Planes don’t have mirrors
Answer:
Mass will not change based on location, while weight will change based on gravitational pull.
Explanation:
The formula for weight is mass*gravitational pull, hence weight changes based on gravitational pull
The motion of the inferior angle of the scapula in the superior and lateral direction is called upward rotation.
<h3>What are the possible motions of the scapula?</h3>
The scapula or the shoulder blade has about six different types of motion it undergoes.
The six ways of movement of the scapula are:
- protraction,
- retraction,
- elevation,
- depression,
- upward rotation, and
- downward rotation
When the inferior angle of the scapula moves in the superior and lateral direction, the motion is called upward rotation.

Answer:
The target was higher than the cannon
Explanation:
Given that a cannon ball is launched with initial speed 56 m/s, and hits a target at speed 35 m/s.
The initial velocity must be 56 m/s, while the final velocity will be 35 m/s.
When an object is thrown upward with an initial velocity, the object continues to move upwards with decreasing in magnitude of velocity till it reaches the maximum height where the final velocity will be equal to zero.
In this question, since the final velocity is less than the initial velocity, we can conclude that the target is higher.
Therefore, the target was higher than the cannon.
We know that
• The mass of the elevator is 5000 kg.
Let's draw a free-body diagram.
As you can observe, there are just two forces involved, the weight of the elevator and the tension force. Let's use Newton's Second Law.
But, W = mg = 5000kg*9.8m/s^2 = 49,000 N, and m = 5000 kg, a = 0 (because the speed is constant).
<h2>Therefore, the tension in the cable is 49,000 N.</h2>
