Explanation:
initial velocity U = 20m/s
Final velocity V = 35m/s
time = 15.0 secs
change in velocity = 35 - 15
= 20m/s
acceleration a = change in velocity/time V/t
a = (35-20)/15
a= 15/15
Hence, your acceleration is 1m/s^2
Answer:
TRUE
Explanation:
Balance forces are usually defined as the two distinct force that acts on an object but in opposite directions. These two acting forces are equal in size or magnitude. When this type of force is applied on any object, it signifies that the object is stationary or it is moving at a constant speed and in the same direction.
This force is comprised of two most important properties namely the strength and direction. When any of the two forces is higher then it result in the motion of the object.
Thus, the above given statement is TRUE.
Answer:
Decelerating
Explanation:
One arrow is moving it forward but the other arrow is using more force to move it backwards causing it to have a reduction in speed.
A pure substance is a substance that contains only one type of atom or molecule. Homogeneous mixture is commonly referred to solution as there is uniform distribution all over the mixture while in a heterogeneous mixture consists of different phases or substances that are visible.
A compound is substance containing two or more elements that are chemically bound together. Therefore, coleslaw (a salad containing finely shredded cabbages and carrots and a creamy dressing) is a heterogeneous mixture.
