Answer:

Because the angle of the sun moves/rotates in the summer, the sun's rays move their angle and impact the earth.

Ball a of mass 5.0 kilograms moving at 20 meters per second collides with ball b of unknown mass moving at 10 meters per second
RUDIKE [14]

M = mass of the ball A = 5.0 kg

m = mass of the ball B = ?

V = initial velocity of the ball A before collision = 20 m/s

v = initial velocity of the ball B  before collision = 10 m/s

V' = final velocity of the ball A after collision = 10 m/s

v' = final velocity of the ball B after collision = 15 m/s

using conservation of momentum

M V + m v = M V' + m v'

(5.0) (20) + m (10) = (5.0) (10) + m (15)

100 + 10 m= 50 + 15 m

5 m = 50

m= 10 m/s

Animals have different types of respiratory systems depending on the environment of their habitat. Fish live in the water and us
VMariaS [17]

Answer:

1. Both are respiratory organs found in vertebrates.

2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.

3. Respiratory membranes present in both make the exchange of gases easier.

4. Blood vessels found around them enable the breathing process.

Explanation:

Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory  membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.

The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.

Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.

A golfer takes three putts to get the ball into the hole. The first putt displaces the ball 3.32 m north, the second 1.57 m sout
bixtya [17]

Answer:

The answer to the question is

The magnitude of the displacement needed to get the ball into the hole in just one putt is 1.746m in the direction of 23.41° north east

Explanation:

With trigonometric relation and the attached diagram we have

From the diagram the location of the hole is 3.32m- (1.57 cos45 +0.78co45)m North and

1.57sin 45 – 0.78 sin 45 meters west

1.658m north and

0.55m east

Thus the direction of the hole is 26.41 degrees  

North east

The magbitude of the displacement is  displacement is gotten from the relation diplacement of x and y =√(x²+y²)

\sqrt{1.658^{2} +0.55^{2}  } = 1.746 m∠26.41°

Why wil an ice cube melt if it is compressed even if it remains at the same temp
Gnoma [55]
No, it will only melt if the temperature is lowered. If you compress it, it will change the shape, but it will not change the state it is in (i.e. solid).
