Answer:
1. Even though matter can be found all over the Universe, you will only find it in a few forms (states) on Earth. We cover five states of matter on the site. Each of those states is sometimes called a phase. There are many other states of matter that exist in extreme environments.
2. hot buttered popcorn, burns my tongue, smells buttery, looks yellowish-white, tastes like butter, and sounds like popping corn.
3. The water is a liquid so it has the same shape had the pan.
4.Paper clips are attracted to magnets because iron has a magnectic force.
5. The first (or smallest measurement) you would see is the hash marking millimeters, which is written as "mm". 1mm equals the thickness of a dime. The unit of measure that is most often displayed on a metric ruler would be centimeters written "cm". 10mm equals 1cm and 2.5cm is about equal to 1 inch. Centimeters are displayed for viewing like inches are, marked on the ruler in increments of 1, 2, 3, 4... and so on. Usually to 30cm which is slightly less than 12 inches.
6. Mass is used to measure the weight of an object. For example, you are measuring the mass of your body when you step on to a scale. In the metric system of measurement, the most common units of mass are the gram and kilogram.
Explanation:
Hi there!
This collision is an example of an inelastic collision since kinetic energy is lost from the collision.
We can represent this using the conservation of momentum formula:
m1v1 + m2v1 = m1vf + m2vf
Where:
m1 = blue ball
m2 = green ball
We know that the final velocity of the blue ball is 0, so:
m1v1 + m2v1 = m2vf
Rearrange to solve for the speed of the green ball:
(m1v1 + m2v1)/m2 = vf
Plug in given values:
((0.15 · 3) + (0.15 · 2)) / 0.15 = 5 m/s
Answer:
In standard GR, nothing exists at the center of a black hole. The center of a black hole is a singularity, and because GR fails at that point it is simply removed from the manifold. That means that the singularity is not part of spacetime.
To answer your question more realistically, we believe that GR is an approximate theory that fails well before you reach the center. Unfortunately, we have no good alternative theory with which to answer the question in the region where GR fails. We simply don’t have any data from that regime and it is very hard to formulate a good theory without data. So there very well could be time at the center, but we simply don’t have a good way to even guess.
Answer:
gravitational potential energy of 10 kg mass is 122.625 J
Explanation:
Gravitational Potential energy gain is given as
here we know that
m = 10 kg
h = 1.25 m
now from above formula we have
So gravitational potential energy of 10 kg mass is 122.625 J
<span>Since youc oncetrate all your force directly towards the moment arm it means that you push it at an angle of your force is directed to the left or the right and I bet that it must be 90</span> degrees to the bar. Obviuosly, if you are about to push it you will do it straight up but not in a zig zag way. In other words, it should be perpendicular to the arm because the<span> torque can be produced only if force is applied at a constant index (90).
Hope that helps! Regards.</span>
