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 […]
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 are the most important properties of a star?
What are the most important properties of a star? Mass – The single most important property that determines other properties of the star. Luminosity – The total amount of energy (light) that a star emits into space. Temperature – surface temperature, closely related to the luminosity and color of the star. What does the color […]
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 […]

What is Sun in simple words? The Sun is […]
Did Newton agree with Galileo?
Did Newton agree with Galileo? Galileo determined the laws of gravity and explored the laws of motion on earth. Newton first conclusively affirmed the laws of motion and linked them with Kepler’s laws of planetary motion. Galileo had suggested this, but was censored by the Church before he was able to do further work to […]
Do bulbs in series have the same brightness?
Do bulbs in series have the same brightness? Placing cells in series increases the voltage in the circuit by 1.5 V for each cell. Increasing the number of bulbs in a series circuit decreases the brightness of the bulbs. In a series circuit, the voltage is equally distributed among all of the bulbs. Bulbs in […]
What is flux in electric field?
What is flux in electric field? Electric flux, property of an electric field that may be thought of as the number of electric lines of force (or electric field lines) that intersect a given area. The negative flux just equals in magnitude the positive flux, so that the net, or total, electric flux is zero. […]
What can a firewall not prevent?
What can a firewall not prevent? Users not going through the firewall: A firewall can only restrict connections that go through it. It cannot protect you from people who can go around the firewall, for example, through a dial-up server behind the firewall. It also cannot prevent an internal intruder from hacking an internal system. […]
