Are force and mass are directly proportional? Newton’s second law of motion (also known as the force law ) states that… net force is directly proportional to mass when acceleration is constant. … Is weight proportional to gravity? Mass is a measure of how much material is in an object, but weight is a measure […]
What is the importance of reference frame?
What is the importance of reference frame? Frames of Reference serve a valuable purpose, because they enable us to take in a wide variety of information, and process it based on our past experience and values. In fact, an individual’s Frame of Reference promotes life-stability and quicker decision making. What is a antonym for frame […]
What is the main drawback of seawalls?
What is the main drawback of seawalls? Hard structures partially hinder the recreational use of the coastal zone and can cause adverse ecological effects within the coastal zone. For example, when seawalls are constructed on eroding beaches, the erosion continues so that the beach in front of the seawall can become very narrow or disappear […]
What is the work required to move a charge along an equipotential?
What is the work required to move a charge along an equipotential? The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Work is needed to move a charge from one equipotential line to another. Equipotential lines are perpendicular to […]
How do you find weight with distance and work?

What are 3 factors that affect the gravity at a specific location?
What are 3 factors that affect the gravity at a specific location? Gravitational Factors of Our Eight Planets Two major factors, mass and distance, affect the strength of gravitational force on an object. What factors affect Centre of gravity? Factors affecting Stability: Relationship of line of gravity to base of support. The height of then […]

What are the 7 core values of a person-Centred approach?
What are the 7 core values of a person-Centred approach? Person-centred values Examples include: individuality, independence, privacy, partnership, choice, dignity, respect and rights. How do you promote successful aging?

What makes a fossil good for dating rocks?
What makes a fossil good for dating rocks? Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. It can only be used to date fossils younger than about 75,000 years. This makes it ideal for dating much older rocks and fossils. What is […]
