Speed v = initial speed u + acceleration a x time t
v=u+at = 2 + 4*3 = 14 m/s
the two particles that are found in the center of an atom are protrons and neutrons.
Answer:
Car A is not accelerating, but car B is accelerating
Explanation:
Car A is not accelerating because , it is moving with uniform speed in a particular direction . Therefore its velocity too is not changing .
But car B is accelerating because , though its speed is uniform but its velocity is changing due to change in direction . On a circular path , direction of speed changes every moment . Therefore it has an acceleration called centripetal acceleration . Hence car B has acceleration.
Answer:
Resistivity Method
Explanation:
A disadvantage of some geophysical techniques based on magnetism is that their use in urban areas may be subject to distortion resulting from power lines and metals in the immediate vicinity. One method that can be used in such areas relies on soil moisture and the ground's resistance to electricity and is known as Resistivity.
It is usually carried out by injecting a small electrical current through the earth and measured a subtle sub-surface change in resistance over a given area.
