Answer:
1. Gravity
2. Increases
Explanation:
Gravity is the force that attracts all objects toward each other. This is the force that keeps us grounded on Earth instead of floating in the air.
Although people have gravitational forces, the attraction force is a negligible amount. However, as the mass of the objects are increased, they will exert far greater gravitational powers to other objects or individuals such as humans.
Answers A and C can be automatically eliminated because evaporation has to do with the water cycle and magnetism has to do with electric current and such. Next we can eliminate B or distillation because it also has to do with water/liquids. Therefore, the answer is D or filtration because it is the only answer left.
I hope this helps!
Through de Broglie's hypothesis, we can express the relationship between a particle's wavelength and momentum through the equation below.
where h is the Plank's constant equivalent to 6.626 x 10⁻³⁴ J.s. Recall that momentum, p, can be computed as
p = mv
where m is the mass and v is the velocity of the particle. Now, we have a rock with a mass of 60.0 g or 0.06 kg and a velocity of 40.0 m/s. Now, its de Broglie wavelength is
Therefore, the rock's de Broglie's wavelength is 2.761 x 10⁻³⁴ m.
Answer: 2.761 x 10⁻³⁴ m
Answer:
Height of mirror will be 1 m for complete image of person
Explanation:
We have given distance of person from plane mirror d = 2 m
And height of person = 2 m
We have to find the height of plane mirror which given full image of person
Height of mirror will be equal to half of height of person
So height of mirror
So height of mirror will be 1 m for complete image of person
Answer:
Explanation:
For very low values of the ionic strength the value of the denominator in the expression above becomes nearly equal to one. In this situation the mean activity coefficient is proportional to the square root of the ionic strength. This is known as the Debye–Hückel limiting law.
