First step is to convert the lb to kg as follows:
1 lb = 0.45 kg
Therefore, 150 lb = 150 x 0.45 = 67.5 kg
Avogadro's number = 6.02 x 10^23
Mass of Avogadro's number of people = 6.02 x 10^23 x 67.5
= 4.0635 x 10^25 kg
R = V/I = 9 / 0.3
R = <span>30 ohms.</span>
Answer:
Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Explanation:
By moving object creates kinematic energy, that is true. In object itself small particles are moving and creating kinetic energy as well. Part of that kinetic energy created by moving of particles in object is transformed to heat that can be measured by thermometer.
Same thing is that when you run or exercise your body temperature is raising(because of moving ).
When you sit your body does not raise temperature.
High frequency = D, short wavelength
True
Explanation:
It is correct to say that the salinity of the oceans has been relatively constant throughout geologic time because salt is removed at the same rate it has been added.
Salinity is the amount of dissolved salt found in the ocean. It is the degree of saltiness of the ocean.
- The rate at which salt has been added into the ocean over the years through geologic time has been very constant.
- Most salts in the ocean comes from land.
- Also the rate it has been removed is fairly constant.
- The salinity of ocean has once been used to date the age of the earth.
