Question 1 of 10
1. Question

Which of the following influence the ocean currents?
1. Wind
2. Earth’s gravitational pull
3. Coriolis Force
4. Temperature
5. Salinity
Choose the correct code:
Correct
Ans c
An ocean current is a continuous, directed movement of seawater generated by the forces acting upon this flow, such as breaking waves, wind, Coriolis effects, cabbeling, temperature and salinity differences, tides caused by the gravitational pull of the Moon and the Sun.
Cabbeling is when two separate water parcels mix to form a third which sinks below both parents.
The combined water parcel is denser than the original two water parcels.
The two parent water parcels may have the same density, but they have different properties: for instance, different salinities and temperatures.

Question 8 of 10
8. Question
2 points
In the context of gravitational force and electromagnetic force, consider the following
statements:
1. While gravitational force is always attractive, electromagnetic force can be both attractive and repulsive.
2. While gravitational force is only dependent on mass, the electromagnetic force is dependent on both mass and charge.
3. While gravitational force is dependent upon the distance between two bodies, the electromagnetic force is independent of it.
Which of the statements given above is/are correct?
Correct
Ans a)
Gravitational force is always attractive while Electromagnetic force can be both attractive and repulsive. The same charges repel each other while opposite charges attract. Hence statement 1 is correct.
The electromagnetic force is not dependent upon mass. Hence statement 2 is not correct.
The gravitational force between two bodies is directly proportionate to the product of masses of the two objects and inversely proportionate to the square of the distance between them. The electromagnetic force between two bodies is directly proportionate to the product of charges of the two objects and inversely proportionate to the square of the distance between them. Hence statement 3 is not correct.

Consider the following statements with respect to Southern Lights-
1. They are also known as aurora borealis.
2. It is caused by the collision between fast moving electrons from space with the oxygen and nitrogen in Earth’s upper atmosphere.
Which of the statement(s) is/are correct?
Correct
Ans b)
The northern lights are called aurora borealis while southern lights are called aurora australis.
The typical aurora is caused by collisions between fast-moving electrons from space with the oxygen and nitrogen in Earth ‘s upper atmosphere
Incorrect
Ans b)
The northern lights are called aurora borealis while southern lights are called aurora australis.
