The reason why the reaction takes place faster when the
temperature is higher is that the collision of particles of the object
increases. In order to have a faster reaction, you would need the particles of
the object to get excited and increase its collision to other particles. This
can be achieved through increasing the temperature.
Answer:
The average speed of the tourist is 88.89 km/h
Explanation:
Given;
distance of travel, d = 320 km
time of travel, t = 3.6 h
Average speed is given as;
average speed = distance / time
average speed = 320 km / 3.6 h
average speed = 88.89 km/ h
Therefore, the average speed of the tourist is 88.89 km/h
Answer:
44 m/s^2
Explanation:
Force, F = 7.95 N
mass, m = 181 g = 0.181 kg
By use of Newton's second law
F = m x a
a = F / m = 7.95 / 0.181 = 44 m/s^2
Thus, the acceleration of the hockey puck is 44 m/s^2.
