Hey mate here is your answer


PERSONAL Error :- An error CAUSED by an OBSERVER’s personal habits, mental or physical reactions, or INABILITY to perceive dimensional values exactly. It may be ACCIDENTAL or systematic. A systematic personal error is termed a “personal equation.”



Hope it will help you

According to NEWTON's third law of motion,every ACTION has an equal and opposite reaction.
So, when horse apply force on ground with it feet, ground apply equal force on horse feet.
But MUSCULAR force by horse body is more than that applied by ground,so horse MOVES.

Observational error (or MEASUREMENT error) is the difference between a measured value of a quantity and its TRUE value. In STATISTICS, an error is not a "mistake". Variability is an inherent PART of the results of measurementsand of the measurement PROCESS.

It is not necessary
you statement is valid for case I

It is in both REST n motion the thing that MAKES different is our point of refraction

ANSWER:
It is difficult to hold a school bag having a STRAP made of thin and strong string, because the thin string has very less contacting area in case of a school bag having a strap made of thin and strong string which increases pressure which is UN comfortable to carry the school bag.

Answer:

EXPLANATION:

SI unit of would joule,CGS unit is ERG.

1joule=10^7 erg

Is the ANSWER I THINK

Vertical velocity at TOP is 0, because while going upwards due to the ACCELERATION due to gravity, the velocity decreased, and at Max HEIGHT the vertical velocity is equal to ZERO.

When an OBJECT MOVES in a STRAIGHT line without changing in its DIRECTION

Circular MOTION:
Moving of an object in the circular path is called circular motion.
It can be either uniform or non uniform.

Few examples:
* Rotation of Earth AROUND the sun.
* Movement of the fan blades when it is in motion.
* Spinning TOP.
* Running around the circular path in the athletics.

The BALL will FALL backwards CAUZ the train and U r in motion and not the ball.........
Was it helpful for u????

Then the OBJECT will be VIRTUAL and ERRECT
THANK U

In first 2 MINUTES it returns to its initial position as it completes 3 revolutions. in last 20 SECONDS it completes half of the CIRCLE . HENCE displacement is 2 times the radius of the circle as it is shortest possible path .

Fossil fuels are used in automobile , used in production of electricity.
on combustion of fossil fuels lots of pollutants are PRODUCED which is very. HARMFUL for our HEALTH and ENVIRONMENT

If the object moves ALONG a STRAIGHT PATH in the same direction as started in the beginning.

Hope helps

Force = Mass x ACCELERATION
acceleration is the CHANGE in velocity
mass = 2.5 KG. Acceleration = 10m/s ^2
force =

1)Energy DEMAND in rural areas is on a steady rise. India is the fourth largest energy consumer in the world. The present energy use is mostly in the areas of domestic cooking and lighting, agriculture, transport and industrial sectors. India’s energy BASKET has a mix of all the resources available including renewables.

2) The largest energy source is coal, followed by petroleum and TRADITIONAL biomass. According to the 2011 Census, the household-level data INDICATES that only 55.3 per cent of rural homes used electricity as the primary source for lighting.

3)Energy access, with about one fourth of the population lacking access to electricity and energy security, with the country relying on imports for a considerable amount of its energy use, particularly for crude petroleum are key challenges that the country faces with respect to energy. WIDE disparity in energy use pattern between the haves and have-nots, urban and rural and men and women are also a cause of concern.

Have you heard if formula:

VOLTAGE (V) = WORK done(w)/ charge (q)

1 VOLT means , 1 Joule of work is done in MOVING a 1 Coulomb charge between that two points

Inertial frame of reference is frame of reference in which Newton's first law remains true.

Lets say someone is driving a car and you are the passenger. From your point of view in the vehicle, you and the driver of the car are SITTING STILL. However, to a bystander standing still outside the vehicle, you and the driver appear to be moving. We can call these two points of view two different frames of reference. In physics, we classify frames of reference by two main types: inertial and non-inertial.

Inertia is the property of matter in which an OBJECT that is at rest wants to remain at rest, and an object that is moving wants to remain moving in a straight line unless another force acts upon it. Likewise, an inertial frame of reference is a reference frame in which an object stays either at rest or at a constant velocity unless another force acts upon it.

When a body does not seem to be acting in accordance with inertia, it is in a non-inertial frame of reference. In other words, a non-inertial reference frame is a frame of reference that is undergoing acceleration with respect to an inertial frame.

Let's continue with the earlier example. Let's IMAGINE the car with you and the driver is a limousine and the road is very smooth so you have no way of KNOWING if the car is moving or stationary. In fact, to you, all that matters is that you both are sitting in the car. The bystander outside the vehicle will always be in an inertial frame of reference since he or she is standing still, i.e., at rest. For you, it depends on the vehicle's movement. Let's assume the vehicle is moving in a straight line. If the vehicle is not accelerating, then you and the driver are also in an inertial frame of reference. This is because no acceleration means your velocity is constant. If the vehicle begins accelerating, you and the driver are now in a non-inertial frame of reference.

Hope it helps!

3/2t^2-4/3t^3. I THINK this is the ANSWER

A MICROSCOPE, LIKE a reflecting telescope, uses a concave mirror, a plane mirror, and a convex LENS. However, they are used to magnify very small IMAGES on slides not in the sky.

Under
HIGH WIND SPEED

Ohm's LAW states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance,[1] one arrives at the usual mathematical equation that describes this relationship:[2]

{\displaystyle I={\frac {V}{R}},}

where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.[3]

The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical CIRCUITS containing various lengths of wire. Ohm EXPLAINED his experimental results by a slightly more complex equation than the modern form above (see History).

In physics, the term Ohm's law is also used to refer to various generalizations of the law originally formulated by Ohm. The simplest example of this is:

{\displaystyle \mathbf {J} =\sigma \mathbf {E} ,}

where J is the current density at a given location in a resistive material, E is the electric field at that location, and σ (sigma) is a material-dependent parameter called the conductivity. This reformulation of Ohm's law is DUE to Gustav Kirchhoff.[4]

Volume of SOLUTE =150ML

Volume of solvent=600ml

Volume of solution=Volume of solute+Volume of solvent

=150+600

=750ml

CONCENTRATION of a solution=Volume of solute*100/Volume of solution

= 150*100/750

=20 %

Hi there!

The DISADVANTAGES of HYDROELECTRIC energy are as follows:

1. ENVIRONMENTAL Consequences

2. Expensive.

3. Droughts.

4. Limited resources.

Hope it helps U!!

Natural geysers are somewhat like springs of HOT water. they provide THERMAL energy used for the generation of electricity. they are found in places where the geotherma energy Is more. Yellowstone NATIONAL park in USA is a famous example.




hop a ur helps U...

The key for solving every problem in physics is the converison of units to SI units.

Lets go from the last part of the question. The DISTANCE is given and the time is required. The relation among these two is d=v*t. For finding the time we need to find the velocity and distance (distance is already known), so our main target is to find velocity of wave in this case. 
For finding the velocity of wave when frequency and wave length is given, you ca use the relation v= (wavelength(in METER)* frequency) .It will give you the RESULT of 0.8 m/s.

So the time taken will be

v=d/t where d must be in metres and time in seconds.

on solving, you will get the answer......

The water n ICE particles in the cloud we see are simply too SMALL to feel the effect of gravity n velocity as a result they APPER to float on air
it's lk tiny dust particles in air against the shaft of sunlight
Indeed the distance from the center of a typical water droplet to its edge its radius n ranges from few tens of microns and the speed with which an object falls is related to its mass n surface area which is why it doesn't effect the particles in cloud
So even though typical clouds do CONTAIN tons of water, this water is spread out for miles for miles in form of tiny droplets or crystals n they are in negligent weigh

Hope this HELPS

Velocity = 0 at highest POINT
