Explanation:
Below is an attachment containing the solution.
Answer:
D. 5880 Joules
Explanation:
When the diver is at the highest point it has the maximum potential energy and his kinetic energy is zero due to zero velocity. As the diver jumps and accelerates during the downward motion his kinetic energy increases with the increase in speed. While the gravitational potential energy of the diver decreases due to a decrease in the height of the diver. According to the law of conservation of energy the potential energy of the diver is being converted into its kinetic energy during the downward motion. But the total mechanical energy of the diver remains constant which is equal to the sum of gravitational energy and the kinetic energy of the diver at any point.
Therefore the correct option is:
<u>D. 5880 Joules</u>
Answer:
3.53 amps
Explanation:
Given data
Power= 60W
Voltage= 17V
The expression relating current, power, and voltage is
P= IV
substitute
60= I*17
I= 60/17
I= 3.53 amps
Hence the current that flows is 3.53 amps
Answer:
Solid materials that do not possess an orderly arrangement of atoms are called glasses (mineraloids).
Explanation:
A Mineraloid is a natural, inorganic, amorphous (lacking "defined chemical composition") solid body that does not exhibit crystallinity. It exhibits characteristics similar to those of minerals, but does not have the "ordered atomic structure" necessary to meet the definition of a mineral.
Glasses or colloids have a totally random structure on an atomic scale. They are amorphous and get the honorary name of mineraloid.
