Answer:
Mass
Explanation:
Density is defined as mass/volume. So mass is directly proportional to the density. Therefore, if the mass changes, then the density will also change. Likewise, density will not change if the mass remains constant.
Hope this helps!
Answer: C. warm ocean air causes a dry climate
Oceanic water and wind currents affects the climatic conditions of the nearby terrestrial regions. This is because of the fact that it takes more energy to change the temperature of the water than terrestrial land or air, the temperature of the water warms up more rapidly than it is cooled upon.
The warm up water of the ocean will evaporate and the air currents blown away from the ocean will be warm and will make the climate warm and dry.
Energy remains constant is the answer you are looking for but it only applies, when no outside forces act on the object.
Answer:
Explanation:
The relationship between angular acceleration α and torque τ is given by :
Here,
is the moment of inertia. It depends on the mass and the distance from the axis of rotation.
is the angular acceleration
Hence, this is the required solution.
If the mass of the original sample of Galium-68 is 10 mg, then . . .
== After one half-life, (1/2)(10 mg) = 5 mg remain
== After the second half-life, (1/2)(5 mg) = 2.5 mg remain
== After the third half-life, (1/2)(2.5 mg) = 1.25 mg remain
It doesn't matter how long the half-life is.
