Answer:
Because the different waves will feel like to bounce off to different directions, and different items will do different actions.
Answer:
yes
Explanation:
when we throw a ball upwards, it will eventually come back to us because of force.
<span>The correct answer is option (d) i.e. When you return to Earth after a space mission, you will be aged slightly less than the person who remained on Earth.</span>
<span> The exact age difference depends on the details of the journey. This can be explained by the time dilation concept of Relativity.</span>
Answer: hi your question is incomplete attached below is the complete question
answer :
magnitude of acceleration : | a | = g = 9.81 m/s^2
direction : a = - g j
Explanation:
Neglecting Air resistance
magnitude of acceleration :
| a | = g = 9.81 m/s^2
Direction of acceleration
a = - g j ( given that the direction of acceleration is against the acceleration due to gravity i.e. in the opposite direction )
Answer:
74.55Hp
Explanation:
Hello! To solve this problem we must do the following 3 steps.
1. Find the ideal power using the equation to find the power W = mgV
W=mgV
where
M=mass of elevator=1700kg
g=gravity=9.81m/S^2
V=speed=3m/S
W=(1700kg)(9.81m/S^2)(3m/s)=50031W
2.
Now as the problem indicates that 10% of energy is lost in the mechanical system, we divide the power found in the previous step by 90%
3.
finally we convert units from W to hp.
the minimum output power rating in HP of the motor that meets the requirement is 74.55Hp
