Answer:
The mass of the puck is 0.166 kg
Explanation:
It is given that,
Speed of the ice hockey puck, u = 12 m/s
Impulse delivered by the hockey stick, J = 4 kg-/s
After delivering an impulse, the puck move off in the opposite direction with the same speed, v = -12 m/s
We need to find the mass of the puck. The impulse is equal to the change in momentum i.e.
m is the mass of the puck
So, the mass of the puck is 0.166 kg. Hence, this is the required solution.

Answer:
Educational institutions can influence what psychological perspectives are taught, studied, and researched. Take, for example, behaviorism. Before the cognitive perspective re-emerged, behaviorism was the dominant perspective being taught in most universities. Personal ideology can also affect which perspective a psychologist supports, the course of research a psychologist undertakes, and also a psychologist's perception and interpretation of research findings. For example, during the dominance of behaviorism, psychologists were discouraged from studying cognitive processes. As a result, much of the research conducted had a behaviorist slant to it.
Explanation:
Answer:
999 V
Explanation:
Charge deposited on the capacitor
= current x time
= 2 x 10⁻³ A x 5 x 10⁻³
= 10⁻⁵ C
increase in volt = charge deposited / capacitance
10⁻⁵ / .1 x 10⁻⁶
= 10² V
= 100 V
voltage in the beginning = -1 V
voltage at the end
= -1 + 100
99 V .
