Answer:

The correct answer is B. You would not have to travel far to see another total eclipse .

Explanation:

it is said that the way to predict or know beforehand if there is a lunar or solar eclipse is just to know the what is called the saros which are periods of exactly 223 synodic months and the eclipses are repeated or occurred in the same location every 3 Saros cycles.

Musicians can use beats to tune their instruments. One flute is properly tuned and plays the musical note A at exactly 440 Hz. A

kodGreya [7K]

Answer:

439 Hz

Explanation:

$f_1$ = Frequency of first wave = 440 Hz

F = Beat frequency = 1 Hz

$f_2$ = Frequency of the instrument

The beat frequency is the difference of the two waves which are interacting with each other

$F=f_1-f_2\\\Rightarrow 1=440-f_2\\\Rightarrow f_2=440-1\\\Rightarrow f_2=439\ Hz$

The frequency of the instrument is 439 Hz

How does gravity and density affect weight

frozen [14]

Gravity affects weight because gravity creates weight. Objects have mass, which is defined as how much matter an object contains. Weight is defined as the pull of gravity on mass.

<span> The relation between weight and gravitational pull is such that, when on another celestial body, the difference in gravity would alter a person's weight. The Earth's moon, for example, has a gravitational field that is 0.165 times the pull on earth. A person who weighs 170 pounds on Earth would only weigh 28.05 pounds on the moon. This is why during the moon landing videos, people on earth viewed the astronauts taking large, bounding steps. With very little weight, it was easy for them to push off the ground.</span>

On a distant planet, golf is just as popular as it is on earth. A golfer tees off and drives the ball 3.70 times as far as he wo

Margarita [4]

Answer:

a)H=84.87 m

b)R=565.27 m

Explanation:

Given that

Speed of ball on earth

U=41.2 m/s

θ=31°

We know that

Maximum height in projectile motion given as

$h=\dfrac{U^2sin^2\theta }{2g}$

$h=\dfrac{41.2^2sin^231}{2\times 9.81}$

h=22.94 m

Range in projectile motion given as

$r=\dfrac{U^2sin2\theta }{g}$

$r=\dfrac{41.2^2sin62 }{g}$

r=152.77 m

Given that on distance planet ball moves 3.7 times far more as on earth.

So on the distance planet

The maximum height ,H=3.7 h

H= 3.7 x 22.94

H=84.87 m

The range on distance planet

R=3.7 r

R=3.7 x 152.77 m

R=565.27 m
