Answer:
As the Earth revolves about the sun, different sky is visible during time of the year. We have winter constellations and summer constellations. But some constellations appear through out the year like Ursa Minor are the ones which lie close to the poles. The Earth rotates about the axis passing through North and south pole. The axis always points towards North. Thus, the constellations near the Poles would be visible throughout the year.
distance : time = 20 km : 1/2 hour = 40 km/hour

on independence day, there was a bicycle race organized in a neighborhood. an observer took notes on the progress of one participant, named agni. who finally won the race... the collected data is shown in " graph of agni's bicycle track " as shown below
Answer:
Explanation:
When a person is being tailgated by another vehicle there's a risk of accident, due to the difference of speeds. When someone is being tailgated by another vehicle, it's because they vehicle doesn't work, cannot move by itself, so one vehicle impulse another.
To avoid any accident, the vehicle that's being tailgated must apply breaks often and slowly to try to maintain the same constant distance and speed than the other vehicle. This constant distance is what avoid accidents.
Therefore, the right answer is D.
Answer:
Your answer here is D
Explanation:
Slowly pressing your breaks will help ensure you are not hit by the other car. If they hit you its their fault. Hope this helps :)!
Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
Convection currents are responsible for powering the movement of tectonic plates.
