Answer:
The cat will have <span>36J</span> of kinetic energy.
9* m
Explanation:
Step 1:
We are given the initial length of the Pyrex glass dish at a particular temperature and need to calculate the change in the length when the temperature changes by 120° C. The coefficient of linear expansion of Pyrex is provided.
Step 2:
Change in length = Coefficient of linear expansion * Change in temperature * Initial length
Step 3:
Coefficient of linear expansion = 3* /°C
Change in temperature = 120°C = 120 K
Initial length = 0.25 m
Step 4:
Change in length = 3* * 120 * 0.25 = 9* m
Answer:
14.8 m
Explanation:
S= ut + a
where u = initial velocity
S= (0 )(2) + (7.4)(2)
S= (7.4)(2)
S=14.8 m
