Answer:
9.81N
Explanation:
the force of attraction is given by
F=<u>GmM</u><u>/</u><u>R²</u><u> </u>
where m is mass of the body
M is mass of the earth
R is radius of the earth
G is the universal gravitational constant(6.67x10-¹¹)
hence we substitute the values in the formula.
<em> </em><em>you</em><em> </em><em>can</em><em> </em><em>ask</em><em> </em><em>questions</em>
Answer: The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measures the displacement of a liquid by a solid.
Explanation:
Volume is the amount of the space occupied by an object. Volume can be used to measure the amount of the space occupied by the solid, liquid and gas.
When the direct measurement is not possible then the indirect measurement is used by taking the small part that object to calculate the whole part of that.
The limitations of the calculated and indirect volume measurement are as follows,
The calculated volume measures the side of the cube to get the volume. An indirect measurement of volume measure the displacement of a liquid by a solid. For example, the volume of the liquid is displaced by the sponge is not equal to the volume of the sponge.
They are chemically opposite in that the reactants of one are the products of the other. One could not exist without the other to supply the materials.
You can look up the reactants and products in any Biology textbook. also <span>In Photosynthesis carbon dioxide and energy is consumed to give sugar and Oxygen. </span>
<span>while in Respiration oxygen and sugar is consumed to give energy and carbon dioxide is produced. </span>
<span>Hence the two are opposite of each other. </span>
<span>Now, since you need oxygen to respire there must be a constant supply of oxygen and plants are the source of oxygen since they produce oxygen due to photosynthesis, similarly plants need oxygen to do photosynthesis which is produced by respiration. </span>
<span>Hence they both are dependent on each other HOPE IT HELP ;D</span>
Answer:
The charged particle follows a spiral path in a magnetic field.
Explanation:
A charge immersed in a region with an electric field experiences a force that acts along the same direction of the electric field. In particular:
- The force has the same direction as the electric field if the charge is positive
- The force has the opposite direction as the electric field if the charge is negative
Therefore, a charge moving in an electric field is accelerated along the direction of the electric field.
On the other hand, a charge in motion in a region with a magnetic field experiences a force that acts perpendicular to the direction of the field. This means that a charge in motion in a magnetic field will acquire a circular motion in the plane perpendicular to the direction of the magnetic field.
As a result, if the particle has also a original motion outside this plane, its final motion will consist of:
- A uniform motion along that direction, +
- A circular motion along the plane perpendicular to the field
So, the resultant motion of the particle will be a spiral path. So the correct answer is
The charged particle follows a spiral path in a magnetic field.
It is possible to distinguish between these types of radiation by the use of an electrostatic field.
<h3>What is a radioactive source?</h3>
A radioactive source is a source that emits radiation such as alpha, beta and gamma radiation. We can be able to distinguish between these types of radiation by the use of an electrostatic field.
The gamma rays is undeflated by the field, the alpha ray is deflated to the negative part of the field while the beta rays is deflated by the positive part of the field.
