Get out if the car
Explanation:
Get out of the car because the car could explode by over eclectic power
Answer:
a
Explanation:
The most reasonable conclusion of the above phenomenon is that water is a poor conductor of heat. Basically water is an insulator. The heat from surface to the bottom of the beaker will take a lot of time. Moreover, no convection current is formed so, heat might not even reach the bottom surface. Hydrogen bonding also play a vital role in determining the thermal properties of water.
hence option A is correct
For free fall motion the displacement can be found by graphically as well as by kinematics equation
Here acceleration of object is constant as it fall due to gravity so we can use

here if body starts with zero initial speed then we can say

here we need to find the displacement from t = 0 to t = 6s
so we can say


so the displacement will be 176.4 m
in order to find the displacement from the graph of velocity and time we need to find the area under the graph for given time interval that will also give us same displacement for given period of time.
