Answer:
v = 0 and a = 9.8 m/s²
Explanation:
When an object reaches the highest point, its velocity is equal to 0. After reaching the highest point, it starts to decelerate. The acceleration is in the downward direction and it is equal to g i.e. 9.8 m/s².
So, the velocity and acceleration of the ball at the highest point in its path is 0 and 9.8 m/s² downward.
Hence, the correct option is (d).
It is 500000 kg in 0.5 mg
Answer:
The part of the wave is the Amplitude.
Reason: The amplitude of light waves is responsible for our perception of brightness, with larger amplitudes appearing brighter than lower amplitudes.
Explanation:
The amplitude of light waves is responsible for our perception of brightness, with larger amplitudes appearing brighter than lower amplitudes.
Thus, when you turn up the brightness of the light so that you can better see, you are increasing the amplitude of the light wave, which in turn increases the intensity of the light, seen from the increased brightness of the flash light.
A magnetic field is experienced by the charged particle in the +y direction.
Discussion:
- The right thumb rule states that the magnetic field lines will be perpendicular in the area to the conductive wire's left in which the electric potential is traveling.
- The direction of the current may be determined by looking at the positive charge's (X direction) motion. According to Fleming's left-hand rule, the force on a positive charge will be in the +y direction because the positive charge is moving in a leftward direction, which will also be the direction of the current.
Fleming's left-hand rule:
In accordance with Fleming's Left Hand Rule, the thumb, forefinger, and middle finger of the left hand should be positioned perpendicular to one another. The thumb should point in the path of the power exerted by the conductors, the forefinger should point in the magnetic field direction, and the middle finger should point in the path of the electric current.
