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.

You have 896 grams of a radioactive
Margarita [4]

Every 56 seconds, the radioactive substance is divided in half.

224 / 56 = 4

We need to cut the substance in half 4 times.

896 / 2 = 448

448 / 2 = 224

224 / 2 = 112

112 / 2 = 56

After 224 seconds, there will be 56 grams of the radioactive substance left over

WIll give brainliest Use the information given to answer the question.
MaRussiya [10]

Answer:

x²-12x+36

Step-by-step explanation:

an expression in the form (a-b)² is expanded to the form a²-2ab+b²

you can also expand it to (x-6)×(x-6) then multiply the first term by the first the outer term by the outer term the inner term by the inner term and the last term by the last term (foil)

the first terms are x and x = x² the outer terms are x and -6 = -6x the inner terms are also x and -6 = -6x

the last terms are 6 and 6 = 36

adding all the four products =

x²-12x+36

What is y+8=-5(x+3) in standard form
Papessa [141]

Answer:

-5x + y = -27

Step-by-step explanation:

Equation: y+8 = -5(x+3)

Standard form is (ax + by = c)

We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.

y + 8 = -5 (x + 3)

y + 8 = -5x -15

y = -5x - 27

THE ANSWER IS :

-5x + y = -27
