What is the direction of velocity of an object moving along a circular path Class 9? directed towards the centre of the circle. Is velocity a vector or a scalar? Speed is a scalar quantity – it is the rate of change in the distance travelled by an object, while velocity is a vector quantity […]
Does buoyant force increase with pressure?
Does buoyant force increase with pressure? Pressure Increases Buoyant Force Pressure therefore increases buoyant force, which is equal to the weight of the water being dispersed. Why does buoyant force change with depth? Buoyancy or buoyant force is proportional to object’s volume and density of the fluid in which the object floats. So with depth, […]
Why do I pee after I pee?
Why do I pee after I pee? After dribble happens because the bladder doesn’t empty completely while you urinate. Instead, the urine accumulates in the tube leading from your bladder. A common cause for after dribble is an enlarged prostate or weakened pelvic floor muscles. How can I make my bladder stronger? Follow these 13 […]
What will happen if the primary of a transformer is connected to DC supply?
What will happen if the primary of a transformer is connected to DC supply? If the primary of a transformer is connected to the DC supply, the primary will draw a steady current and hence produce a constant flux. Consequently, no back EMF will be produced. Can a transformer work when it is connected to […]
What is life span development approach?
What is life span development approach? The Lifespan Developmental Approach has provided an overarching framework for understanding human development from conception to death. Development across the lifespan results in changes in the interaction between biological and environmental influences that impact the allocation of resources. What are the 5 major principles of human development? The principles […]
How is temperature and humidity related?
How is temperature and humidity related? As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases. Temperature therefore directly relates to the amount of moisture the atmosphere can hold. How does atmospheric pressure affect the body? Barometric pressure is the weight of the atmosphere […]
What is independent variable in probability?
What is independent variable in probability? Two events are independent, statistically independent, or stochastically independent if the occurrence of one does not affect the probability of occurrence of the other (equivalently, does not affect the odds). Are functions of independent variables also independent? Functions of Independent Random Variables are Independent. How do you show independence? […]
Are wires live if switch is off?
Are wires live if switch is off? Normally, hot is switched. Neutral and ground are not switched. Normally, that results in a safe environment where this is nothing “live” when hot is switched off. Fixtures wired correctly so that the wires that should be hot are hot and the wires that should be neutral are […]
Can a body in free fall be in equilibrium?
Is V at dimensionally correct?
Is V at dimensionally correct? Identify the dimensions of v from the table above: Identify the dimensions of a from the table above and multiply by the dimensions of t: Therefore, v = at is dimensionally correct because we have the same dimensions on both sides. What does v2 u2 2as mean? Final velocity (v) […]
