The ball’s speed and direction at the lowest point of trajectory are; 3.1 m/s and swing to the same angle on the other side
<h3>What is the speed at the lowest point?</h3>
We will assume that all of the motion will transfer to Kinetic Energy at the lowest point. Now, the difference in height will be;
Δh = (130 – 130*cos °5) = 0.49 cm
The change in PE is;
ΔP.E = mgΔh
ΔP.E = 9.8m/s² × 0.75kg × 0.049 m
ΔP.E = 0.36015 J
Formula for kinetic energy is;
K.E = ¹/₂*m*v²
From conservation of energy;
K.E = P.E
Thus;
¹/₂* 0.075 * v² = 0.36015
v = √[(0.36015 * 2)/0.075]
v = 3.1 m/s
Thus, the pendulum will swing to the same angle on the other side.

The Label of the photomicrogram of the trachea is given in the image attached.
<h3>What is the trachea?</h3>
The trachea is known to be a kind of long tube that links the human larynx (voice box) to that of their bronchi.
Note that the bronchi is one that send air to a person's lungs and the trachea is known to be an essential part of man's respiratory system.
Hence, The Label of the photomicrogram of the trachea is given in the image attached.

Answer:
-2
Explanation:
u borrow 20 and pay back with 18. What would be left in the credit is 2. So it is therefore -2
Answer:
You would need 125 1-inch cubes
Step-by-Step Explanation:
A cube with an edge length of 5 has a volume of 125 cubic inches (5x5x5 equals 125). A cube with an edge length of 1 has a volume of 1 cubic inch (1x1x1 equals 1). Divide 125 by 1 and you will find that 125 1-inch cubes are required to create cube with an edge length of 5.
People work together, on the side of the planet that wasn't damaged, you could grow a lot more plants and stop cutting trees. This could repair the damage over a few hundred years, maybe more.
