The slope of the line on a velocityversus time graph is equal to the acceleration of the object. If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
Answer: work is the pressure acting through the change in volume
Explanation:
In the same way that work is defined as force operating over a distance, work is the pressure acting through the change in volume. Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.
The correct answer is "True."
Further Explanation:
When a person first sees someone they are interested in they may have feelings of infatuation. When a person feels this they may believe it is love, but it is a significant level of the dopamine and norepinephrine that is being released into the brain.
After a while, when the infatuation subsides, the person may not have the same feelings as before since the levels have subsided. These substances control several emotions in the brain such as cravings for food, desires, and even a person's motivation.

Answer:
Explanation:
Given:
- mass of ice block,
- initial temperature of ice block,
- initial temperature of water,
- final temperature of mixture,
- specific heat of ice,
- specific heat of water,
- Latent heat of fusion of water,
<em>Now, assuming that there is no heat loss out of the mixture:</em>
⇒ heat absorbed by the ice = heat rejected by the water
