here's the ANSWEREXPLANATION:The acceleration of an OBJECT changes with altitude. The CHANGE in gravitational acceleration with distance from the CENTRE of Earth FOLLOWS an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.please mark as the brainliest answer

of Sines establishes a relationship between the angles and the SIDE lengths of ΔABC: a/sin(A) = b/sin(B) = c/sin(C). This is a MANIFESTATION of the fact that COSINE, unlike sine, CHANGES its sign in the range 0° - 180° of valid angles of a triangle.

Plane mirror and concave mirror provide ERECT and virtual image while concave mirror FORMS an INVERTED and real image.Hope it helps u....Please mark it the brainliest answer and FOLLOW me ☺️❣️

Subtracting a VECTOR is the same as adding its NEGATIVE. The DIFFERENCE of the vectors p and q is the sum of p and –q. Example: Subtract the vector v from the vector u

The eardrum is like a STRETCHED rubber sheet. SOUND vibrations make the eardrum vibrate. The eardrum SENDS vibrations to the INNER ear. From there, the signal goes to the brain.

i don't KNOW !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

i tried my best, hope it helps.Explanation:the definition of an electric field is F/Q, where q is in the field, and the definition of electric potential is ELECTRICAL potential energy divided by charge. E = F/q V = E/q W = FdSo by substitution, W = EQD I want to GET to E = V/d so I'll solve for E... E = W/qd So W/q is somehow equal to V? So W/q = E/q And by the work energy theorem, W = delta E, and the VOLTAGE in E = V/d is in fact a potential difference.

The MAXIMUM height of the object is the highest VERTICAL position along its TRAJECTORY. The maximum height of the projectile depends on the initial velocity V, the launch angle θ, and the acceleration due to GRAVITY. The unit of maximum height is meters (m).

(3) 240 W is the CORRECT ANSWER.

i am SORRY i DONT KNOW ANSWER

The electromagnetic spectrum covers electromagnetic waves with frequencies RANGING from below one hertz to above 1025 hertz, corresponding to WAVELENGTHS from thousands of kilometers down to a fraction of the size of an atomic NUCLEUS. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible LIGHT, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end.

hey FRND your answer is 2.5cmhope U GET your answer thnx for askingplzz MARK as brainlist.....

velocity is the speed with a DIRECTION, while speed does not have a direction. Speed is a scalar quantity—it is the MAGNITUDE of the velocity. Speed is measured in units of distance divided by time (e.g., miles per hour, feet per second, METERS per second, etc.).. I hope it will help u. PLZZ FOLLOW me freind

A DIPOLE moment is a measurement of the separation of two opposite ELECTRICAL charges. Dipole MOMENTS are a vector quantity. The magnitude is equal to the charge multiplied by the DISTANCE between the charges and the direction is from negative charge to positive charge: μ = q · r.

3. (i) When a carpet is beaten with a stick, the dust COMES out of it because of law of inertia. Initially the dust particles are at rest along with the carpet. Beating the carpet with the stick makes the carpet to move but the dust particles remain at rest due to inertia at rest, thus the dust gets detached from the carpet.(ii) v = 30 m/s     t = 10 s    When a car starts from the rest, its initial VELOCITY is 0 and here its moving velocity is mentioned to be 30 m/s.So the difference in these two velocities is 30 – 0 = 30 m/s.Hence, the ACCELERATION of the car is calculated as this difference in velocities / time, means here it is 30 / 10 = 3. The FORMULA for finding the force is acceleration x mass, i.e. 1500 x 3 = 4500 NHOPE THAT IT WAS HELPFUL!!!!MARK IT THE BRAINLIEST IF IT REALLY WAS!!!!

ter at 100°C and 1 atm pressure is heated to convert it to 1521 of vapour. The heat of vaporization of water =540 cal/g. Find the INCREASE in INTERNAL energy.Work done, W = Pressure * Change in Volume = Heat required, Q = Mass * Latent Heat of vaporisation = Increase in internal energy, ΔU = Q - W = 2103.3 J = 2.103 kJHence option (2) is CORRECT.

Hope it helps you .Explanation:donate. To donate means to give SOMETHING — money, goods, or time — to some cause, such as a charity. The word has a more altruistic meaning than does SIMPLY "GIVING"; it suggests that you don't EXPECT anything in return for the contribution.
