A 60 kg girl falls off of a waterfall and loses 10 kJ of GPE. What was her height?
GPE=mgh
10³=60 x 9.8 x h
h=1.7 m
The value of her height will be 1.7 m. The formula for the gravitational potential energy is used in the given problem.
What is gravitational potential energy?Gravitational potential energy is found as the product of the mass, gravity, and height attained by the object during a fall.
The given data in the problem is;
m is the mass of a girl =60 kg
E is the gravitational potential energy= 10 kJ
h is the height traveled during free fall.
The expression for the gravitational potential energy is;
[tex]\rm \ GPE(E) = mgh \\\\ h = \frac{E}{mg} \\\\ h = \frac{10\times 10^3 }{60 \times 9.81 } \\\\ h= 1.7 \ m[/tex]
Hence her height will be 1.7 m.

- A fourth harmonic is desired by a conductor of musicians. What type of instrument could and could
not create such a harmonic. You do not need to answer in terms of the instrument name, only
whether it is open or closed ended.
What is the difference between the fourth harmonic and the nth harmonic?
The fourth harmonic has frequency f4= v/λ4= 4v/2L = 4f1, and, to generalise, The nthharmonic has frequency fn= v/λn= nv/2L = nf1. All waves in a string travel with the same speed, so these waves with different wavelengths have different frequencies as shown.
What is the weight of a box with a mass of 150 kg on Earth?
The weight is equal to 'mg' where m is the mass and the g is the gravitational constant on that certain planet
In this case, the mass is 150 kg and the gravitational constant is about 9.8.
so the weight = 150 * 9.8 = 1470 Newtons.
Hope that helped!
The weight of the box with the given mass on Earth is 1470 Newtons.
Given the data in the question;
Mass of box; [tex]m = 150kg[/tex]Weight of box; [tex]W = \ ?[/tex]WeightWeight is the force acting on the mass of a particular object or particle due to gravity. It is the gravitational force acting on an object with mass. It is measured in newtons. It is expressed as;
[tex]W = m * g[/tex]
Where m is mass of object and g is acceleration due to gravity on earth ( [tex]g = 9.8m/s^2[/tex] )
To find the weight of the box, we substitute our values into the expression above;
[tex]W = 150kg * 9.8m/s^2\\\\W = 1470kgm/s^2\\\\W = 1470N[/tex]
Therefore, the weight of the box with the given mass on Earth is 1470 Newtons.
