The gravitational potential energy paper airplane have PE = 0.735J.
<h3>Equation :</h3>
To calculate the potential energy we are going to use the formula,
PE = mgh
where,
PE is gravitational potential energy
m is mass of object
g is gravitational acceleration
h is height
So, given data are :
m = 0.005Kg
g = 9.8 m/s²
h = 1.5 m
PE = ?
Now, putting the values
PE = 0.005Kg x 9.8 m/s² x 1.5 m
PE = 0.0735 J
Hence, the gravitational potential energy paper airplane have is PE = 0.0735J
<h3>Gravitational potential energy :</h3>
The potential energy that a huge item has in relation to another massive object due to gravity is known as gravitational energy or gravitational potential energy. When two objects descend toward one another, potential energy associated with the gravitational field is released.

These applications DO NOT INVOLVE harmful ionizing energy:
- MRI
- ultrasound
- laser surgery
Answer:
Explanation:
Near the earth's surface where gravity is approximately 10 m/s² downward
v = u + at
v = 5 + (-10)(1) = -5 m/s
so it has the same speed but in the opposite (downward) direction.
The cathode ray experiment showed that they were both negative and positive charges in the atom. This led him to theorize that the charges MUST be spread out evenly throughout the atom. this is the plum-pudding model
