Answer:

SOLUTION: Alex swim at an average speed of 45 meters per seconds how far does he swim in 1 minutes and 24 seconds. 1 minute and 24 seconds is 84 seconds. If he swims 45 meters every second and he swims for 84 seconds, that means he swims: 45 * 84 = 3780 meters in 1 minute and 24 seconds.

Explanation:

You multiply 45 by 84 and that is equal to 3,780.

Answer: Evaporation happens by heat being transferred to the pot, then the pot transfering the heat to the water, which caused the water to vibrate more, eventually turning it into water vapor, which is how evaporation happens on the stove.

The graph below shows the variation with distance r from the nucleus of the square of the wave function, Ψ^2, of a hydrogen atom
Ludmilka [50]

The region a represents the distance of the electron from the nucleus.

According to the wave mechanical model of the atom, the probability of finding an electron within a given volume element (representing the atom) is the square of the wave function psi.

Since a is the region in space where there is the greatest probability of finding the electron in the atom, it follows that distance of the electron form the atom is always a.

An experimenter using a gas thermometer found the pressure at the triple point of water (0.01°C) to be 4.80 × 10⁴ Pa and the pre
irakobra [83]

Answer:

T = -282.33^o C

Explanation:

As we know that the relation between temperature and pressure is a linear relation

so we have

P - P_o = \frac{P_1 - P_o}{T_1 - T_o} (T - T_o)

here we know that

P_1 = 6.50 \times 10^4

P_o = 4.80 \times 10^4

T_1 = 100^o C

T_o = 0.01^o C

now we will have

P - 4.80 \times 10^4 = \frac{(6.50 - 4.80)\times 10^4}{100 - 0.01}(T - 0.01)

P = 4.80 \times 10^4 + 170.02(T - 0.01)

now if P = 0

then we will have

0 = 4.80 \times 10^4 + 170.02(T - 0.01)

T = -282.33^o C
