Which of the following is the most usable form of energy for future? Energy Business Review lists the world’s most used energy sources based on the share of each source to global energy consumption in the past five decades according to BP’s estimates. Oil has been historically the world’s most used energy source accounting for […]
What is the change in momentum of a 3 kg object accelerating from rest to 12 m s?
What month do geese fly south?
Can you fly through a tornado?
Can you fly through a tornado? Flying through a tornado could destroy an airplane; pilots avoid all thunderstorms — particularly those producing tornadoes — by a wide margin. Is a tornado more dangerous than a hurricane? While both types of storms are capable of producing destructive winds, tornadoes can become stronger than hurricanes. The most […]
How many valence electrons are present in the sodium atom?
How many valence electrons are present in the sodium atom? one valence electron How many valence electrons are present in sodium? Why does sodium have one valence electron? Sodium has one valence electron. The element has a full innermost electron shell of two electrons and a full shell of eight electrons in the next shell. […]
Why did the ball roll when laid on the floor?
Why did the ball roll when laid on the floor? because the friction present between the surface pushes the atoms/particles in contact with surface or ground backwards, hence with centre of mass moving in a direction, the ball’s bottom surface(ie. The surface in contact) moves in opposite direction or backwards, causing the ball to roll. […]
What is the most reliable way to identify a mineral?
What is the most reliable way to identify a mineral? The most reliable way to identify a mineral using color is the streak test. It is more reliable because even though the color of a specimen can vary its streak is usually the same. Which properties are used to identify minerals select 3 choices? Magnetism, […]
Which is more elastic glass or steel?
Which is more elastic glass or steel? The Coefficient of elasticity of glass is between 50 and 90; the Coefficient of elasticity of steel is 210; the Coefficient of elasticity of Copper is 120. Therefore, the rubber is more elastic than glass and glass is more elastic than copper and copper is more elastic than […]
Is it possible for a car to move at constant speed and be accelerating?
Is it possible for a car to move at constant speed and be accelerating? The velocity vector is constant in magnitude but changing in direction. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity […]
What are the basic differences and similarities between a generator and an electric motor What are the basic differences and similarities between a generator and an electric motor?
What are the basic differences and similarities between a generator and an electric motor What are the basic differences and similarities between a generator and an electric motor? Both the motor and generator are similar in construction; they consist of a stator and rotor parts. However, in a motor, electrical energy is the input, while […]
