Answer:
10.13
Explanation:
take note that velocity is distance over time (
) so you do 456(distance)÷45(time)= 10.13
Answer:
The car slowing from 60 m/s to 0 m/s
Explanation:
The bird flying at 10m/s for 10 seconds will have the same speed for those 10 seconds. So we can say it doesn't have a varying speed (During those 10 seconds, we don't have any information about what happens later).
The fish moving at 2m/s for 5 minutes will have the same speed for those 5 minutes. So we can say it doesn't have a varying speed (During those 5 minutes, we don't have any information about what happens later).
The car traveling the speed limit, we know that his speed is the speed limit. It doesn't change.
The car slowing from 60 m/s to 0 m/s needs to change his speed in order to go from 60 m/s to 0 m/s. The speed will decrease progressively until the car completely stops.
Answer:
Density
Explanation:
Density is a property that will allow for a possible identification of a material. Different materials have different densities. The unit for density is g/cm^3
We use kinematic equation of motion,
Here, s is distance traveled, u is the initial velocity, t is time taken and g is acceleration due to gravity.
Given, 
.
We take, 
because stone has no initial velocity.
Therefore,
Thus, the height of cliff is approximately 61.75 m.
Number of valence electrons. A valence electron is an outer shell electron that is associated with an atom.
hope this helps x
if it did i would really appreciate brainliest! :)
