Ask Barry Allen he’s the faster man alive
Answer:
The answer to the question is 7200
Explanation:
(a) We know that the acceleration of the car is given by :
a = change in speed / time taken
If the speed of the car is constant in a straight line, the acceleration of the car is zero because there is no change in the speed of the car.
(b) For the driver steer a car traveling at constant speed so that the magnitude of the acceleration remains constant, the driver should drive the car in the circular path. This is because, in circular path the speed of an object remains the same while its velocity changes.
Answer:
The chemist is incorrect because a catalyst increases the rate of reaction only.
Explanation:
A catalyst is a substance in the presence of which the speed of the reaction increases. It plays no role in the chemical change taking place.
Thus, if the two compounds are not chemically reacting, a catalyst wont make it happen either.
A chemical reaction occurs when atoms tend to lose or gain electrons. A catalyst has no role to play in this process.
