Answer:

force = 21 kg m/s^2 = 21 N

Step-by-step explanation:

If an object has mass (m) 3 kg, and its acceleration (a) is 7 m/s^2, its force is given by Newton's second law of motion: Force = M * a

Force = 3 kg * 7 m/s^2= 21 kg * m/s^2

This combinations of units (kg * m/s^2) is defined as Newtons in physics and abbreviated "N".

So we can say that the force on this object is of magnitude 21 N

MakcuM [25]

Answer:

current volume of the water = 785.714 in²

Height of new container = 10 inches

Step-by-step explanation:

Radius of the container = 5 inches

Height of the container = 20 inches

Volume of the container = πR²H = (22/7) × 5² × 20 = 1571.428571428 in²

Since the container is half filled with water, volume of the water = 1571.428571428 ÷ 2 = 785.714 in²

b. Volume of cylinder = πR²H = volume of water from first container = 785.714 in²

Hence 785.714 = (22/7) × 5² × H

H = (785.714) ÷ [(22/7) × 25] = 10 inches

Height of new container = 10 inches

PLEASE HELP FAST!! |x+5|>-1, what is x (answer in x equals to)

Daniel [21]

$(x+5)>-1 or -(x+5)>-1$

$x>-1-5 or x$

$x>-6 or x$

This gives us the union of two sets

$(-∞,-4) U (-6,+∞)$

$=(-∞,+∞)$

x belongs to all real numbers
