Complete Question

The complete question is shown on the first uploaded image

Answer:

   The value is \vec  B  =  2, -3

Explanation:

Looking at the graph in the diagram we see each unit is equal to 1 both in the x axis and in the y- axis

  Now the value of B along the x axis is  

         B_x = 2

and along the y axis the value  is  

        B_y  = -3

Hence the vector B is

     \vec  B  =(B_x  , B_y)=  ( 2, -3)

A 200 g block is pressed against a spring of force constant 1.40 kN/m until the block compresses the spring 10.0 cm. The spring
tino4ka555 [31]

Answer:

Explanation:

This problem bothers on the energy stored in a spring in relation to conservation of energy

Given data

Mass of block m =200g

To kg= 200/1000= 0.2kg

Spring constant k = 1.4kN/m

=1400N/m

Compression x= 10cm

In meter x=10/100 = 0.1m

Using energy considerations or energy conservation principles

The potential energy stored in the spring equals the kinetic energy with which the block move away from the spring

Potential Energy stored in spring

P.E=1/2kx^2

Kinetic energy of the block

K.E =1/mv^2

Where v = velocity of the block

K.E=P.E (energy consideration)

1/2kx^2=1/mv^2

Kx^2= mv^2

Solving for v we have

v^2= (kx^2)/m

v^2= (1400*0.1^2)/0.2

v^2= (14)/0.2

v^2= 70

v= √70

v= 8.36m/s

a. Distance moved if the ramp exerts no force on the block

Is

S= v^2/2gsinθ

Assuming g= 9. 81m/s^2

S= (8.36)^2/2*9.81*sin60

S= 69.88/19.62*0.866

S= 69.88/16.99

S= 4.11m

What happens to a light if the switch is turned off in the circuit?
lukranit [14]

In a parallel circuit nothing happens. All the other lights stay on but if it was a series circuit ALL the lights would turn off at one time.

If there is an ABCD question I can answer that but I wasn't sure so I just said this

Hope it is helpful :)

Which of the following represents a case in which you are not accelerating? View Available Hint(s) Which of the following repres
padilas [110]

Answer:

4) Driving in a straight line at 60 miles per hour

Explanation:

1) Driving 60 miles per hour around a curve

2) Going from 0 to 60 miles per hour in 10 seconds

3) Slamming on the brakes to come to a stop at a stop sign

4) Driving in a straight line at 60 miles per hour

1) The speed is constant here, but in circular motion you have an acceleration that is v^2/r, where v is the speed and r the radius

2) You are accelerating from 0 to 60

3) You are desaccelerating

4) constant speed , no acceleration

In an experiment different wavelengths of light, all able to eject photoelectrons, shine on a freshly prepared (oxide-free) zinc
topjm [15]

Answer:

the energy of the photons is greater than the work function of the zinc oxide.

                     h f> = Ф

Explanation:

In this experiment on the photoelectric effect, it is explained by the Einstein relation that considers the light beam formed by discrete energy packages.

                    K_max = h f - Ф

in the exercise phase, they indicate that different wavelengths can inject electrons, so the energy of the photons is greater than the work function of the zinc oxide.

                     h f > = Ф
