A resistor and a fuse are devices used to control the flow of electric current in a circuit:

**Resistor**
A resistor is a passive electrical component that regulates the flow of current. It is measured in ohms (Ω) and is used to adjust signal levels, divide voltages, or reduce current flow in a circuit.

**Fuse**
A fuse is a safety device that limits current in an electrical circuit. It consists of a wire with a low melting point that melts when excessive current flows through, breaking the circuit to prevent damage. Fuses are typically made from lead-tin alloys due to their low melting point and high resistivity.

The product of force and the time during which the force acts on a body is known as impulse. Mathematically, impulse is given by \( I = F \times t \), and it is equal to the change in the body’s momentum. This relationship is described by the impulse-momentum theorem, which states that the impulse applied to an object results in a corresponding change in its linear momentum.

When an object falls freely, it exhibits the following characteristics:

Uniform acceleration: The object’s velocity increases at a rate of 9.8 meters per second squared, starting from rest.

Decreasing potential energy: The object’s potential energy decreases as it falls.

Increasing kinetic energy: The object’s kinetic energy increases as it falls.

Conversion of energy: When the object hits the ground, its potential energy is converted into kinetic energy. The kinetic energy is then converted into heat and sound energy.

Deformation of the ground: The object can deform the ground depending on the ground’s nature and the object’s kinetic energy.

The correct answer is a typhoon. A cyclone is known by different names in different parts of the world. It is called a ‘typhoon’ in Japan and the Philippines. While they are called ‘cyclones’ in the Indian and South Pacific oceans.

The tropical region generally has a hot climate because of its location around the equator. Even in the coldest month, the temperature is generally higher than about 15°C. During hot summers, the temperature may cross 40°C.

The day-to-day condition of the atmosphere at a place with respect to temperature, humidity, rainfall, wind speed, and other factors is called the weather at that place. Weather is a short-term phenomenon that can vary from day to day, hour to hour, or even minute to minute.

The correct answer is SIMA. ​It is also known as the ‘mantle’ is the second layer of the Earth’s three concentric layers, the others two being SIAL (crust) and NIFE (core).

Ganymede is the largest satellite in the solar system. Discovered by Galileo in the year 1610, Ganymede is a satellite of Jupiter. It has a diameter of around 5260 kms making it larger than the planet Mercury.

The sector between two longitude lines is called a gore. It is a curved surface on a globe that lies between two nearby longitude lines.
