4. Describe the umpire’s actions for these signals. out - time - Arms are extended above the head, palms out. This position is held until the ump is satisfied that the signal has been seen and observed. safe - Both arms are extended in front of the body, palms down. The position should be held long enough to be seen by players, managers, and other umpires. strike - The right arm and hand are moved outward from the body and at least waist high. walk - ually called vocally
5. What is a designated hitter? Right fist is clenched, arm is raised. everyplayer has to rotate to the hitter position that is the national league. in the american league there are main hitters which has to be listed on the lineup card before the game.
6. What happens when a game is tied at the end of nine innings? if its a tie at the end of nine innings they will add on 2 more innings for over time
Answer:
Explanation:
Ball
There is no signal for a called ball. Instead, simply verbalize the call, "ball". Call the ball while still down, then come up. On ball four, don't point to first base, just say "ball." If the batter doesn't head toward first base, you can simply say to him "that's four."
Strike
Signal strikes with your right hand. Use the traditional clenched fist ("pounding the door"), or signal with your hand/finger shot out to the side. On a called strike, verbalize sharply; everyone should hear. On a swinging strike do not verbalize; simply give the signal.
Safe
Extend both arms together in front of you and then give a quick, sweeping motion outward, roughly parallel to the ground, palms down. On close plays, you can also verbalize the call, "safe", or "he's safe". This helps sell a close call. You can also verbalize information to help sell an extremely close call, things like "Safe - he's under the tag", of "Safe - he pulled his foot." On obvious calls ("stadium calls") don't verbalize the call.
Out
Form a hammer with a clenched right fist and deliver a quick, sharp blow. Some degree of personal style is allowed on the out call, as long you are not distracted from seeing any continuing action. If necessary, verbalize and signal additional information to sell a close call, like "off the bag" or "on the transfer."
Fair Ball
Point the right hand toward fair territory. Never verbalize "fair ball." On a close call, to emphasize the call, stab your arm into fair territory multiple times emphatically.
Foul Ball
The signal for foul ball is the same as for "Time" or other dead ball situation: Raise both hands and call loudly "Foul." Make the call loud and sharp, so everyone hears. Note that, once verbalized, you cannot reverse a call of foul ball.
Play
Point at the pitcher with the right hand with a stabbing motion and call "Play."
You must put the ball back in play following every time the ball goes dead, whether foul ball, hit-by-pitch, called "time", or other reason. When the pitcher has the ball and is ready (he must have engaged the rubber), and the catcher is in the catcher's box and is also ready, point and call "play". Under no circumstances should you allow the pitcher to go into his windup until you have called "Play".
Time
Raise both hands and call "Time" in a loud voice. Make the call loud and sharp. It is essential that everyone on the field hear you.
Important: When any umpire calls "Time," all other umpires should echo the call by also signaling and, if there is play in progress, also verbalizing "Time."
time
(Time with a small "t"). There are occasions when time is out, but "Time" has not been called. An example is when the pitcher is ready but the batter is not yet set; in this case, the plate umpire might put up his hand as a stop sign to the pitcher, signaling him to wait. It is important to understand that when you put up a stop sign like that you have called time. So you must put the ball back in play.
Important: Be very careful with this small-"t" Time. Be certain, for example, that all continuous play has come to a stop, that runners are back to their bases, and that no sudden actions are imminent. You're in a world of hurt if you've got a hand up signaling time, just as a runner breaks and a bang-bang play develops, an overthrow occurs, a run scores, and THEN you have to get everyone's attention to bring it all back.
The count
Indicate pitch count using the left hand for balls and the right hand for strikes. On fields that do not have scoreboards, give the count frequently; always give the count on an "action" pitch (with three balls and/or two strikes). Call the count loudly, so both benches (and base coaches) can hear it clearly. Finally, don't abbreviate the count by verbalizing things like "twenty-two" for two and two, or saying "full count" when the count is three and two.
3rd strike not
caught
Give the strike sign, but do not call or signal the batter out. Instead, clear the catcher and give the safe sign.
What does relative humidity measure?
the amount of water in cirrus clouds
the amount of water that has evaporated into the air
the amount of frozen water that has condensed from the air
the amount of water vapor in the air compared to the amount the air can hold
Answer:
It is D
Explanation:
edge unit test review thing
Relative humidity measures the amount of water vapor in the air compared to the amount the air can hold at a specific temperature. The correct option is option (4).
It is a measurement of the moisture content in the air relative to its capacity to hold moisture.
The relative humidity is expressed as a percentage and indicates how close the air is to being saturated with water vapor. A higher relative humidity value means that the air contains a larger amount of water vapor compared to its capacity at that temperature.
Therefore, It is important to note that relative humidity is not a direct measure of the amount of water in specific cloud types or the amount of frozen water that has condensed from the air. The correct option is option (4).

A mover loads a 100 kg box into the back of a moving truck by
pushing it up a ramp. The ramp is 4 m long and the back of the
truck is 1.5 m high. What is the potential energy gained by the
box when it's loaded into the truck? Use g= 10 m/s2
Explanation:
Mechanical Advantage (MA)
MA=d1d2=FoutFin ; d1 is the distance of effort, d2 is the distance the object is moved
The potential energy of the box when it is loaded into the truck is the product of its mass, height of the truck and gravity. Thus potential energy of the box is 1500 J.
What is potential energy ?Potential energy of an object is the energy generated by virtue of its position. This energy is stored on the object when it is rest. When the object starts moving its potential energy starts convert to kinetic energy.
When an object is falling down, it is associated with a gravitational potential . The potential energy is related to the mass m, height of the object from the surface h and acceleration due to gravity g as follows:
p = mgh
Given the mass of the box = 100 kg
height of the back of truck = 1.5 m
g = 10 m/s²
Then p = 100 × 1.5 m × 10 m/s² = 1500 J
Therefore, the potential energy of the box is 1500 J.

Describe the relationship between wavelength, frequency, and energy in electromagnetic waves. Which waves are the most dangerous?
Iguanas need to live in a habitat that is very warm, so the pet store warms their enclosures with “basking lights” which act as an artificial sun. Describe how the three methods of thermal energy transfer may take place within the iguana’s enclosure.
(ANSWER ALL QUESTIONS PLEASE!)
Answer:
1 question- Three different things happen when light hits a surface, it can be reflected (bounce off), absorbed or transmitted (pass through). Glass reflects some light but most of the light is transmitted straight through. That's why we can see objects on the other side of a closed window. We say that glass is transparent.
2 question- All materials have what is known as an index of refraction, which is linked to how fast light can travel through the material. As light passes through air and into another clear material (such as glass), it changes speed, and light is both reflected and refracted by the glass
3 question- The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. In other words, the greater the energy, the larger the frequency and the shorter (smaller) the wavelength
4 question- The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them
5 question- Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. Conduction is the transfer of heat between substances that are in direct contact with each other. Thermal energy is transferred from hot places to cold places by convection. Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation.

Your 20-kg brother Mickey is on a see-saw. If you have a mass
of 50-kg and are 2 meters away from the center of the see-
saw, how far out would Mickey have to sit if he wants to apply
the same force onto you that you apply onto him? meters
Answer:
5
Explanation:
To apply the same force as the person, the brother have to sit at a distance of 5 m.
What is meant by torque ?
Torque is defined as the rotational analogue of force. It is the cross product of force and the displacement of the object.
Here,
Mass of the person, m₁ = 50 kg
Mass of the brother, m₂ = 20 kg
Distance of the person, d₁ = 2 m
For the see-saw to get balanced, the torque applied by the two persons each side must be equal.
τ₁ = τ₂
where τ₁ is the torque applied by the person and τ₂ is that applied by the brother.
So, F₁d₁ = F₂d₂
m₁g x d₁ = m₂g x d₂
m₁d₁ = m₂d₂
Therefore, distance of the brother,
d₂ = m₁d₁/m₂
d₂ = 50 x 2/20
d₂ = 5 m
Hence,
To apply the same force as the person, the brother have to sit at a distance of 5 m.
