Answer:

B: The air pressure decreases

Explanation:

Pressure at any given height in the atmosphere is the total weight of the air above a unit area at any height.

Increase in elevation leads to decrease or lesser air molecules above a given surface than a similar surface at lower levels.

Answer:

B. the air pressure decreases

Explanation:

As elevation increases, there is less overlying atmospheric pressure mass, so that atmospheric pressure decreases with increasing elevaton.

Determine the force of gravitational attraction between the Earth and the moon. Their masses are 5.98 x 1024 kg and 7.26 x 1022

monitta

Answer:

$F=1.95\times 10^{20}\ N$

Explanation:

Mass of Earth, $m_e=5.98 \times 10^{24}\ kg$

Mass of Moon, $m_m=7.26\times 10^{22}\ kg$

The distance between Earth and the Moon is, $d=384,400\ km$

We need to find the force of gravitational attraction between the Earth and the moon. The force of gravity is given by :

$F=G\dfrac{m_em_m}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{5.98 \times 10^{24}\times 7.26\times 10^{22}}{(384400 \times 10^3)^2}\\\\F=1.95\times 10^{20}\ N$

So, the required force is $1.95\times 10^{20}\ N$ .

A boy on the beach holds a spherical balloon filled with air. at 10:00am, the temperature on the beach is 20°c and the balloon h

Anon25 [30]

For idea gases, volume is directly proportional to temperature. That is, an increase in temperature leads to increase in volume and vice versa.

Therefore,
V1/T1 = V2/T2 => T2 = (V2*T1)/V1

Assuming that the balloon is spherical in shape,

V= 4/3*pi*R^3.... In the formula for calculating T2, 4/3*pi cancels out.

R1 = 30/2 15 cm; R2 = 30.5/2 = 15.25 cm; T1 = 20+273.15 =293.15 K

Therefore,

T2 = (R2^3*T1)/R1^3 = (15.25^3*293.15)/15^3 = 308.05 K = 34.9 °C
