Jenny's acceleration was negative during the intervals of time when her speed was decreasing.
That's really all we can tell, because you really haven't given us any information except her name.
Negative acceleration refers to times when Jenny was slowing down in her motion. Exact intervals cannot be given without further information on her motion timeline or graphical representation.
The periods during which Jenny was negatively accelerating would be the time intervals during her motion when her speed was decreasing. In a physics context, negative acceleration (or deceleration) means that the object (in this case, Jenny) is slowing down. For instance, if Jenny was running and began to slow down, the period from when she began slowing to when she stopped would be an interval of negative acceleration. However, without specific timelines or a graphical description of Jenny's motion, it's impossible to determine the exact intervals of negative acceleration.

100° Cshe can expect once the water begins to boil.
Option: B
Explanation:
The boiling point for water at 1 pressure atmosphere of sea level is 212 ° F or 100 ° C. That value isn't a fixed. Water's boiling point is dependent on the ambient pressure, which varies based on elevation. At a lower temperature, water boils as one gains altitude like getting higher on a hill, and boils at a higher temperature if one increases the atmospheric pressure of returning to or below sea level.
It also relies upon the water's purity. Water containing contaminants like salted water boils at a level higher than pure water. This effect is called acceleration of the boiling point and is one of the material's colligative features.
Answer:
option b) 100°
Explanation:
Answer:
B) rain
Explanation:
The barometer is a device that is used to measure atmospheric pressure and, consequently, the height at which someone rises, as well as to approximately predict atmospheric changes. Thus, a rising barometer indicates an increase in air pressure, whereas a falling barometer indicates a decrease in air pressure.
In environments with low atmospheric pressure and, therefore, heat, the heated air tends to rise and, when reaching higher altitudes, condenses, forms clouds and precipitates. In this situation, the barometric pressure drops very, very quickly, indicating that a rain is coming.
Answer:
B
Explanation:
You would have rain. You would have clouds, precipitation, and strong winds.
C) Steel wheels increase friction, thus making it easier to move the load.
D) Steel wheels reduce friction, thus requiring less force to move the load.
Answer:
The solar cells transfer light energy to thermal energy.
When the battery is being charged up, chemical energy is transferred to electrical energy.
The motor is designed to transfer potential energy to kinetic energy.
