An object is thrown upward with a speed of 15 m/s on the surface of planet X where the acceleration due to gravity is 2.5 m/s2.

Alex

Answer:

12s

Explanation:

the formula is

s = u×t + 0.5×a×t²

where:

s is the displacement of the object at this time (so it's equal to 0)

u is the initial speed

t is the time you have to find

a is the acceleration due to gravity

$0 = 15 \frac{m}{s} \times t + 0.5 \times 2.5 \frac{m}{{s}^{2} } \times {t}^{2}$

$15 \frac{m}{s} \times t = 0.5 \times 2.5 \frac{m}{ {s}^{2} } \times {t}^{2}$

$15 \frac{m}{s} = 1.25 \frac{m}{{s}^{2} } \times {t}$

$t = \frac{15 \frac{m}{ {s}^{} } }{1.25 \frac{m}{ {s}^{2} } }$

$t = 12s$

Which factors affect the speed of sound? type and volume of medium temperature and type of medium volume and temperature of medi

rusak2 [61]

<h3><u>Answer;</u></h3>

temperature and type of medium

<h3><u>Explanation;</u></h3>

<em><u>The speed of sound depends on the elasticity and density of the medium through which it is traveling</u></em>. That is sound travels faster in liquids than in gases and faster in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
<em><u>The speed of sound also depends on temperature.</u></em> Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly.

Bailey walks to the pizza place for lunch. To get there, she walks 3 km East, then 8 km south, and then 3 Km East again

sveticcg [70]

Answer:

Total distance she cover = 14km

Magnitude of displacement = 10 km

Direction of her displacement is East-south

Explanation:

Given:

Distance travel (East) = 3 km

Distance travel to south = 8 km

Distance travel (East) = 3 km

Computation:

Total distance she cover = 3km+8km+3km

Total distance she cover = 14km

Magnitude of displacement = $\sqrt{(3+3)^2+(8)^2}\\$

Magnitude of displacement = 10 km

Direction of her displacement is East-south
