answer with proper explanation
Answer:
B
Explanation:
Moment = force * perpendicular distance
Since the beam is balanced(equilibrium), the 2 moments will be equal.
30 * P = 70 * Q
The 2 combinations which achieve this equality is P = 21 and Q = 9
Which of the following, if eliminated, would completely prevent the greenhouse effect from occurring on earth?
A. Atmosphere Clouds
B. Fossil fuels
C. Acid rain
D. The ozone layer
E. Chlorofluorocarbons
Chlorofluorocarbons is eliminated, would completely prevent the greenhouse effect from occurring on earth.
What is greenhouse effect?The greenhouse effect is a phenomenon in which heat from a planet's host star passes through its atmosphere and warms the surface of the planet, but greenhouse gases in the atmosphere prevent part of the heat from going directly to space, making the world warmer.
Chlorofluorocarbons gas is main cause of greenhouse effect so when we remove it from atmosphere than green house effect will be reduced.
Chlorofluorocarbons is eliminated, would completely prevent the greenhouse effect from occurring on earth.

If a piece of glass permits light to pass through, then it is considered ___________. A. Transparent c. Transmitting b. Reflective d. Absorbent Please select the best answer from the choices provided A B C D.
Answer:
not sure, but I thinks it's either Transparent or Reflective
According to the concept of reflection, if a piece of glass permits light to pass through, then it is considered to be reflective.
What is reflection?Reflection of light is defined as a property of light ray that when it strikes a smooth surface it bounces back .Objects can be seen due to this property of light.Reflection is produced by all types of waves namely sound waves, light waves, electromagnetic waves.
Reflection of light is governed by laws of reflection which are also called as Snell's laws. According to laws of reflection, angle of incidence and angle of reflection are equal.The incident ray , reflected ray and normal all lie on the same side of the plane.Light travels in a straight line before, after and during the process of reflection.There are 3 types of reflection which are diffuse reflection,specular reflection and glossy reflection.

Let's consider the given terms ~
Initial velocity (u) = 100 m/sAcceleration (a) = - 10 m/s²(Acceleration is negative bbecause train slows down)
Final velocity (v) = 0 m/s(final velocity is 0, because train stops)
Now, let's find the time taken (t) by using the first equation of motion ~
[tex]v = u + at[/tex][tex]0 = 100 + ( - 10 \times t)[/tex][tex]0 = 100 - 10t[/tex][tex]10t = 100[/tex][tex]t = 100 \div 10[/tex][tex]t = 10[/tex]The train will take 10 secs to stop,
Now, let's find how much distance (s) it will cover before it stops using second equation of motion ~
[tex]s = ut + \dfrac{1}{2} at {}^{2} [/tex][tex]s = (100 \times 10) + ( \dfrac{1}{ 2} \times - 10 \times 10 \times 10)[/tex][tex]s = 1000 + ( - 500)[/tex][tex]s = 1000 - 500[/tex][tex]500 \: \: m[/tex]It will cover 500 meters before coming to rest ~
Mention the methods of census and explain each of them in brief
Answer:
Census includes the total process of collecting, compiling, analyzing, evaluating, publishing and disseminating statistical data regarding the population and housing and their geographical location. Population characteristics include demographic, social and economic data and are provided as of a particular date (reference period).
Census Methods:
Population censuses typically use one of two approaches:
De facto – meaning enumeration of individuals as of where they are found in the census, regardless of where they normally reside.
De jure - meaning enumeration of individuals as of where they usually reside, regardless of where they are on census day.

A car approaches you at 50 km/h. A fly inside the car is flying toward the back of the car at 7 km/h. From your point of view by the side of the road, the fly is moving at ______________km/h. Group of answer choices 57
Answer:
43 km/h
Explanation:
If the car is going past you at 50 km/h, then all the objects inside appear to be going 50 km/h. The fly is flying 7km/h in the opposite direction, and would appear to be going 7 km/h slower. Therefore, as 50 - 7 is 43, the fly would appear to be going 43 km/h. Hope this helps :D
A 68 g plastic ball is moving to the left at 17 m/s . How much work must be done on the ball to cause it to move to the right at 17 m/s ?
Answer:
KE = 19.652 J to the right
Explanation:
KE = J or N*m
KE = (1/2)m*v²
KE = kinetic energy
m = mass(kg)
v = velocity (m/s)
KE = .5*0.068kg*(17m/s)²
KE = 9.826 J to the left
So double it to the right to get 17m/s.
KE = 19.652 J to the right
J = Joules or can be expressed as N*m which is Newton-meters.

The temperature rise in the copper is. I think its 0.393. Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29.
What is Capacity of copper?The chemical element copper (Cu) is a reddish, incredibly ductile metal belonging to Periodic Group 11 (Ib) that has an exceptional ability to conduct heat and electricity.
In nature, copper can be found in its free metallic state. Neolithic (New Stone Age) humans originally utilised this local copper (about 8000 BCE) as a substitute for stone.
Around 4000 BCE, Mesopotamia saw the beginning of metallurgy as copper was cast into molds, reduced to metal from ores with fire and charcoal, and purposefully alloyed with tin to form bronze (c. 3500 BCE).
Therefore, The temperature rise in the copper is. I think its 0.393. Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29.

Which type of wave requires a medium?
A. Light wave
B. Electromagnetic wave
C. Sound wave
D. Ultraviolet wave
The correct answer is option C. Sound wave
A sound wave is an example of a mechanical wave which requires a medium.
Answer:
The closest is “A”, however an ocean wave is not truly a transverse wave. It belongs to the category “gravity wave” (note: NOT gravitational wave as in cosmology) and occur at the interface between two media. In the case of a wave on the ocean surface it is specifically called a “surface gravity wave” . The particles in a surface gravity wave move in an oscillatory circular motion called the wave orbit not in a back and forth motion.
