Answer:
The radius of the sphere is 3.6 m.
Explanation:
Given that,
Potential of first sphere = 450 V
Radial distance = 7.2 m
If the potential of sphere =150 V
We need to calculate the radius
Using formula for potential
For 450 V
....(I)
For 150 V
....(II)
Divided equation (I) by equation (II)
Hence, The radius of the sphere is 3.6 m.
Answer:
9.52 am
Explanation:
The p-waves travel with uniform motion (constant velocity), so we can calculate the time they take to travel from the epicenter to the point where they are recorded using
where
d is the distance covered
v is the speed of the p-waves
On average, the speed of p-waves is
v = 7 km/s
Here they have to cover a distance of
d = 5600 km
So, the time they take is:
Converting into minutes,
Since they were recorded at 10.05 am, it means the earthquake occurred 13 minutes before that: so, at 9.52 am.
magnitude of the net force = mass x acceleraton
= 22 x 2.3
=50.6 N
The distance from the speaker would the sound be barely audible is 477.46km.

What is distance?</h3>
It's how far away two objects or locations are measured numerically as distance. Distance in physics or common language can refer to a physical length or an assumption based on other factors (e.g. "two counties over"). Sometimes the symbol |AB| is used to indicate how far apart two points are. "Distance from A to B" and "Distance from B to A" are typically equivalent terms. A distance function or metric in mathematics is an extension of the idea of physical distance; it defines what it means for components in a space to be "near to" or "far away" from one another. Distance is a non-numerical unit of measurement in the social sciences and psychology.
