Answer:
The tension in the string is quadrupled i.e. increased by a factor of 4.
Explanation:
The tension in the string is the centripetal force. This force is given by

m is the mass, v is the velocity and r is the radius.
It follows that
, provided m and r are constant.
When v is doubled, the new force,
, is

Hence, the tension in the string is quadrupled.
Answer:

Explanation:
Information we have:
velocities:
initial velocity:
(starts from rest)
final velocity: 
time:
Since we need the answer in
, we nees to convert the speed to meters per second:

We find the acceleration with the following formula:

substituting the known values:

the acceleration is 10.07
What does a physical map show?
the names of countries, states, and cities
the history of an area
the geographical features of an area
the rest stops and restaurants in an area
300 miles / 6 hours = 50 miles per hour
Answer:
This is because spirit has a lower boiling point when compared to water
Explanation:
spirit has a lower boiling point when compared to water which means it has the capacity to pull more heat from your hand and also it can do this very fast. This is why our hand feels colder.
