It states that, "If a stress is placed on a system on equilibrium whereby the equilibrium is altered, that change will take place which tends to relieve or neutralize the effect of the added stress".

At the boiling point of liquid, the vapor pressure

Suppose that energy Q is required to accelerate a car from rest to v, neglecting friction. How much added energy would be required to increase the speed from v to 2v?

Who determined the quantitative relationship between the amount of electricity used in electrolysis and the amount of chemical reaction that occurs?

Which of the following thermometers is best suited for measuring a temperature of nearly 1500oC?

At what temperature do both the centigrade and Fahrenheit thermometers show the same reading

A mass of 8 kg is above a given datum, where local g is 9.70 m/s^2. Calculate the gravitational force with respect to the datum?

A spaceship moving away from Earth with speed of 0.900c fires a robot space probe in the same direction as its motion, with speed of 0.700c relative to the spaceship. What is the probe’s velocity relative to the Earth?

A person’s mass is 75.2 kg. If the person walks up a flight of stairs 12.6 m high in 28 s at constant velocity, what is the power output?

It describes the luminous flux incidence per unit area and is expressed in lumens per square meter.

In fluid mechanics, this shows that the pressure of a fluid decreases as the speed of the fluid increases. In addition, the pressure of a fluid decreases as the elevation increases

“At any point along a streamline in an ideal fluid in steady flow, the sum of the pressure, the potential energy per unit volume and the kinetic energy per unit volume have the same value.” The concept is known as

The surface of the thermos flask is silvered for minimizing heat transfer by what process

The work done by all forces except the gravitational force is always equal to the one of the system

Material a is a water and material b is a glass with index of refraction 1.52. If the incident ray makes an angle of 60o with the normal, find the direction of the reflected ray.

The position x of an experimental rocket moving along a long rail is measured to be x(t) = (4m/s)t + (7m/s2)t2 + (5m/s3)t3 – (0.35m/s4)t4 over the first 10s of its motion, where t is in seconds and x is in meters. Find the velocity of the rocket for the first 10 seconds

What is the power of an elevator which can lift a 100 kg mass a distance of 20 m in 5 seconds?

The phenomenon of damping results in decrease in

According to this law, “The force between two charges varies directly as the magnitude of each charge and inversely as the square of the distance between them

Which of the following is true? The density of water
