Answer:
The answer is C. More water is entering the oceans from melting sea ice than is leaving through evaporation.
Explanation:
- <u><em>A primary cause for increased mass of water entering the ocean is the calving or melting of land ice (ice sheets and glaciers)</em></u>
Ashley ran with a speed of 12 feet per second.
Speed is measured as the ratio of the distance travelled to the time it took to cover that distance.
Since speed simply has a magnitude and no direction, it is a scalar quantity.
The formula for the speed of an object/body is given as-
![S=\frac{d}{t}](https://tex.z-dn.net/?f=S%3D%5Cfrac%7Bd%7D%7Bt%7D)
where, d is the distance travelled by the body/object and t is the time taken by the body/object to cover the distance
Ashley has covered a distance of 264 feet and the time taken to cover this distance is 22 seconds.
Now, Ashley’s speed can be calculated by dividing the distance of 264 feet to the time taken by Ashley cover this distance, i.e.
![\frac{264}{22} =12](https://tex.z-dn.net/?f=%5Cfrac%7B264%7D%7B22%7D%20%3D12)
Thus, the speed with which Ashley ran was 12 feet per second.

Answer:
8 seconds
Explanation:
as per 1st equation of motion
v=u+at,
u= initial velocity, v= final velocity , t=time, a=acceleration
since it starts from rest , u=0
v=16m/s
a=2m/s^2
16=0+2t
16=2t
t=8
Answer:
Distance, S = 15m
Explanation:
Given the following data;
Mass = 4kg
Force = 10N
Initial velocity = 5m/s
Final velocity = 10m/s
To find the distance;
First of all, we would calculate the acceleration
Force = mass * acceleration
10 = 4*acceleration
Acceleration = 10/4
Acceleration = 2.5m/s²
Now to find the distance, we would use the third equation of motion.
Where;
- V represents the final velocity measured in meter per seconds.
- U represents the initial velocity measured in meter per seconds.
- a represents acceleration measured in meters per seconds square.
S represents the displacement measured in meters.
Substituting into the equation, we have;
10² = 5² + 2*2.5*S
100 = 25 + 5S
5S = 100 - 25
5S = 75
Distance, S = 75/5
Distance, S = 15m
