Short-range forecasts tends to ________ longer-range forecasts.

Physics
1 answer:
melisa1 [442]3 years ago
6 0
<span>Short-range forecasts are more accurate than longer range ones. Short term forecasts may use mathematical techniques such as moving averages and, exponential smoothing. Longer term forecasts not only use different methodologies, such as qualitative vs. quantitative, they also tend to consider different issues.</span>

Please help science final test. 6 question 22 points and I will choose brainliest.
Mama L [17]

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.

Conservation of Momentum
aksik [14]

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

Does time stop in a black hole
lbvjy [14]

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.

If Maria lifts a mass of 10kg into a table of 1.25m high. How much gpe has the mass gained
SCORPION-xisa [38]

Answer:

gravitational potential energy of 10 kg mass is 122.625 J

Explanation:

Gravitational Potential energy gain is given as

U = mgh

here we know that

m = 10 kg

h = 1.25 m

now from above formula we have

U = (10)(1.25)(9.81)

U = 122.625 J

So gravitational potential energy of 10 kg mass is 122.625 J

When you push on an object such as a wrench, a steel pry bar, or even the outer edge of a door, you produce a torque equal to th
Korvikt [17]
<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).
