Explanation:
T=1/f
So if frequency increases the period will decrease
<span>Answer:
6- for an object to accelerate, Newton's law #2 tells us there must be a force acting on it. F=ma the effect of a force is to accelerate the mass .
It cannot be 1, because the force must be centripetal to move the object in a circle. it can't be 2 because if an object is accelerating the velocity cannot be constant as it is moving faster. It can't be 3 because a stationary object has a net force of 0. 4 has nothing to do with the question. 5- no force is needed for uniform motion. 7- that is impossible.</span>
Answer:
The cell theory
Explanation:
The explanation of the relationship between the building blocks of life based on the evidence gathered by scientists from studying these building blocks is called <u>the cell theory.</u>
Many scientists study the building blocks. One of the earliest scientists to study these blocks gave them the name 'cells'. Thereafter, several other scientists studied different aspects of the cell and, eventually, the cell theory was propounded. There are three aspects to the theory:
- <em>All living organisms are made up of cells.</em>
- <em>The cell is the basic unit of life.</em>
- <em>Cells arose from preexisting cells by cell division.</em>
Answer:
The law of conservation of energy can be seen in these everyday examples of energy transference: Water can produce electricity. Water falls from the sky, converting potential energy to kinetic energy. ... The cue ball loses energy because the energy it had has been transferred to the 8 ball, so the cue ball slows down.
Answer:
Explanation:
(1) I= 1.5W/240V =6.25mA
(2) Energy= (1.5J/s)×(2×60×60 s)=10.8 KJ
