Answer:
x=7227
y=1678
(7227,1678)
Explanation:
Ok, check the picture I attached you, because of the problem don't give us aditional information, let's asume that the projectile is fired from an initial position x=0 and y=0. Now let's use projectile motion equations, but firs let's find the initial velocity components in x-axis and y-axis:
Now, let's find the x coordinate with this equation:
Finally asumming a gravity constant g=9.8, let's find the y coordinate with the next equation:
Answer:
= = 140 m / s
Explanation:
This is a projectile launch, in this case the components of the initial velocity are seen
Since there is no rice in the X axis, so the velocity is vx, it must be constant, at all times
= = 140 m / s
The vertical component of velocity changes due to having applied the gravity fiate
= - g t
<h2>
Answer: 0.884 g/mL</h2><h2>
</h2>
Explanation:
Density = Mass ÷ Volume
∴ the density of the liquid = 30.943 g ÷ 35.0 mL
= 0.884 g/mL
Answer: c) the sun is the most massive object; gravitational attraction is related to mass.
Explanation:
Gravitational pull exists between any two objects having mass.
where symbols have their usual meaning.
All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.
Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
