Answer:

In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom.

Based on the forces acting on the axes, the resultant moments will be (345, 400, 600 N·m)

= F₃ x 3

= -115 x 3

= -345 N·m

= F₁ x 2

= -200 x 2

= -400 N·m

= F₄ x 2

= -300 x 2

= - 600 N·m

In conclusion, the resultant moment about x, y, and z axes is (345, 400, 600 N·m)

The correct answer is 8.4 J⋅kg−1⋅K−1

Explanation :

We know that

Qi = Qf  

Therefore ,m1c1 ΔT = m2c2ΔT

Where m1 is 25g and m2 is 200g

so , 25c1 = (200+10)(22-2)

      25c1 = 420

Therefore , c1 = 210/25

c1 = 16.8J⋅kg−1⋅K−1

Hence the specific heat of metal is 16.8 J⋅kg−1⋅K−1

'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site.

The law of reflection specifies that upon reflection from a downy surface, the slope of the reflected ray is similar to the slope of the incident ray.

The reflected ray is consistently in the plane determined by the incident ray and perpendicular to the surface at the point of reference of the incident ray.

When the light rays descend on the smooth surface, the angle of reflection is similar to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in a similar plane.

Hence 'The normal is a line perpendicular to the surface of the mirror'.This is the correct statement that corrects an error on the site

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.

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.

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]

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

[tex] \implies\quad \sf{v^2 =\cancel{ \dfrac{500}{5}} }[/tex]

[tex] \implies\quad \sf{v^2 = 100 }[/tex]

[tex] \implies\quad \sf{ v =\sqrt{100}}[/tex]

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.
