MAVERICK [17]3 years ago

The applied force is the force from an external agent that tries to start the motion or stop the motion. Since, the block is being dragged in the horizontal direction, the applied force will be spring balance force because it drags the block to the left. Hence, it is the applied force. The forces in the vertical direction are gravity and normal force and the dotted force is frictional force.

Answer: The spring scale drags the box.

The spring scale dragging the box, since applied force is a force acting on an object due to a person or another object.

Even though the table is an object, the table pushing up is the normal force, which is perpendicular to the contact force.

In a double-slit experiment, light from two monochromatic light sources passes through the same double slit. The light from the
PtichkaEL [24]

Answer:

533.33 nm

Explanation:

Since dsinθ = mλ  for each slit, where m = order of slit and λ = wavelength of light. Let m' = 10 th order fringe of the first slit of wavelength of light, λ = 640 nm and m"= 12 th order fringe of the second slight of wavelength of light, λ'.

Since the fringes coincide,

m'λ = m"λ'

λ' = m'λ/m"

= 10 × 640 nm/12

= 6400 nm/12

= 533.33 nm

A fisherman is fishing from a bridge and is using a "42.0-N test line." In other words, the line will sustain a maximum force of
lara31 [8.8K]

Answer:

(a) 42 N

(b)36.7 N

Explanation:

Nomenclature

F= force test line (N)

W : fish weight  (N)

Problem development

(a) Calculating of weight of the heaviest fish that can be pulled up vertically, when the line is reeled in at constant speed

We apply Newton's first law of equlibrio because the system moves at constant speed:

∑Fy =0

F-W= 0

42N -W =0  

W = 42N

(b) Calculating of weight of the heaviest fish that can be pulled up vertically, when the line is reeled with an acceleration whose magnitude is 1.41 m/s²

We apply Newton's second law because the system moves at constant acceleration:

 m= W/g , m= W/9.8 ,  m:fish mass , W: fish weight g:acceleration due to gravity

∑Fy =m*a

m= W/g , m= W/9.8 ,  m:fish mass , W: fish weight g:acceleration due to gravity

F-W= ( W/9.8 )*a

42-W=  ( W/9.8 )*1.41

42= W+0.1439W

42=1.1439W

W= 42/1.1439

W= 36.7  N

meriva

Answer:

4948020

Explanation:

(6.9*10-6)(770*102)

<u>Multiply  6.9  by  10 . </u>

( 69 − 6 ) ( 770 ⋅ 102 )

<u>Subtract  6  from  69 . </u>

63 ( 770 ⋅ 102 )

<u>Multiply  770  by 102 . </u>

63 ⋅ 78540

<u>Multiply  63  by  78540 . </u>
