What is the resultant force of the free body diagram?

Physics
1 answer:
GaryK [48]3 years ago
4 0

1) Magnitude of the net force: 20.8 N

2) Angle: 35.2^{\circ} clockwise from positive x-direction

Explanation:

1)

First of all, we need to find the components of the resultant force along the horizontal and vertical direction.

We observe that there are two forces acting along the horizontal direction:

F_1=33 N\\F_2 = 16 N

We notice that they act in opposite directions, so the net force in the horizontal direction is the difference between these two forces:

F_x =F_1-F_2=33-16=17 N (to the right)

Instead, there is only one force acting in the vertical direction, so the net force in the vertical direction is:

F_y=F_3=12 N (downward)

Therefore, the magnitude of the net force can be found by using Pythagorean's theorem:

F=\sqrt{F_x^2+F_y^2}=\sqrt{17^2+12^2}=20.8 N

2)

Now we have to find the angle of the resultant net force. We can do it by using the following equation:

tan \theta = \frac{F_y}{F_x}

where

\theta is the angle, measured as clockwise from the positive x-direction (because the vertical net force is downward)

F_y = 12 N is the vertical net force

F_x=17 N is the horizontal net force

Solving, we find:

tan \theta=\frac{12}{17}=0.706

And so the angle is

\theta=tan^{-1}(0.706)=35.2^{\circ}

In a direction down with respect to the right.

You have learned of two fundamental units that are not vector quantities. Which are they?
Mila [183]

Answer:

Mass and time are not vector quantities .

Explanation:

All the physical quantities can be classified into two major categories that is :

  • Scalar
  • Vector

Scalar quantities

  • They are those that describes only  the magnitude and they are regarded as incomplete quantities as they don't provide complete information.

               For example :  Speed ,Mass, Time etc

Vector quantities

  • They are complete quantities that can be described in magnitude as well as direction .

         For example : Velocity ,gravity ,Acceleration etc

Consider a single photon with a wavelength of lambda, a frequency of nu, and an energy of E. What is the wavelength, frequency,
BARSIC [14]

Answer: lambda \lambda, nu \nu, and 100E

Explanation:

The energy E of a photon is given by:

E=h\nu   (1)

Where:

h is the Planck constant

nu is the frequency

On the other hand, we have an expression that relates the frequency of the photn with its wavelength \lambda:

nu=\frac{c}{\lambda} (2) where c is the speed of light

Substituting (2) in (1):

E=h\frac{c}{\lambda}   (3) This is the energy for a single photon

For 100 photons, the energy is:

100E=100(h\frac{c}{\lambda})=100h\nu   (3)

Where the wavelength and the frequency of the light remains constant.

Therefore, the answer is:

\lambda, \nu, and 100E
