Explanation:

Autumn start in different months of the year in North America and South America due to the tilt in earth's axis creating different distance from the sun for different regions.

A season is a time of year that can be identified by unique climatic features. Spring, summer, fall, and winter all occur in regular succession. Each has distinctive seasonal variations in light, temperature, and weather.

Each seasons starts at different month in two hemispheres of  earth. This s due to the fact that, earth's axis is not perfectly circular and it is slightly tilted towards sun.

When the Northern Hemisphere is tilted toward the sun in June, more of the day is spent being illuminated by the sun's rays than it is in winter. As a result, there are longer daylight hours.

There are fewer daylight hours in December because the Northern Hemisphere is tilted away from the sun. Similarly the autumn season also differ from that of the southern hemisphere.

Answer:

A container holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg. What will be its volume if the temperature increases by 35° C?

✓ For this problem we would use the equation for Charles' Law which compares the direct relationship between Volume and Temperature when Pressure is …

Americium-241  isotope would be expected to have the longest half-life. Hence, option (D) is correct.

In radioactivity, the half-life is the time required for one-half of a radioactive sample's atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time required for the number of disintegrations per second of a radioactive material to decrease by one-half.

According to given data:

Rate of decay is the highest for Mercury-194, hence, its half-life is least. Then rate of decay is lowest for  Americium-241, hence, its half-life is the longest. Hence, option (D) is correct.

The order of half-life according to the data is:

Americium-241 > Silver-108 > Californium-249 >  Mercury-194.

The net force which has to be applied on the arrow of 0.07kg to accelerate at the rate of 4000m/s² is 280N. Thus, the correct option is A.

A force is an influence which can be a push or a pull that can change the motion of an object. A force can cause an object with some mass to change the velocity, i.e., results into acceleration. A force is a vector quantity as it has both the magnitude and direction.

Force applied on an object can be calculated by the formula:

f = m × a

where, f = force applied,

m = mass of the object,

a = acceleration of the object

Therefore, the force applied on the arrow is:

f = m × a

m = 0.07kg

a = 4000m/s²

f = 0.07 × 4000

f = 280N

Therefore, the correct option is A.

Answer:

Its acceleration is 30 mph.

Explanation:

The true of the ball's motion will be that the velocity is 90 mph to the west. Velocity is the vector quantity. Because it shows the direction.

Acceleration is defined as the rate of change of the velocity of the body. Its unit is m/sec². It is a vector quantity. It requires both magnitudes and direction to define.

The given data in the problem is

The velocity of  baseball is,V=  90 mph

The distance travelled in mile is; d=0.0113636 mile

The time period is obtained as;

[tex]\rm t = \frac{d}{v} \\\\ \rm t = \frac{0.0113636}{90} \\\\ t=1.2 \times 10^{-4} \ hr[/tex]

The acceleration is obtained is 0.00108 mile/hr².

Hence, the true of the ball's motion will be that the velocity is 90 mph to the west.

Answer:

The particle model of matter is one of the most useful scientific models because it describes matter in all three states. Understanding how the particles of matter behave is vital if we hope to understand science!

The model also helps us to understand what happens to the particles when matter changes from one state to another.

The following diagram shows different changes of state, as well as which processes are the reverse of each other. Melting and freezing are the reverse processes of each other and so are evaporation (boiling) and condensation.

Answer:dew is formed on grass

Explanation:Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and there is enough moisture in the air, condensation is much greater than evaporation and the film grows into dew drops.

Answer:

Pls mark as Brainliest

Explanation:

Dew forms when the object, such as the glass, cools down to the dew point temperature. Water molecules in the air continually bombard surfaces, like blades of grass. ... If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops

As fall begins, we have lots of mornings with dew on the grass. To explain this, we start with the fact that air contains water in the gas phase, called water vapor. Dew is made of liquid water that has condensed from that water vapor.

Dew occurs when objects cool, such as when drops of liquid form on the outside of an ice-cold drink glass. Dew forms when the object, such as the glass, cools down to the dew point temperature.

Water molecules in the air continually bombard surfaces, like blades of grass. Some of the molecules stick, forming a very thin film of water. This film may not last long, as the water is also evaporating. The evaporation rate depends on the water temperature, which equals the temperature on the grass.

So condensation depends on the state of the atmosphere (primarily temperature and moisture), while evaporation depends on the temperature of the object. If the object gets cold enough, and the air contains enough moisture, condensation exceeds evaporation, and the film grows into dew drops.

Each night the weather report includes the temperature and the dew point temperature. If the two temperatures are close, dew is likely during the night. Because wind and cloudy skies keep the ground from cooling, dew also tends to form on calm nights with clear skies.
