Select the correct answer. A controlled manufacturing process involves raising the temperature of an object by a fixed amount. Which sentence relates the material-
dependent properties of the object to the amount of heat the process uses?
ОА.
The higher the specific heat of the object, the less heat the process requires.
ОВ. The higher the specific heat of the object, the more heat the process requires.
OC. The higher the conductivity of the object, the less heat the process requires.
OD
The higher the conductivity of the object, the more heat the process requires.
ОЕ.
The higher the thermal expansion coefficient of the object, the less heat the process requires.

What object a collides with object b and bounces back its final momentum is?

Which of the following are guidelines to follow for obtaining accurate observations

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.
