The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.
<h3>
What is vertical motion of a projecile?</h3>
The vertical motion of a projectile is affected by gravity and the velocity of vertical motion given by the following formula;
Vy = Vsinθ
<h3>
What is horizontal motion of a projecile?</h3>
The horizontal velocity of a projectile is given by the following formula;
Vx = Vcosθ
<h3>Direction of the motion</h3>
The direction of the motion is calculated as follows;
tanθ = Vy/Vx
Thus, the formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.

According to Newton's Second Law of Motion, the force is equal to the mass of an object multiplied by its acceleration. When you talk about gravitational force, the acceleration referred to here is the acceleration due to gravity. This is very familiar to us in physics. The acceleration due to gravity on Earth is equal to 9.81 m/s². It actually depends on the location. According to the Universal Law of Gravitation:
F = Gm₁m₂/d²
The force is a factor of the product of two masses and their distance from each other. The G is a constant called the universal gravitational constants. So, gravitational force is actually a relative force exerted by one body to another.
Going back the Second Law of Motion, we can modify the equation to:
F = mg
Since it is mentioned that the gravity on the moon is only 1/6 of the Earth, then the gravity for moon is:
g,moon = 1/6(9.81) = 1.635 m/s²
So, let's compare the weight of the object with a mass of 10 kg. The weight is actually the force due to gravity pulling you towards the center of the body.
Weight on Earth = (10 kg)(9.81 m/s²) = 98.1 N
Weight on Moon = (10 kg)(1.635 m/s²) = 16.35 N
The mass, on the other hand, is not affected by gravity. It is always constant. Therefore, the mass of the object on the moon is the same with its mass on the Earth.
Answer:0.8 meter
Explanation:
Frequency=426.7hz
Velocity=346m/s
Length =velocity ➗ frequency
Length=346 ➗ 426.7
Length =0.8
Sun emits energy(light and heat) towards the earth
Incident long-wave radiation is blocked
Visible and shortwave radiation heat the earth
Earth radiates long wave radiation
<span>Long-wave radiation is blocked and heats Earth.

<span>The correct answer is an incident ray. The ray that is reflected is always reflected at the same angle at which the incident ray hits the surface. This of course only applies if it hits a straight surface, since hitting a lense would be different as it might reflect under a different angle or it might not even reflect.</span>
