    The nutritional value of dried fish is generally similar to that of fresh fish, but there can be some variations due to the drying process.

    Drying fish involves removing moisture from the flesh, which can result in a higher concentration of nutrients. As a result, certain nutrients may be more concentrated in dried fish compared to fresh fish. Dried fish is known to be a good source of high-quality protein, as well as vitamins and minerals like calcium and iron.

    However, the drying process may also lead to some nutrient losses. For example, certain vitamins, particularly water-soluble vitamins such as vitamin C and B vitamins, may undergo degradation to some extent during the drying process. Additionally, if the drying involves exposure to heat or if the dried fish is stored for a long time, the levels of omega-3 fatty acids, which are beneficial for heart health, may decrease compared to fresh fish.

    In general, dried fish still retains a significant amount of its nutritional value and can be a nutritious food option. However, the specific nutrient content may vary depending on factors like the drying method used and storage conditions.

    Newton’s law of gravitation

    Sir Isaac Newton gave his famous law of gravitation in 1687. Where he mentions, every object in the universe attracts each other towards itself. He gave the formula for determining the value of this force of attraction in his formula and also determined the direction of this force.

    Newton’s law of gravitation is-

    Every particle of the universe attracts each other towards itself. The value of this attractive force is proportional to the product of the masses of the two particles and is proportional to the square of the distance between them. This force acts along the straight line connecting the centers of mass of the two objects.

    In fact, it is because of this force that the universe exists. Because there is a gravitational force between us and the Earth, we feel the pull toward the Earth and stick to it. Even because of the gravitational force between the Moon and the Earth, the Moon is confined within the orbit of the Earth and revolves around the Earth. Again for the same reason, our earth revolves around the sun. Jupiter is protecting our earth by pulling the asteroids or objects coming from other galaxies into itself through its huge gravitational force.

  5. Asked: April 5, 2023In: Science

    What is equivalent or uniform velocity?

    Sazzad Jaman Learner
    Added an answer on April 5, 2023 at 12:16 am

    If the value and direction of an object do not change during motion, i.e. the value and direction of the velocity are balanced, then the velocity of the object is called uniform velocity.

    Deregulation in electricity generation and supplying system refers to the process of removing government regulations and controls on the production, distribution, and pricing of electricity. This allows for greater competition in the electricity market and can lead to lower prices for consumers.

    Prior to deregulation, the electricity industry was often monopolized by a few large utilities, which had significant control over the pricing and availability of electricity. Deregulation aims to create a more competitive market by allowing new entrants to generate and sell electricity, thus creating more options for consumers.

    Under deregulation, the industry is typically divided into separate components, including generation, transmission, and distribution. This allows for greater specialization and competition within each component, which can lead to more efficient and cost-effective electricity production and delivery.

    While deregulation can have benefits, it can also create challenges. For example, it may be difficult to ensure that all consumers have access to affordable and reliable electricity, and there may be concerns about the environmental impact of increased competition in electricity generation.
