In our Solar System, Jupiter is the largest planet we have. it has the surface area of 23.71 billion mi^2. it beats all the other planets in both mass and volume.
Answer:
66 rpm
Explanation:
The period of oscillation is given by
where T is time period of oscillation which is given as 0.35 s, k s spring constant and m is the mass of the object attached to the spring.
Also, net force is given by
Net force=
where 
is the elongation, L is original length, 
is the angular velocity
Substituting the equation of 
into the above we obtain
Answer:
Option D.
A fan is turned from high speed to low speed.
Explanation:
It is important to note that air is also a fluid.
In a system, static pressure of air increases with the speed of rotation of the fan. This is because when the speed of the fan is increased, the force with which it is pushing the air molecules is increased. Since pressure is a relationship between force and area, the pressure of the air molecules will be increased.
Conversely, when the speed of the fan is reduced, the priming force on the air molecules will be reduced, hence the pressure of the air will drop.
This makes option D the correct option
Explanation:
Farmers ' overuse of fertilizers and pesticides to improve crop yields is harmful to the environment and people's health. The use of fertilizers and pesticides has contributed to climate, water, and soil pollution problems. The nitrous oxide (N2O) formed by microbial activity on inorganic soil fertilizers allows ozone layer layer to deplete, and serves as a barrier against damaging UV rays emanating from the light.
Fertilizers that are added to the soil are discharged to rivers and lakes by rainwater which causes water pollution. The trend of marine bodies nitrogen accumulation is known as eutrophication, which deteriorates the quality of the water contributing to fish death.
