Why do projectiles not have horizontal acceleration? Projectiles travel with a parabolic trajectory due to the influence of gravity, There are no horizontal forces acting upon projectiles and thus no horizontal acceleration, The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical […]
What is the acceleration at the highest point of a projectile?
What is the acceleration at the highest point of a projectile? zero How do you find the horizontal component? To find the horizontal component, we multiply the magnitude of the vector by the cosine angle referenced to the horizontal. To find the vertical component, we do the same thing, but take the sine angle. What […]
How much atmospheric pressure is on the human body?
How much atmospheric pressure is on the human body? The average human body surface area is 1.73 m2 and the standard atmospheric pressure is 101,325 N/m2. Hence the total atmospheric force exerted on the average human body would be 1.73 m2 x 101,325 N/m2 = 175,300 N (approx.). What happens if you spray compressed air […]
What happens to the force when the distance is doubled?
What happens to the force when the distance is doubled? So as two objects are separated from each other, the force of gravitational attraction between them also decreases. If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of […]
What are the elements of runoff?
What are the elements of runoff? COMPONENTS OF RUNOFF: Direct rainfall over the stream:- Surface runoff or overland flow: – Subsurface flow or interflow:– Base flow, groundwater flow or Dry weather flow:- What is watershed runoff? Surface runoff is water, from rain, snowmelt, or other sources, that flows over the land surface, and is a […]
How do you find the equivalent resistance of a transformer?
How do you find the equivalent resistance of a transformer? In fig -2 shows , The secondary resistance is transferred to primary winding and secondary winding is resistance less. And the total resistance at primary winding is ( R1 + R2/K2 ) which is known as the equivalent resistance of the transformer as referred to […]
What is always true inside the eye of a hurricane?
What is always true inside the eye of a hurricane? The most recognizable feature found within a hurricane is the eye. They are found at the center and are between 20-50km in diameter. The coriolis force deflects the wind slightly away from the center, causing the wind to rotate around the center of the hurricane […]
Do plants and animals have a rough ER?
Do plants and animals have a rough ER? Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes. What is the function of RER and SER? Difference between Smooth and […]
What is the least complex level of organization of the human body?
What is the least complex level of organization of the human body? Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism. What is the lowest level of organization in the nervous system? Cells are the […]
