Answer is C. Convection
Answer:
The power rating of the blender is 300 W.
Explanation:
To find the power of an object, you need to divided the work by the time. Thus, we would divide the work, 1,500, by the time, 5 seconds. This gives you the answer, 300 W.
The velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.
To find the final velocity of the stroller after it has traveled a certain distance while accelerating, one can calculate it using the third equation of motion:
v²-u² = 2as
The third equation of motion is one of the equations used in classical physics to describe the motion of an object with constant acceleration.
Given:
Acceleration, a = 500 m/s²
Distance, s = 6.32 m
The velocity is computed as:
v² - 0² = 2 × 500 × 6.32
v² = 6320
v = 79.5 m/s
Hence, the velocity a stroller is pushed from rest, accelerating at 500m/s is 7.5 m/s.

B. 1 m/s.
C. 1 m/s².
D. 1 m/s north.
Answer:
80 seconds
Explanation:
40/.5 is equal to 40*2 which is 80 or in another way 1 second is 2 seconds is 1 m
