Answer:
a ball hanging from a tall pole
Explanation:
work is force times a distance in the direction of the force. The ball just hanging there has no motion, so is associated with no work. Work was probably done in the hanging process, but none after.
Answer:
12 m
Explanation:
The object is in uniformly accelerated motion, so the distance covered can be found using the following suvat equation:
where
s is the distance
u is the initial velocity
t is the time
a is the acceleration
For this problem,
and
u = 0, since we are considering the first second of motion
So, substituting t = 1 s, we find
Answer:
3 Objects that carry instruments into the stratosphere to measure atmospheric conditions
Explanation:
Weather balloons are objects that carries instruments into the stratosphere to measure atmospheric conditions.
They are very important weather measuring device that helps meteorologists in their fore casts.
These balloons are specially designed for high altitudes. They carry very sensitive devices that are very useful in collecting information about temperature, precipitation, pressure e.t.c
