How facts differ from theroies?

frez [133]

Answer:

Facts and theories are two different things. In the scientific method, there is a clear distinction between facts, which can be observed and/or measured, and theories, which are scientists' explanations and interpretations of the facts.

Aaron rode her bike to his house to play cards he Road for 1.6 hours at 6.5 KMH another 15 minutes at four KMH what was her aver

Kay [80]

Answer:

The average speed during the trip is 6.16 $\frac{km}{hour}$

Explanation:

Speed is a physical quantity that expresses the variation in position of an object and as a function of time. In other words, speed expresses the relationship between the space traveled by an object, the time used for it and its direction.

The speed can be calculated by the expression:

$Speed=\frac{distance}{time}$

Aaron rode his bike home for 1.6 hours at 6.5 km/h and another 15 minutes at 4 km/h. So, the distance in each of the stages can be calculated as, taking into account that 60 minutes= 1 hour:

distance1=speed*time= 6.5 $\frac{km}{h}$ *1.6 hours= 10.4 km

distance2= speed*time= 4 $\frac{km}{h}$ *15 minutes= 4 $\frac{km}{h}$ *0.25 hours= 1 km

So:

total distance= 10.4 km + 1 km= 11.4 km
total time= 1.6 hours + 0.25 hours= 1.85 hours

Then:

$Speed=\frac{11.4 km}{1.85 hours}$

$Speed=6.16\frac{km}{hour}$

<u><em>The average speed during the trip is 6.16 </em></u> $\frac{km}{hour}$ <u><em></em></u>

Calculate 9 ∙ 10-5 divided by 3 ∙ 10-9. (Box after the "10" in answer is for the exponent.).

Papessa [141]

Answer:

3 × 10⁴

Explanation:

We are given two numbers, $n_1=9\times 10^{-5}$ and $n_2=3\times 10^{-9}$

We have to divide n₁ by n₂. We know that,

$\dfrac{10^n}{10^m}=10^{n-m}$

Here, n = -5 and m = -9

So on dividing we get :

$\dfrac{9\times 10^{-5}}{3\times 10^{-9}}=3\times 10^{-5+9}=3\times 10^4$

Hence, on dividing n₁ by n₂ obtained number is 3 × 10⁴.

A 60 kg Gila monster on a merry-go-round is traveling in a circle with a radius of 3 m, rotating at a rate of 9 revolutions/minu

Yanka [14]

PART A)

mass of the monster = 60 kg

radius = 3 m

frequency = 9 rev/min = 9/60 rev/s

now we can find the angular speed as

$\omega = 2 \pi f$

$\omega = 2 \pi (9/60) = 0.94 rad/s$

now the acceleration is given by

$a_c = \omega^2 R$

$a_c = (0.94)^2(3) = 2.66 m/s^2$

PART B)

now as per Newton's law we have

$F_c = ma_c$

from above all values we have

$F_c = 60(2.66) = 159.9 N$

Part C)

now monster moves inside at radius R = 1 m

so now centripetal acceleration is given as

$a_C = \omega^2 R$

$a_C = 0.94^2(1) = 0.88 m/s^2$

now the force experience by monster

$F_C = ma_C$

$F_c = 60(0.88) = 52.8 N$
