Ans: C) Solid

Explanation: We will look into different states

A) Liquid : In liquid state molecules are not very tightly bound to each other. So, they have no fixed shape . They take the shape of container in which they are kept.

B) Gas : In gaseous state molecules are very loosely bound so they have very less intermolecular forces so they have much more freedom of movement.So, it will be also not correct.

D) Plasma : In Plasma state approximately equal amount of positive or negative charges are there, although its a type of hot ionized gaseous state but but due its different properties then other gases it is considered the 'fourth' state. And it also can't maintain it's definite shape and volume.So we will eliminate that also.

C) Solid : Finally we are left with solid state. Here molecules are tightly bound to each other . So, it doesn't change its shape and volume when kept in different container.

So 'Solid' state is the correct choice.

Hope it helps!!!

If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning

s2008m [1.1K]

Answer:

If transpiration didn't take place water would still be able to enter the roots of a plant

Explanation:

transpiration is the process of water leaving from living organisms to the atmosphere, therefore, if transpiration didn't occur the water would not transpire to the atmosphere and would remain in the root but water absorption would not change because it is a biological need for the living organism as such

How does the amount of precipitation affect the amount of weathering ?

4vir4ik [10]

Answer: Rainfall and temperature can affect the rate in which rocks weather. High temperatures = more rainfall increasing the rate of chemical weathering. Rocks in tropical regions exposed to a lot of rainfall and hot temperatures weather faster than similar rocks in cold, dry climates.

explain why a high-speed collision between two cars would cause more damage than a low-speed collision between the same two cars

9966 [12]

The force equation can easily prove this. F=ma. This states that the force on an object is equal to mass times acceleration. If the mass stays the same and the velocity of the cars increases than that means there is a larger force. This is because in both cases the cars are stopping in almost an instant and the times of the crashes are theoretically identical. Acceleration is the change in velocity over time. If the velocity is higher with the same amount of time than that means there is a higher acceleration. If you plug a higher acceleration into the force equation then you wind up with a higher force and in turn a more damaging collision.

Assuming there are no accidents or delays, the distance that a car travels down the interstate

Ganezh [65]

Explanation:

The distance that a car travels down the interstate can be calculated with the following formula:

Distance = Speed x Time

(A) Speed of the car, v = 70 miles per hour = 31.29 m/s

Time, d = 6 hours = 21600 s

Distance = Speed x Time

D = 31.29 m/s × 21600 s

D = 675864 meters

$D=6.75\times 10^5\ m$

(b) Time, d = 10 hours = 36000 s

Distance = Speed x Time

D = 31.29 m/s × 36000 s

D = 1126440 meters

$D=1.12\times 10^6\ m$

(c) Time, d = 15 hours = 54000 s

Distance = Speed x Time

D = 31.29 m/s × 54000 s

D = 1689660 meters

$D=1.68\times 10^6\ m$

Hence, this is the required solution.

An object, experiencing no friction, keeps moving at a constant speed. What can we say about the net force on the object?

sleet_krkn [62]

Answer:

Explanation:

Let's look at a mathematical representation of this. The equation for tis is just a souped up version of Newton's 2nd Law:

F - f = ma. It an object is moving at a constant speed, the acceleration of that object is 0. That changes this equation to

F = f which states that the applied Force equals the frictional force, choice a.
