What if Earth were twice as big? If Earth’s diameter were doubled to about 16,000 miles, the planet’s mass would increase eight times, and the force of gravity on the planet would be twice as strong. Life would be: Built and proportioned differently. Can we live on the sun? But if you take a look […]
Why are the two kinds of charge called positive and negative?
Why are the two kinds of charge called positive and negative? Positively charged: electrons are removed making the object electron deficient. Negatively charged: electrons are added giving the object an excess of electrons. Who invented positive and negative charge? Benjamin Franklin How many types of charges are there? two Which element has a charge of? […]
What is mechanical energy equal to?
What is mechanical energy equal to? An object’s ability to do work is measured by its mechanical energy, or the sum the object’s kinetic energy and potential energy. Mechanical energy is due to the position or movement of an object. The formula for mechanical energy is mechanical energy = kinetic energy + potential energy. How […]
How does speed and weight affect the amount of kinetic energy?
How does speed and weight affect the amount of kinetic energy? The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. This means that an object with twice the mass and equal speed will have twice the kinetic energy while an object with […]
Which of the following stimulates the release of ADH?
Which of the following stimulates the release of ADH? ADH is normally released by the pituitary in response to sensors that detect an increase in blood osmolality (number of dissolved particles in the blood) or decrease in blood volume. The kidneys respond to ADH by conserving water and producing urine that is more concentrated. Where […]
What are 3 things that cause weathering?
What are 3 things that cause weathering? Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and […]
What is not an example of a machine?
What is not an example of a machine? Bridge is not a machine, it is a structure. A bridge is a structure built to span a physical obstacle, such as a body of water, valley, or road, without closing the way underneath. It is constructed for the purpose of providing passage over the obstacle, usually […]

What is tissue and its types?
What is tissue and its types? Tissues are groups of cells that have a similar structure and act together to perform a specific function. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. What is epidermis class 9th? Epidermis: It is the outermost protective layer of plant organs. The epidermis […]
