Answer:
0.775 kg-m/s
Explanation:
Convert the units to the right unit forms necessary
250 g -> 0.25 kg
11.16 km/h -> 3.1 m/s
Now use the formula:
velocity
mass /
momentum / /
\ / /
\ / /
p = mv
p = 0.25 × 3.1 = 0.775 kg-m/s
Hope this helps you!

A motor takes in electricity from a cell or power source and then uses it to move components.
Therefore the answer is (1) Electrical to Mechanical
Answer:
E = 75 J
Explanation:
First, we will calculate the total power consumed by the five lamps:
Now, the energy supply can be calculated as follows:
where,
E = Energy = ?
t = time = 5 s
Therefore,
E = (15 W)(5 s)
<u>E = 75 J</u>
1. is D. Scientific method cannot be replaced.
2. is B.
3. is B as well.
