5.5m/s

Explanation:

Given parameters:

Mass of ball = 22kg

Kinetic energy  = 334J

Unknown:

Velocity of the girl  = ?

Solution:

Kinetic energy is the energy possessed by a moving body. It is the energy due to the motion of a body.

It is mathematically expressed as;

    K.E = \frac{1}{2}  m v^{2}

 Input the values;

   334 = \frac{1}{2} x 22 x v²

       v² = \frac{334}{11}

      v² = 30.4

       v = √30.4 = 5.5m/s

Naddika [18.5K]

Answer:

Explanation:

Galileo proved the superiority of the heliocentric theory over the geocentric theory . Heliocentric theory changed the centre of universe from the earth to the sun . According to this theory , the solar system or the universe revolves around the sun .

But the present knowledge of universe considers sun as one of billions of stars present in the universe , with each star behaving as sun with its  own solar system . The universe is made of cluster of stars with each cluster having their  own centre around with they revolve . These clusters are called galaxy . Sun is a part of cluster called milky way . Sun along with other star of this galaxy revolves around the centre of its galaxy which is a super massive star .

Hence the old heliocentric theory does not fit into the present framework of universe by the scientist.

What is the pressure exerted by 0.801 mol of co2 in a 12 l container?
Svetlanka [38]
We assume that the gas is an ideal gas so we can use the relation PV=nRT. Assuming that the temperature of the system is at ambient temperature, T = 298 K. We can calculate as follows:

PV = nRT
P = nRT / V
P = (0.801 mol ) (0.08205 L-atm / mol-K) (298.15 K) / 12 L
P = 1.633 atm
