Answer: The correct answer is [tex]a=\omega ^{2}r[/tex].
Explanation:
In the circular motion, the speed of the body is uniform but the velocity of the body changes as the direction of the body changes in the circular motion. In the circular motion, there is only centripetal acceleration.
The acceleration of a body revolving in a circle is as follows;
[tex]a=\omega ^{2}r[/tex]
Here, [tex]\omega[/tex] is the angular velocity and r is the radius.
The direction of the centripetal acceleration is directed towards the center of the circle.
Therefore, the acceleration of a body revolving in a circle at uniform speed is [tex]a=\omega ^{2}r[/tex].

Which of the following matches a human action with its impact?
Construction of dam : Scarcity of water for animals
Use of fertilizers : Increase in population of aquatic plants
Decrease in honeybee population : Increase in plant population
Construction of roads : Improvement in quality of water in local lakes
The correct answer is A
Pretty much all the answer is saying is that if you make a dam it limits water supply which is true because it blocks water from flowing smoothly.
Most of the asteroids in the solar system circle the Sun in a large ring, which is located immediately between the orbits of and
The rocky, airless worlds known as asteroids orbit our solar but are too tiny to be referred to as planets. The main asteroid belt, a large doughnut-shaped ring between the orbits of Mars and Jupiter, is home to tens of thousands of these minor planets. Near-Earth Objects are asteroids that pass by Earth quite closely.
What are asteroids ?One of the smaller planets in the inner Solar System is an asteroid. Asteroids are stony, metallic, or ice worlds without an atmosphere, with sizes and forms ranging from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.
The bulk of asteroids that are now known orbit in the asteroid belt between Mars and Jupiter, often with orbits that are not overly elongated. Millions of smaller asteroids as well as between 1.1 and 1.9 million asteroids larger than 1 kilometer (0.6 miles) in diameter are thought to be present in the belt.
Rock fragments from the solar system's early history are dispersed in orbits around the sun. The majority of these things are planetoids or asteroids.
Thus, The rocky, airless worlds known as asteroids orbit our solar but are too tiny to be referred to as planets.

At the beach, differences in temperatures create wind which transfers heat between the land and the water. The same process is also seen in the ocean as the gulf stream carries heat from the tropics northward. Heat transfer through any intermediate fluid is known as A)condensation. B)conduction. C)convection. D)radiation.
Answer: Option (C) is the correct answer.
Explanation:
When a fluid is heated then hot material, that is, less dense will rise at the top whereas cool material, that is, more dense will sink at the bottom. This process helps in exchange of heat within the molecules and it is known as convection.
Therefore, we can conclude that heat transfer through any intermediate fluid is known as convection.

Convert the temperature 288 K to degrees Celsius
To convert 288 K to degrees Celsius, subtract 273.15 from the Kelvin temperature. Using this method, 288 K is equivalent to 14.85°C.
Explanation:The question requires converting the temperature from Kelvin to degrees Celsius. To convert temperature from Kelvin (K) to degrees Celsius (°C), you subtract 273.15 from the Kelvin temperature. The formula used is T°C = K - 273.15.
Given the temperature is 288 K, using the formula we get:
T°C = 288 K - 273.15 = 14.85°C
Therefore, the temperature of 288 Kelvin converts to 14.85°C in degrees Celsius.

Which of these is a process by which water, carbon dioxide, and energy are formed? Which of these is a process by which water, carbon dioxide, and energy are formed? A) heating of sugar B) dissolving of sugar C) oxygen reacting with sugar D) hydrogen reacting with sugar
Answer:
C) oxygen reacting with sugar (usatestprep)
Explanation:
Oxygen reacting with sugar during the process of respiration produces water, carbon dioxide, and energy.
Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, therefore the correct answer is option C.
What is solar energy?The energy emitted by the Sun as a form of thermal electromagnetic radiation is known as solar energy. This solar energy is produced by nuclear fusion in the center of the Sun. Solar energy is a form of renewable source of energy.
Thus, Oxygen reacting with sugar is a process by which water, carbon dioxide, and energy are formed, it is a type of exothermic reaction in which excess energy is produced on the product side, therefore the correct answer is option C.
