locity of the car = 54 km/hMass of the boy = 40 kgTo findKinetic ENERGY of the boySolutionFirstly, we will convert the velocity of the car from km/h to m/s.For converting it to m/s, multiply the VALUE by 5/18.⟼ 54 × 5/18⟼ 15 m/s❖ Velocity of the car = 15 m/sFormula to be used :-❖ KE = 1/2 mv²Where, m = mass of the boyv = velocity of the carSubstituting the given VALUES, ⟼ KE = 1/2 × 40 × (15)²⟼ KE = 20 × 15 × 15 ⟼ KE = 4500 J ❖ Kinetic energy of the boy = 4500 J

The EXACT solution for any physical model is of great importance in the applied science. Such exact solution leads to the CORRECT physical interpretation and it is also useful in validating the approximate analytical or numerical methods. The exact solution for the peristaltic transport of a Jeffrey FLUID with variable viscosity through a porous medium in an asymmetric channel has been achieved. The main advantage of such exact solution is the avoidance of any kind of restrictions on the viscosity parameter α, unlike the previous study in which the restriction α ≪ 1 has been put to achieve the requirements of the regular perturbation method. Hence, various plots have been introduced for the exact effects of the viscosity parameter, Daray’s number, porosity, amplitude ratio, Jeffrey fluid parameter, and the amplitudes of the waves on the pressure rise and the axial velocity. These exact effects have been discussed and further compared with those approximately obtained in the literature by USING the regular perturbation method. The comparisons reveal that REMARKABLE differences have been detected between the current exact results and those approximately obtained in the literature for the axial velocity profile and the pressure rise.

power of lens is KNOWN as the inverse of the focal length of the lens measured in METRE SI unit of power is equal to DIOPTRE of power of lens is equal to 1 / focal length in metre the focal length of FIRST lens F1 is equal to 40 centimetre is equal to 0.4 m the lens used is a convex lens because the focal length is a positive value.Explanation:give the power of the lens is + we then it is a convex lens if the power of a lens is -ve the it is CONCAVE lens a what is the value of f is given in cm we should convert it to metre.make me as brainlist.

sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid. In human physiology and PSYCHOLOGY, sound is the reception of such waves and their perception by the BRAIN.[1] Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the AUDIO frequency range, elicit an auditory percept in humans. In air at ATMOSPHERIC pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimetres (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges.

No LAKSHMI is WRONG as Carbon Monoxide or CO REPRESENTS compound not the element. But COBALT or co is an element

I don't KNOW the ANSWER

1:9Explanation:Initial velocity =v, then v =3v (TRIPLED Velocity)Initial KINETIC energy = 21 MV 2 FINAL kinetic energy (K.E.)= 21mv ′2 = 21 m(3v) 2=9( 21mv2 )∴ (K.E.) initial:(K.E.) ffina=21mv 2:9( 21mv 2)=1:9
