Answer:

The period of motion is 1.26x10⁻⁶ s.

Explanation:

The period of motion can be found as follows:

[tex] \omega = \frac{2 \pi}{T} [/tex]

Where:

ω is the angular speed

T is the period

The angular speed is related to tangential speed (v):

[tex] v = \omega r [/tex]

r is the radius

Hence, the period is:

[tex] T = \frac{2 \pi r}{v} = \frac{2 \pi 0.2 m}{10^{6} m/s} = 1.26 \cdot 10^{-6} s [/tex]

Therefore, the period of motion is 1.26x10⁻⁶ s.

See attachment for calculations

Answer:

A = -14.87 i ^ + 8.42 j ^ + 0 k ^

B = -25.41 i ^ -12.0 j ^ + 0 k ^

Explanation:

For this exercise let's use trigonometry by decomposing to vectors

vector A

module 17.1 with an angle of 150.5 counterclockwise.

         Sin 150.5 = [tex]A_{y}[/tex] / A

         cos 150.5 = Ax / A

         A_{y} = A sin 150.5 = 17.1 sin 150.5

         Aₓ = A cos 1505 = 172 cos 150.5

         A_{y} = 8,420

         Aₓ = -14.870

the vector is

          A = -14.87 i ^ + 8.42 j ^ + 0 k ^

Vector B

         [tex]B_{y}[/tex] = 28.1 sin 205.3

         Bₓ = 28.1 cos 205.3

         B_{y} = -12.009

          Bₓ = -25.405

the vector is

          B = -25.41 i ^ -12.0 j ^ + 0 k ^

Answer:

The distance is, y = 489.5 [m/s]

Explanation:

To solve this problem we can use the following equation of kinematics.

[tex]v_{f}^{2}= v_{i}^{2}+(2*g*y)[/tex]

where:

Vf = final velocity = 98 [m/s]

Vi = initial velocity = 0

g = gravity acceleration = 9.81 [m/s^2]

y = distance [m]

(98^2) = 0 + (2*9.81*y)

Note: the positive sign of the equation means that the acceleration of gravity acts in the direction of the movement of the object.

9604 = 19.62*y

y = 489.5 [m/s]

Answer:

Decrease the mass.

Explanation:

By Newton's Second Law we know that net force exerted on a given system equals the rate of change of linear momentum ([tex]P[/tex]) in time.

[tex]F = \frac{dP}{dt}[/tex] (Eq. 1)

When mass of the system has a constant mass, this net force ([tex]F[/tex]) is reduced to its mass ([tex]m[/tex]) multiplied by acceleration ([tex]a[/tex]):

[tex]F = m\cdot a[/tex] (Eq. 2)

If we keep net force exerted on system constant, then a decrease on mass is compensated by an increase in acceleration. Hence, correct answer is: Decrease the mass.

Explanation:

Answer:

Explanation:

Please see attached a detailed drawing of the force and line diagram for your reference.

Given data

weight W=96N

Fx=20N

Fy=25N

acceleration a= -0.9m/s^2----slowing down indicate negative

W=mg= 96N

Fk= kinetic friction= μkN

where N= normal reaction

from newtons second law

F=ma

x-----Fx-Fk=ma

Fk=Fx-ma

y----N-Fy-W=0

N=25+96

N=121N

so

Fx-μkN=ma

20-μkN=(96/9.81)-0.9

20-μkN=-86.4/9.81

20-μkN=-8.80

-μkN=-20-8.8

μkN=20+8.8

μk=28.8/N

μk=28.8/121

μk=0.238

μk=0.24

Answer:

the electric force increases because the amount of charge has a direct relationship to the force

Increasing the amount of charge on an object will increase the electric force it exerts on another charged object because the amount of charge has a direct relationship to the force. Therefore, option (B) is correct.

Mathematically, the amount of charge on an object due to the effect of the force that is exerted on it can be calculated by using the formula mentioned below:

F = E×q

Where F is the electric force, E is the energy, and q is the charge.

The electric force between charged particles at rest is known as electrostatic force. The magnitude of the electric force between point charges is directly proportional to the multiplication of the charges and inversely proportional to the distance between them.

Therefore, increasing the amount of charge on an object would increase the electric force because the amount of charge has a direct relationship with the force.

Answer:coherent light

Explanation:

Answer:

B

Explanation:

Answer:

a = 9.8 m/s²

Explanation:

Here, we will use the first equation of motion to determine the acceleration of the falling rock. The first equation of motion is written as follows:

Vf = Vi + at

where,

Vf = Final Velocity of the falling rock = 31.6 m/s

Vi = Initial Velocity of the falling rock = 12 m/s

a = acceleration = ?

t = time interval = 2 s

Therefore,

31.6 m/s = 12 m/s + a(2 s)

a = (31.6 m/s - 12 m/s)/(2 s)

a = 9.8 m/s²

Given:

We know the relation,

→ [tex]V_f = V_i +at[/tex]

By substituting the values,

 [tex]31.6 = 12+a(2)[/tex]

     [tex]a = \frac{31.6-12}{2}[/tex]

        [tex]= \frac{19.6}{2}[/tex]

        [tex]= 9.8 \ m/s^2[/tex]

Thus the answer above is correct.

Answer:

"An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. ... When an electric current flows through the coils, the electromagnet creates a magnetic field which pulls the armature towards it, causing the hammer to strike the bell."

The acceleration of the object is 11.11 m/[tex]s^2[/tex] (approximately).

The rate of change of velocity of a body with respect to time is known as acceleration. Due to having both magnitude and direction, it is a vector quantity having SI unit m/s^2.

Given parameter,

The mass of the object, m = 45 Kg.

Net force acting on the object, F = 500 N.

Acceleration of the object, a= ?

From Newton's 2nd law of motion,

Force = mass × acceleration

⇒ F = ma

⇒ a = F/m

= 500 N /45 Kg

= 11.11 m/s^2. (approximate)

Hence, the approximate value of acceleration of the object, a = 11.11 m/s^2.

Answer:

The answer is A

Answer:

A. amplitude

Explanation:

Answer:

The correct response is "No". The further explanation is given below.

Explanation:

The given values are:

Angle

[tex]\theta = 30^{\circ}[/tex]

Distance

d = 20 m

Speed

s = 8.0 m/s

Now,

⇒  [tex]y(t) = \frac{1}{2}\times a\times t^2 + v0\times t\times (sin \theta)[/tex]

    [tex]0 = -4.9t^2 + v0\times t\times (sin 30)[/tex]

    [tex]x = v0\times (cos \theta)\times t[/tex]

    [tex]65 = v0\times (cos 30)\times t[/tex]

    [tex]v0\times t = \frac{65}{Cos30}[/tex]

    [tex]0 = -4.9t^2 + 65\times \frac{sin30}{cos30}[/tex]

    [tex]t = 2.767 \ sec[/tex]

So,

⇒  [tex]d = r\times t[/tex]

    [tex]20 = 8\times t[/tex]

      [tex]t=2.5 \ sec[/tex]

Therefore, 2.5 < 2.767, so it won't get there.
