Answer:
The time is 176 seconds
Explanation:
We use the formula:
V= d/t V=velocity, d= distance, t= time
259 m/s= 45683 m/ t
t= 45683 m// 259 m/s
t= 176, 3 seg
Answer:
yes, because you guy's are moving in a car. because if you think about it, your parents are driving, but the cars moving so basically you guys would be moving.

Electric field is proportional to the charge and inversely proportional to the square of distance:
With charge 2q and distance 2r, the electric field is proportional to:
The new electric field is half of that of the original measured field.

Explanation:
If two negatively charged objects are brought close together, then they will repel each other. If two positively charged objects are brought close together, then they will repel each other. If a positively charged object is brought near to a negatively charged object, they will attract each other.
Answer:
258 Hz or 266 Hz
Explanation:
When two sounds of similar frequency occur at the same time, a phenomenon called "beat" occurs. The beat is an interference patter between the two sounds; the frequency of this beats (called beat frequency) is given by the difference between the frequencies of the two sounds:
where
is the beat frequency
is the frequency of the 1st sound
is the frequency of the 2nd sound
In this problem,
is the beat frequency
is the frequency of the middle C tuning fork
is the frequency of the middle C piano string
Solving for f2, we find two solutions:
