I THINK C is RIGHT.....

So it means energy is something which can itself do work or allow us to do work.Heat,which is a FORM of energy can do thermal work.Sound can make THINGS VIBRATE.... Other energies as chemical energy have hidden effects.

Sonar is the name of instrument used to see and examine the object that are PRESENT under water.  

Sonar is solely creating use of an echo. As an animal or machine makes a noise, it transmits the sound waves into the setting around it. Those waves bounce off near objects, and a few of them mirror back to the item that CREATED the noise.

Sonar is employed to seek out objects on very cheap of the ocean. facet scan navigational instrument is one technique WONT to CONSIDER the detail of the seabed. facet scan navigational instrument instruments area unit towed behind ships and sometimes referred to as towfish or tow vehicles (shown below).

Sonar (originally an form for Sound Navigation And Ranging) could be a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or observe objects on or beneath the surface of the water, LIKE different vessels.

C is correct EG : adrenaline released in EMERGENCY situations.Flight and fight HORMONE

The reaction in which HEAT is RELEASED from the system called exothermic and heat is PROVIDED/ ABSORBED by the system is called endothermic reaction

Let V be the VOLUME of the iron body and ν be its volume IMMERSED in mercury.
For floatation Weight of the body = Weight of the LIQUID displaced by the immersed portion of the body.
i.e., V × 7.8 × g = ν × 13.6 × g
or ν/V = 7.8/13.6
= 0.574
or ν = 0.574 V
The FRACTION 0.574 of total volume will remain immersed.

Torque and angular momentum are perpendicular to the direction of force/momentum by convention. In other words, it is a pragmatic but otherwise arbitrary decision.

Part of what we are trying to indicate with a cross product vector for torque or angular momentum is the direction of rotation — e.g. whether it is clockwise or counter-clockwise — but the direction of rotation is only meaningful RELATIVE to the plane the object is rotating in. Think about a bicycle wheel. If the wheel is rotating clockwise from our perspective, and we then spin the handlebars 180°, the wheel is suddenly rotating counter-clockwise from our perspective. The wheel hasn’t changed its direction of rotation in any meaningful sense, obviously, but the plane of its rotation has shifted 180°. In FACT, the only consistent perspective on the direction of rotation of a wheel is from the perspective of its axle:

No MATTER which way we turn the wheel, it will still be SPINNING in the same direction with respect to its axle. And so we make the right-hand-rule convention: we use one vector if the wheel is spinning one way with respect to the axle (counter-clockwise means thumb pointing up, or at us), and the opposite vector if the wheel is spinning the other way (clockwise means thumb pointing down, or away from us).


torque is represented by the large yellow arrow, and angular momentum by the smaller purple arrow. Note that they are out of phase by one-quarter cycle because torque is maximum as the swinging arm accelerates while angular momentum is maximum when acceleration ceases and the arm begins to slow.

This conventional vector tells us three meaningful and useful things:

It has a magnitude that gives the size of the effect: the magnitude of angular momentum/torqueIt has an orientation vector that is orthogonal (perpendicular) to the plane the object is rotating in, and thus defines the plane absolutelyIt has a positive/negative (up/down) value that indicates the direction of rotation with respect to that plane.

So, by CONSTRUCTING torque/angular momentum as a vector perpendicular to the plane of rotation, we are able to fully describe the rotation of the object: the magnitude of rotation, the plane it is rotating on, and the direction of rotation within that plane

HELLO mate.

Thanks for asking this question.

Your answer is =

The average velocity of the train is the total velocity times the RELATIVE time period per total time taken.



So we calculate the average velocity of the train by following relation =>

Average velocity = SUMMATION of {velocity×time} ÷ total time

Average velocity = { 60×4 + 80×2 } ÷ { 4+2}

Average velocity = 400 ÷ 6 = 66.67 km/hr

Average velocity of the train is 66.67 Km/hr.

Yes…it’s ACCORDING to ARCHIMEDES principle which states that if a body is partially or fully immersed in a fluid then upward force (Buoyant force) acting on the body is equal to weight of the fluid DISPLACED.

hence,

Mass of displaced WATER =(volume of displaced water )x (DENSITY of water)

And immersed body will displace volume of water equivalent to its own volume.

So volume of water = volumeof object

Hence Mass of water = volume of object x density of water

A pendulum is a weight SUSPENDED from a PIVOT so that it can swing FREELY. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it BACK TOWARD the equilibrium position.

As PRESSURE = Force/ Area
pressure =ma/A= Vp/A= Ahpg/A = pgh
where A is uniform cross-section, H the DEPTH below the liquid surface, p the DENSITY of liquid

ANSWER:

The reason is why you GET out of the pool your body sweat a lot than before, which results in loss of vapour. Since evaporation is an ENDOTHERMIC PROCESS it will take out the HEAT from your body resulting you to feel cold

Newton’s LAWS of motion, relations between the forces acting on a body and the motion of the body, first formulated by English physicist and mathematician Sir Isaac Newton.


Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. This postulate is known as the law of inertia. The law of inertia was first formulated by Galileo Galilei for horizontal motion on Earth and was later generalized by René Descartes. Before Galileo it had been thought that all horizontal motion required a direct cause, but Galileo deduced from his experiments that a body in motion would remain in motion unless a force (such as friction) caused it to come to rest.



basketball; Newton's laws of motionWhen a basketball player shoots a jump shot, the ball always follows an arcing path. The ball follows this path because its motion obeys Sir Isaac Newton's laws of motion.
wtNewton’s second law is a quantitative description of the changes that a force can produce on the motion of a body. It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. The momentum of a body is equal to the product of its mass and its velocity. Momentum, like velocity, is a VECTOR quantity, having both magnitude and direction. A force applied to a body can change the magnitude of the momentum, or its direction, or both. Newton’s second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation.

Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. This law is important in analyzing problems of static equilibrium, where all forces are balanced, but it also applies to bodies in uniform or accelerated motion. The forces it describes are REAL ones, not mere bookkeeping devices. For example, a book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book. This force occurs because the weight of the book causes the table to deform slightly so that it pushes back on the book like a coiled spring.

Newton’s laws first appeared in his masterpiece, Philosophiae Naturalis Principia Mathematica (1687), commonly known as the Principia. In 1543 Nicolaus Copernicus suggested that the Sun, rather than Earth, might be at the centre of the universe. In the intervening years Galileo, JOHANNES KEPLER, and Descartes laid the foundations of a new science that would both replace the Aristotelian worldview, inherited from the ancient Greeks, and explain the workings of a heliocentric universe. In the Principia Newton created that new science. He developed his three laws in order to explain why the orbits of the planets are ellipses rather than circles, at which he succeeded, but it turned out that he explained much more.
