Answer:
x₂ / x₁ = √2
Explanation:
To solve this exercise we can use the projectile launch ratios, let's find the time it takes for the second book to reach the ground
y = y₀ + t - ½ g t²
as the book is thrown horizontally v_{oy} = 0, when it reaches the ground its height is zero y= 0
0 = y₀ - ½ g t²
t =
t = \sqrt{ \frac{2 \ 2h}{ g} }
with this time we calculate the horizontal distance traveled
x = v₀ t
x₂ = v₀
now let's calculate the time it takes him to get to the floor when he leaves from the first floor
t =\sqrt{ \frac{2y_o}{ g} }
the horizontal distance traveled is
x₁ = v₀
therefore the difference in distance between the two runs is
Δx = x₂-x₁
Δx = v₀ \sqrt{ \frac{4h}{g} } - v₀ \sqrt{ \frac{2h}{g} }
Δx = v₀ \sqrt{ \frac{2h}{g} } √2
Δx =√2 x₁
the relationship between the two distances is
x₂ / x₁ = √2
<span>Na+/K+ ATPase (sodium pump) is considered to be an electrogenic pump because during every transport cycle, it transports 3 Na+ ions out of the cell and 2 K+ ions into the cell. This leads to the movement of one net positive charge out of the cell making this process electrogenic.</span>
Answer : The acceleration of the elevator is,
Explanation :
Formula used to calculate the acceleration of the elevator is:
where,
F = force = 844 M
m = mass of man = 70 kg
g = acceleration due to gravity =
a = acceleration of the elevator = ?
Now put all the given values in the above formula, we get:
Thus, the acceleration of the elevator is,
Answer: 2704 J
Given :
mass = 200 g
velocity = 5.2 m/s
kinetic energy = 1/2 mv^2
= 1/2 * 200 * (5.2)^2
100 * 27.04
2704 J
