Answer:
Obviously the answer is Sun...
Answer:
Pressurized gas
Explanation:
When we compress the gas, the volume occupied by a gas decreases, since the volume is inversely proportional to the pressure, the compression of the gas causes an increase in Pressure. The molecules not only collide with each other but also on the walls of the container.
Compressed gases can cause fires, explosions, low-oxygen atmospheres, exposure to toxic gases and the physical danger associated with high-pressure cylinders. Special procedures for storage, use, handling and disposal are required to ensure the safety of the researchers who use these chemicals and equipment. There are also risks associated with the gas pressure and the physical weight of the cylinder. A falling gas bottle can break containers and crush your feet. The cylinder can become a missile if the cylinder valve breaks.

Explanation:
Given parameters:
Distance = 15miles north = 24140.2m
Initial velocity = 0m/s
Final velocity = 4m/s
Unknown:
Speed, velocity and acceleration = ?
Solution:
The speed is the distance divide by time. It is a scalar quantity and has no directional attribute.
Speed =
The speed of the student is 4m/s
Velocity is the displacement divided by time. It is a vector quantity which specifies the direction and magnitude;
Velocity =
The velocity of the student is 4m/s due north
Acceleration is the change in velocity with time;
To find the acceleration, we use
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance
4² = 0² + 2x a x 24140.2
a =
= 0.00033m/s²
Answer:
D.
The forces on the book are balanced because the gravity pulling down on the book is equal to the upward force applied by the table.
