Weather balloons are :

3. Objects that carry instruments into the stratosphere to measure atmospheric conditions

Explanation:

Weather balloon is a balloon that is filled with hydrogen or helium gas. It has a life of approx. 2 hours. It move very slowly by air force up to a distance of 125 miles away from it's starting point and to a height of over 20 miles.

Weather balloons are made up of latex or neoprene, which a synthetic rubber. Once the balloon bursts, it comes down to ground by the help of a parachute attached to it.

Weather balloons are also called sounding balloons.

The instruments that are carried up by weather balloon send back information on atmospheric conditions by aid of radiosonde.

Radiosonde is a small, expendable, measuring device that transmit information through radio. They measure temperature, atmospheric pressure, humidity and wind direction.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )
