ESSAY: PROPHECY
kogti [31]

The two Old Testament chapters filled with prophecies concerning Jesus Christ are:

Isaiah 9:6: Here, Isaiah was said to have prophesies that Jesus Christ will be born and he will come as a baby; Jesus was known to be called by several names here such as the Prince of peace.

Micah 5:2L Here, Micah was said to have prophesies that Jesus will be born in a town that is called  Bethlehem.

<h3>What is the message of Isaiah 9?</h3>

The kind of message is one that can be seen mostly in Isaiah 9:1-7. Isaiah  was known to be a prophet who was said to have announced that there is what we see presently gloom and distress and there a time will arise or come to pass when there will be happiness, joy and salvation.

The reason for the above is because a child will be born who will be the savior of the whole world and through him, the Rod of the Oppressor will be destroyed.

A plane is flying horizontally at a height of 500 m and a constant speed of 429 km/h when an object is projected downward at an
Strike441 [17]

Answer:  the average vertical component of velocity between the object's release and its striking the ground is 49.5 m/s or 178 km/h


Explanation:


1) The motion of an object under the action of gravity, when air resistance is neglected is called projectile motion. The path is a curve with the form of  a parabola.


2) The equations that rule that motion are:

  • Horizontal speed:
  • Vx = Vox = constant.
  • In this case it is the same horizontal speed of the plane at the moment when the object was proyected. Vx = 429 km/h.
  • Vertical speed:

         Vy = Voy + gt

         d = yo - Voy×t - gt² / 2

         Vy² = Voy² - 2gd

  • Since, you know Voy =0, g = 9.81 m/s², and d = 500m, you can use the last equation, leading to:

        Vy² = 2(9.81m/s²)(500m) = 9,810 m²/s² ⇒ Vy = √(9,810 m²/s²) = 99 m/s


3) As per definition the average velocity is displacement / time, so you need to find the time to reach the ground.

  • You can use the formula  Vy = Voy + gt
  • Clear t: t = (Vy - Voy) / g = (99 m/s - 0) / 9.81 m/s = 10.1s

  • Average vertical velocity = 500 m / 10.1s = 49.5 m/s.
  • You can convert to km/h: 49.5 m/s × 1km/1,000m × 3600s/h = 178 km/h

4) Conclusion: the average vertical component of velocity between the object's release and its striking the ground is 49.5 m/s or 178 km/h

Harriet is told by her doctor that her heart rate is 70.0 beats per minute. If Harriet's average blood flow in the aorta during
vfiekz [6]

Answer:

12.9 mm

Explanation:

From v = fλ where v = speed of wave = blood flow rate = 1.5 × 10⁻² m/s and f = frequency of wave = heart rate = 70 beats per minute = 70/60 beats per second and λ = wavelength of waves in Harriet's aorta.

λ = v/f = 1.5 × 10⁻² m/s ÷ 70/60 beats per second

  = 6 × 1.5 × 10⁻²/7  

  = 1.29 × 10⁻² m

  = 12.9 mm

A bag of groceries has a weight of 44 newtons. Find its approximate weight in kilograms.
Artist 52 [7]
You cannot convert newtons to kilograms, or pounds to kilograms,
or kilograms to pounds or newtons.

Newtons and pounds are units of FORCE.  Kilogram is a unit of MASS.


If an object weighs 44 newtons on Mars,
then its mass is about 13.5 kilograms

If an object weighs 44 newtons on the Moon,
then its mass is about 27.2 kilograms.

If an object weighs 44 newtons on Earth,
then its mass is about 4.5 kilograms.
