A particle has a charge of +1.5 C and moves from point A to point B , a distance of 0.

A particle has a charge of +1.5 μC and moves from pointAto pointB, a distance of 0.22 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle’s electric potential energy atAandBis EPEA – EPEB = +8.8 x 10-4J.(a)Find the magnitude of the electric force that acts on the particle.(b)Find the magnitude of the electric field that the particle experiences.

Thomas is a diabetic. While at work, he began to tremble, was somewhat disoriented, and showed signs similar to that of a drunk.

Thomas is a diabetic. While at work, he began to tremble, was somewhat disoriented, and showed signs similar to that of a drunk. One of his colleagues gave him some hard candy, which seemed to help him return to normal functions. Why did hard candy have this effect? Was giving hard candy a proper action, considering that Thomas is diabetic?

A skateboarder shoots off a ramp with a velocity of 6.5 m/s, directed at an angle of 56° above the horizontal. The end of the ramp is 1.1 m above the ground. Let the x axis be parallel to the ground, the +y direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp. (a) How high above the ground is the highest point that the skateboarder reaches? (b) When the skateboarder reaches the highest point, how far is this point horizontally from the end of the ramp?

According to the textbook, which one of the following conclusions is most true regarding factors that influence brain development?

According to the textbook, which one of the following conclusions is most true regarding factors that influence brain development?

Genetic factors have the strongest influence on brain development, particularly later in life.

Environmental factors and people’s experiences have the strongest influence on brain development in middle childhood.

Together, brain development is shaped by genetic and environmental factors throughout the life span.

Environmental factors are particularly influential in abnormal brain development.

An 82.5 g sample of a metal is heated to 98.5 Celsius and is added to 125.0 g sample of water at 21.2 Celsius. After thermal equilibrium is established, the final temperature of the mixture is 27.5 Celsius. Assuming no heat is lost to the surroundings or the calorimeter, what is the specific heat of the metal?
