Summer does not start on the same day in every country on the Earth. This statement is not true of the seasons. Hence option C is correct.
What is summer ?Summer is the hottest season of the year, lasting from spring through October. It is commonly described as the period between the summer solstice (year's longest day), June 21 or 22, and the autumnal equinox (day and night equal in duration), September 22 or 23 in the Northern Hemisphere, and December 22 or 23 in the Southern Hemisphere. Summer temperatures differ from other seasons only in the middle and high latitudes; temperatures in the tropical areas fluctuate little from month to month. See season for information on the physical reasons of the seasons.
Summer is connected with development and maturity in European languages, particularly that of cultivated plants, and indeed, summer is the season of highest plant growth in countries with sufficient summer rainfall. Many civilizations have utilised festivals and ceremonies to commemorate summer in appreciation of its role in food production.

Sedimentary rocks are over 10,000 feet thick in some areas.
true or fasle
Answer: True
Explanation:
Sedimentary rocks are, in average, 1800m thick, where 1m = 3.28084 ft
so 1800 meters are equivalent to 1800*3.2 ft = 5760 ft.
But this is the average, there are some areas with no sedimentary rocks at all, and some areas, like the Texas and Lousiana Gulf coasts, that have around 20,000m of sedimentary rock, and knowing that 1m = 3.2ft
20,000m is a lot more than 10,000 feet, so the statement is true.

Which of the following adaptations would help a tree-dwelling nocturnal scavenger survive in its environment?
Answer:
Night vision
Explanation:
Nocturnal animals have generally bigger eyes than humans and have mostly a tubular shape. This makes more light enter the retina which makes it possible for animals to see at night. Nocturnal animals do all of their activities at night so they need night vision to survive. With night vision they can hunt for food, run away from predators.
The color of fur helps animals to camouflage themselves this would be of no use to nocturnal animals.
Furry heels and short snouts also would be of no use to nocturnal animals.

Denise is conducting a physics experiment to measure the acceleration of a falling object when it slows down and comes to a stop. She drops a wooden block with a mass od 0.5 kilograms on a sensor on the floor. The sensor measures the force of the impact as 4.9 newtons. Whats the acceleration of the wooden block wgen it hits the sensor
Answer:
[tex]a = 9.8 m/s^2[/tex]
Explanation:
As we know that here given parameters are
[tex]mass = 0.5 kg[/tex]
also we know that force of impact on the floor is given as
[tex]F = 4.9 N[/tex]
now we know by the Newton's 2nd law says that the net force on an object is product of mass and its acceleration
it is given by
[tex]F = ma[/tex]
now we have
[tex]a = \frac{F}{m}[/tex]
[tex]a = \frac{4.9}{0.5}[/tex]
[tex]a = 9.8 m/s^2[/tex]

The greatest displacement is either option A or C, as both result in the person being displaced by 3 meters north of their starting point.
Explanation:The question asks which of the given options describes the greatest displacement. Displacement is a vector quantity that describes the change in position of an object. It is important to understand that displacement takes into account the initial and final positions, not the total distance traveled.
A) walking 3m east, then walking 3m north, then 3m westB) walking 3m east, then 3m south, then 3m northC) walking 3m north, then 3m south, then walking 3m northD) walking 3m north, then 3m west, then 3m southFor option A, the displacement would result in the person being 3m north from their starting point, since the east and west movements cancel out. Option B results in the person being 3m east of the starting point, as the south and north movements cancel each other out. Option C essentially brings the person back to their starting point after the first two movements, and then displaces them 3m north, similar to option A. Finally, option D involves the person moving 3m in each of the cardinal directions, which would bring them right back to their starting point, resulting in a displacement of 0 meters.
The correct answer is either option A or C, as both result in the greatest displacement, which is 3 meters north.

Explain how a microwave oven heats a cup of water.
A microwave oven heats water by emitting microwaves that cause water molecules to rotate and create thermal energy, efficiently heating the liquid due to the molecular freedom in the water.
A microwave oven heats a cup of water by utilizing microwaves at a frequency of 2.45 GHz, which excite the water molecules in the cup. These microwaves create an oscillating electric field that exerts a torque on the dipolar water molecules, causing them to rotate aggressively. This doesn't substantially heat the container as materials like plastic and glass lack these dipolar water molecules. This molecular motion translates into thermal energy due to friction and collisions between molecules, thus heating the water. It's observed that heating liquids like water is much more efficient than solids due to the greater freedom of movement that allows the molecules in liquids to more readily absorb and disperse the energy from the microwaves.
what is the coefficient of static friction if it takes 34n of force to movea box that weighs 67n?
The coefficient of static friction would be 0.507 if it takes 34 Newtons of force to move a box that weighs 67 Newtons.
What is friction?Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.
As given in the problem we have to find out the coefficient of static friction if it takes 34 Newtons of force to move a box that weighs 67 Newtons.
The normal force acting on the box = weight of the box
=67 Newtons
The friction force = coefficient of the friction × Normal force
34 = coefficient of the friction × 67
The coefficient of the friction = 34/ 67
=0.507
Thus, the coefficient of static friction would be 0.507 if it takes 34 Newtons of force to move a box that weighs 67 Newtons.

In order to scientifically demonstrate that Earth is spherical, one can measure the Earth's curvature, conduct gravity experiments, utilize satellite imagery, and observe the change in constellations at different latitudes.
Explanation:The question that could be best answered using scientific inquiry about the discovery of the Earth revolving around the sun would be: Give four ways to demonstrate that Earth is spherical.
Measure the Earth's curvature using a long-distance view, such as observing a ship disappearing over the horizon.Conduct experiments with gravity, such as observing the shape of water in a container or using a plumb line to measure verticality.Utilize satellite imagery or photos taken from space to show the Earth's spherical shape.Observe the change in constellations as you move away from the equator, which can only be explained by Earth's sphericity.Why do oceanographers study Meddies?
