In the front is where the bass of everything comes from so it’s generally louder up there and toward the back there’s not as much bass to the music more just hearing the singer and other people screaming
Answer:
M_Train>> m_car a_train <a_car
Explanation:
To start the movement of the train or the car, the motorcycle applies a force on the wheels, which starts the acceleration in the case of the train, it has a much greater mass than that of the car, for which to obtain the same acceleration necessary a much greater force
a = F / m
as the mass of the train is greater than that of the car.
a_train <a_car
Something similar happens when the vehicles stop, the engine stops applying force forward and the brakes apply a force backward that creates a negative acceleration that slows down, again as the mass of the train is much greater than the of the car its negative acceleration is much less.
It is good to clarify that to compensate for this the trains have a braking system on all wheels
Answer:
b.
Explanation:
Parallax is the effect whereby the position or the direction of an object appears to differ, when viewed from different positions. e.g. through the view finder and lens of the camera.
a valid way of demonstrating parallax for yourself is by b.Hold up your hand in front of your face, and alternately close your left and right eyes.
Answer:
Explanation:
As we know that pressure between the cylinder and plunger is increased by 1.59 times
So this will make a net force upwards on the cylinder which is given as
now we will have
Here initial pressure is given as
now new pressure is given as
so we have force on the cylinder given as
now the acceleration is given as
Answer:
Velocity = frequency * wave length
Explanation:
Wave velocity is the measure of how fast the wave is being transmitted to a particular direction.
velocity implies both speed and direction as we know.
The velocity of a wave is equal to the product of its wavelength and frequency
where
- frequency - number of oscillations per unit time (measured in Hz)
- wave length - distance between corresponding points of two consecutive waves (measured in meters)
