Robin Hood wishes to split an arrow already in the bull's-eye of a target 40 m away.
tamaranim1 [39]

Answer:

5.843 m

Explanation:

suppose that the arrow leave the bow with a horizontal speed , towards he bull's eye.

lets consider that horizontal motion

distance = speed * time

time = 40/ 37 = 1.081 s

arrow doesnot have a initial vertical velocity component. but it has a vertical motion due to gravity , which may cause a miss of the target.

applying motion equation

(assume g = 10 m/s²)

s=ut+\frac{1}{2}*gt^{2}  \\= 0+\frac{1}{2}*10*1.081^{2}\\= 5.843 m

Arrow misses the target by 5.843m ig the arrow us split horizontally

How do the valves do in the heart​
Rina8888 [55]

Answer:

The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.

An astronomer sees two stars in the sky. Both stars are equally far from Earth, but the first star is dimmer than the second sta
kvv77 [185]

Answer: It is smaller than the second star

Explanation: The brightness of a star depends on two factors: The distance from the Earth and size of the star. More the distance from the Earth, the star appears dimmer. And bigger the star, brighter it is.

b =\frac{L}{4\pi d^2}

Where L is the luminosity,d is the distance

Luminosity depends on the surface area of star (4\pi R^2)

Here, it is given that the two stars are at the same distance from the Earth. The first star is dimmer.  We can conclude from this that first star star must be smaller than the second star.
