Answer:
The acceleration increases because the mass decreases.
Explanation:
From Newton's second law, force equals mass times acceleration.
F = ma
Solving for acceleration:
a = F / m
F is constant. As the fuel runs out, m decreases. Therefore, a increases.
Two parallel plates having charges of equal magnitude but opposite sign are separated by 11.0 cm. Each plate has a surface charge density of 49.0 nC/m2. A proton is released from rest at the positive plate.
(a) Determine the magnitude of the electric field between the plates from the charge density.
b) Determine the potential difference between the plates.
Answer:
a
The Electric Field between the two plate is
b
The potential difference between the plate is V =
Explanation:
From the we are given that
The separation between the plate is
The surface charge density is
Generally Electric field between the plate is mathematically given as
Note that is the permitivity of free space and its value is
Now substituting values we have
Generally Potential difference between the plate is mathematically given as
Where E is the electric field which is
Substituting value we have
V =
Answer: 50 Pa
Explanation:
Pressure = Force/Area
Pressure = N/m^2
Pressure = 1250/25
Pressure = 50
Pressure = 50 Pa

The reason behind the barking of the group of neighborhood dogs could be <u>Territorial/Protective</u> or <u>Alarm/Fear</u>.
What is bark or barking?
Dogs are known for making the most prevalent barking noises. Wolves, coyotes, foxes, seals, and barking owls are a few other creatures that make this sounds. The most typical onomatopoeia for this sound in English, particularly for large dogs, is "woof." The word "bark" can also be used to describe the sound made by numerous canids. A bark is a brief vocalization, as per the researchers at the University of Massachusetts Amherst.
Territorial/Protective: When a person or another animal enters their perceived area, your dog may bark excessively, depending on the breed. The barking frequently gets louder as the threat draws closer. When your dog barks in this manner, he will appear vigilant and sometimes even hostile.
Alarm/Fear: Some dogs will bark in alarm or fear at any sound or item that draws their attention or alarmed them. It's not just in their home country where this can occur. When they are afraid, their tails will be tucked and their ears will be pulled back.
