ଦିଲ୍ଲୀ ଅପେକ୍ଷା କଲିକତା ରେ troposphere ର ଉଚ୍ଚତା ?
Correct Answer
A. ଅଧିକ
Explanation
The correct answer is "ଅଧିକ" which means "higher" in English. This suggests that the troposphere in Delhi is at a higher altitude compared to Kolkata.
2.
ନିମ୍ନୋକ୍ତ କେଉଁ ସ୍ତରରେ ଉଲ୍କା ର ଘର୍ଷଣ ହୋଇଥାଏ ?
Correct Answer
C. Mesosphere
Explanation
The mesosphere is the correct answer because it is the layer of the Earth's atmosphere where meteors burn up upon entering. This layer is located above the stratosphere and below the thermosphere. It is characterized by low temperatures and contains the coldest part of the atmosphere, known as the mesopause.
3.
ସମୟ ର S.I ଏକକ କେଉଁଟି ?
Correct Answer
B. ସେକେଣ୍ଡ
Explanation
The correct answer is "ସେକେଣ୍ଡ". This is because "ସମୟ ର S.I ଏକକ" translates to "unit of time in S.I system" and "ସେକେଣ୍ଡ" is the unit of time in the S.I system.
4.
ନିମ୍ନୋକ୍ତ ମଧ୍ୟରୁ କେଉଁଟି ସବୁଜକୋଠରୀ ଗ୍ୟାସ ନୁହେଁ ?
Correct Answer
C. ଅମ୍ଳଜାନ
Explanation
The correct answer is "ଅମ୍ଳଜାନ". This is because CFC (chlorofluorocarbon) is a greenhouse gas, while "ଅଙ୍ଗାରକାମ୍ଳ" refers to a flammable gas and "ଜଳୀୟବାଷ୍ପ" refers to water vapor. Therefore, "ଅମ୍ଳଜାନ" is the only option that is a greenhouse gas.
5.
ମେରୁ ଅଂଚଳରେ ବାୟୁର ଆର୍ଦ୍ରତା ?
Correct Answer
B. ସର୍ବନିମ୍ନ
Explanation
The correct answer is "ସର୍ବନିମ୍ନ" which means "minimum" in English. This suggests that the air humidity in the region mentioned is at its lowest level.
6.
ଭୂକମ୍ପ ତରଙ୍ଗ କେଉଁ ସ୍ତରରେ ସୃଷ୍ଟି ହୋଇଥାଏ ?
Correct Answer
B. Lithosphere
Explanation
The lithosphere is the correct answer because it is the outermost layer of the Earth's surface, consisting of the crust and the uppermost part of the mantle. It is rigid and solid, and it is where tectonic plates are located. Earthquakes, including seismic waves, occur within the lithosphere. The other options, such as the asthenosphere, mesosphere, and core, are not directly involved in the creation of seismic waves during an earthquake.
7.
ଭୂକମ୍ପ ମାଧ୍ୟମରେ କଣ ସଂଚରିତ ହୋଇଥାଏ ?
Correct Answer
C. ଶକ୍ତି
Explanation
In the context of an earthquake, the correct answer is "ଶକ୍ତି" (energy). During an earthquake, energy is transferred through the earth's crust in the form of seismic waves, causing the ground to shake. The other options, such as "ତରଙ୍ଗ" (wave), "ପଦାର୍ଥର କଣିକା" (particle of matter), and "ଚାପ" (pressure), do not accurately describe the phenomenon of an earthquake.
8.
ନିମ୍ନୋକ୍ତ କେଉଁ ରାଜ୍ୟଟି ମଧ୍ୟଦେଇ କର୍କଟ କ୍ରାନ୍ତି ଯାଇନାହିଁ ?
Correct Answer
C. ମଣିପୁର
Explanation
Manipur is the correct answer because it is the only state mentioned in the options that is not located in the western part of India. The question asks for a state that does not undergo a revolution in the middle, implying that the other three states (West Bengal, Gujarat, and Tripura) experience some form of revolution or significant change in the middle. Therefore, Manipur is the only option left as the correct answer.

ଗୋଟିଏ ସ୍ଥାନ ର ସମୟ ଲଣ୍ଡନ ର ସମୟଠାରୁ 2.30 ମିନିଟ ପଛୁଆ ।ଭାରତରେ ମଧ୍ୟରାତ୍ରୀ ହୋଇଥିବା ବେଳେ ସେଇ ସ୍ଥାନର ସମୟ ?
Correct Answer
C. 4PM
Explanation
The time difference between London and Gotiye is 2 hours and 30 minutes. So, if it is 4 PM in London, then it would be 1:30 PM in Gotiye. As the question asks for the time in India, we need to consider the time in Gotiye and add 2 hours and 30 minutes to it. Therefore, the correct answer is 4 PM.
10.
ସମତ୍ୱରାନ୍ବିତ ଗତିରେ ଗତି କରୁଥିବା ବସ୍ତୁର ?
Correct Answer
A. ପରିବେଗ 0
Explanation
In this question, the correct answer is "ପରିବେଗ 0" which means "velocity 0" in English. The question asks about the object that will have motion in a state of equilibrium. In physics, equilibrium refers to a state where the net force acting on an object is zero. In this case, if the velocity is zero, it means that the object is not moving and hence, the net force acting on it is zero. Therefore, an object with zero velocity will have motion in a state of equilibrium.

ସମପରିବେଗରେ ଗତି କରୁଥିବା ବସ୍ତୁର ତ୍ୱରଣ ?
Correct Answer
C. ତ୍ୱରଣ 0
Explanation
The question is asking about the acceleration of a moving object. The options given are "paribega 0" (velocity 0), "bega 0" (speed 0), "twaran 0" (acceleration 0), and "AOTA" (All of the above). The correct answer is "twaran 0" because if the acceleration of an object is 0, it means that the object is not changing its velocity over time, and therefore its speed and velocity will also be 0.
12.
ଦୁଇଟି ପୃଷ୍ଠ ମଧ୍ୟରେ କାର୍ଯ୍ୟ କରୁଥିବା ବଳ ଟି ?
Correct Answer
C. ଘର୍ଷଣ ବଳ
Explanation
The correct answer is "ଘର୍ଷଣ ବଳ" because it is the only option that relates to the action of working between two surfaces. "ମାନ୍ସପେଶୀୟ" means muscular, "ମାଧ୍ୟକର୍ଷଣ" means average, and "ଘର୍ଷଣ" means friction. Only "ଘର୍ଷଣ ବଳ" is related to the concept of working or acting between two surfaces.
13.
ବସ୍ତୁତ୍ୱ × ମାଧ୍ୟାକର୍ଷଣ ଜନିତ ତ୍ୱରଣ = ?
Correct Answer
C. ଓଜନ
Explanation
The given question is asking for the product of mass and acceleration, which is the formula for force according to Newton's second law of motion. Therefore, the correct answer is "ଓଜନ" which means "mass" in English.

ସମପରିବେଗରେ ଗତି କରୁଥିବା ବସ୍ତୁର ସଂବେଗ କାହା ଦ୍ୱାରା ପ୍ରଭାବିତ ହେବାର ଆଶଙ୍କା ରହିଛି ?
Correct Answer
E. NOTA
