Answer:
Approximately 
(assuming that the projectile was launched at angle of 
above the horizon.)
Explanation:
Initial vertical component of velocity:
.
The question assumed that there is no drag on this projectile. Additionally, the altitude of this projectile just before landing 
is the same as the altitude 
at which this projectile was launched: 
.
Hence, the initial vertical velocity of this projectile would be the exact opposite of the vertical velocity of this projectile right before landing. Since the initial vertical velocity is 
(upwards,) the vertical velocity right before landing would be 
(downwards.) The change in vertical velocity is:
.
Since there is no drag on this projectile, the vertical acceleration of this projectile would be 
. In other words, 
.
Hence, the time it takes to achieve a (vertical) velocity change of 
would be:
.
Hence, this projectile would be in the air for approximately .

We will use the ideal gas equation:
PV = nRT, where n is moles and equal to mass / Mr
P = mRT/MrV
P = 15.4 x 8.314 x (22.55 + 273) / 32 x 4.44
P = 266.3 kPa
Answer:
Kepler's First Law: each planet's orbit about the Sun is an ellipse. The Sun's center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.
Answer:
The angle of bend = 20°
Explanation:
Since the question describes that the angle marking is similar to the metre stick marking.
The length of the object when it begins at 0 meters on the meter rule
= 1.2 m
The length of the meter stick when it begins at 0.2 m on the meter rule
= 1.0 m
The difference in length of the object based on the markings
= 1.2 - 1.0 = 0.2 m
If the green marking is on 223°, i.e. θ₂ = 223°
and the straight marking is on 253°, i.e. θ₁ = 253°
The angle of bend = θ₁ - θ₂
The angle of bend = 253° - 223°
The angle of bend = 20°
