<h3><u>Answer</u>;</h3>
= 0.6
<h3><u>Explanation</u>;</h3>
Using Pythagoras theorrem
Base² + height ² = Hypotenuse²
Thus;
Base² = 15² - 12²
= 81
Base = √81 = 9
But; cosine = adjacent/hypotenuse
Hence; cos θ = 9/15
= 0.6
Answer: The apple’s energy is converted to kinetic energy as it falls. When it hits the ground, the kinetic energy is transformed into heat energy.
Explanation:
The weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.
<h3>What is weight?</h3>
The weight of an object is the force acting on the object due to gravity.
Weight, W = mg
where;
- m is the mass of the object
- g is acceleration due to gravity, 9.8 m/s²
<h3>Weight of object with a mass of 8 kg</h3>
W = mg
W = 8 kg x 9.8 m/s²
W = 78.4 N
<h3>Weight of object with a mass of 0.04 kg</h3>
W = mg
W = 0.04 kg x 9.8 m/s²
W = 0.392 N
<h3>Weight of object with a mass of 760 mg</h3>
W = mg
W = 0.76 kg x 9.8 m/s²
W = 7.45 N
Thus, the weight of object with a mass of 8 kg is 78.4 N.
The weight of object with a mass of 0.04 kg is 0.392 N.
The weight of object with a mass of 760 mg is 7.45 N.
