Sonia O'Sullivan of Ireland set the World Record in 1994 for the Women's 1000 m race with a time of 2 minutes and 45 seconds. What was her average velocity? ill give brainliest
Answer:
Sonia O'Sullivan (born 28 November 1969) is an Irish former track and field athlete. She won a gold medal in the 5000 metres at the 1995 World Championships, and a silver medal in the 5000 metres at the 2000 Olympic Games.[1] Her 2000 m world record of 5:25.36, set in 1994 stood until 2017.[2]
O'Sullivan first came to prominence when winning the 1500 m at the 1991 Universiade, before going on to finish fourth in the 3000 m final at the 1992 Olympic Games. She then won a silver medal in the 1500 m at the 1993 World Championships. She was the favourite for the 5000 m title at the 1996 Olympic Games but dropped out of the final due to illness. As well as her 1995 World title, she won three gold medals at the European Championships, in the 3000 m (1994), 5000 m (1998) and 10,000 m (1998), and is a two-time World Cross Country Champion.
O'Sullivan won silver medals in the 5000 m and 10,000 m at the 2002 European Championships, and competed at her fourth Olympic Games in 2004. She is known for her dramatic kick, clocking 28-second final 200 m splits in some of her races.[3]
She is the one of two women (the other Tirunesh Dibaba) who won the short and long course World Cross Country title at the same championship (1998 in Marrakesh).[4]

A bus has velocity of 20 m/s towards east and another bus has velocity of 15 m/s in west direction . if they start to move from a point simultaneously, what distance do they cover in 2 minutes ? what will be their seperation ?
Help plss!!
Answer:
3.8 km
Explanation:
Eastern Side Bus
Velocity = 20m/s
Covers distance in 2 min (120sec) = 20×120 = 2400m = 2 km
Western Side Bus
Velocity = 15m/s
Covers distance in 2 min (120sec) = 15×120 = 1800m = 1.8 km
Separation Distance = 2+1.8 = 3.8 km

d. blocking the Sun's rays
Answer: A
Explanation: How large a parachute is (in other words, the parachute's surface area) affects its air resistance, or drag force. ... In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall.
Answer:
a

3. There are twice as many people in the household, but your income has also doubled. Is your new
tax liability about twice as much as when you were single, more than twice as much, or less than
twice as much? Tell whether you think this difference-or the lack of one-seems fair.
Answer:
The answer is less than twice as much.
Explanation:
When the income doubles, the personal tax liability also doubles. However, because I have more dependents on my household, I'm able to get tax reductions to take care of the dependents.
A certain light bulb consumes 200J of electrical energy per second, but only emits 25J of light energy per second. Calculate the efficiency of this bulb.
Answer:
The answer is 12.5%
Explanation:
The efficiency of a light bulb is:
Light energy comes out of the bulb / Electrical energy that was put in
= 25J / 200J = 12.5%

Contrast electron movement within conductors and insulators.
Answer:
Electrons surrounding a nucleus are attracted to the protons within it because electrons and protons have opposite charges. Electrons closest to the nucleus are attracted with such a force that they can’t escape from the atom. These electrons tend to shield the protons from electrons that are farther away because electrons have the same charge and repel each other. Electrons that are farther away have less attraction to the protons within the nucleus and are more likely to be detached from the atom.
Electrons can be transferred from atoms of one body to atoms of another body through friction. This can occur when one body is rubbed against another or when a liquid flows across a solid. In either case, one body may be given a positive charge while the other body is given a negative charge of the same magnitude. Both charges are developed at the same time. Electrons can also be transferred from one body to another when a charged body comes into contact with an uncharged body. The electrons move in the direction that will equalize the charges; thus, the uncharged body will be given the same charge as the charged body.
Free electrons move from points of negative charge to points of positive charge. When these electrons move freely from one point to another with little resistance, the material they’re traveling through is said to be a conductor. Conductors have a large number of free electrons. Insulators, on the other hand, have very few free electrons and offer great resistance to the movement of these electrons. Electric charges produced on one end of a body composed of insulating materials will most likely not spread throughout the body. In a conductor, this charge would spread throughout the entire body. Metals are generally conductors; oils, rubber, air, porcelain, and plastics are good insulators.
Lightning is produced by the rapid transfer of free electrons when one of the following conditions exist:
One part of a cloud is positively charged and a neighboring part of the same cloud is negatively charged.
A positively charged cloud comes near a negatively charged cloud.
A cloud with either a positive charge or a negative charge comes near the earth.
Explanation:
Free electrons are abundant in conductors. Conversely, insulators provide a high level of barrier to the movement of these free electrons, since they have some of them. In a body made of insulating materials, electric charges generated on one end are likely to remain localized there.
What are conductors?Electrons can move freely between particles when they are in conductors, which are substances. The charge can be transported across the whole surface of an object constructed of a conducting substance.
Because distant electrons have the same charge as these nearby ones and resist one another, these electrons usually act as a shield for protons. Further distant, electrons are less attracted to the nucleus's protons and are therefore more prone to break away from the atom.
Free electrons migrate from negatively charged to positively charged locations. The substance these electrons are passing through is referred to as a conductor when it allows them to go easily from one location to another with little resistance. Electrons are abundantly free in conductors.
A body made of insulating materials will likely not conduct electricity when it generates charges on one end. This charge would permeate the entire body of a conductor. Oils, rubber, air, porcelain, and plastics are effective insulators while metals are typically conductors.

When looking at the effect of PH on sucrase activity, what was the wavelength of light used in the spectrophotometer?
Answer:
540 nm
Explanation:
Sucrase is a digestive enzyme. It is the catalyst in the hydrolysis of sucrose into the two subunits that it is made up of namely; fructose and glucose.
Enzymes are known to function best at optimum pH. As the pH of sucrase departs from its ideal pH, its activity decreases.
The activity of sucrose is studied using a spectrophotometer of wavelength about 540nm.

Which type of mirror curves outward?
Which type of mirror always has an image that is smaller than the object?
Which type of mirror is used to focus light rays?
Which type of mirror has a flat surface?
Explanation:
1. Convex mirror is curved outward.
2. Convex mirror forms an image that is smaller than the object.
3. Concave mirror is used to focus light rays. That's why it is also known as a converging mirror.
4. Plane mirror has a flat surface. It forms the same size of the image as that of the object.
The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.
Thus, A curved mirror's surface can be convex, meaning it bulges outward, or concave, meaning it bulges inward. Since a convex mirror reflects light outward, it cannot be utilized to concentrate light.
Because the focus and center of curvature are fictitious positions inside the mirror and are therefore unreachable, convex mirrors or curved mirrors always produce a virtual image.
As a result, convex mirror images cannot be projected onto a screen. The picture is also smaller than the projected object, but it grows larger as it goes closer to the convex mirror.
Thus, The reflective surface of a convex mirror, also known as a curved mirror, bulges toward the light source.
