 8N
Answer:
A) 4n
Explanation:
He throws a snowball with a force of 4 N to the right, while the snowball pushes the person with a force of 4 N to the left. The given scenario is balanced because the same amount of force is acting in both direction.
The helium-filled balloons below are carrying negative electric charges, as shown. Attach two of the balloons to the hooks below to show what would happen if a red balloon and a blue balloon were brought near each other. Plzz help
Answer:
these are in the hooks the balloons repel each other if the hooks are isolated.
Explanation:
In electrostatics, charges of the same sign repel and of a different sign attract each other.
With this explanation we analyze the situation presented, they indicate that the balloons have a negative taste, so when these are in the hooks the balloons repel each other if the hooks are isolated.
If the hooks are connected to Earth, the poop of the balloons is neutralized, so there is neither attraction nor repulsion.

The speed of sound through diamond is about 12,000 m/s. The speed of sound through wood is about 3,300 m/s. Which statement explains why the speed of sound is different through these materials?(1 point)
They have different rigidities.
They have different temperatures.
They have different phases of matter.
They have different salinities.
Answer: They have different rigidities.
Explanation:
The speed of sound is different through these materials because, they have different rigidities.
What is meant by rigidity of a material ?The property of a material that prevents its shape from changing as a result of an external force is known as rigidity.
Here,
Given that, the speed of sound through diamond is about 12,000 m/s and the speed of sound through wood is about 3,300 m/s.
This is due to the variation in rigidity of the materials through which the sound is travelling.
The stiffness of the medium (or compressibility in the case of gases) and its density work together to define the speed of sound in that medium. The speed of sound increases with the rigidity of the medium. The speed of sound decreases with increasing medium density.
Hence,
The speed of sound is different through these materials because, they have different rigidities.

Why does an iceberg have more HEAT than a cup of coffee.
Explanation:
Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee
Answer:
The hot coffee has a higher temperature, but not a greater internal energy. Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee.

describe tension force (FT) in your own words
Answer In the field of physics, tension is called the force that is exerted by the action of a cable, rope, chain or other similar solid object. ... Since tension is a magnitude of force, it is measured in newtons and is always measured in a direction parallel to the chord on which it is applied.

(11) The speed of radio waves is 300 000 000 m/s.
A radio wave has a frequency of 31 MHZ.
what is wavelength of this radio wave.
Answer:
Wavelength = 9.68 meters
Explanation:
Given the following data;
Speed = 300,000,000m/s
Frequency = 31 Megahertz to Hertz = 31 * 10⁶ Hz
To find the wavelength;
Wavelength = speed/frequency
Wavelength = 300,000,000/31,000,000
Wavelength = 9.68 meters

Explanation:
Consider two less-than-desirable options. In the first you are driving 30 mph and crash head-on into an identical car also going 30 mph. In the second option you are driving 30 mph and crash head-on into a stationary brick wall. In neither case does your car bounce back from the thing it hits, and the collision time is the same in both cases. Which of these two situations would result in the greater impact force on your car?
A. The force would be the same in both cases.
B. Hitting the brick wall.

How do our previous experiences apply to attribution theory?
Answer:
Attribution theory is concerned with how ordinary people explain the causes of behavior and events. ... “Attribution theory deals with how the social perceiver uses the information to arrive at causal explanations for events. It examines what information is gathered and how it is combined to form a causal judgment”. Therefore it is like cause and effect, but just with our feelings and actions.
