Hello!
Here we can use PE=mgh
So with your givens we have
Mass=17kg
PE= 350J
g=9.80m/s^2
So we have
350J = 17kg * 9.80m/s^2 * h
Now we just solve for our height! So we have
350J/(17kg*9.80m/s^2) = 2.10m is the height of the shelf. So rounded to nearest whole number, the shelf is 2meters high.
Hope this help. Any questions please just ask. Thank you so much!
Two point charges, feel a force of 1. 0 n when they are 2. 0 cm apart. if they are moved further apart to 8. 0 cm. The electric force between them will be F2 = 1/16 J
A charged particle, also called an ion, is an atom with a positive or negative charge. This happens whenever something called an ionic bond forms. Two particles that have different numbers of electrons (the smallest particle in an atom which is negative) start reacting to each other.
According to Coulomb's law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.
F1 = K q1*q2 /
1 = K q1*q2 /
F2 = K q1*q2 /
F2 = K q1*q2 /
F1 / F2 = 64 / 4
1 / F2 = 16 / 1
F2 = 1/16 J

The following is a list of the events that occur during a muscle contraction. What is the correct sequence of these events?
1. Myosin cross-bridges bind to the actin.
2. The free myosin head splits ATP.
3. Calcium ion is released from the sarcoplasmic reticulum.
4. The myosin head pivots toward the center of the sarcomere.
5. Calcium ion binds to troponin.
6. The myosin head binds an ATP molecule and detaches from the actin.
The correct answers are: Options 2,4 and, 5
