Answer:
Option D: More than 90
Explanation:
Thickness probably depends on temperature. The higher the temperature, the more aliens we expect to be thin.
Kinetic energy can be passed from one object to another when objects collide,
Answer: True

The amplitude is 0.8 cm. The wavelength is 2.0 cm.
Answer:
a) 
= 692 N
b) 
= 932 N
Explanation:
a)
According to newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it. When there is no net force force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions.
∝ a
= ma
= ma
Given data:
= 800 N
Mass = m = 90 kg
acceleration = a = 1.2 m/s²
= ?
800 - = (90)(1.2)
= 692 N
b)
According to newton's second law of motion,
∝ a
= ma
= ma
Given data:
If we assume the same friction and acceleration between player's feet and ground as calculated in part a
= 692 N
acceleration = a = 1.2 m/s²
We take the equal mass to the total mass of both the players because when the winning player push losing player backward, he exert force on the ground not only due to his mass but also due to the mass of losing player.
Mass = M = m₁ + m₂ = 110 kg + 90 kg
= 200 kg
= ?
- 692 N = (200)(1.2)
= 692 + 240
= 932 N
The two properties of the leaf that allow it to be affected by air resistance include its distance from the ground and its mass.
<h3>What is mass?</h3>
Mass is a scalar quantity that measures the inertia of a given body and/or object, which represent one of the most important characteristics of the matter.
This measurement (mass) may affect the flight of an object because mass inertia is associated with gravity and does not allow its movement.
In conclusion, the two properties of the leaf that allow it to be affected by air resistance include its distance from the ground and its mass.
