Elastic and gravitational.

Answer:

elastic and gravitational

Explanation:

Mechanical energy is the sum of the kinetic energy and potential energy of an object:

E=K+U

where

K=\frac{1}{2}mv^2

is the kinetic energy of the object (with m being the object's mass and v is the object's speed),

while U is the potential energy. Potential energy refers to the position of the object, and it can be of two types:

- Gravitational potential energy: U=mgh, where g is the gravitational acceleration and h is the height of the object above the ground

- Elastic potential energy: U=\frac{1}{2}kx^2, where k is the spring constant and x is the compression/stretching of the spring.

Therefore, the correct choice is:

elastic and gravitational

Question 7 (2 points)
DiKsa [7]
This has to do with independent and dependent variables. The independent variable is what affects the dependant variable, so the question is, does a students mark on a test affect their hours of sleep or does their hours of sleep affect their test results? Which one makes more sense? I would say the latter.

A student has a mass (including clothes and shoes) of 65.0 kg. She drinks a 12 oz. can of soda, with a nutritional energy conten
Stella [2.4K]

She can climb 0.92 m without losing weight.

<u>Explanation</u>:

Gravitational potential energy is the energy consisting of the product of mass, gravity and height.

1 cal = 4184 J

140 cal = 585760 J

Energy = 585760 J,  m = 65.0 kg = 65000 g,   Efficiency = 20 %

                                 GPE = mgh

where m represents the mass

          g represents the gravity,

           h represents the height.

                             585760 = 65000 \times 9.8 \times h

                                        h = 0.92 m.
