Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
Change in speed = (25 m/s) - (5 m/s) = 20 m/s
Time for the change = 20 sec
Acceleration = (20 m/s) / (20 sec)
<em>Acceleration = 1 m/s²</em>
Answer:
The number of electron in the outermost shell of a particular atom determine how the reactivity of atoms to form chemical bonds with other atoms
Explanation:
This is because the number of atoms in the outer shell will determine if the atom has to gain or loose electrons for it to bond with other atoms
Hope this helps, and if it does mark as branliest answer thx
1 watt is a RATE of using energy ... 1 Joule per second. If you use energy at the RATE of 1 watt and keep it up for 1 whole second, you've used 1 whole Joule of energy. 1 watt-second = 1 Joule .
Answer:
The value is 
Explanation:
From the question we are told that
The speed of the airplane from the north is 
The negative sign is because the direction is towards the south
The speed of the airplane from the east is 
The negative sign is because the direction is towards the west
The distance of the southbound plane from the airport is 
The distance of the westbound plane is 
Generally the distance between the plane is mathematically represented using Pythagoras theorem as
Next differentiate implicitly this equation to obtain the rate at which the distance between the planes changes
So
Here

Answer: Kinetic theory or kinetic theory of gases attempts to explain overall properties of gases, such as pressure, temperature, or volume, by considering their molecular composition and motion. The theory basically states that pressure is not caused by molecules pushing each other away, like earlier scientists thought.
