Answer:
cell membrane- controls what goes in and out of a cell
cell wall- protects DNA and other organelles inside a cell
ribosomes-makes and produces proteins
Explanation:
the only difference between the two is one group is powered by battery and the other group is plugged into the wall.
Answer:
43,200 Joules
Explanation:
Kinetic energy can be found using the following formula:
where <em>m</em> is the mass in kilograms and <em>v</em> is the velocity in m/s.
We know the mass is 600 kilograms, and the car is moving at 12 meters per second. Therefore the mass is 600 kilograms and the velocity is 12 m/s.
<em>m</em>=600
<em>v</em>=12
Substitute these values into the formula.
First, evaluate the exponent: 12^2. 12^2 is the same as 12*12, which is equal to 144.
Multiply 600 and 144
Multiply 1/2 and 86,400, or divide 86,400 by 2.
Add appropriate units. Kinetic energy uses Joules, or J for units.
The kinetic energy of the car is 43,200 Joules.
The motion of particles to one side of the rest position will be the same as the motion of the other side of the rest position in a wave motion. because in a wave motion or wave function, it symmetrical. meaning the motion on the other side will be identical to the other side of the rest position
Answer:
The buoyant force is the pressure of the object being forced upward.
<em>Weight of the object affects the buoyant force</em> of the submerged object; as weight is added to the object, it will cause the object to sink. The more weight...the more it will sink.
If the weight is less than the buoyant force, it will cause the object to go up.
If the weight is the same as the buoyant force, the object will stay in the same position.
