-The SPEED of light in vacuum is unity.To FiNd :-The distance between the Sun and the EARTH.SoLuTiOn :-We know,Distance = speed × timeSpeed in unity = 1 unit /secTime = 8 min and 20 SECS   = (8 × 60) + 20 sec = 500 secsSubstituting the values :-Distance between Sun and Earth = 1 × 500 = 500 units

A cyclotron is a type of compact PARTICLE accelerator which PRODUCES radioactive isotopes that can be used for imaging procedures. Stable, non-radioactive isotopes are put into the cyclotron which accelerates charged PARTICLES (protons) to high ENERGY in a magnetic field.

↗ For first case :▪ Initial VELOCITY = zero (i.e. rest)▪ Final velocity after = 6mps▪ Time interval = 30s↗ For second case :▪ Initial velocity = 6mps▪ Final velocity = 4mps▪ Time interval = 5sTo Find :▪ Acceleration of BICYCLE in both the cases.Concept :✏ Acceleration is defined as the RATE of change in velocity. (wrt time)✏ It is a vector quantity.✏ It can be positive/negative/zero.✏ It has both magnitude as well as direction.✏ SI unit : m/s²Calculation :↗ First case :↗ Second case :[Note : Negative SIGN shows retardation.]

Explanation:This constant of PROPORTIONALITY is KNOWN as resistivity or SPECIFIC RESISTANCE

1. ANGLE of Incidence equal to angle of reflection. 2.Angle of incidence,angle of reflection and normal all LIES on a same plane.Explanation:I HOPE this answer helps you. Please GIVE me a thanks.

Reflection is the CHANGE in DIRECTION of a wavefront at an interface between two different media so that the wavefront returns into the MEDIUM from which it originated. Common EXAMPLES include the reflection of light, SOUND and water waves.Hope it helps

For a convex mirror focal LENGTH is always POSITIVE. Because image forms always at the right side. So, F =10.8 cmU = -32.7 cm ACCORDING to mirror FORMULA, 1/f =1/v +1/uSo, 1/10.8 + 1/32.7 =1/vSolving this we get v = 8.11 cm

There is a formula v = n⋋Explanation: v = n⋋Here, v is VELOCITY of the light n is FREQUENCY ⋋ is wavelength.I hope this will helps you please MARK as brainliest answer and also like my answer plz.

A water drop is composed of water MOLECULES that like to STICK together-an example of the property of COHESION. In the picture of PINE needles above, the water droplets are stuck to the end of the pine needles-an example of the property of adhesion.

IS UR ANSWER ❤️Relative density can be calculated directly by MEASURING the density of a sample and dividing it by the (known) density of the REFERENCE SUBSTANCE. The density of the sample is simply its mass divided by its volume._________❤️_________→FOLLOW ME→MAKE MY ANSWER BRAINLIST→GIVE THANKS TO MY ANSWER→BE HAPPY ALWAYS__________❤️________

the CHARGE on a single proton is 1.6 x 10^-16 Coulomb, and there are 6.02 x 10^23 ELECTRONS per mole, so the charge will be (1.6 x 10^-16) x (6.02 x 10^23) = 9.65 × 10⁴ C which is EQUAL to 1 Faraday.hope it helps¡¡

Distance between OBJECT and the MIRROR= 40 cm EXPLANATION:The image forms BEHIND the mirror at the same distance as the object and the mirror.

a) because gas is very abundant in atmosphere so it fills completely in a vessel.b)gas exerts pressure on the walls of the container DUE to KINETIC theory of gases, itexerts pressure on the walls of the container.c) WOODEN table, molecules are tightly packed as we compared to liquid and gasd) because gas are very much loosely packed as we know that compressibility is inversely proportional to packing of moleculesplease mark as BRAINLIEST ANSWER

It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths. How Do Black Holes Form? Scientists think the smallest black holes formed when the universe BEGAN. Stellar black holes are made when the CENTER of a very big star falls in upon itself, or collapsesExplanation:pls mark this as brainliest AND pls FOLLOW me

Filament TYPE electric BULBS are not power efficien because most of the electric power consumed by the filament of a bulb appears as heat and only a SMALL AMOUNT of electric power is converted into light.#gundi..✌✌

-STEP explanation: Speed= Distance/TimeSpeed= 500/10 km/hrSpeed= 50 km/hrHope it HELPS you and please mark as BRAINLIEST.

0.01 m/s Explanation:SPEED = distance / time distance = circumference = 2¶r = 2 X 0.105 x ¶        (10.5 cm = 0.105 m)                          = 0.66 m speed = 0.66/ 60           = 0.01m/s

In the case of a THICK plane mirror, reflection TAKES place at the two surfaces, (top and BOTTOM surfaces) and images are formed due to both. The second surface is silvered and therefore the second IMAGE is the brightest.so your answer in option (b)hope it helps¡¡

Object A is moving faster as it is COVERING more distance in less period of time.Please mark as Brainliest and HOPE it HELPS you.

a) because the mirrors are on the ceiling so that’s one image ! A room has 4 WALLS so that’s another 4 images! So 4+1= 5 so that is your ANSWER

vbbhg the BEST friend and I will be in the best WAY is fine but 10 tarik the fees and CHARGES for you to the correct INFORMATION for the first

The VELOCITY which force gives to MASS = 2612.2 m/s.Given :Force on the mass, F=128\ N.Mass, 490\ g =0.49\ kg.Time period in for which the force is applied, t=10\ s.According to the NEWTON's second law of motion, the force on an object is equal to the mass times times the net acceleration produced in the object, if a is the acceleration of the mass,F=ma\\\Rightarrow a = \dfrac Fm = \dfrac {128}{0.49}=261.22\ m/s^2.Let the mass be starts from rest, so that its initial velocity is u=0\ m/s and its final velocity which the force give be v.Using the equation of Kinematics,v=u+at\\v=0+261.22\times 10=2612.2\ m/s.Explanation:please add me to BRAINLIEST and follow me ✌️✌️❤️
