The only way to do that is to reduce the
volume of the container the gas is in.
Answer: The Sun measures 1.4 million km across, while the Moon is a mere 3,474 km across. In other words, the Sun is roughly 400 times larger than the Moon. But the Sun also happens to be 400 times further away than the Moon, and this has created an amazing coincidence.
Explanation:
Answer:
The magnitude of the acceleration of the box is 2 m/s².
Explanation:
Given:
Mass of the box,
kg
Force acting towards east,
N
Frictional force acting towards west,
N
Let the acceleration be
m/s².
Now, net force acting on the box towards east is given as:

From Newton's second law of motion,

Therefore, the magnitude of the acceleration of the box is 2 m/s².
The cannon is 17.69 m above the ground level
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Height (h) =?
<h3>How to determine the time </h3>
We'll begin by calculating the time taken for the ball to land on the ground. This can be obtained as follow:
- Horizontal speed (u) = 333 m/s
- Horizontal distance (s) = 622 m
- Time (t) =?
s = ut
622 = 333 × t
Divide both sides by 333
t = 622 / 333
t = 1.9 s
<h3>How to determine the height</h3>
The height of the cannon above the ground can be obtained as illustrated below:
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 1.9 s
- Height (h) =?
h = ½gt²
h = ½ × 9.8 × 1.9²
h = 4.9 × 3.62
h = 17.69 m
