Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. ... In reaction, a thrusting force is produced in the opposite direction.
Explanation:
Answer:
Explanation:
If I be the intensity of original light , after first polarization , its intensity becomes I/2
After second polarization its intensity becomes I/2 X Cos²θ
where θ is the angle between the two polaroids
So I₁ = I/2 Cos²θ
I₁ / I =.5 X Cos²θ = 0.123
Cos²θ = 0.246
θ = 60 degree. Ans
Answer:D. All of the above can use the EEG for diagnostic purposes
Explanation:
An electroencephalogram is a noninvasive test to check the functioning of the brain and disorders associated with it. In this test the electrodes are attached to the scalp and the electrodes record the electrical conductivity or impulse generated by the brain.
The test is used to diagnose and detect head injuries or trauma, epilepsy, brain tumors, sleeping disorders, detect the damage of brain in comatose condition and detection of symptoms of poisons or drug intoxication.
Answer:
Explanation:
Centripetal force is the net force acting on a body which makes it move along a curved path. This force is always towards the center of curvature.
The centripetal force is given by:
F = mv² / r
where m is the mass of the body, v is the velocity of the body, r is the radius, F is the centripetal force and v²/r is the centripetal acceleration.
Given that:
The gold was heated at rates too fast for the electrons absorbing the light energy to collide with surrounding atoms and lose energy.
