Answer:

D = 26.97 m

Explanation:

given,

you walk 12.5 m in a direction exactly 19° south of west

after that 19.5 m in a direction exactly 39° west of north.

distance calculation from the starting point = ?

D₁ = d₁ cos θ

D₁ = 12.5 x cos 19°

D₁ = 11.82 m

D₂ = d₂ cos θ

D₂ = 19.5 x cos 39°

D₂ = 15.15 m

distance from the starting point

D = D₁ + D₂

D = 11.82 + 15.15

D = 26.97 m

Distance from the starting point is equal to  26.97 m

Suppose a ball had a potential energy of 5 J when you dropped it.What would be it’s kinetic energy just as it hit the ground?
timama [110]

Answer:

Due to Conservation of Energy just as the ball hits the ground it's potential energy is assumed zero

Therefore disregarding air resistance all energy is converted into potential energy.

So KE = PE  

(5 J)

Why is an iron bolt attracted to a magnet?
icang [17]

Answer:

A. When it is in a magnetic field, it becomes a temporary magnet.

Explanation:

An iron bolt is attracted to a magnet because when in a magnetic field, the iron becomes a temporary magnet.

This is because the iron aligns their electrons in the magnetic fields.

  • This causes that attraction between the magnet and the iron.
  • Metals like iron are said to be ferromagnetic
  • Unpaired electrons in iron spin in such a way that they align with the magnetic fields of the magnet.

which of the glass lenses above, when placed in air, will cause rays of light (parallel to the central axis) to converge?
777dan777 [17]

Convex lenses when placed in the air, will cause rays of light (parallel to the central axis) to converge.

Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens.

The image created is referred to be a genuine image when it is inverted relative to the object. On a screen, this kind of image can be recorded. When the object is positioned at a point farther than one focal length from the lens, a converging lens creates a true image.

A virtual image is one that cannot be produced on a screen and is formed when the image is upright in relation to the object. When an item is positioned within one focal length of a converging lens, a virtual image is created. It creates an enlarged image of the object on the same side of the lens as the image. It serves as a magnifier.

A 0.0663 kg ingot of metal is heated to 241◦C
Westkost [7]

Answer:280.216j/kg°C

Explanation:

Mass of metal=0.0663kg

mass of water=0.395kg

Final temperature=27.4°C

Temperature of metal=241°C

Temperature of water=25°C

specific heat capacity of water=4186j/kg°C

0.0663xax(241-27.4)=0.395x4186x(27.4-25)

0.0663xax213.6=0.395x4186x2.4

14.16168a=3968.328

a=3968.328 ➗ 14.16168

a=280.216j/kg°C
