Answer:

acceleration =

[tex]8.33ms {}^{ - 2} [/tex]

Explanation:

we know,

force = mass × acceleration

8.33 m/s² quickly would a 60kg object accelerate if the person applied a 500N force.

Acceleration the rate at which speed and direction of a moving object vary over time. A point or object moving straight ahead is accelerated whenever it accelerates or decelerates. Even if the speed remains constant, motion on the a circle accelerates so because direction is constantly shifting.

An item that is slowing down will always have a negative acceleration if the current direction of motion is constantly selected as positive.

Force = mass × acceleration

500 = 60 × a

a = 500 / 60

a = 50 / 6

a = 8.33 m/s²

Answer:

Ф = 4.5176x10⁵ N . m² / C

Explanation:

In this case, we need to use two expressions in order to calculate the electric flux of the sphere.

First the Electric flux is calculated using this expression:

Ф = E * A  (1)

Where:

E: Electric field

A: Area of the sphere

To get the electric field E, we use this expression:

E = K * q / r²    (2)

If we replace (2) into (1) we have the following:

Ф = K * q * A / r²    (3)

Finally, we need to know the expression to get the area of a sphere which is the following:

A = 4πr²   (4)

Replacing into (3):}

Ф = K * Q * 4πr² / r²       discarting r²:

Ф = K * Q * 4π   (5)

Now, all we need to do is replace the given values and solve for the electric flux of the sphere:

Ф = 8.98755x10⁹ * 4x10⁻⁶ * 4 * π

Answer:

22 s

Explanation:

time = distance / velocity

We know that distance = 770 m and velocity = 35 m/s.

t = d / v

t = 770 m / 35 m/s

t = 22 s

It takes 22 seconds to cover 770 m. Hope this helps, thank you !!

Answer:

industrial revolution

Explanation:

Answer:

a. Acceleration = 1.75 m/s²

b. Force = 105 Newton.

Explanation:

Given the following data:

Mass = 60kg

Final velocity = 7m/s

Time = 4 seconds

Required to find the acceleration and force of the body;

a. To find the acceleration;

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Where;

Since the elevator is starting from rest, its initial velocity is equal to 0m/s.

Substituting into the equation, we have;

[tex]Acceleration = \frac{7 - 0}{4}[/tex]

[tex]Acceleration = \frac{7}{4}[/tex]

Acceleration = 1.75 m/s²

b. To find the force;

[tex] Force = mass * acceleration [/tex]

Substituting into the equation, we have;

[tex] Force = 60 * 1.75[/tex]

Force = 105 Newton.

Answer:

The frequency of the wave would come out to be 110 Hz.

Frequency is the number of completed wave cycles per second. By using the simplest frequency equation, f = 1 / T, you get the answer I provided above.

The train has covered 13,500 meters of track.

We don't know its position, because we don't know where it started from, and we don't know how straight the track is.

Answer: 294J

Explanation:

[tex]U_g=mg(y_f-y_i)[/tex]

[tex]U_g=(15)(9.8)(2-0)=294J[/tex]

Answer:

294.3 J

Explanation:

U = mgh

U = energy

m = mass

g = gravity

h = height

so

U = 15kg * 9.81 m/s^2 * 2m

294.3 J (joules) [kg *m^2/s^2]

Answer:

The answer is below

Explanation:

a) According to Newton's law of motion, the distance travelled by a body going upward can be calculated using the formula:

v² = u² - 2gh

where v is the final velocity, u is the initial velocity, g is the acceleration due to gravity and h is the height of the ball.

g = 10 m/s², u = 25 m/s, v = 11 m/s

Substituting:

11² = 25² - 2(10)h

20h = 25² - 11²

20h = 504

h = 25.2 m

b) The time (t) can be gotten using:

v = u - gt

Substituting

11 = 25 - 10t

10t = 25 - 11

10t = 14

t = 1.4 s

c) the graph were plotted using an online graphing tool

Snow and sleet when they fall to the ground is gravitational force.

"While snow, sleet and freezing rain are familiar precipitation types to most people, one that may be lesser known is graupel, also known as snow pellets. Graupel forms when snowflakes are coated with a layer of ice. Graupel is typically white and opaque. A comparison of sleet and graupel."

"According to Newton's universal law of gravitation, The force of attraction between any two bodies is directly proportional to the product of their masses and is inversely proportional to the square of the distance between them."

Answer:

The force between Earth and the moon is 1.99x10²⁶ N.

Explanation:

The force between Earth and the moon can be found using the Gravitational Force equation:

[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} [/tex]

Where:

d: is the distance between Earth and the moon = 3.84x10⁵ m

G: is the gravitational constant = 6.67x10⁻¹¹ Nm²/kg²

[tex]m_{E}[/tex]: is the Earth's mass = 5.98x10²⁴ kg

[tex]m_{m}[/tex]: is the moon's mass = 7.36x10²² kg

Hence, the force is:

[tex] F_{g} = \frac{Gm_{E}m_{m}}{d^{2}} = \frac{6.67 \cdot 10^{-11} Nm^{2}/kg^{2}*5.98\cdot 10^{24} kg*7.36\cdot 10^{22} kg}{(3.84\cdot 10^{5} m)^{2}} = 1.99 \cdot 10^{26} N [/tex]

Therefore, the force between Earth and the moon is 1.99x10²⁶ N.
