Answer:

this is because as the altitude increases the number of air molecules decreases

Answer:

pressure=height × density×acc due to gravity

so

pressire is directly proportional to height hence it decreses with decrease in height

here air column height is measured upside down so decreases witn increment

Compare and contrast carbon to its isotopes: what is different about them and what is the same?

A hockey puck slides off the edge of a horizontal platform with an initial velocity of 28.0 m/shorizontally in a city where the
kozerog [31]

Answer:

θ = 12.60°

Explanation:

In order to calculate the angle below the horizontal for the velocity of the hockey puck, you need to calculate both x and y component of the velocity of the puck, and also you need to use the following formula:

\theta=tan^{-1}(\frac{v_y}{v_x})       (1)

θ: angle below he horizontal

vy: y component of the velocity just after the puck hits the ground

vx: x component of the velocity

The x component of the velocity is constant in the complete trajectory and is calculated by using the following formula:

v_x=v_o

vo: initial velocity = 28.0 m/s

The y component is calculated with the following equation:

v_y^2=v_{oy}^2+2gy         (2)

voy: vertical component of the initial velocity = 0m/s

g: gravitational acceleration = 9.8 m/s^2

y: height

You solve the equation (2) for vy and replace the values of the parameters:

v_y=\sqrt{2gy}=\sqrt{2(9.8m/s^2)(2.00m)}=6.26\frac{m}{s}

Finally, you use the equation (1) to find the angle:

\theta=tan^{-1}(\frac{6.26m/s}{28.0m/s})=12.60\°

The angle below the horizontal is 12.60°

How long does it take (in minutes) for light to reach mercury from the sun, a distance of 6.02 × 107 km?
Ksju [112]
Light travels at a speed of:
c=3 \cdot 10^8 m/s
The distance between Mercury and Sun is S=6.02 \cdot 10^7 km=6.02 \cdot 10^{10} m, so the time it takes is
t= \frac{S}{c}= \frac{6.02 \cdot 10^{10} m}{3 \cdot 10^8 m/s}  =200.7 s
if we want to convert this into minutes, keeping in mind that 1 min = 60 seconds, we should divide this value by 60:
t= \frac{200.7 s}{60 s/min}=3.34 min
