i don't KNOW BRO about your question

ong>ANSWER:

SORRY idk idk good MORNING have a NICE day ahead good morning

parabola

Explanation:

because

SPEED of car will not CONSTANT

ong>ANSWER:

CONDUCTANCE is EXPRESSED in TERMS of mho.

net FORCE ACTING = 5N - 3N

                          = 2N

HINT -The law of conservation of Angular Momentum STATES that "When the net external torque acting on a system about a given axis is zero, the total angular momentum of the system about that axis remains CONSTANT." ... The external torque on a body is zero, if the angular momentum of the body is conserved.

ong>Answer:

The energy possessed by an OBJECT due to its motion is CALLED KINETIC energ of that object.

Where m is MASS of the object and V is velocity of the object.

ong>Answer:

Calcium is the element with 'atomic NUMBER' 20. Explanation: Calcium belongs to group 2, period 4, and BLOCK 's' in the PERIODIC table. This is because calcium is an 'alkaline earth metal' and alkaline earth metals are placed in group 2 in the periodic table.

u = 0 m/s

v = 20 m/s

t = 5s

a = v-u/t

  = 20m/s - 0m/s / 5s

  = 4 m/s²

2as = v² - u²

2[4m/s²] = 400 m²/s² - 0 m²/s²

[8 m/s²]s = 400 m²/s²

s = 400 m²/s² / 8 m/s²

s = 50 m

∴ the DISTANCE traveled during this time is 50 m

Rubber is a polymer CHAIN which breaks on heating leading to DECREASE in INTERMOLECULAR distance. Hence, it contracts. Water at ordinary temperatures contracts and increases in DENSITY as it is cooled.

ong>Answer:

We choose +X east and +y north and measure all angles in the “standard” way  (positive ones counterclockwise from +x, negative ones clockwise). Thus, VECTOR d1 has magnitude d1=3.66 (with the unit meter and three SIGNIFICANT figures assumed) and direction θ1=900 also. d2 has magnitude d2=1.83 and direction θ2=−450 and vector  d3 has magnitude d3=0.91 and the direction θ3=−1350 we ADD the x and y COMPONENTS respectively.

x:d1cosθ1+d2cosθ2+d3cosθ3=0.65m

y:d1sinθ1+d2sinθ2+d3sinθ3=1.7m

(a) The magnitude of the direct displacement (the vector sum d1+

Explanation:

hope it help uh freind Mark me brainliest

we KNOW that, F=m×a

given that,

f=12n

m=4kg

t=3s.

therefore u=0

a=v-u/t=F/m

12/4=3m/s2

v=u+at

v=0+3×3=9m/s

kE=1/2mv2

ke=1/2×4×(9)2

K.E=2×81=162j.

hope it helpful for u

STRAIGHT LINE parallel to X AXIS

3457 EXPLANATION:because it is the MAXIMUM METER of a BULLET

object is always placed in front of the MIRROR hence the sign of object is taken as negative. SINCE, the CENTRE of curvature and focus lies behind the convex mirror, so sign of radius of curvature and focal LENGTH are taken as + (positive) in the CASE of convex mirror.

to FIND the DIRECTION of MAGNETIC FIELD

cal length =10cm so it's CENTRE of curvature =20cnobject id placed at 25 cm away from mirror therefore object is placed beyond CENTER of curvatureobject will be FORMED between f2 and C2 ,the IMAGE will be real,INVERTED, diminished

It is called neutralization reaction. Acid and base reacts and FORM SALT and water. EXAMPLE : SODIUM hydroxide and HYDROCHLORIC acid reacts to form sodium chloride and water

mps are MACHINES that can pump heat in both directions—from the inside to the OUTSIDE (COOLING) and from the outside to the inside (HEATING). Air conditioners, heat PUMPS, and refrigerators all use a similar process to transfer heat energy.

For this form of the equation, R has units J / ºK·mol  n has units mol  and T is in ºK, so NRT has units J (energy).   p is pressure in Pa, or N/m²  V is in m³, so pV = N·m = J (energy)   QED   If, INSTEAD, you use pressure in ATMOSPHERES (atm) and volume in liters (L),  then R has units L·atm / ºK·mol  and the RHS is in L·atm.  The RHS is in atm·L

tion:Unpredictable kind of MOTION where an object moves in any direction and the direction keeps changing CONTINUOUSLY is CALLED as Random motion.Ex- Moving of an AntMotion of football.Mark as BRAINLIEST FOLLOW

Newton's laws of motion are three physical laws that, together, laid the FOUNDATION for classical MECHANICS. They DESCRIBE the relationship between a BODY and the forces acting upon it, and its motion in RESPONSE to those forces.

distance=20+40=60m.displacement= -20M.

It may LEAD to shock.Explanation: Thermoplastics are GOOD CONDUCTOR of heat. When these are heated they LOST their shape and may lead to ELECTRIC shock.

pls mark as brainliestIn optics, a dispersive prism is an optical prism, usually having the shape of a geometrical triangular prism, used as a spectroscopic component. Spectral dispersion is the best known property of optical prisms, although not the most frequent purpose of using optical prisms in practice. Triangular prisms are used to disperse light, that is, to break light up into its spectral components (the colors of the rainbow). Different wavelengths (colors) of light will be deflected by the prism at different ANGLES, producing a spectrum on a detector (or seen through an eyepiece). This is a result of the prism's MATERIAL (often, but not ALWAYS, a glass) index of refraction varying with wavelength. By application of Snell's law, one can see that as the wavelength changes, and the REFRACTIVE index changes, the deflection angle of a light beam will change, separating the colors (wavelength components) of the light spatially. Generally, longer wavelengths (red) thereby undergo a smaller deviation than shorter wavelengths (blue) where the refractive index is larger.A good mathematical description of single-prism dispersion is given by Born and Wolf.[1] The case of multiple-prism dispersion is treated by Duarte.[2]The dispersion of white light into colors by a prism led Sir Isaac Newton to conclude that white light CONSISTED of a mixture of different colors.

15120 calExplanation:H=P×t/4.2cal=210×5×60×24/100(4.2)=15120 CAL

Explanation:GIVEN:---M1 = Mass of the Sun = 2 × 10^30 kg M2 = Mass of the Earth = 6 × 10^24 kg R = Average distance between the Earth and the Sun = 1.5 × 10^11 m G = 6.7 × 10^−11 Nm^2 kg^−2According to the UNIVERSAL law of gravitational , F = G× M1 × M2/ r^2(Put the values of all quantities, we get) =6.7×10^−11×2×10^30×6×10^24/(1.5×10^11)^2= 3.57 × 10^22 NHence, the FORCE of GRAVITATION between the Earth and the Sun is 3.57 × 10^22 N
