A miners' cage of mass 420 kg contains 3 miners of total mass 280 kg. The cage
svp [43]

Answer:

5817 Newtons.

Step-by-step explanation:

Total mass of the cage + the miners = 700 Kg which is a downward force of  700g N.

The net downward force = 700g - T where T is the tension (force) in the cable. The g = acceleration due to gravity = 9.81 m s-2.

We  calculate the  acceleration of the cage by using an equation of motion:

Distance = ut + 1/2 a t^2     where u = initial velocity , t = time and a = acceleration:

75 = 0(t) + 1/2 a (10^2)

50a =  75

a = 1.5 m s-2.

So using Newtons second law of motion

Force = mass * acceleration:

700*9.81 - T = 700 * 1.5

T = 700 * 9.81 - 700*1.5

= 5817 N.

The slope that passes through the point (-2,-4) and (-3,-8) is
enot [183]

Answer:

y=4x+b (four being the slope)

Step-by-step explanation:

So lets use

ΔY/ΔX

or the y2-y1 over x2-x1

\frac{-8+4}{-3+2}

\frac{-4}{-1}

Therefore, the slope is 4

❥\Large\pmb{ \underline {\tt Answer}}

So we can only find x if other two angles of triangle is given.

In angle B as u can see boxed shape angle is there then it probably means it's a 90° angle.

We know sum of angles of triangle = 180°

{Reson :-

There's a formula to fund sum of angles of figure

  • (n-2) × 180
  • (3 -2) × 180
  • 1 × 180
  • 180°

}

Now Let's proceed

\boxed{ \rm Side_1+Side_2+Side_3 = 180\degree}

Fill all the given values

\dashrightarrow \tt 90 \degree + 55 \degree + c = 180 \degree

\\  \\

\dashrightarrow \tt 145\degree + c = 180 \degree

\\  \\

\dashrightarrow \tt  c = 180  \degree - 145\degree

\\  \\

\dashrightarrow \tt  c = 35\degree

\\  \\

Value of x = 35°
