Some physical quantities are more fundamental than OTHERS. In PHYSICS, there are seven fundamental physical quantities that are MEASURED in BASE or physical fundamental units: length, mass, time, ELECTRIC current temperature, amount of substance, and luminous intensity.

tion:no. a BODY cannot have uniform velocity with NON uniform velocity with non uniform rather it can have uniform speed with non uniform velocity actually velocity is DEFINED as change in displacement by time taken but it's a vector quantity and hence it also includes the DIRECTION where is speed is a scalar quantity which is defined similar to velocity in in as change in distance by air time taken for simplicity we can say that speed is the magnitude of velocity

Velocity-time graph is a straight line making an angle with the time-axis. The conclusions are: (i) The BODY is at REST when the displacement-time graph is parallel to the time axis. (ii) The body has UNIFORM acceleration when the velocity-time gaph is slightly INCLINED with the time axis.

The water rises, cools, and condenses. A cloud is formed! Clouds form when warm wet AIR rises and condenses in cold air. ... The second reason that clouds can FLOAT in the air is that there is a constant FLOW of warm air rising to meet the cloud: the warm air PUSHES up on the cloud and keeps it afloat. please mark me as Branillist ANSWERTHANKS for My answer ❤️❤️❤️ please please

In a series circuit, the current is the same at each resistor. ... The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. A voltage source is any pair of points between which an electrical potential difference exists.This potential difference can be constant, varying slowly or in a periodic cycle. It can be huge or really tiny.A somewhat constant voltage source is often called a ‘direct current’ (DC) voltage source. Generally, if one terminal is always higher in potential than the other, then it is a DC voltage source.If the voltage (difference in potentials) keeps REVERSING a particular number of times per second, then it is an Alternating Crrent (AC). The number of times per second here is called frequency and is measured in a very simple unit called Hertz. Typically, the frequency of power supply is 50 Hz (in Europe, India etc.) and 60 Hz in (USA etc.).Voltage SOURCES can be power supply terminals on a wall outlet or a phone charger or an electric train overhead power line. They can also be very tiny signal sources from small sensors, in which case, we use those signal as information, but not power.In deeper Electrical Engineering, the meaning of voltage source may be in contrast with another kind of electrical source known as Current Source. The difference is that, regardless of the load , in Voltage source, the available voltage is somewhat constant all the time whereas in current source, the available current is constant all the time.Now, a battery is an arrangement to make a power supply voltage source available. It is most often made of a chemical system where electrical energy is stored as ion imbalance within some chemical solutions that can be consumed as and when required. The ‘cells’ which together constitute a battery have specific voltage values particular to the nature of their chemistry. (EG. Lead Acid batteries have a cell voltage of 2Volts). Combining many cells in series or parallel, a battery is constructed to the required higher voltages and power ratings.Explanation:Hope it HELPS you

very HIGH esistivity is the CORRECT ANSWER

basically numericals are "physics problems". LIKE how we have "math problems" we have problems to SOLVE in physics too! ... They say math is the ROOT of physics. Theories are easy to understand but when you GET numericals...well, that's when things get a little painful In the begging.Explanation:welcome

The continuity equation is defined as the product of cross-sectional area of the pipe and the VELOCITY of the fluid at any given point ALONG the pipe is CONSTANT. ...Related Article: ...Δx1 = v1Δt. ...V = A1 Δx1 = A1 v1 Δt. ...Δm1= Density × Volume.=> Δm1 = ρ1A1v1Δt ——–(Equation 1)

The solid apparently weighs less in water when compared to AIR because of the upward buoyant force acting on it when it is SUBMERGED in water. According to Archimedes principle, the buoyant force acting on an object is equal to the WEIGHT of the fluid displaced by it. THEREFORE, the apparent decrease in the weight of an object is equal to the weight of the fluid displaced by it.Weight of displaced water = Apparent decrease in weight = 120−105=15 gfMass of displaced water = 15gVolume of solid = volume of water displaced = densitymass = 1g/cm 3 15g =15cm 3 Actual weight of solid = weight of solid in air =120gf (since buoyant force due to air is negligible)Mass of solid = 120gDensity of solid = VolumeMass = 15120 =8g/cm 3 Relative density of solid = Density water Density ssolid = 1g/cm 3 8g/cm 3 =8

The four fundamental UNITS we will use in this text are the meter (for length), the kilogram (for mass), the second (for time), and the ampere (for ELECTRIC current). These units are part of the metric system, which USES POWERS of 10 to relate quantities over the VAST ranges encountered in nature.

Image DISTANCE(v) = 14.5 cmHeight(hi) = 1.47 cmExplanation:GIVEN that, an object placed 54 cm from a convex mirror having the FOCAL length of 20.0 cm and height of image is 5.5 cm. We have to find the image distance (v) from the mirror and height of the image (hi). Form above data we have, focal length (f) of concave mirror is 20 cm, object distance (u) is -54 cm and height of image (hi) is 5.5 cm. Now, Using Mirror Formula: 1/f = 1/v + 1/u Where f is focal length, v is image distance from the mirror and u is object distance from the mirror (concave). Substitute the known values in the above formula to find the value of 'v' i.e. image distance from the mirror. 1/20 = 1/v + 1/(-54) 1/20 = 1/v - 1/54 1/20 + 1/54 = 1/v 0.069= 1/v v= 14.49 Therefore, the image distance from the convex mirror is 14.5 cm. Now, m = -v/u = hi/ho Substitute the values, -(14.5)/(-54) = hi/5.5 0.268 = hi/5.5 1.47 = hi Therefore, the height of the image is 1.47 cm.
