Answers
The food chain will collapse with the decreases and increases of other organisms caused by the removed organism.

A solid rubber stopper has a mass of 33.0 grams and a volume of 30.0 cm3. What is the density of rubber?
Answers
This means that a driver must maintain a distance that would take at least 2 seconds to cover, at the current speed of the car. This means that in case the car in front suddenly comes to a full stop, the driver of the car behind has 2 seconds react and hit his own brakes. A two-car length rule might be alright when driving at low speeds, but when going at high speeds (on a highway, for example), a two-car length can be covered in a fraction of a second, which means a sudden braking by the car in front would almost guarantee an accident.
Answer:
4-second following distance

Answer:The magnitude of the acceleration is
Explanation:
Final velocity of the ball falling down ,v = 33 m/s
Initial velocity of the ball ,u= o m/s
Time taken by the ball to reach the ground ,t = 3.4 seconds
Acceleration of the ball during the fall = a
Using first equation of motion:
The magnitude of the acceleration is
To work this out use this formula
acceleration = distance*velocity/distance*time

Q = m c ΔT
m = 20 g, c = 4.18 J/g°C, ΔT = 30° - 10° = 20° C
Q = 20 g · 4.18 J/g°C · 20°C = 1672 J
Answer: C ) 1700 J
Answer : The amount of heat is required is, 1672 J
Solution :
Formula used :
Q= heat gained
m= mass of the substance = 20 g
c = heat capacity of water = 4.18 J/g ° C
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get the heat required.
Q = 1672 Joules
Therefore, the amount of heat is required is, 1672 J

The pellets in a shotshell start to spread or scatter as soon as they are fired. This dispersion will increase as the pellets travel farther. Shotgun barrels feature a choke to regulate this pellet pattern. The shotgun barrel's choke is the constriction at the muzzle end.
How long is a shot string?
At 20 yards, it can be roughly 5 feet long, and at 30 yards, it can be 8 feet long. The variance is brought on by the pellets' distortion as they move along the barrel.
The full choke features the tightest shot pattern and is the tightest choke. The pellets are kept together for a longer distance thanks to this choke. It is typically used for shots that are further than 40 yards.

b. The flow of air is neither toward the warm air mass nor toward the cold air mass.
c. Air moves so rapidly upward that hurricanes form.
d. Wind stops completely.
Answers
Answer: b. The flow of air is neither toward the warm air mass nor toward the cold air mass.
A stationary front forms between two air masses. A stationary front results when the warm front or cold front air stops moving. This occurs due to the fact that warm front and cold front air masses being opposite to each other but neither of them are able to repel the other. This affects the climatic conditions of the region. The weather is often cloudy along a stationary front and also supported with fall of rain and snow especially if the air in the front is cold with low atmospheric pressure.
Therefore, along a stationary front the flow of air is neither toward the warm air mass nor toward the cold air mass.
Final answer:
A stationary front is formed when a cold air mass and a warm air mass meet, but neither is strong enough to displace the other. The air flow is generally neither towards the cold nor warm air mass, often resulting in prolonged cloudiness and precipitation
Explanation:
Along a stationary front, option b best describes what happens. Generally, stationary fronts occur when a cold air mass and a warm air mass meet, but neither is strong enough to move the other. As a result, the flow of air is typically neither toward the warm air mass nor toward the cold air mass. Instead, both air masses essentially stay where they are, often resulting in prolonged periods of cloudiness and precipitation in the area surrounding the front.
