Answer 1

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.

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.

A baseball is thrown at 90 mph from east to west over a distance of 60 ft. What is
true of the ball's motion?
Its speed is 90 mph to the west.
Its acceleration is 30 mph.
Its velocity is 90 mph to the west.
Its acceleration is 150 mph.

Answers

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.

What is acceleration?

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.

Which characteristics belong to Whittaker’s classification system? Select two options.

a.three domains
b.six domains
c.two kingdoms
d.five kingdoms
e.five levels
f.seven levels
g.eight levels

Answers

Answer:

Five kingdoms & Seven levels

Explanation:

Robert H. Whittaker proposed five kingdom classical system for living organisms in 1969. These were: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Animalia, and Kingdom Plantae. His work was the improvement of earlier work conducted by Carl Linnaeus who proposed three kingdom classification system (Animalia, Plantae, and Protista).

Whittaker's system further categorized each kingdom to seven levels. These were: Kingdom → Phylum  →  Class  →   Order  →   Family →   Genus  →   Species. This categorization was based on similarities in organisms at different levels.

PS: The scientific name of each organism is the combination of genus and family name.
