Answer:
Carbon dioxide is added to atmosphere naturally when organisms respire or decompose
Or through human activities, such as the burning of fossil fuels and forests and the production of cement.
If E = 1/2 * m * v^2
v = (2E/m)^1/2
so the larger the mass, the higher the velocity hence taylor is moving faster
Psychologists study animals because they want to understand how different species think and behave, animal psychology is often simpler and easier to understand than human physiology, and it is more permissible to conduct certain types of research with animals than with humans
Answer:
a) Initial angular speed = 30 rad/s
b) Final angular speed = 70 rad/s
Explanation:
a) We have equation of motion s = ut + 0.5at²
Here s = 400 radians
t = 8 s
a = 5 rad/s²
Substituting
400 = u x 8 + 0.5 x 5 x 8²
u = 30 rad/s
Initial angular speed = 30 rad/s
b) We have equation of motion v = u + at
Here u = 30 rad/s
t = 8 s
a = 5 rad/s²
Substituting
v = 30 + 5 x 8 = 70 rad/s
Final angular speed = 70 rad/s
