Only if the temperature of both samples is the same.
When the temperature of water changes, so does its density.
That means that more or less mass takes up the same volume,
and the same volume can get heavier or lighter.
The acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².
<h3>How to calculate acceleration?</h3>
The acceleration of a moving object can be calculated using the following formula:
a = (v - u)/t
Where;
- a = acceleration (m/s²)
- v = final velocity (m/s)
- u = initial velocity (m/s)
- t = time (s)
According to this question, a car starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds.
a = (25.5 - 12.5)/5
a = 13.0/5
a = 2.6m/s²
Therefore, the acceleration of a car that starts at 12.5 m/s and reaches 25.5 m/s in 5.00 seconds is 2.6m/s².

Answer:
D bcz the slope rose the fastest
Explanation:
I DON'T WANNA BE QUESTIONED, THIS IS BECAUSE y POSITION ROSE FASTER THAN x POSITION
Answer:
BRAINLY IS NOT A DATING APP!!!!
Explanation:
The hint is "constant speed".
If there is a net force on an object, what occurs to that object? F net = m*a.... It accelerates!
So, if the desk is going at a CONSTANT speed, what does that tell you about the acceleration? There is a change in speed.
Fnet = m*a Since a = 0 Fnet = 0
Fnet = sum of the force... reflect the direction of F as the positive direction. Sum of the forces in the direction of F = 0 0 = F - friction F = friction
So, if F = 800 N, then friction = 800 N in the opposite direction.
