Answer:Newton's 2nd law

Explanation:Newton's 2nd law also states that the rate at which an object changes speed is proportional to the force that is exerted. Engines provide thrust and accelerate a plane forward along the runway. If the engines supply a small force, only a small acceleration will result.

Explanation:

Answer:

q = 0.384 C

Explanation:

The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:

[tex]q = ne[/tex]

where,

q = total charge on head = ?

n = total no. of electrons on the head = 2.4 x 10¹⁸

e = charge on 1 electron = 1.6 x 10⁻¹⁹ C

Therefore,

[tex]q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)[/tex]

q = 0.384 C

Natural fibers or natural fibres are fibers that are produced by plants, animals, and geological processes. They can be used as a component of composite materials, where the orientation of fibers impacts the properties. Natural fibers can also be matted into sheets to make paper or felt.

Answer:

(assuming gravity = 10m/s2)

answer for part 1 :

the pot will possess potential energy and not kinetic energy.

the energy which the pot possess is = PE of the pot

PE = mgh = 1.2x 10 x 30 = 360 J

answer for part 2 :

PE = mgh = 1.2 × 10 × 6 = 72 J

Explanation:

the PE of a body is not due to its state of motion, its due to the state of rest of the body. when the body starts moving it possess kinetic energy.

Answer:

The magnitude and direction of the force between the two charges is 497.66 N in opposite direction.

Explanation:

From the question given above, the following data were obtained:

Charge 1 (q₁) = 1.4×10¯³ C

Charge 2 (q₂) = 9.1×20¯⁴ C

Distance apart (r) = 4.8 m

Force (F) =?

NOTE: Electric constant (K) = 9×10⁹ Nm²/C²

The magnitude of the force between the two charges can be obtained as follow:

F = Kq₁q₂ / r²

F = 9×10⁹ × 1.4×10¯³ × 9.1×20¯⁴ / 4.8²

F = 11466 / 23.04

F = 497.66 N

Thus, the magnitude of the force is 497.66 N.

Since both charges has the same sign (i.e they both positive), the force between them will be a force of repulsion. Hence the force will be in opposite direction.

Answer:

C

Heavy nucleus split during fission and two light nuclei bind together during

fusion.

Answer:

A This is a nuclear reaction, because the atoms nucleus changed.

Answer:

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. A rocket engine produces thrust through action and reaction. The engine produces hot exhaust gases which flow out of the back of the engine. In reaction, a thrusting force is produced in the opposite reaction.

Answer:

Sound quality

Explanation:

Loudness refers to the property of sound that depends on the amplitude of the sound wave while pitch is the property of sound that depends on the frequency of the sound wave.

Now, when sounds have the same pitch and loudness, it means they possess the same natural frequency and also, they will have similar resonance and standing waves. Despite all these similarities, the quality of these sounds will tend to vary from one to another.

C) the sound quality

Explanation:

Hey you said this one would give 100 points.

Answer:

F = 2000 N

Explanation:

According to Newton's Second Law of Motion, the rate of change of momentum is equal to the force applied. Therefore, the formula written below will be used to solve this problem:

[tex]F = \frac{\Delta P}{t}\\\\[/tex]

where,

F = Force everted = ?

ΔP = Cange in Momentum = 3000 N.s

t = time taken = 1.5 s

Therefore,

[tex]F = \frac{3000\ N.s}{1.5\ s}[/tex]

F = 2000 N

Answer:

speed :m/s

velocity:m/s-¹

acceleration:m/s²

force:kgms-²

Explanation:

I hope May be correct

Speed: It is the rate at which object covers or travelled particular distance or rate at which objects changes its position. S.I. unit for speed is metre per second (m/s).

Speed (s) = distance (d) / time (t)

Velocity: Distance covered by a moving object in a particular direction per unit time. S.I. unit of velocity is m s-1 or m/s.

Velocity (v) = Total displacement (d) / time take(t)

Momentum: It is quanity of motion of the object. S.I. Unit is Kg.m.s-1

Momentum (p) = Mass (m) X Velocity (v)

Acceleration: Rate at which an object velocity changes with respect to time. S.I. unit is metres/second2 (m/s2) Acceleration (a) = Change in velocity/ time taken

Force: When an object changes it position or direction due to external agent. S.I. unit of force is (Kg m/s2).

Force (F) = Mass(m) × Acceleration (a)

Answer: tens of thousands of years ago.

Explanation:

The Sun makes energy by nuclear fusion which is a process by which hydrogen atoms are fused to form helium atoms.

It does this in the core and the process releases a lot of energy that takes quite a long time to get to the surface from said core.

Scientists say that the energy takes between 10,000 and 170,000 years for the energy to escape the core to the surface where it is then radiated to Earth as light.
