centripetal acceleration is given by formula
given that
now we have
so the ratationa frequency is given by
Answer:
1.
d
. A stream of particles
2. D. Radiowave
3. Microwaves
Answer:
cytoplasm and channel gates
Explanation:
The movement originates from the cytoplasm. This is the fluid medium through which ions are shuttle from one place to another. However, though simple as it might appear to be, the movement requires carrier proteins. The are proteins that facilitate in the movement of the ions. These proteins have specially controlled gates called channel proteins. These are regulated proteins that open and close based on hydrogen ion concentration. These proteins are able to facilitate the movement of ATP molecules.
The correct option is B.
Resonance is said to occur when one object which is vibrating at the same natural frequency of a second object forces the second object into vibrational motion. When resonance is achieved a big loud voice is usually heard. Resonance generally requires three conditions to occur:
1. An object that has a natural frequency.
2. A force that is functioning at the same frequency as the natural frequency.
3. Prevention of energy loss.
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, 
kg
Height to which the object is raised above his head, 
m
Acceleration due to gravity is, 
m/s²
We know that for a mass 
raised to a height 
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
