The three-toed sloth is the slowest moving land mammal. On the ground, the sloth moves at an average speed of 0.037 m/s, conside

rably slower m/s? than the giant tortoise, which walks at 0.076 m/s. – After 12 minutes of walking, how much further would the tortoise have gone relative to the sloth

Answer:

tortoise distance w.r.t sloth is 28.08 m further

Explanation:

given data

average speed v1 = 0.037 m/s

walking speed v2 = 0.076 m/s

time t = 12 min = 720 seconds

to find out

how much tortoise have gone wrt sloth

solution

we find here first tortoise walk that is

distance d1 = v2 × t

distance d1 =  0.076  × 720

distance d1 = 54.72 m

and sloth walk distance

distance d2 = v1 × t

distance d2 = 0.037 × 720

distance d2 = 26.64 m

and so

tortoise distance w.r.t sloth = d1 - d2

tortoise distance w.r.t sloth = 54.72 - 26.64 = 28.08

tortoise distance w.r.t sloth is 28.08 m further

When you have two materials with the same index of refraction, it means that
gavmur [86]

Answer:

When you have two materials with the same index of refraction, it means that if they are touched by a ray of light it won't have a chance, and its form would prevail.

Explanation:

The reason behind this is that in the first place. When light passes through an object of certain refraction it is modified from its natural state, allowing it to change in color to the human eye or many other effects in other perceptive elements. However, when the same light passes through two objects with the same refraction due to their physical characteristics, it doesn't change because once it comes out of the first one it will suffer the same effect from the last one. For it to change the refraction would have to be higher or lower. Then it would be modified. The reason is because the dimensions are not modified. Because at some point the ray of light has to come out of the first one to enter the second one.

Find by means of a vector diagram the resultant of two forces of 7N and 3N acting at right angle to one another​
melisa1 [442]

Answer:

Image result for Find by means of a vector diagram the resultant of two forces of 7N and 3N acting at right angle to one another​

The resultant of two forces of 7N and 3N acting at a right angle to one another is √58 N. Explanation: Let the magnitude of the force of 7N be denoted as “F₁” on the x-axis and the magnitude of the force of 3N be denoted as “F₂” on the y-axis.Oct 22, 2019

Your car is stalled in the middle of a large patch of ice (assumed to be frictionless). You have a friend that has thrown a rope
Gnoma [55]

Answer:

The time depends on the distance that they have to travel

x(t) = \frac{0.3846t^{2} }{2}

Explanation:

The only horizontal force exerts over the car and you, it is the force that your friend is applied

Newton's Second Law of Motion defines the relationship between acceleration, force, and mass, thus

\sum{F} = ma

        550 = 1430a

            a = 0.3846 m/s2

             

The car and you have a motion under constant acceleration, then theirs position to a time-based is:

x(t) = x_{0} + v_{0}t +\frac{at^{2} }{2}

By the initial conditions

x(t) = \frac{at^{2} }{2}

x(t) = \frac{0.3846t^{2} }{2}

The time depends on the distance that they have to travel

What quantity does this graph of a train's motion represent? Describe the train's motion
Lapatulllka [165]

Answer:

This graph shows the distance moved by the train with respect to time

Between t = 3 to t = 5 the train is at rest

Since this graph shows the distance covered by the train so it is a scalar quantity

Explanation:

Here from the graph we can see the distance covered by the train with respect to time

So here from the slope of this graph we can find the speed of the train

Also from t = 3 to t = 5 we can see that slope of the graph is zero

So here n this time interval there is no motion or it is at rest

Now since we know that this is distance vs time graph so it is a scalar quantity showing in this graph
