The ROOF and the walls of an auditorium or cinema hall are generally COVERED with sound-absorbent MATERIALS LIKE draperies or COMPRESSED fiberboard to reduce the effect of reverberation. These materials reduce the formation of echoes by absorbing the sound waves

Socrates is considered by many the FATHER of philosophy. He liked asking questions and QUESTION everything (which ultimately COST him his life by the way). ... When people attributed events to the Gods, Socrates disagreed and tried to PERSUADE everyone that there should be a logical and REASONABLE.

James Prescott JOULE STUDIED the NATURE of heat and established its relationship to mechanical work. He laid the foundation for the theory of conservation of energy, which later influenced the First Law of THERMODYNAMICS. He also formulated the Joule's law which DEALS with the transfer of energy.

Yes, if the angle between the vectors is 120 degrees. In this situation, the two vectors and their SUM (resultant) will form an EQUILATERAL triangle.Explanation:According to the QUESTION,R=A=√A^2+A^2+2A.Acosθ​A^2=A^2+A^2+2A.AcosθA^2=2A^2+2A^2cosθ1=2(1+cosθ)1+cosθ=1/2​cosθ=−1/2​=−0.5θ=cos−1(−0.5)θ=120°

622.22Explanation:

The FIRST law of thermodynamics can be simply STATED as follows: during an INTERACTION between a system and its surroundings, the AMOUNT of energy gained by the system must be exactly equal to the amount of energy LOST by the surroundings. ... This is the first law of thermodynamics for a closed system undergoing a cycle.

Implied powers are political powers granted to the United States government that aren't explicitly stated in the Constitution. They're implied to be granted because SIMILAR powers have set a PRECEDENT. These implied powers are necessary for the function of any given GOVERNING body.Explanation:please MAKE the BRAINLIAST Answer please buddy

Explanation:First Object: Mass (m₁) = 5 kg Initial Velocity (u₁) = 0 m/s Final velocity (v₂) = 16 m/s time = 5 s We know that, Force = mass * acceleration And acceleration = (v - u) / t. Hence, F₁ = 5 * (16 - 0) / 5 → F₁ = 5 * 16/5 → F₁ = 16 N SECOND Object: Mass (m₂) = 8 kg Initial Velocity (u₂) = 0 m/s Final Velocity (v₂) = 15 m/s Time = 5 s Hence, F₂ = 8 * (15 - 0) / 5 → F₂ = 8 * 15/5 → F₂ = 24 N Additional Information: Force: It is the push or pull of an Object. It is a vector quantity. It is DENOTED by "F". F = ma, where m is the Mass of the Object and a is it's acceleration. It's units are Newtons (N) and dynes (dyn). It depends on mass & acceleration of the object.

tion:(a) INITIAL velocity of ball (u)=50m/s, ACCELERATION of ball =−g,FINAL velocity at the highest point (v)=0So applying the 3rd equation of motion we get:v 2 =u 2 −2gh max ⇒0=50 2 −2×10×h max ⇒h max = 202500 =125m(B) Let the time required to reach max height be t. Then applying 1st equation of motion we get:v=u−gt⇒0=50−10t⇒t=5s(c) Let SPEED at half of max height be V then:V 2 =50 2 −2g 2125 ⇒V 2 =2500−1250=1250⇒V= 1250 =35.35m/s.

Heat can travel from one place to another in THREE ways: CONDUCTION, Convection and RADIATION. Both conduction and convection require matter to transfer heat. If there is a TEMPERATURE difference between two systems heat will ALWAYS find a way to transfer from the higher to lower system.

2.45E1here's the ANSWER

LAW OF CONSERVATION OF ENERGY ENERGY CAN NEITHER BE CREATED NOR BE DESTROYED.

Horizontal force,F=600 NMass of body A, m 1 =10 kgMass of body B, m2=20 kgTotal mass of the system, m=m1+m2=30 kgUsing Newtons second law of MOTION, the acceleration (a) produced in the system can be calculated as:F=ma a= mF = 30600 =20m/s 2 When force F is applied on body A:The EQUATION of motion can be written as: F−T=m 1 aT=F−(m 1 )a =600−10×20=400 N (i)When force F is applied on body B: The equation of motion can be written as: F−T=m 2 a T=F−(m 2 )aT=600−20×20=200 N (ii)which is DIFFERENT from value of T in case (i). Hence our answer depends on which mass end, the force is applied.

A power limit is an upper (lower) bound on power produced (CONSUMED) in the system. To FIND the power limit CUMULATIVE power is maximized for the system containing a fluid, an ENGINE or a sequence of engines, and an infinite BATH. Reversible relaxation of the resource leads to the classical exergy.

These tactics are ways in which individuals translate power bases into specific actions. ... The 9 INFLUENCE tactics are legitimacy, RATIONAL persuasion, INSPIRATIONAL appeals, CONSULTATION, exchange, PERSONAL appeals, ingratiation, pressure and coalitions.

Joule, CALORIE, eV, KILOWATT hour; all are the units of energy. Watt is not the unit of energy. It is the SI unit of electric POWER. Power is defined as the RATE of doing work.

There are 6 superpower characteristics! (Economic, Political, MILITARY, CULTURAL, Demographic, Natural Resources), used to define which TYPE of power a country is.

The radius of curvature of a SPHERICAL MIRROR is 20 cm. What is its focal length? Therefore, the focal length of the spherical mirror is 10 cm.

nfo : A pump on the ground floor of a BUILDING can pump up WATER to fill a tank of volume 30 m³ in 12 min. If the tank is 40 m above the ground, and the efficiency of the pump is 40%. To find : how MUCH electric POWER is consumed by the pump ? solution : mass of water pumped up to fill the tank , m = volume × density of water = 30 m³ × 1000 kg/m³ = 30,000 kg height of the tank from the ground, h = 40 m so potential energy of water, U = mgh = 30,000 kg × 10 m/s² × 40 m = 12 × 10⁶ J power required to pump up water = (Energy/time) = 12 × 10⁶/12 × 60 W = (1/60) × 10⁶ W but efficiency of motor is 40 % so, electric power consumed by motor = Power required to pump up water × 100/40= (1/60) × 10⁶ × 100/40 W = 41.67 kW Therefore electric power consumed by the pump is 41.67 kW

Open the door. If the LIGHT is on, then switch number 2 controls it. If the light is off, then go and feel the bulb with your hand. If the bulb is hot, then switch number 1 controls it, and if the bulb is COLD, then switch number 3, the one you did not touch, controls it.Explanation:

I have always been trying to understand and visualize what wave is and how it's been produced. I GUESS what ordinary people KNOW about wave is just a particle moving up and down but last week I came ACROSS this IMAGE that titled “how particles produce Wave”. According to this image, the interaction between particles and how close they got produces wave, in other words, a single particle cannot produce wave. Particles PRODUCING wave
