Multiple choice physics motion and measurement physical quantities units - definitions and systems physical quantities like mass and weight

Knot is a measure of:

  1. The speed of ship

  2. The curvature of spherical objects

  3. Solar radiation

  4. Intensity of earthquake shock.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Knot is a measure of the speed of ship. The term knot dates from the 17th century, when sailors measured the speed of their ship by using a device called a "common log".

Hence, option A is correct.

Multiple choice physics sound: production of sound oscillation - amplitude, time period and frequency of oscillation time period, frequency and amplitude of sound oscillatory and periodic motion

Which one of the following will take place when a watch based on oscillating spring is taken to a deep mine?

  1. It will indicate the same time on earth

  2. It will become fast

  3. It will become slow

  4. It will stop working
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A watch based on an oscillating spring (like a balance wheel watch) has a period T = 2*pi*sqrt(m/k). This period depends only on the mass and the spring constant, neither of which changes with gravity or depth. Thus, it keeps the same time.

Multiple choice commercial studies striving for a better environment unequal distribution of resources protecting our environment rules are for everyone

Diastrophism is connected with

  1. Eruption of volcanoes

  2. Origin of earthquakes

  3. Rising of mountains

  4. Movement of crustal plates.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Diastrophism refers to the large-scale deformation of the Earth's crust, which includes processes like the folding and faulting that lead to the formation of mountains.

Multiple choice evs - i the earth and its living world introduction to the spheres of the earth origin of universe introduction to natural resources

The factors which relate to form and behaviour of the Earth's surface are called as

  1. Edaphic

  2. Topographic

  3. Climatic

  4. Biotic
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Topography is a field of geoscience and planetary science comprising the study of surface shape and features of the Earth and other observable astronomical objects including planets, moons, and asteroids. 

Edaphic qualities characterize the soil, including drainage, texture, or chemical properties, such as pH. 
Biotic components are the living things, that shape an ecosystem. 
A biotic factor is any living component, that affects another organism.

Multiple choice evs - i the earth and its living world introduction to the spheres of the earth origin of universe introduction to natural resources

Lithosphere is divided into 

  1. Outer core

  2. Inner core

  3. Upper most solid mantle

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The lithosphere is defined as the rigid outer layer of the Earth, consisting of the crust and the uppermost solid part of the mantle. It is distinct from the deeper, more fluid layers like the core.

Multiple choice evs - i the earth and its living world introduction to the spheres of the earth origin of universe introduction to natural resources

Which of the following is the type of lithosphere?

  1. Oceanic

  2. Continental

  3. Asthenosphere

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The lithosphere is referred to the solid part of the Earth. This is the part which includes the crust and the upper mantle. There are two types of the lithosphere. The oceanic lithosphere is the part which is comprised of the oceans. The continental lithosphere is the part which is comprised of the continental crust. The continental part comprises of a more thick layer.

Thus, the correct answer is option D.
