A 5kg object has a kinetic energy of 250J. Find the speed of the object by rearranging the formula :[tex]\sf{ KE=v^2\dfrac{m}{2}}[/tex]

Kinetic energy of an object is the energy possessed by the virtue of its motion.

Kinetic energy is given by:

[tex] \quad\hookrightarrow\quad{\pmb{ \sf {KE=\dfrac{mv^2}{2} }}}[/tex]

Here, we are given that:

By using the given formula:

[tex] \implies\quad \sf{ KE =\dfrac{mv^2}{2}}[/tex]

[tex] \implies\quad \sf{ 250 = \dfrac{5\times v^2}{2}}[/tex]

[tex] \implies\quad \sf{\dfrac{ 5}{2}\times v^2 = 250}[/tex]

The box moves to the left side due to application of more force.

The box moves to the left direction because double force is applied on it whereas small force is applied from the left side. If the same amount of force is applied from both sides then the box will not move but due to unequal force, the box will move in the direction in which more force is applied.

Cricket bat uses one common law of physics

When a ball hits the bat with some velocity ,the cricket bat should hit with some more velocity to get greater impact velocity to move the ball somewhere .

Answer:

Using the equation for orbital speed

orbital speed= square root of GM/r

Where

G= Gravitational Constant = 6.674x10^-11m^3/kg.s^2

M= mass of The Earth=5.972x10^24 kg

r= the combined radius of The Earth and the height of the satellite above The Earth=6378km+ 3600km= 9978km converting to meters gives (1000m=1km) 9978km*1000m/1km= 9,978,000m or 9.978x10^6m

orbital speed = square root of (6.674x10^-11*5.972x10^24/9.978x10^6= 63198m/s

It would be 3: a spring descending a set of steps. As kinetic energy is the energy of motion, it must be in motion.

Since it is moving, it would be a spring moving down a set of steps. A stretched spring, a compressed spring, and a spring at the top of a set of steps are all in motion.

Kinetic energy is a type of power that a moving object or particle possesses.

An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. A moving object or particle has kinetic energy, which depends on both its mass and its rate of motion.

Therefore, It would be 3: a spring descending a set of steps. As kinetic energy is the energy of motion, it must be in motion.

It can be deduced that the amount of conventional current that is flowing in the wire is 0.1608 A.

The conventional current simply means the charge per unit time that is transported in a certain direction.

In this case, the magnetic field B of the wire makes an angle θ with the earth's magnetic field BEarth. From the tangent law of magnetism,

B = BEarth × tanθ

= (2 × 10 - 5T) × tan15 = 5.36 × 10-6 T

The current flowing through the wire will be:

I = 2πrB / μ0

I = 2π × (6 × 10-3m)(5.36 × 10-6 T) / (4π × 10 - 7)

I = 0.1608 A

Therefore, the amount of conventional current that is flowing in the wire is 0.1608 A.

which of the following is a vector quantity?

Weight is the only quantity that is vector among the others. Power, density, volume all are scalar quantities.

Weight is a scalar quantity because it has a direction. Weight is the force applied by earth on an object. Now, the force must have a direction so it is a vector quantity!!~

Answer:

D) The weight of an elephant

Answer:

The leaves of an electroscope will return to their original position if the electroscope is not grounded because the final condition of the electroscope is the same as it was originally.

If however if one touches the terminal of an electroscope while the scope is exposed to a source of static electricity, and then the contact with the terminal is removed before the source of static electricity is taken away, then any excess electrons will remain on the electroscope and the leaves will remain diverged.

a = 0.227 m/s²

Answer:

NEGATIVE

Explanation:

It is Negative beacause POSITIVE and NEGATIVE attract. It's just like a magnet... I think you have tried that if you put the south pole of a magnet close to another south pole of another magnet, then it REPELS right? That's because they don't attract, but if you put south and north together, then they WILL attract to each other.

Same with Positive and Negative Electrons

If the ground is Positive, and the lightning gets attracted to the cloud, that means that the cloud is NEGATIVE

Glossary: (italic words)

Repel - going away from each other

attract - coming even closer to each other

Thanks!

Electrons that have accumulated in one spot and discharged themselves create lightning. A lightning strike has a very negative source.

A cloud-based electrical discharge known as lightning can be seen. When there is an imbalance in the charges between one area of the cloud and another surface, this occurs.

The earth has a positive charge compared to the cloud when lightning from the cloud strikes the earth.

Electrons from the cloud are released into the ground. The air becomes extremely hot and enters a highly conductive plasma state during the discharge.

Leaders might have also formed in other portions of the same cloud where there are electron-depleted patches with a positive charge.

The earth, which has recently had a significant influx of electrons and has become negatively charged, is channeled by the plasma from the original strike.

Thus, the cloud will be negatively charged.
