I NEED HELP ASAP PLEASEEEE.A roller coaster ride starts with the roller coaster car being pulled to the top of the first hill wi

th a pulley system. The car is released from the top with an initial velocity close to zero, then accelerates downward. From that first hill, the roller coaster just coasts; there is no driving force, other than gravity, to keep it going. Assuming no friction, what can you say about the height of the other hills in the roller coaster ride?

I assuming they are not going to be very big just small enough for the car to get over the top and not go backwards. The coasting is all the momentum thy have to get over the hill and they don't have a lot of momentum. hope this helps ☺

if an object is thrown directly upwards remains in the air for 5.6s before it returns to its original position, how long did it
Mila [183]
Okay so an object gets thrown upwards so the half way point of the trip would be the maximum height (before it starts coming back down). if the object stays in the air for a total of 5.6s, then that is the time it takes to go up and come back down. to find the time to maximum height, half the time of the whole trip

5.6s/2 = 2.8s

If hydrogen and helium are the most abundant elements in the unoverse , then why are living organisms composed primarily of carb
Mumz [18]

Answer:

Most of materia isnt life.

Explanation:

The living organisms (life) aren't the most abundant thing in universe.

Hydrogen and helium are present in everywhere, but life isn't.

There is no reason to think because we have a lot of a thing, the life must be made for this thing.

The organic life just can exists because some mysterious properties about carbon, that is the basic foundation of life, carbon is a special element, why? We don't know, actually, it's a huge problem for science discover why the carbon can makes life be possible and other elements can't. But we know is this element that makes life possible.

So, note there isn't relation about the quantity of a material in Universe and the life constituition. In addition, look around, organic materials are very rare in Universe, Earth is one in lots of places and in most of this places there isn't sign of life.

Even in Earth the life looks abundant, in Universe it isn't, the same way in Universe the Hydrogen and Helium are abudant, in Earth isn't soo.

When atoms get more and more energy, they can ionize. What can happen to a gas as more energy is added to its atoms?
Ulleksa [173]

Answer: Option (A) is the correct answer.

Explanation:

When more and more energy is provided to a gas then its atoms move more rapidly.

This rapid and continuous movement converts the gas into hot ionized ions which have positively charged ions and negatively charged electrons.

Therefore, we can conclude that as the atoms move faster, the gas can change into a plasma.

A skiy diver, with parachute unopened, falls 625 m in 15.0s.
olganol [36]

Answer:

average velocity = 6.25m/sec

Explanation:

given data:

for unopened

height = 625 m

time  = 15 sec

for opened

height = 356 m

time =  142 sec

Unopened:

V1 = \frac{625\ m}{15\ sec} = 41.67m/sec

Opened:

V2 = \frac{356\ m}{142\ sec} = 2.51m/sec

we know that

Total Average Velocity= \frac{Total\ distance}{Total\ time}

average velocity= \frac{981\ m}{157\ sec}

average velocity = 6.25m/sec

downward direction.
