Answer:

Displacement is a vector quantity

Explanation:

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

What is the difference between heat capacity and specific heat capacity? I want the meaning please.

charle [14.2K]

Answer:

The heat capacity of a body is defined as the heat required to raise it's temperature by me degree or one kelvin.while specific heat capacity of a substance is defined as the heat required to the temperature of a unit mass of it through one degree or one kelvin.

While it’s impossible to design a perpetual motion machine, that is, a machine that keeps moving forever, come up with ways to k

TEA [102]

It would be hard so many factors play a role in this angle kinetic potential energy gravity positioning height weight etc.to keep something as described moving as long as possible you'd have to build it heavily enough to balance out the momentum at each climax of the swing to balance with the gravitational pull of the earth core.I'd use a material such as copper for the variable.Also the weight distribution on the variables base plays a role.Take all the into account and experiment for a while!maybe one day you could find the right proportions in every role for kinetic potential gravitational momentum and weight to keep it going forever. As said alotta factors play a huge role in this experiment

An airplane in the earth’s magnetic field can develop a voltage between its wingtips.

Svetradugi [14.3K]

Answer:

$emf=0.125\ V$

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

Explanation:

Given:

velocity of plane, $v=250\ m.s^{-1}$

magnetic field, $B=5\times 10^{-5}\ T$

angle between velocity and magnetic field, $\theta=30^{\circ}$

span of the wing, $l=20\ m$

We know:

$emf=B.l.v\ sin\theta$

$emf=5\times 10^{-5}\times 20\times 250\times sin30^{\circ}$

$emf=0.125\ V$

According to the Fleming's Left left hand rule we have higher potential on the right edge of the wing.

How does charging by conduction work?

anzhelika [568]

Answer:

During charging by conduction, both objects acquire the same type of charge. If a negative object is used to charge a neutral object, then both objects become charged negatively. ... In this case, electrons are transferred from the neutral object to the positively charged rod and the sphere becomes charged positively.
