If f(x)f(x)f(x) is continuous on [a,b][a, b][a,b] and differentiable on (a,b)(a, b)(a,b), then there exists c∈(a,b)c \in (a, b)c∈(a,b) such that f′(c)=f(b)−f(a)b−af'(c) = \frac{f(b) – f(a)}{b – a}f′(c)=b−af(b)−f(a).
Physics
Question: Define Newton’s second law of motion.
Answer:
Newton’s second law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration, F=maF = maF=ma.
Question: What is the formula for kinetic energy?
Answer:
The formula for kinetic energy is KE=12mv2KE = \frac{1}{2}mv^2KE=21mv2, where mmm is mass and vvv is velocity.
Question: Explain Ohm’s law.
Answer:
Ohm’s law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance, I=VRI = \frac{V}{R}I=RV.
Question: What is the speed of light in a vacuum?
Answer:
The speed of light in a vacuum is approximately 3×1083 \times 10^83×108 m/s.
Question: Define the term ‘work’ in physics.
Answer:
Work is done when a force is applied to an object and the object moves in the direction of the force. It is calculated as W=F⋅d⋅cosθW = F \cdot d \cdot \cos\thetaW=F⋅d⋅cosθ.
Question: What is the unit of frequency?
Answer:
The unit of frequency is Hertz (Hz).
Question: Write the formula for gravitational force.
Answer:
The gravitational force is given by F=Gm1m2r2F = G\frac{m_1 m_2}{r^2}F=Gr2m1m2, where GGG is the gravitational constant, m1m_1m1 and m2m_2m2 are masses, and rrr is the distance between them.
Question: Explain the principle of conservation of energy.
Answer:
Energy can neither be created nor destroyed; it can only change from one form to another, but the total energy remains constant.
Question: What is Hooke’s law?
Answer:
Hooke’s law states that the force required to compress or extend a spring is proportional to the displacement, F=−kxF = -kxF=−kx.
Question: Define acceleration.
Answer:
Acceleration is the rate of change of velocity with respect to time, a=ΔvΔta = \frac{\Delta v}{\Delta t}a=ΔtΔv.
