Answer:

Force = 143.16 Newton

Explanation:

Given the following data;

Distance, S = 22 m

Initial velocity, U = 10 m/s

Final velocity, V = 25 m/s

Mass = 12 kg

To find the force acting on the box;

First of all, we would determine the acceleration of the box using the third equation of motion;

V² = U² + 2aS

25² = 10² + 2*a*22

625 = 100 + 44a

625 - 100 = 44a

525 = 44a

Acceleration, a = 525/44

Acceleration, a = 11.93 m/s²

Next, we find the force;

Force = mass * acceleration

Force = 12 * 11.93

Force = 143.16 Newton

Explanation:

let the length be Lcm

5−325−L = 10−530−25

L = 23cm

Answer:

A

Explanation:

this because

gravitational potential energy = mass x height x gravitational field strength

so let's assume mass is 2 kg and gravitational field strength is 10 N /kg

so when height is very low, take it as 3 m

gravitational potential energy= 2 x 3 x 10 = 60 j

but when height is 6m

gravitational potential energy = 2 x 6 x 10 = 120 j

so when the height is the greatest, the gravitational potential energy is the highest

so A is the heighest so it has the highest gravitational potential energy.

hope this helps

Answer:

The Answer to question 14 is : glycerol (n=1.47)

The material should be considered as the glycerol (n=1.47).

Since

a beam of monochromatic light (f=5.09 × 10^14 Hz) has a speed of 2.04× 10^8 meters per second.

Now the material should be

= 3*10^8 / 2.04× 10^8

= 1.47

Hence, The material should be considered as the glycerol (n=1.47).

Abiotic variables are particularly essential since they have a direct impact on organisms' ability to live.

Answer:

They are totally different.

Explanation:

However, sound and radio waves are completely different phenomena. Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum. Conversely, radio waves are electromagnetic waves, like visible light, infrared, ultraviolet, X-rays, and gamma rays

Answer:

[tex]\boxed {\boxed {\sf A. \ 36 \ m}}[/tex]

Explanation:

The distance an object travels is the product of its speed and time.

[tex]d=s \times t[/tex]

The object's speed is 12 meters per second and the time is 3 seconds.

Substitute the values into the formula.

[tex]d= 12 \ m/s \times 3 \ s[/tex]

Multiply. Note that the units of seconds will cancel, so we are left with meters as our units.

[tex]d= 12 \ m * 3[/tex]

[tex]d= 36 \ m[/tex]

The object travels a distance of 36 meters and choice A is correct.

Answer:

h = 4.04 m

Explanation:

Given that,

Mass of a child, m = 25 kg

The speed of the child at the bottom of the swing is 8.9 m/s

We need to find the height in the air is the child is able to swing. Let the height is h. Using the conservation of energy such that,

[tex]mgh=\dfrac{1}{2}mv^2\\\\h=\dfrac{v^2}{2g}[/tex]

Put all the values,

[tex]h=\dfrac{(8.9)^2}{2\times 9.8}\\\\h=4.04\ m[/tex]

So, the child is able to go at a height of 4.04 m.

Answer:

Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery. .While energy can be transferred or transformed, the total amount of energy does not change

Answer:

That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.

Explanation:

pregunta completa

Por favor, encontrar el archivo adjunto

Solución

La velocidad instantánea está dada por,

v = dx / dt = pendiente de la curva x-t

aquí, del gráfico:

en x = 1 m ---> t = 8 s

en x = 3 m ---> t = 0 s

entonces, dx = 1-3 = -2 m

dt = 8-0 = 8 s

Entonces,

v = -2/8

v = -0,25 m / s

Dado que, pseed es una cantidad escalar.

Entonces, velocidad instantánea = | v | = 0,25 m / s

Answer:

2,340,000 J

Explanation:

Work done can be described as when energy or force is applied to an object to cause displacement

Work done is measured in joules

1 Watt = 1 Joule / second

650 watts = 650 Joules / second

convert 650 joules to seconds by multiplying by 3600

650 x 3600 = 2,340,000 J

Answer:

2 ZnS + 3O2 ---> 2ZnO + 2 SO2

Explanation:

2 ZnS + 2O2 ---> 2ZnO + SO2

There are 2 Zn atom on the LHS and 2 Zn on the RHS. Hence the Zn is balanced on both sides of the equation.

There are two S atom on the LHS but there is only one S atom on the RHS.

Hence we will balance the S atoms

2 ZnS + 2O2 ---> 2ZnO + 2 SO2

Now the oxygen is unbalanced as there are three oxygen molecule on the RHS but only two on the LHS.

Hence, the balanced equation would be

2 ZnS + 3O2 ---> 2ZnO + 2 SO2

Answer: 7.2%

Explanation:

Given

Efficiency of converting energy produced by wind into electricity is about [tex]\eta_1=40\%[/tex]

Transport of electricity efficiency [tex]\eta_2=90\%[/tex]

Fluorescent light bulb efficiency is [tex]\eta_3=20\%[/tex]

Overall efficiency is the product of all the efficiencies i.e.

[tex]\Rightarrow \eta=\eta_1\times \eta_2\times \eta_3\\\\\Rightarrow \eta=0.4\times 0.9\times 0.2\\\Rightarrow \eta=0.072\ \text{or}\ 7.2\%[/tex]

Therefore, the overall efficiency is 7.2%

Answer:

[tex]a=0.276[/tex]

Explanation:

From the question we are told that:

Mass [tex]m=98.kg[/tex]

Radius [tex]r=0.335[/tex]

Angular velocity [tex]\omega=100rpm[/tex]

Radial force of [tex]F_r=23.6 N.[/tex]

Kinetic coefficient of friction  [tex]\mu=0.192[/tex]

Generally the equation for Kinetic Force is mathematically given by

 [tex]F_k=\mu.F_r[/tex]

 [tex]F_k=0.192*23.6[/tex]

 [tex]F_k=4.5312[/tex]

Generally the equation for Torque on Center is mathematically given by

 [tex]Ia=f_k*r[/tex]

Where

 [tex]I=\frac{Mr^2}{2}[/tex]

Therefore

 [tex]a=\frac{2f_k}{Mr}[/tex]

 [tex]a=\frac{2*4.5312}{98*0.335}[/tex]

 [tex]a=0.276[/tex]

Therefore Angular acceleration of the grindstone is

[tex]a=0.276[/tex]

Answer:

Initial velocity, u = 23.33 m/s

Explanation:

Given the following data;

Acceleration = 2.5 m/s²

Distance = 4 km to meters = 4000 meters

Time = 0.8 mins to seconds = 0.8 * 60 = 48 seconds.

To find the initial velocity, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Where;

S represents the displacement or height measured in meters.

u represents the initial velocity measured in meters per seconds.

t represents the time measured in seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

4000 = u*48 + ½*2.5*48²

4000 = 48u + 1.25*2304

4000 = 48u + 2880

48u = 4000 - 2880

48u = 1120

Initial velocity, u = 1120/48

Initial velocity, u = 23.33 m/s

Answer:

v = 0.92 c

Explanation:

Here, we will use the time dilation formula from Einstein's theory of relativity to find the speed of traveling of the friend:

[tex]t =\frac{t_o}{\sqrt{1-\frac{v^2}{c^2}}} \\\\\\\sqrt{1-\frac{v^2}{c^2}}=\frac{t_o}{t}\\\\[/tex]

where,

v = speed of traveling = ?

c = speed of light

t = time of return = 10 years

t₀ = time passed on earth = 4 years

Therefore,

[tex]\sqrt{1-\frac{v^2}{c^2}} = \frac{4\ years}{10\ years}\\\\ 1-\frac{v^2}{c^2}=(\frac{2}{5})^2\\\\\frac{v^2}{c^2} = 1-\frac{4}{25}\\\\\frac{v^2}{c^2} = \frac{21}{25}\\\\v^2 = 0.84c^2\\\\[/tex]

v = 0.92 c
