Explanation:
temperature can cause change of state of a substance and change of state is a physical change. A physical change simply put is a change that isn't permanent...a change that can be reversed. the change of state of a substance is a physical change because addition of heat or a rise in temperature makes a solid melt and the removal of heat turns it back to solid
Answer: Average atomic mass of titanium on that planet is 46.52
Explanation:
Mass of isotope Ti-46 = 45.95263
% abundance of isotope Ti-46 = 77.600 % =
Mass of isotope Ti- 48= 47.94795
% abundance of isotope Ti-48 = 16.100%=
Mass of isotope Ti- 50 = 49.94479
% abundance of isotope Ti-50 = 6.300%=
Formula used for average atomic mass of an element :
Average atomic mass of titanium on that planet is 46.52
Answer:
Because Bricks don't reflect. but mirrors reflect due to their lustre nature.
Explanation:
The apparent velocity is B) 48 m/s north
Explanation:
Here we have a problem of relativity of velocities.
In fact, the train is travelling north at a speed of
where this velocity is measured with respect to the ground.
At the same time, a passenger on the train is walking towards the rear (so, south) at a velocity of
where this velocity is measured with respect to the train, which is in motion in the opposite direction.
Therefore, the apparent velocity of the passenger with respect to an observer standing on the ground is:
And the direction is north, since this number is positive.

If E = 1/2 * m * v^2
v = (2E/m)^1/2
so the larger the mass, the higher the velocity hence taylor is moving faster
