She would weigh less than 50 pounds. everything is super light on the moon. remember that.
It was thought that no one had studied further in the works of JJ Thomson and John Dalton at their time because there was no sufficient technology to conduct their works. However, their theory was eventually revised when Neils Bohr had theorised the modern atomic structure we know today.
Answer:
The absolute pressure of air inside the tank is 164.7 psi.
Explanation:
Given that,
Atmospheric pressure = 14.7 Psi
Gauge pressure = 150 psi
We need to calculate the absolute pressure of air inside the tank
Using formula of absolute pressure

Where,
= gauge pressure
=atmospheric pressure
Put the value into the formula


Hence, The absolute pressure of air inside the tank is 164.7 psi.
Answer: copper
Explanation: when a spoon is placed in a hot coffee, the coffee will cool off based on the concept of heat transfer.
The coffee is at a higher temperature compared to the spoon, hence there is conduction of heat by the spoon from the coffee.
Heat is now transfered from the coffee to the spoon, the rate of heat transfer ( for this case coffee to spoon) is dependent on some properties but for this case, the thermal conductivity is of the most important.
A material of high thermal conductivity have a very fast rate of heat transfer and a material of low thermal conductivity have a slow rate of heat transfer.
Below is the value of thermal conductivity for copper, aluminum, iron and glass.
Copper (385 w/m.K)
Aluminum (205 W/m.K)
Iron (79.5 W/m.K)
Glass (0.8 W/m.K)
It can been seen that copper has the highest value for thermal conductivity which implies that it will conduct heat faster compared to others thus cooling the coffee faster.
