Solutions:
S1.Ans.(b)
Sol. Pascal’s Law states that pressure that is applied to an enclosed fluid is transmitted equally to all other points. A hydraulic pump is a water pump that uses the kinetic energy of flowing water to force a small fraction of that water to a reservoir at a higher level. The hydraulic lift works because of Pascal’s law. If force is put on(according to Pascal’s Law), that force should be entirely felt on all points throughout the liquid.
S2.Ans.(a)
Sol. At -40 degrees, the numerical values on Celsius and Fahrenheit scales become equal.
S3.Ans.(c)
Sol. Sublimation is the phase transition of a substance directly from the solid to the without passing through the intermediate liquid phase.
S4.Ans.(a)
Sol. When a ball is thrown vertically upwards, energy remains constant during its motion.
S5.Ans.(a)
Sol. Heat is the amount of energy that flows spontaneously from a warmer object to a cooler one. In SI system, heat energy is measured in joules (J).
S6.Ans.(d)
Sol. The Sun and the planets move around each other with their center of mass lying at the focus of the elliptical orbits. In other words, If the orbit of a planet is an ellipse then the point at which the Sun is located called Focus.
S7.Ans.(d)
Sol. The sliding friction is smaller than the static friction.
S8.Ans.(d)
Sol. The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI).
S9.Ans.(a)
Sol. Willem Einthoven invented the electrocardiogram (ECG).
S10.Ans.(d)
Sol. If the speed of an object moving along a straight line keeps changing with time then its motion is said to be non-uniform motion.
