Answers
Answer:
A. enlarged or larger than the object
B. Erect image or not-inverted
C. Virtual
Explanation:
In the given situation, the object is placed between pole and focus of a concave mirror.
So, the image will be formed on the right side of the mirror having size larger than the object; the image will be erect image which means image will appear right side up; and the image will be virtual because image is formed behind the mirror due to divergence of light rays.
Hence, the correct answers are:
"A. enlarged or larger than the object
B. Erect image or not-inverted
C. Virtual"

Using your knowledge of fluid pressure, explain why your ears hurt more and more as you dive deeper and deeper underwater.
Answers
Answer:
Ear pain is the most common complaint from scuba divers. Some divers call it "ear squeeze." As a diver goes deeper under water and the outer environment pressure increases, the pressure in the middle ear (the part behind the ear drum) is "squeezed" by the increasing pressure of the water from outside

3. Is the relationship between the gravitational force and the mass directly proportional or
inversely proportional?
Answers
Answer:
Directly Proportional
Explanation:
Gravitational force can be calculated with the equation F = g(m1 * m2)/ r^2
So if we increase mass, force will also increase because mass is in the numerator.
Preview this picture of a roller coaster. Does it make you feel safe? How does the picture reinforce the idea of roller coasters being safe as stated in the article?
Answers
Answer: The coaster tracks serve to channel this force — they control the way the coaster cars fall. ... If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt-up, gravity applies a downward force on the back of the coaster, so it decelerates.
Explanation: They may be safe though!

What are 5 violations of the rules for Ultimate Frisbee
Answers
Answer:
Violations. A violation occurs when a player violates the rules in a manner which does not result in physical contact ( e.g. throwing a pass during an approach to the goal line; illegal guarding position by the marker; not establishing a pivot foot after carrying the disc in from out-of-bounds, etc.)
The object of Ultimate Frisbee is to gain points by scoring goals. The disc may only be passed, and a goal is scored when a player successfully passes the disc to a teammate in the end zone which that team is attacking. The team with the most points at the end of the game is declared the winner.
Explanation:
Vert (Vertical) Stack – The most common offensive play in Ultimate Frisbee. The Mailman – An intense offensive tactical maneuver to guarantee a gain of at least 70% of the field. TurboDisc – Can be added to almost any play to ensure max effectiveness.
If contact occurs and the thrower drops the disc, the count stops until the thrower picks up the disc and continues with play. The defensive player will have to back up 5 yards (15 feet) to allow a free throw from the offensive player.
to start something moving, a push force must be ______ than resisting forces such a friction. what word complets the gap?
Answers
Answer:
To start something moving, a push force must be greater than resisting forces such a friction.
Explanation:
The force of resistance, for example friction, slows things down, so the push force must be greater in order to increase the speed or to start something moving.
What is the Eg, Ek, and Ediss of a skier starting at an elevation of 40m and ending at 0m elevation
Answers
Answer:
E_g = m 392 J, Ek = m 392
Explanation:
Mechanical energy is a very important concept since if the system does not have friction it remains constant
the potential energy of a system is
E_g = U = m g (y2 - i)
E_g = m 9.8 (40 -0)
E_g = m 392 J
The kinetic energy for this system assuming it started from rest
E_k = K = ½ m v2
how mechanical energy is conserved
E_g = E_k
Ek = m 392

Which statement below best describes Gregor Mendel’s conclusions about genetics based on his pea plant experiments?
A. DNA is the biomolecule of life. Its structure is a double-helix and it is the blue print for the structure and function of an organism.
B. Each parent plant transmits certain factors to its offspring. These factors combine and determine the plant’s traits.
C. When two organisms reproduce, the offspring will generally result in a blending of the parent’s traits.
D. Mendel’s experiments ended up being inconclusive. Although he saw some patterns of inheritance, he was unable to determine the “how” behind it.

daughter nuclei
C. The time it takes for all the daughter nuclei in a sarnple to become
parent nuclei
D. The time it takes for half the daughter nuclei in a sample to
become parent nuclei
Answers
Answer:
A
Explanation:
The amount of time necessary for half of anything to go through a process, such the amount of time needed for half of a radioactive substance's atoms to decay. Thus, option A is correct.
What half-life of a radioactive isotope?The period of time it takes for one-half of a radioactive isotope to decay is known as the half-life. An individual radioactive isotope's half-life is unaffected by environmental factors and is independent of the isotope's starting concentration.
Radiation emission stops after an atom achieves energy stability through radiation. A radionuclide's concentration falls over time, and its radioactivity declines. A (physical) half-life is the length of time required for radioactivity to degrade and diminish to half.
Therefore, The time it takes for half the parent nuclei in a sample to become daughter nuclei.
