### Answered by answersmine:

-- We know that 345.8 g of that is just the weight of the flask.

So the weight of the liquid alone is (703.55 - 345.8) .

-- The question told us that the volume of the liquid is 225 mL .

-- The density of the liquid is

(its weight)

divided by

(its volume) .

You know the weight and you know the volume, so

you can easily find the density.

### What is the minimum speed with which he’d need to run off the edge of the cliff to make it safely to the far side of the river? the answer was 6 m/s the world-record time for the 100 m dash is approximately 10 s. given this, is it reasonable to expect brady to be able to run fast enough to achieve brady's leap? a.yes, the obtained speed is less than the world-record. b.yes, the obtained speed is almost equal to the world-record. c.no, the obtained speed is greater than the world-record. d.no, the obtained speed is almost equal to the world-record.

**The answer is**

**A. Yes, the obtained speed is less than the world record**

**The explanation:**

when the obtained speed is 6 m /s

and the world record speed = distance / time = 100 m / 10 s = 10 m/s

So, Yes, the obtained speed is less than the world record

Not only is it less, its also a reasonable average speed for a somewhat athletic person. Therefore, the leap is entirely possible.

-Samuel Brady gained his lasting notoriety for his leap over the Cuyahoga River around 1780 in what is now Kent, Ohio. After following a band of Indians into the Ohio country, a failed ambush attempt resulted in the band chasing Brady near the Cuyahoga River. To avoid capture, Brady leaped across a 22-foot (6.7 m) wide gorge of the river (which was widened considerably in the 1830s for construction of the Pennsylvania and Ohio Canal) and fled to a nearby lake where he hid in the water under a fallen tree using a reed for air.

Calculate the acceleration. 2. A car accelerates from rest (zero speed) up to a speed of 30 m/s in 12 seconds. Calculate the acceleration. 3. A cyclist in the Tour de France accelerates down a hill from 22 m/s to a speed of 37 m/s. This acceleration takes him 2 seconds. Calculate the acceleration. 4. A rocket launching in the Ukraine accelerates upwards from rest to a speed of 12 km/s in 8 seconds. Calculate the acceleration. 5. A cyclist accelerates from 0 m/s to 8 m/s in 3 seconds. What is his acceleration ? Is this acceleration higher than that of a car which accelerates from 0 to 30 m/s in 8 seconds? 6. A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. Find the car’s average acceleration. 7. A lizard accelerates from 2 m/s to 10 m/s in 4 seconds. What is the lizard’s average acceleration? 8. If a Ferrari, with an initial velocity of 10 m/s, accelerates at a rate of 50 m/s2 for 3 seconds, what will its final velocity be?

a=14 m/s / 2s

a=7 m/s^2

2. a=(v-v0)/t

a=(30 m/s - 0 m/s) / 12 s

a=2.5 m/s^2

3. a=(v-v0)/t

a=(37 m/s - 22 m/s) / 2 s

a= 7.5 m/s^2

4. a=(v-v0)/t

a=(12 km/s - 0 km/s)/8 s

a=1.5 km/s^2

etc

### A superhero flies 149 m from the top of a tall building at an angle of 25 ◦ below the horizontal. What is the horizontal component of the superhero’s displacement? Answer in units of m.

we can use cosine function to find it

there cosine 25= x/ 149m

x= 149*cosine 25

x= 135.039 m

### Just for fun, a person jumps from rest from the top of a tall cliff overlooking a lake. in falling through a distance h, she acquires a certain speed v. assuming free-fall conditions, how much farther must she fall in order to acquire a speed of 2v? express your answer in terms of h. b. would the answer to part a. be different if this event were to occur on another planet where the acceleration due to gravity had a value other than 9.80 m/s2? explain.

v = a*t

This simply means that after 1 second we will have some speed and if we double time, speed will double as well.

But, relation time-traveled distance isn't linear. Traveled distance we calculate:

s = 1/2*a*t^2 we can say that h=s

so if we double time, traveled distance will increase 4 times because of square relation between time and traveled distance.

New traveled distance (h2) will be: h2=4*h

b) Because distance depends on gravity acceleration in free fall h2 will certainly change but the relation h2=4*h will remain the same.

### Which question about dogs could be answered through scientific investigation? How loving a pet is an Irish terrier? How fast does an Australian terrier grow? Which type of dog gets along the best with cats? Which breed of dog is the cutest to children?

**Answer: How fast does an Australian terrier grow? **

Scientific investigation refers to the systematic way in which the scientists or researchers attempts to find out the reasons of the natural scientific processes. A scientific investigation involves a detailed research plan, that includes a hypothesis and methodology, to answer questions related to natural scientific processes. It involves the process of choosing the independent and dependent variables. Independent variables are those which can be changed or manipulated in an experiment. Dependent variable cannot be changed in an experiment. It is affected by the changes that occur in the independent variable.

How fast does an Australian terrier grow? is a question about dogs that could be answered through scientific investigation because growth can become a dependent variable, which can be affected by the independent variables like food, water, habits and others. Therefore, by determining the relation between the dependent variable (growth) with the independent variable(s), a scientific question can be answered.
